Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

Part one of the final yafray commit. Totally updated blender shader in yafray, hopefully better matches blender results. Though ramps are now partially supported, they cannot work in all cases properly in yafray, and in fact are a bit useless probably as far as yafray is concerned. In fact the 'Result' ramp input mode is not supported at all, because it works on the total lighting result, and in a yafray shader this is not possible since it works per light. Also, since Blender and Yafray have totally different lighting models, the 'Energy' ramp input mode also won't generally give the same results as in Blender, since it works with light energy and in yafray this is different from Blender. Even worse, the only ramp shader that will work properly when used with GI is the 'Normal' ramp input mode. As contradictory as this might seem, at various stages of the GI process, lighting is not known, so properly getting light (ramp 'energy' mode) or shader information (ramp 'shader' mode, which depends on lighting) is not possible. Which all means that when the ramp is in 'energy' or 'shader' mode and using it with GI enabled, yafray can only 'see' the underlying material color, not the ramps, which results in a mix of the ramp colors (from direct light) with the material color (from indirect light). There is currently nothing that can be done about that. The supported texture mapping modes now includes raymir as well, transparency as far as texturing is concerned now works similar to Blender, with the exception that you still have to set alpha to a low value to get any transparency effect at all in yafray. So the Blender 'filter' parameter now also will affect yafray. All texture blending modes are now supported (same for ramps). 'Translu' and 'Amb' texture modulation are not supported. Texture interpolation can be switched off ('InterPol' switch in blender image texture button section). All Blender brdf models (aka 'shaders' for the Blender users) are now supported, and again, you won't necessarily get the same results as in Blender. The reason for that is partially of course the lighting differences, but also, not all Blender 'shader' implementations are actually correct, and copying those errors just for the sake of matching Blender results doesn't really seem like a good idea... Though this really is only the case for WardIso, less so for Minnaert and Blinn, which in yafray are more or less (but not totally) a copy of the Blender code. In any case, in practice those differences might not be too noticable at all (I hope). Continue to the next part...

Part one of the final yafray commit. Totally updated blender shader in yafray, hopefully better matches blender results. Though ramps are now partially supported, they cannot work in all cases properly in yafray, and in fact are a bit useless probably as far as yafray is concerned. In fact the 'Result' ramp input mode is not supported at all, because it works on the total lighting result, and in a yafray shader this is not possible since it works per light. Also, since Blender and Yafray have totally different lighting models, the 'Energy' ramp input mode also won't generally give the same results as in Blender, since it works with light energy and in yafray this is different from Blender. Even worse, the only ramp shader that will work properly when used with GI is the 'Normal' ramp input mode. As contradictory as this might seem, at various stages of the GI process, lighting is not known, so properly getting light (ramp 'energy' mode) or shader information (ramp 'shader' mode, which depends on lighting) is not possible. Which all means that when the ramp is in 'energy' or 'shader' mode and using it with GI enabled, yafray can only 'see' the underlying material color, not the ramps, which results in a mix of the ramp colors (from direct light) with the material color (from indirect light). There is currently nothing that can be done about that. The supported texture mapping modes now includes raymir as well, transparency as far as texturing is concerned now works similar to Blender, with the exception that you still have to set alpha to a low value to get any transparency effect at all in yafray. So the Blender 'filter' parameter now also will affect yafray. All texture blending modes are now supported (same for ramps). 'Translu' and 'Amb' texture modulation are not supported. Texture interpolation can be switched off ('InterPol' switch in blender image texture button section). All Blender brdf models (aka 'shaders' for the Blender users) are now supported, and again, you won't necessarily get the same results as in Blender. The reason for that is partially of course the lighting differences, but also, not all Blender 'shader' implementations are actually correct, and copying those errors just for the sake of matching Blender results doesn't really seem like a good idea... Though this really is only the case for WardIso, less so for Minnaert and Blinn, which in yafray are more or less (but not totally) a copy of the Blender code. In any case, in practice those differences might not be too noticable at all (I hope). Continue to the next part...

Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

params["color"] = yafray::parameter_t(yafray::color_t(matr->r, matr->g, matr->b));
Some small modifications. Absorption and Dispersion parameters now only visible when 'Ray Transp' enabled. WardIso specular amount scale to match Blender output. Updated halo spotlight 'samples' to use new yafray syntax. Quick addition for access to another yafray feature: When using HDR backgrounds for lighting ('SkyDome' of 'Full' GI methods), it is currently not always possible to get smooth lighting results. Especially HDR images with small lightsource can be very noisy, because currently yafray still relies on brute force random sampling. As a temporary simple solution (better options will be available in the 'next generation' yafray), yafray can do some processing on the image to smooth out all (or most) noise. Besides smooth lighting, this also has the advantage that AA will have less work to do, GI quality can be set to the lowest level and still get reasonably good results. Disadvantage however is that shadow definition is lost. To switch on this option, set the world image texture filter parameter to any value greater than 1.0 When 'filter' is 1.0 or less, normal hdr sampling is done as before. So, current fastest possible render settings for IBL: set texture image filter parameter of the background image to any value greater than 1.0, set GI to 'SkyDome' type, enable 'Cache', (possibly enable 'NoBump' when scene uses lots of bumpmapping), set 'Quality' menu to 'Use Blender AO settings', make sure AO is enabled in blender World buttons and set there the number of AO samples to 1. Should at least be good enough for previews.

