Changes to Color Management After testing and feedback, I've decided to slightly modify the way color management works internally. While the previous method worked well for rendering, was a smaller transition and had some advantages over this new method, it was a bit more ambiguous, and was making things difficult for other areas such as compositing. This implementation now considers all color data (with only a couple of exceptions such as brush colors) to be stored in linear RGB color space, rather than sRGB as previously. This brings it in line with Nuke, which also operates this way, quite successfully. Color swatches, pickers, color ramp display are now gamma corrected to display gamma so you can see what you're doing, but the numbers themselves are considered linear. This makes understanding blending modes more clear (a 0.5 value on overlay will not change the result now) as well as making color swatches act more predictably in the compositor, however bringing over color values from applications like photoshop or gimp, that operate in a gamma space, will give identical results. This commit will convert over existing files saved by earlier 2.5 versions to work generally the same, though there may be some slight differences with things like textures. Now that we're set on changing other areas of shading, this won't be too disruptive overall. I've made a diagram explaining the pipeline here: http://mke3.net/blender/devel/2.5/25_linear_workflow_pipeline.png and some docs here: http://www.blender.org/development/release-logs/blender-250/color-management/

TexFace to Material Settings big patch Summary: ======== The idea here is to move the texface options into the material panel. For images with the change please visit: http://code.blender.org/index.php/2011/09/bge-material-texface-changes 1 - Some of the legacy problems 2.49 and 2.5x has with the texface system: ========================================================================== 1.1) Shadow, Bilboard and Halo are mutual exclusive (in the code), yet you can select a face to be more than one mode. 1.2) Sort only works for blend Alpha yet it's an option regardless of the Transparency Blend you pick. 1.3) Shared doesn't affect anything in BGE. 1.4) ObColor only works for Text objects (old bitmap texts) when using Texture Face Materials. (not address yet, I so far ignored obcolor) 2 - Notes: ============ 2.1) Now "Use Face Textures" in material Option panel will work in Multitexture even if there is no texture channel. 2.2) In FaceTexture mode it will use TexFace all the time, even if you don't check the "Use Texture Face" option in the UI. It's a matter of decision, since the code for either way is there. I decided by the solution that makes the creation of a material fast - in this mode the user doesn't need to mess with textures or this "Use Texture Face" option at all. I'm not strong in my opinion here. But I think if we don't have this then what is the point of the Texture Face mode? 2.3) I kept references for tface only when we need the image, UV or the tiling setting. It should help later when/if we split the Image and UV layers from the tface struct (Campbell and Brecht proposal). 3 - Changes in a Nutshell: ========================== 3.1) "Texture Face" panel (in the Mesh/Object Data panel) no longer exists. Those settings are all part of the material properties, visible when Game Render is set. 3.2) "Texture Face" Shading mode (in the Render panel) is now called “Single Texture”, it needs a material for special settings (e.g. Billboard, Alpha Sort, …). 3.3) New options in the Material Panel * Shadeless option in the Material panel is now supported for all three Shading modes. * Physics is now toggleable, this is the old Collision option. * Two Side (on) is now called Back Culling (off). * Alpha Sort is one of the Alpha options, together (and mutually exclusive) to Alpha Blend, Alpha Clip, Add and Opaque (i.e. solid). * Shadow, Billboard and Halo are grouped in the “Face Orientation” property. * "Face Textures" and "Face Textures Alpha" (under Options) can be used for all but GLSL shading mode (to be supported in GLSL eventually). * The backend in the game engine is still the same as before. The only changes are in the interface and in the way you need to think your materials. The bottomline is: It’s no longer possible to share materials between faces that do not share the same game properties. 4 - Acknowledgment: ================== Mike Pan for the design discussions, and testing along the whole development process. Vitor Balbio for the first hands-on code with the interface changes. That helped me a lot to push me into work on that.

TexFace to Material Settings big patch Summary: ======== The idea here is to move the texface options into the material panel. For images with the change please visit: http://code.blender.org/index.php/2011/09/bge-material-texface-changes 1 - Some of the legacy problems 2.49 and 2.5x has with the texface system: ========================================================================== 1.1) Shadow, Bilboard and Halo are mutual exclusive (in the code), yet you can select a face to be more than one mode. 1.2) Sort only works for blend Alpha yet it's an option regardless of the Transparency Blend you pick. 1.3) Shared doesn't affect anything in BGE. 1.4) ObColor only works for Text objects (old bitmap texts) when using Texture Face Materials. (not address yet, I so far ignored obcolor) 2 - Notes: ============ 2.1) Now "Use Face Textures" in material Option panel will work in Multitexture even if there is no texture channel. 2.2) In FaceTexture mode it will use TexFace all the time, even if you don't check the "Use Texture Face" option in the UI. It's a matter of decision, since the code for either way is there. I decided by the solution that makes the creation of a material fast - in this mode the user doesn't need to mess with textures or this "Use Texture Face" option at all. I'm not strong in my opinion here. But I think if we don't have this then what is the point of the Texture Face mode? 2.3) I kept references for tface only when we need the image, UV or the tiling setting. It should help later when/if we split the Image and UV layers from the tface struct (Campbell and Brecht proposal). 3 - Changes in a Nutshell: ========================== 3.1) "Texture Face" panel (in the Mesh/Object Data panel) no longer exists. Those settings are all part of the material properties, visible when Game Render is set. 3.2) "Texture Face" Shading mode (in the Render panel) is now called “Single Texture”, it needs a material for special settings (e.g. Billboard, Alpha Sort, …). 3.3) New options in the Material Panel * Shadeless option in the Material panel is now supported for all three Shading modes. * Physics is now toggleable, this is the old Collision option. * Two Side (on) is now called Back Culling (off). * Alpha Sort is one of the Alpha options, together (and mutually exclusive) to Alpha Blend, Alpha Clip, Add and Opaque (i.e. solid). * Shadow, Billboard and Halo are grouped in the “Face Orientation” property. * "Face Textures" and "Face Textures Alpha" (under Options) can be used for all but GLSL shading mode (to be supported in GLSL eventually). * The backend in the game engine is still the same as before. The only changes are in the interface and in the way you need to think your materials. The bottomline is: It’s no longer possible to share materials between faces that do not share the same game properties. 4 - Acknowledgment: ================== Mike Pan for the design discussions, and testing along the whole development process. Vitor Balbio for the first hands-on code with the interface changes. That helped me a lot to push me into work on that. Benoit Bolsee and Brecht van Lommel for patch review (* no one reviewed the whole patch, or the latest iteractions, so I still hold liability for any problems).