Added some backward compatibility with old yafray blendershader. Because of missing parameters the material preset menu won't be as useful. Both glass presets will look the same because there is no 'filter' parameter in the old yafray for instance. So using the new Blender version with an old yafray version should work a bit better, though the other way around, using the new yafray with an old blender version, will generally not work as well. I added a few extra things. In 'yafray' panel re-arranged some buttons, and added a new button 'Clamp RGB'. This button will be enabled by default and helps to improve AA on high contrast edges in the image. When using bokeh however, it is best to switch this off, otherwise lens shaped highlights will be quite a bit less visible. Changed the 'extinction' parameter name to the probably more correct term 'absorption', though mathematically it works out the same. Also changed the behaviour of this color, it no longer specifies a color that will be removed as I wrote in the previous commit, but instead the actual color at one (blender) unit of distance. The 'Ds' (distance scale) button below the color sliders controls the scaling of this unit distance. What this means is that if you take the standard blender cube, which covers two units of distance by default, setting the distance scale button to 2.0 will make sure that the color you specified is exactly that color at that distance (provided the base color itself is white of course, or 'filter' is 0, otherwise it will be filtered by the base color too). Beyond this distance the color will get darker. The glow option for point/soft/sphere lights has a new parameter 'GloOfs', or glow offset. Setting this to a higher value then 0 will soften the central peak of the glow. Another unreported bug fix: For xml export, when yafray failed to render the xml file for some unknown reason, or because of other problems, the export code would still load the previously rendered image, this causes problems however if the image resolution is not the same as the current Blender buffer, and so could cause memory corruption or crashes. This is now taken into account. World image backgrounds now use the blender mapping settings as well, but only the 'AngMap', 'Sphere' and 'Tube' settings. But in yafray those last two, unlike Blender, cover the whole view, not just the upper half, so is not really fully compatible with yafray. So now you have to set one of these buttons too when loading a hdr lightprobe image. btw, something I forgot to mention in previous commits is that the exposure control using the texture brightness slider is no longer restricted to integer values. It is now a floating point value, so you're not restricted to the 0 1 and 2 slider positions anymore, anything in between will work too. And finally, display updating is now more like Blender, using the mouse cursor as frame counter for animation, etc.

Part one of the final yafray commit. Totally updated blender shader in yafray, hopefully better matches blender results. Though ramps are now partially supported, they cannot work in all cases properly in yafray, and in fact are a bit useless probably as far as yafray is concerned. In fact the 'Result' ramp input mode is not supported at all, because it works on the total lighting result, and in a yafray shader this is not possible since it works per light. Also, since Blender and Yafray have totally different lighting models, the 'Energy' ramp input mode also won't generally give the same results as in Blender, since it works with light energy and in yafray this is different from Blender. Even worse, the only ramp shader that will work properly when used with GI is the 'Normal' ramp input mode. As contradictory as this might seem, at various stages of the GI process, lighting is not known, so properly getting light (ramp 'energy' mode) or shader information (ramp 'shader' mode, which depends on lighting) is not possible. Which all means that when the ramp is in 'energy' or 'shader' mode and using it with GI enabled, yafray can only 'see' the underlying material color, not the ramps, which results in a mix of the ramp colors (from direct light) with the material color (from indirect light). There is currently nothing that can be done about that. The supported texture mapping modes now includes raymir as well, transparency as far as texturing is concerned now works similar to Blender, with the exception that you still have to set alpha to a low value to get any transparency effect at all in yafray. So the Blender 'filter' parameter now also will affect yafray. All texture blending modes are now supported (same for ramps). 'Translu' and 'Amb' texture modulation are not supported. Texture interpolation can be switched off ('InterPol' switch in blender image texture button section). All Blender brdf models (aka 'shaders' for the Blender users) are now supported, and again, you won't necessarily get the same results as in Blender. The reason for that is partially of course the lighting differences, but also, not all Blender 'shader' implementations are actually correct, and copying those errors just for the sake of matching Blender results doesn't really seem like a good idea... Though this really is only the case for WardIso, less so for Minnaert and Blinn, which in yafray are more or less (but not totally) a copy of the Blender code. In any case, in practice those differences might not be too noticable at all (I hope). Continue to the next part...

Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error.

Added some backward compatibility with old yafray blendershader. Because of missing parameters the material preset menu won't be as useful. Both glass presets will look the same because there is no 'filter' parameter in the old yafray for instance. So using the new Blender version with an old yafray version should work a bit better, though the other way around, using the new yafray with an old blender version, will generally not work as well. I added a few extra things. In 'yafray' panel re-arranged some buttons, and added a new button 'Clamp RGB'. This button will be enabled by default and helps to improve AA on high contrast edges in the image. When using bokeh however, it is best to switch this off, otherwise lens shaped highlights will be quite a bit less visible. Changed the 'extinction' parameter name to the probably more correct term 'absorption', though mathematically it works out the same. Also changed the behaviour of this color, it no longer specifies a color that will be removed as I wrote in the previous commit, but instead the actual color at one (blender) unit of distance. The 'Ds' (distance scale) button below the color sliders controls the scaling of this unit distance. What this means is that if you take the standard blender cube, which covers two units of distance by default, setting the distance scale button to 2.0 will make sure that the color you specified is exactly that color at that distance (provided the base color itself is white of course, or 'filter' is 0, otherwise it will be filtered by the base color too). Beyond this distance the color will get darker. The glow option for point/soft/sphere lights has a new parameter 'GloOfs', or glow offset. Setting this to a higher value then 0 will soften the central peak of the glow. Another unreported bug fix: For xml export, when yafray failed to render the xml file for some unknown reason, or because of other problems, the export code would still load the previously rendered image, this causes problems however if the image resolution is not the same as the current Blender buffer, and so could cause memory corruption or crashes. This is now taken into account. World image backgrounds now use the blender mapping settings as well, but only the 'AngMap', 'Sphere' and 'Tube' settings. But in yafray those last two, unlike Blender, cover the whole view, not just the upper half, so is not really fully compatible with yafray. So now you have to set one of these buttons too when loading a hdr lightprobe image. btw, something I forgot to mention in previous commits is that the exposure control using the texture brightness slider is no longer restricted to integer values. It is now a floating point value, so you're not restricted to the 0 1 and 2 slider positions anymore, anything in between will work too. And finally, display updating is now more like Blender, using the mouse cursor as frame counter for animation, etc.

Part one of the final yafray commit. Totally updated blender shader in yafray, hopefully better matches blender results. Though ramps are now partially supported, they cannot work in all cases properly in yafray, and in fact are a bit useless probably as far as yafray is concerned. In fact the 'Result' ramp input mode is not supported at all, because it works on the total lighting result, and in a yafray shader this is not possible since it works per light. Also, since Blender and Yafray have totally different lighting models, the 'Energy' ramp input mode also won't generally give the same results as in Blender, since it works with light energy and in yafray this is different from Blender. Even worse, the only ramp shader that will work properly when used with GI is the 'Normal' ramp input mode. As contradictory as this might seem, at various stages of the GI process, lighting is not known, so properly getting light (ramp 'energy' mode) or shader information (ramp 'shader' mode, which depends on lighting) is not possible. Which all means that when the ramp is in 'energy' or 'shader' mode and using it with GI enabled, yafray can only 'see' the underlying material color, not the ramps, which results in a mix of the ramp colors (from direct light) with the material color (from indirect light). There is currently nothing that can be done about that. The supported texture mapping modes now includes raymir as well, transparency as far as texturing is concerned now works similar to Blender, with the exception that you still have to set alpha to a low value to get any transparency effect at all in yafray. So the Blender 'filter' parameter now also will affect yafray. All texture blending modes are now supported (same for ramps). 'Translu' and 'Amb' texture modulation are not supported. Texture interpolation can be switched off ('InterPol' switch in blender image texture button section). All Blender brdf models (aka 'shaders' for the Blender users) are now supported, and again, you won't necessarily get the same results as in Blender. The reason for that is partially of course the lighting differences, but also, not all Blender 'shader' implementations are actually correct, and copying those errors just for the sake of matching Blender results doesn't really seem like a good idea... Though this really is only the case for WardIso, less so for Minnaert and Blinn, which in yafray are more or less (but not totally) a copy of the Blender code. In any case, in practice those differences might not be too noticable at all (I hope). Continue to the next part...

Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

Part one of the final yafray commit. Totally updated blender shader in yafray, hopefully better matches blender results. Though ramps are now partially supported, they cannot work in all cases properly in yafray, and in fact are a bit useless probably as far as yafray is concerned. In fact the 'Result' ramp input mode is not supported at all, because it works on the total lighting result, and in a yafray shader this is not possible since it works per light. Also, since Blender and Yafray have totally different lighting models, the 'Energy' ramp input mode also won't generally give the same results as in Blender, since it works with light energy and in yafray this is different from Blender. Even worse, the only ramp shader that will work properly when used with GI is the 'Normal' ramp input mode. As contradictory as this might seem, at various stages of the GI process, lighting is not known, so properly getting light (ramp 'energy' mode) or shader information (ramp 'shader' mode, which depends on lighting) is not possible. Which all means that when the ramp is in 'energy' or 'shader' mode and using it with GI enabled, yafray can only 'see' the underlying material color, not the ramps, which results in a mix of the ramp colors (from direct light) with the material color (from indirect light). There is currently nothing that can be done about that.

Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

Render Instancing ================= Big commit, but little user visible changes. - Dupliverts and duplifaces are now rendered as instances, instead of storing all of the geometry for each dupli, now an instance is created with a matrix transform refering to the source object. This should allow us to render tree leaves more memory efficient. - Radiosity and to some degree raytracing of such objects is not really efficient still. For radiosity this is fundamentally hard to solve, but raytracing an octree could be created for each object, but the current octree code with it's fixed size doesn't allow this efficiently. - The regression tests survived, but with I expect that some bugs will pop up .. hopefully not too many :). Implementation Notes ==================== - Dupligroups and linked meshes are not rendered as instances yet, since they can in fact be different due to various reasons, instancing of these types of duplis that are the same can be added for them at a later point. - Each ObjectRen now stores it's own database, instead of there being one big databases of faces, verts, .. . Which objects that are actually rendered are defined by the list of ObjectRenInstances, which all refer to an ObjectRen. - Homogeneous coordinatess and clipping is now not stored in vertices anymore, but instead computed on the fly. This couldn't work for instances. That does mean some extra computation has to be done, but memory lookups can be slow too, and this saves some memory. Overall I didn't find a significant speed impact. - OSA rendering for solid and ztransp now is different. Instead of e.g. going 8 times over the databases times and rendering the z-buffer, it now goes over the database once and renders each polygon 8 times. That was necessary to keep instances efficient, and can also give some performance improvement without instances. - There was already instancing support in the yafray export code, now it uses Blender's render instances for export. - UV and color layer storage in the render was a bit messy before, now should be easier to understand. - convertblender.c was reorganized somewhat. Regular render, speedvector and baking now use a single function to create the database, previously there was code duplicated for it. - Some of these changes were done with future multithreading of scene and shadow buffer creation in mind, though especially for scene creation much work remains to be done to make it threadsafe, since it also involves a lot of code from blenkernel, and there is an ugly conflict with the way dupli groups work here .. though in the render code itself it's almost there.

Render Instancing ================= Big commit, but little user visible changes. - Dupliverts and duplifaces are now rendered as instances, instead of storing all of the geometry for each dupli, now an instance is created with a matrix transform refering to the source object. This should allow us to render tree leaves more memory efficient. - Radiosity and to some degree raytracing of such objects is not really efficient still. For radiosity this is fundamentally hard to solve, but raytracing an octree could be created for each object, but the current octree code with it's fixed size doesn't allow this efficiently. - The regression tests survived, but with I expect that some bugs will pop up .. hopefully not too many :). Implementation Notes ==================== - Dupligroups and linked meshes are not rendered as instances yet, since they can in fact be different due to various reasons, instancing of these types of duplis that are the same can be added for them at a later point. - Each ObjectRen now stores it's own database, instead of there being one big databases of faces, verts, .. . Which objects that are actually rendered are defined by the list of ObjectRenInstances, which all refer to an ObjectRen. - Homogeneous coordinatess and clipping is now not stored in vertices anymore, but instead computed on the fly. This couldn't work for instances. That does mean some extra computation has to be done, but memory lookups can be slow too, and this saves some memory. Overall I didn't find a significant speed impact. - OSA rendering for solid and ztransp now is different. Instead of e.g. going 8 times over the databases times and rendering the z-buffer, it now goes over the database once and renders each polygon 8 times. That was necessary to keep instances efficient, and can also give some performance improvement without instances. - There was already instancing support in the yafray export code, now it uses Blender's render instances for export. - UV and color layer storage in the render was a bit messy before, now should be easier to understand. - convertblender.c was reorganized somewhat. Regular render, speedvector and baking now use a single function to create the database, previously there was code duplicated for it. - Some of these changes were done with future multithreading of scene and shadow buffer creation in mind, though especially for scene creation much work remains to be done to make it threadsafe, since it also involves a lot of code from blenkernel, and there is an ugly conflict with the way dupli groups work here .. though in the render code itself it's almost there.

Giant commit! A full detailed description of this will be done later... is several days of work. Here's a summary: Render: - Full cleanup of render code, removing *all* globals and bad level calls all over blender. Render module is now not called abusive anymore - API-fied calls to rendering - Full recode of internal render pipeline. Is now rendering tiles by default, prepared for much smarter 'bucket' render later. - Each thread now can render a full part - Renders were tested with 4 threads, goes fine, apart from some lookup tables in softshadow and AO still - Rendering is prepared to do multiple layers and passes - No single 32 bits trick in render code anymore, all 100% floats now. Writing images/movies - moved writing images to blender kernel (bye bye 'schrijfplaatje'!) - made a new Movie handle system, also in kernel. This will enable much easier use of movies in Blender PreviewRender: - Using new render API, previewrender (in buttons) now uses regular render code to generate images. - new datafile 'preview.blend.c' has the preview scenes in it - previews get rendered in exact displayed size (1 pixel = 1 pixel) 3D Preview render - new; press Pkey in 3d window, for a panel that continuously renders (pkey is for games, i know... but we dont do that in orange now!) - this render works nearly identical to buttons-preview render, so it stops rendering on any event (mouse, keyboard, etc) - on moving/scaling the panel, the render code doesn't recreate all geometry - same for shifting/panning view - all other operations (now) regenerate the full render database still. - this is WIP... but big fun, especially for simple scenes! Compositor - Using same node system as now in use for shaders, you can composit images - works pretty straightforward... needs much more options/tools and integration with rendering still - is not threaded yet, nor is so smart to only recalculate changes... will be done soon! - the "Render Result" node will get all layers/passes as output sockets - The "Output" node renders to a builtin image, which you can view in the Image window. (yes, output nodes to render-result, and to files, is on the list!) The Bad News - "Unified Render" is removed. It might come back in some stage, but this system should be built from scratch. I can't really understand this code... I expect it is not much needed, especially with advanced layer/passes control - Panorama render, Field render, Motion blur, is not coded yet... (I had to recode every single feature in render, so...!) - Lens Flare is also not back... needs total revision, might become composit effect though (using zbuffer for visibility) - Part render is gone! (well, thats obvious, its default now). - The render window is only restored with limited functionality... I am going to check first the option to render to a Image window, so Blender can become a true single-window application. :) For example, the 'Spare render buffer' (jkey) doesnt work. - Render with border, now default creates a smaller image - No zbuffers are written yet... on the todo! - Scons files and MSVC will need work to get compiling again OK... thats what I can quickly recall. Now go compiling!

string type="";
Major update, all implemented a bit in a hurry, and probably will need bugfixes at some point. Extended the range of the depth and cdepth parameters as reqested by leope. Bumpmapping should now be a bit more similar to the Blender render. Added support for all remaining lightsources in yafray, tried to make use of as much of the existing Blender parameters as possible. Blender Lamp: added switch to enable rendering with shadowbuffer ('softlight' in yafray). All other parameters are similar to the Blender settings, for yafray both the bias parameter and the shadowbuffer size can be lower than equivalent Blender settings, since the yafray buffer is floating point. Remember that 6 shadowmaps are created in this case, so can use quite a bit of memory with large buffer settings. When 'ray shadow' is enabled for this lamp type, it is possible to set a light radius to create a spherical arealight source ('spherelight' in yafray), when this is 0, it is exported as a pointlight instead. Blender Spot: as in Blender now supports 'halo' rendering. Halo spots always use shadowbuffers, so when enabled the buttons for shadowmap settings will appear. The 'ray shadow' button can still be used to disable shadows cast onto other objects, independent of halo shadows. One thing to remember, halo's don't work with empty backgrounds, something must be behind the spotlight for it to be visible. And finally, the photonlight: probably the most confusing (as more things related to yafray), the photonlight is not a real lightsource, it is only used as a source to shoot photons from. Since indirect lighting is already supported (and looks better as well) only caustics mode is supported. So to be able to use this properly other lightsources must be used with it. For the photonlighting to be 'correct' similar lightsettings as for the 'source' light are needed. Probably the best way to do this, when you are happy with the lighting setup you have, and want to add caustics, copy the light you want to enable for caustics (shift-D) and leave everything as is, then change the mode to 'Photon'. To not waiste any photons, the photonlight behaves similar to the spotlight, you can set the width of the beam with the 'angle' parameter. Make sure that any object that needs to cast caustics is within that beam, make the beam width as small as possible to tightly fit the object. The following other parameters can be set: -photons: the number of photons to shoot. -search: the number of photons to search when rendering, the higher, the blurrier the caustics. -depth: the amount of photon bounces allowed, since the primary use is for caustics, you probably best set this to the same level as the 'ray depth' parameter. -Blur: this controls the amount of caustics blur (in addition to the search parameter), very low values will cause very sharp caustics, which when used with a low photonnumber, probably lead to only some noisy specks being rendered. -Use QMC: Use quasi monte carlo sampling, can lead to cleaner results, but also can sometimes cause patterns. Since the photonlight has no meaning to Blender, when using photonlights and switching back to the internal render, the light doesn't do anything, and no type button will be selected. The lightsource can still be selected, but unless switching to yafray, no parameters can set. Apologies to Anexus, I had no time to really do something with your code, I'll still look at it later, to see if I can improve anything in my implementation.

// TODO: add decay setting in yafray
Major update, all implemented a bit in a hurry, and probably will need bugfixes at some point. Extended the range of the depth and cdepth parameters as reqested by leope. Bumpmapping should now be a bit more similar to the Blender render. Added support for all remaining lightsources in yafray, tried to make use of as much of the existing Blender parameters as possible. Blender Lamp: added switch to enable rendering with shadowbuffer ('softlight' in yafray). All other parameters are similar to the Blender settings, for yafray both the bias parameter and the shadowbuffer size can be lower than equivalent Blender settings, since the yafray buffer is floating point. Remember that 6 shadowmaps are created in this case, so can use quite a bit of memory with large buffer settings. When 'ray shadow' is enabled for this lamp type, it is possible to set a light radius to create a spherical arealight source ('spherelight' in yafray), when this is 0, it is exported as a pointlight instead. Blender Spot: as in Blender now supports 'halo' rendering. Halo spots always use shadowbuffers, so when enabled the buttons for shadowmap settings will appear. The 'ray shadow' button can still be used to disable shadows cast onto other objects, independent of halo shadows. One thing to remember, halo's don't work with empty backgrounds, something must be behind the spotlight for it to be visible. And finally, the photonlight: probably the most confusing (as more things related to yafray), the photonlight is not a real lightsource, it is only used as a source to shoot photons from. Since indirect lighting is already supported (and looks better as well) only caustics mode is supported. So to be able to use this properly other lightsources must be used with it. For the photonlighting to be 'correct' similar lightsettings as for the 'source' light are needed. Probably the best way to do this, when you are happy with the lighting setup you have, and want to add caustics, copy the light you want to enable for caustics (shift-D) and leave everything as is, then change the mode to 'Photon'. To not waiste any photons, the photonlight behaves similar to the spotlight, you can set the width of the beam with the 'angle' parameter. Make sure that any object that needs to cast caustics is within that beam, make the beam width as small as possible to tightly fit the object. The following other parameters can be set: -photons: the number of photons to shoot. -search: the number of photons to search when rendering, the higher, the blurrier the caustics. -depth: the amount of photon bounces allowed, since the primary use is for caustics, you probably best set this to the same level as the 'ray depth' parameter. -Blur: this controls the amount of caustics blur (in addition to the search parameter), very low values will cause very sharp caustics, which when used with a low photonnumber, probably lead to only some noisy specks being rendered. -Use QMC: Use quasi monte carlo sampling, can lead to cleaner results, but also can sometimes cause patterns. Since the photonlight has no meaning to Blender, when using photonlights and switching back to the internal render, the light doesn't do anything, and no type button will be selected. The lightsource can still be selected, but unless switching to yafray, no parameters can set. Apologies to Anexus, I had no time to really do something with your code, I'll still look at it later, to see if I can improve anything in my implementation.

Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

Added some backward compatibility with old yafray blendershader. Because of missing parameters the material preset menu won't be as useful. Both glass presets will look the same because there is no 'filter' parameter in the old yafray for instance. So using the new Blender version with an old yafray version should work a bit better, though the other way around, using the new yafray with an old blender version, will generally not work as well. I added a few extra things. In 'yafray' panel re-arranged some buttons, and added a new button 'Clamp RGB'. This button will be enabled by default and helps to improve AA on high contrast edges in the image. When using bokeh however, it is best to switch this off, otherwise lens shaped highlights will be quite a bit less visible. Changed the 'extinction' parameter name to the probably more correct term 'absorption', though mathematically it works out the same. Also changed the behaviour of this color, it no longer specifies a color that will be removed as I wrote in the previous commit, but instead the actual color at one (blender) unit of distance. The 'Ds' (distance scale) button below the color sliders controls the scaling of this unit distance. What this means is that if you take the standard blender cube, which covers two units of distance by default, setting the distance scale button to 2.0 will make sure that the color you specified is exactly that color at that distance (provided the base color itself is white of course, or 'filter' is 0, otherwise it will be filtered by the base color too). Beyond this distance the color will get darker. The glow option for point/soft/sphere lights has a new parameter 'GloOfs', or glow offset. Setting this to a higher value then 0 will soften the central peak of the glow. Another unreported bug fix: For xml export, when yafray failed to render the xml file for some unknown reason, or because of other problems, the export code would still load the previously rendered image, this causes problems however if the image resolution is not the same as the current Blender buffer, and so could cause memory corruption or crashes. This is now taken into account. World image backgrounds now use the blender mapping settings as well, but only the 'AngMap', 'Sphere' and 'Tube' settings. But in yafray those last two, unlike Blender, cover the whole view, not just the upper half, so is not really fully compatible with yafray. So now you have to set one of these buttons too when loading a hdr lightprobe image. btw, something I forgot to mention in previous commits is that the exposure control using the texture brightness slider is no longer restricted to integer values. It is now a floating point value, so you're not restricted to the 0 1 and 2 slider positions anymore, anything in between will work too. And finally, display updating is now more like Blender, using the mouse cursor as frame counter for animation, etc.

Part one of the final yafray commit. Totally updated blender shader in yafray, hopefully better matches blender results. Though ramps are now partially supported, they cannot work in all cases properly in yafray, and in fact are a bit useless probably as far as yafray is concerned. In fact the 'Result' ramp input mode is not supported at all, because it works on the total lighting result, and in a yafray shader this is not possible since it works per light. Also, since Blender and Yafray have totally different lighting models, the 'Energy' ramp input mode also won't generally give the same results as in Blender, since it works with light energy and in yafray this is different from Blender. Even worse, the only ramp shader that will work properly when used with GI is the 'Normal' ramp input mode. As contradictory as this might seem, at various stages of the GI process, lighting is not known, so properly getting light (ramp 'energy' mode) or shader information (ramp 'shader' mode, which depends on lighting) is not possible. Which all means that when the ramp is in 'energy' or 'shader' mode and using it with GI enabled, yafray can only 'see' the underlying material color, not the ramps, which results in a mix of the ramp colors (from direct light) with the material color (from indirect light). There is currently nothing that can be done about that. The supported texture mapping modes now includes raymir as well, transparency as far as texturing is concerned now works similar to Blender, with the exception that you still have to set alpha to a low value to get any transparency effect at all in yafray. So the Blender 'filter' parameter now also will affect yafray. All texture blending modes are now supported (same for ramps). 'Translu' and 'Amb' texture modulation are not supported. Texture interpolation can be switched off ('InterPol' switch in blender image texture button section). All Blender brdf models (aka 'shaders' for the Blender users) are now supported, and again, you won't necessarily get the same results as in Blender. The reason for that is partially of course the lighting differences, but also, not all Blender 'shader' implementations are actually correct, and copying those errors just for the sake of matching Blender results doesn't really seem like a good idea... Though this really is only the case for WardIso, less so for Minnaert and Blinn, which in yafray are more or less (but not totally) a copy of the Blender code. In any case, in practice those differences might not be too noticable at all (I hope). Continue to the next part...

// color already premultiplied by energy, so only need distance here
Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

float pwr = 1; // default for sun/hemi, distance irrelevant
Major update, all implemented a bit in a hurry, and probably will need bugfixes at some point. Extended the range of the depth and cdepth parameters as reqested by leope. Bumpmapping should now be a bit more similar to the Blender render. Added support for all remaining lightsources in yafray, tried to make use of as much of the existing Blender parameters as possible. Blender Lamp: added switch to enable rendering with shadowbuffer ('softlight' in yafray). All other parameters are similar to the Blender settings, for yafray both the bias parameter and the shadowbuffer size can be lower than equivalent Blender settings, since the yafray buffer is floating point. Remember that 6 shadowmaps are created in this case, so can use quite a bit of memory with large buffer settings. When 'ray shadow' is enabled for this lamp type, it is possible to set a light radius to create a spherical arealight source ('spherelight' in yafray), when this is 0, it is exported as a pointlight instead. Blender Spot: as in Blender now supports 'halo' rendering. Halo spots always use shadowbuffers, so when enabled the buttons for shadowmap settings will appear. The 'ray shadow' button can still be used to disable shadows cast onto other objects, independent of halo shadows. One thing to remember, halo's don't work with empty backgrounds, something must be behind the spotlight for it to be visible. And finally, the photonlight: probably the most confusing (as more things related to yafray), the photonlight is not a real lightsource, it is only used as a source to shoot photons from. Since indirect lighting is already supported (and looks better as well) only caustics mode is supported. So to be able to use this properly other lightsources must be used with it. For the photonlighting to be 'correct' similar lightsettings as for the 'source' light are needed. Probably the best way to do this, when you are happy with the lighting setup you have, and want to add caustics, copy the light you want to enable for caustics (shift-D) and leave everything as is, then change the mode to 'Photon'. To not waiste any photons, the photonlight behaves similar to the spotlight, you can set the width of the beam with the 'angle' parameter. Make sure that any object that needs to cast caustics is within that beam, make the beam width as small as possible to tightly fit the object. The following other parameters can be set: -photons: the number of photons to shoot. -search: the number of photons to search when rendering, the higher, the blurrier the caustics. -depth: the amount of photon bounces allowed, since the primary use is for caustics, you probably best set this to the same level as the 'ray depth' parameter. -Blur: this controls the amount of caustics blur (in addition to the search parameter), very low values will cause very sharp caustics, which when used with a low photonnumber, probably lead to only some noisy specks being rendered. -Use QMC: Use quasi monte carlo sampling, can lead to cleaner results, but also can sometimes cause patterns. Since the photonlight has no meaning to Blender, when using photonlights and switching back to the internal render, the light doesn't do anything, and no type button will be selected. The lightsource can still be selected, but unless switching to yafray, no parameters can set. Apologies to Anexus, I had no time to really do something with your code, I'll still look at it later, to see if I can improve anything in my implementation.

Some small modifications. Absorption and Dispersion parameters now only visible when 'Ray Transp' enabled. WardIso specular amount scale to match Blender output. Updated halo spotlight 'samples' to use new yafray syntax. Quick addition for access to another yafray feature: When using HDR backgrounds for lighting ('SkyDome' of 'Full' GI methods), it is currently not always possible to get smooth lighting results. Especially HDR images with small lightsource can be very noisy, because currently yafray still relies on brute force random sampling. As a temporary simple solution (better options will be available in the 'next generation' yafray), yafray can do some processing on the image to smooth out all (or most) noise. Besides smooth lighting, this also has the advantage that AA will have less work to do, GI quality can be set to the lowest level and still get reasonably good results. Disadvantage however is that shadow definition is lost. To switch on this option, set the world image texture filter parameter to any value greater than 1.0 When 'filter' is 1.0 or less, normal hdr sampling is done as before. So, current fastest possible render settings for IBL: set texture image filter parameter of the background image to any value greater than 1.0, set GI to 'SkyDome' type, enable 'Cache', (possibly enable 'NoBump' when scene uses lots of bumpmapping), set 'Quality' menu to 'Use Blender AO settings', make sure AO is enabled in blender World buttons and set there the number of AO samples to 1. Should at least be good enough for previews.

Major update, all implemented a bit in a hurry, and probably will need bugfixes at some point. Extended the range of the depth and cdepth parameters as reqested by leope. Bumpmapping should now be a bit more similar to the Blender render. Added support for all remaining lightsources in yafray, tried to make use of as much of the existing Blender parameters as possible. Blender Lamp: added switch to enable rendering with shadowbuffer ('softlight' in yafray). All other parameters are similar to the Blender settings, for yafray both the bias parameter and the shadowbuffer size can be lower than equivalent Blender settings, since the yafray buffer is floating point. Remember that 6 shadowmaps are created in this case, so can use quite a bit of memory with large buffer settings. When 'ray shadow' is enabled for this lamp type, it is possible to set a light radius to create a spherical arealight source ('spherelight' in yafray), when this is 0, it is exported as a pointlight instead. Blender Spot: as in Blender now supports 'halo' rendering. Halo spots always use shadowbuffers, so when enabled the buttons for shadowmap settings will appear. The 'ray shadow' button can still be used to disable shadows cast onto other objects, independent of halo shadows. One thing to remember, halo's don't work with empty backgrounds, something must be behind the spotlight for it to be visible. And finally, the photonlight: probably the most confusing (as more things related to yafray), the photonlight is not a real lightsource, it is only used as a source to shoot photons from. Since indirect lighting is already supported (and looks better as well) only caustics mode is supported. So to be able to use this properly other lightsources must be used with it. For the photonlighting to be 'correct' similar lightsettings as for the 'source' light are needed. Probably the best way to do this, when you are happy with the lighting setup you have, and want to add caustics, copy the light you want to enable for caustics (shift-D) and leave everything as is, then change the mode to 'Photon'. To not waiste any photons, the photonlight behaves similar to the spotlight, you can set the width of the beam with the 'angle' parameter. Make sure that any object that needs to cast caustics is within that beam, make the beam width as small as possible to tightly fit the object. The following other parameters can be set: -photons: the number of photons to shoot. -search: the number of photons to search when rendering, the higher, the blurrier the caustics. -depth: the amount of photon bounces allowed, since the primary use is for caustics, you probably best set this to the same level as the 'ray depth' parameter. -Blur: this controls the amount of caustics blur (in addition to the search parameter), very low values will cause very sharp caustics, which when used with a low photonnumber, probably lead to only some noisy specks being rendered. -Use QMC: Use quasi monte carlo sampling, can lead to cleaner results, but also can sometimes cause patterns. Since the photonlight has no meaning to Blender, when using photonlights and switching back to the internal render, the light doesn't do anything, and no type button will be selected. The lightsource can still be selected, but unless switching to yafray, no parameters can set. Apologies to Anexus, I had no time to really do something with your code, I'll still look at it later, to see if I can improve anything in my implementation.

Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want.

The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

Second and final commit for this version of the yafray export code (probably, you never know of course...) Not quite complete, but due to lack of time as good as it will get for now. From the previous commit, forgot to report that basic fog is supported as well. Though because I had not much time to complete the code, it is sort of unfinished, and you will have to tweak parameters specifically for yafray again. It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well.

It uses only the world horizon color, and only uses the Blender mist distance setting. Textures now support checker clip mode. Fixed possibly all 'duplilist non-empty' errors, though it could hide the real cause of the error. AA is no longer enabled automatically for certain GI quality settings, I thought it best to leave it to the user to decide. SkyDome GI mode now supports cache as well. There is a new option in the GI quality menu 'Use Blender AO settings', which will as it says use the most important AO settings for the skydome parameters. The only AO parameters used are 'Samples', 'Dist' and the random sampling switch, which unlike in Blender you might want to use more often, since the QMC sampling used in yafray can result in visible patterns or a dithering type look. 'Random' is not completely random in yafray however, it is actually jittered (stratified) sampling. Using an occlusion cache, doesn't necessarily mean that you will always get much shorter render times. As with 'full' GI and cache, one problem is bumpmaps, when using bump (or normal) maps, the sampling will be much more dense, using lots more rendertime. As a temporary fix there is a button 'NoBump', but this also has the side effect that in areas of total indirect light (or when used with SkyDome cache) no bumpmapping will be visible. It is therefor best used with some direct light as well. For SkyDome with cache, and strong bumpmapping it might actually not make much difference, since for low distance values you can usually get away with low sample values as well. The entire material panel is now replaced by another panel to show only the parameters important to yafray and add some new ones as well. Since lots of users (especially yafray beginners) have had problems getting certain material aspects right, there is now a material preset menu available to hopefully solve some of the most common "How do I do this? It doesn't work!" questions seen in various forums. Choosing an option from this menu will set the required parameters to default values for yafray, and you can work your way from there to tweak it something you want. Most buttons are copies of the same Blender parameters, with some variations. Just like Blender 'Ray Mirror' enables reflection, 'Ray Transp' enables refraction. You can use 'ZTransp' for materials that have texture maps with alpha channels. Again, same as Blender 'rayMir' sets the amount of reflection. Next button 'frsOfs' however controls fresnel offset, meaning that when this is set to 1, you will get no fresnel effect and when set to 5, reflection is totally determined by fresnel, which is important for realistic glass/metals/etc. IOR is self-explanatory (...), same as Blender. When you have 'Ray Transp' enabled, the blender 'filter' button will appear next to the IOR button. This has the same effect as in Blender. Below that there are some new parameters, 'Ext.Color' sets the extinction color for transparent materials. Usually, in real transparent materials, light loses some of it's energy the further it has to travel through the object. This effect can be simulated with this parameter. Thing to look out for is that it specifies the color which will be REMOVED after traveling through the object. What this means is that say you have a clear white glass sphere, and set the extinction color to a strong blue, the result will be a very yellow object when rendered. Next to the color sliders, there is another set of three parameters, with which you can enable color dispersion for transparent objects. 'Pwr' sets the amount of dispersion, the higher, the more dispersion (the more colorful the result). (For real world materials, this number can be found or derived from data in various glass catalogues) The 'Samples' button below that sets the number of samples used, minimum values are around 7-10, and for very strong dispersion you might need a lot more. As usual, this also means an increase in render time of course, but to simulate realistic materials, you shouldn't really need more than 25 samples. In addition to that, when using low sample numbers, but to still get a good spread of colors, you can enable the jitter button, but this will also add noise. Point/soft(point with shadowbuffer) or sphere lights (light with radius), have a new option to add a simple glow effect, so that lights can be made visible. NOTE: just like spotlight halo's, glow is not visible against the background, there must be another object behind it. Simplest solution is to use a large black shadeless plane behind your scene. The glow intensity can be set with the 'GlowInt' parameter (use very low values around 0.01 even lower), and you can choose from two different types with the 'GlowType' button (which don't look much different, but type 1 is probably better, type 0 faster). And that's it, with apologies for the still missing features and full support in general, but this will have to do for now.

Added some backward compatibility with old yafray blendershader. Because of missing parameters the material preset menu won't be as useful. Both glass presets will look the same because there is no 'filter' parameter in the old yafray for instance. So using the new Blender version with an old yafray version should work a bit better, though the other way around, using the new yafray with an old blender version, will generally not work as well. I added a few extra things. In 'yafray' panel re-arranged some buttons, and added a new button 'Clamp RGB'. This button will be enabled by default and helps to improve AA on high contrast edges in the image. When using bokeh however, it is best to switch this off, otherwise lens shaped highlights will be quite a bit less visible. Changed the 'extinction' parameter name to the probably more correct term 'absorption', though mathematically it works out the same. Also changed the behaviour of this color, it no longer specifies a color that will be removed as I wrote in the previous commit, but instead the actual color at one (blender) unit of distance. The 'Ds' (distance scale) button below the color sliders controls the scaling of this unit distance. What this means is that if you take the standard blender cube, which covers two units of distance by default, setting the distance scale button to 2.0 will make sure that the color you specified is exactly that color at that distance (provided the base color itself is white of course, or 'filter' is 0, otherwise it will be filtered by the base color too). Beyond this distance the color will get darker. The glow option for point/soft/sphere lights has a new parameter 'GloOfs', or glow offset. Setting this to a higher value then 0 will soften the central peak of the glow. Another unreported bug fix: For xml export, when yafray failed to render the xml file for some unknown reason, or because of other problems, the export code would still load the previously rendered image, this causes problems however if the image resolution is not the same as the current Blender buffer, and so could cause memory corruption or crashes. This is now taken into account. World image backgrounds now use the blender mapping settings as well, but only the 'AngMap', 'Sphere' and 'Tube' settings. But in yafray those last two, unlike Blender, cover the whole view, not just the upper half, so is not really fully compatible with yafray. So now you have to set one of these buttons too when loading a hdr lightprobe image. btw, something I forgot to mention in previous commits is that the exposure control using the texture brightness slider is no longer restricted to integer values. It is now a floating point value, so you're not restricted to the 0 1 and 2 slider positions anymore, anything in between will work too. And finally, display updating is now more like Blender, using the mouse cursor as frame counter for animation, etc.

Some small modifications. Absorption and Dispersion parameters now only visible when 'Ray Transp' enabled. WardIso specular amount scale to match Blender output. Updated halo spotlight 'samples' to use new yafray syntax. Quick addition for access to another yafray feature: When using HDR backgrounds for lighting ('SkyDome' of 'Full' GI methods), it is currently not always possible to get smooth lighting results. Especially HDR images with small lightsource can be very noisy, because currently yafray still relies on brute force random sampling. As a temporary simple solution (better options will be available in the 'next generation' yafray), yafray can do some processing on the image to smooth out all (or most) noise. Besides smooth lighting, this also has the advantage that AA will have less work to do, GI quality can be set to the lowest level and still get reasonably good results. Disadvantage however is that shadow definition is lost. To switch on this option, set the world image texture filter parameter to any value greater than 1.0 When 'filter' is 1.0 or less, normal hdr sampling is done as before. So, current fastest possible render settings for IBL: set texture image filter parameter of the background image to any value greater than 1.0, set GI to 'SkyDome' type, enable 'Cache', (possibly enable 'NoBump' when scene uses lots of bumpmapping), set 'Quality' menu to 'Use Blender AO settings', make sure AO is enabled in blender World buttons and set there the number of AO samples to 1. Should at least be good enough for previews.

Another unreported bug fix: For xml export, when yafray failed to render the xml file for some unknown reason, or because of other problems, the export code would still load the previously rendered image, this causes problems however if the image resolution is not the same as the current Blender buffer, and so could cause memory corruption or crashes. This is now taken into account. World image backgrounds now use the blender mapping settings as well, but only the 'AngMap', 'Sphere' and 'Tube' settings. But in yafray those last two, unlike Blender, cover the whole view, not just the upper half, so is not really fully compatible with yafray. So now you have to set one of these buttons too when loading a hdr lightprobe image. btw, something I forgot to mention in previous commits is that the exposure control using the texture brightness slider is no longer restricted to integer values. It is now a floating point value, so you're not restricted to the 0 1 and 2 slider positions anymore, anything in between will work too. And finally, display updating is now more like Blender, using the mouse cursor as frame counter for animation, etc.

Added some backward compatibility with old yafray blendershader. Because of missing parameters the material preset menu won't be as useful. Both glass presets will look the same because there is no 'filter' parameter in the old yafray for instance. So using the new Blender version with an old yafray version should work a bit better, though the other way around, using the new yafray with an old blender version, will generally not work as well. I added a few extra things. In 'yafray' panel re-arranged some buttons, and added a new button 'Clamp RGB'. This button will be enabled by default and helps to improve AA on high contrast edges in the image. When using bokeh however, it is best to switch this off, otherwise lens shaped highlights will be quite a bit less visible. Changed the 'extinction' parameter name to the probably more correct term 'absorption', though mathematically it works out the same. Also changed the behaviour of this color, it no longer specifies a color that will be removed as I wrote in the previous commit, but instead the actual color at one (blender) unit of distance. The 'Ds' (distance scale) button below the color sliders controls the scaling of this unit distance. What this means is that if you take the standard blender cube, which covers two units of distance by default, setting the distance scale button to 2.0 will make sure that the color you specified is exactly that color at that distance (provided the base color itself is white of course, or 'filter' is 0, otherwise it will be filtered by the base color too). Beyond this distance the color will get darker. The glow option for point/soft/sphere lights has a new parameter 'GloOfs', or glow offset. Setting this to a higher value then 0 will soften the central peak of the glow. Another unreported bug fix: For xml export, when yafray failed to render the xml file for some unknown reason, or because of other problems, the export code would still load the previously rendered image, this causes problems however if the image resolution is not the same as the current Blender buffer, and so could cause memory corruption or crashes.