TexFace to Material Settings big patch Summary: ======== The idea here is to move the texface options into the material panel. For images with the change please visit: http://code.blender.org/index.php/2011/09/bge-material-texface-changes 1 - Some of the legacy problems 2.49 and 2.5x has with the texface system: ========================================================================== 1.1) Shadow, Bilboard and Halo are mutual exclusive (in the code), yet you can select a face to be more than one mode. 1.2) Sort only works for blend Alpha yet it's an option regardless of the Transparency Blend you pick. 1.3) Shared doesn't affect anything in BGE. 1.4) ObColor only works for Text objects (old bitmap texts) when using Texture Face Materials. (not address yet, I so far ignored obcolor) 2 - Notes: ============ 2.1) Now "Use Face Textures" in material Option panel will work in Multitexture even if there is no texture channel. 2.2) In FaceTexture mode it will use TexFace all the time, even if you don't check the "Use Texture Face" option in the UI. It's a matter of decision, since the code for either way is there. I decided by the solution that makes the creation of a material fast - in this mode the user doesn't need to mess with textures or this "Use Texture Face" option at all. I'm not strong in my opinion here. But I think if we don't have this then what is the point of the Texture Face mode? 2.3) I kept references for tface only when we need the image, UV or the tiling setting. It should help later when/if we split the Image and UV layers from the tface struct (Campbell and Brecht proposal). 3 - Changes in a Nutshell: ========================== 3.1) "Texture Face" panel (in the Mesh/Object Data panel) no longer exists. Those settings are all part of the material properties, visible when Game Render is set. 3.2) "Texture Face" Shading mode (in the Render panel) is now called “Single Texture”, it needs a material for special settings (e.g. Billboard, Alpha Sort, …). 3.3) New options in the Material Panel * Shadeless option in the Material panel is now supported for all three Shading modes. * Physics is now toggleable, this is the old Collision option. * Two Side (on) is now called Back Culling (off). * Alpha Sort is one of the Alpha options, together (and mutually exclusive) to Alpha Blend, Alpha Clip, Add and Opaque (i.e. solid). * Shadow, Billboard and Halo are grouped in the “Face Orientation” property. * "Face Textures" and "Face Textures Alpha" (under Options) can be used for all but GLSL shading mode (to be supported in GLSL eventually). * The backend in the game engine is still the same as before. The only changes are in the interface and in the way you need to think your materials. The bottomline is: It’s no longer possible to share materials between faces that do not share the same game properties. 4 - Acknowledgment: ================== Mike Pan for the design discussions, and testing along the whole development process. Vitor Balbio for the first hands-on code with the interface changes. That helped me a lot to push me into work on that. Benoit Bolsee and Brecht van Lommel for patch review (* no one reviewed the whole patch, or the latest iteractions, so I still hold liability for any problems).

Changes to Color Management After testing and feedback, I've decided to slightly modify the way color management works internally. While the previous method worked well for rendering, was a smaller transition and had some advantages over this new method, it was a bit more ambiguous, and was making things difficult for other areas such as compositing. This implementation now considers all color data (with only a couple of exceptions such as brush colors) to be stored in linear RGB color space, rather than sRGB as previously. This brings it in line with Nuke, which also operates this way, quite successfully. Color swatches, pickers, color ramp display are now gamma corrected to display gamma so you can see what you're doing, but the numbers themselves are considered linear. This makes understanding blending modes more clear (a 0.5 value on overlay will not change the result now) as well as making color swatches act more predictably in the compositor, however bringing over color values from applications like photoshop or gimp, that operate in a gamma space, will give identical results. This commit will convert over existing files saved by earlier 2.5 versions to work generally the same, though there may be some slight differences with things like textures. Now that we're set on changing other areas of shading, this won't be too disruptive overall. I've made a diagram explaining the pipeline here: http://mke3.net/blender/devel/2.5/25_linear_workflow_pipeline.png and some docs here: http://www.blender.org/development/release-logs/blender-250/color-management/

TexFace to Material Settings big patch Summary: ======== The idea here is to move the texface options into the material panel. For images with the change please visit: http://code.blender.org/index.php/2011/09/bge-material-texface-changes 1 - Some of the legacy problems 2.49 and 2.5x has with the texface system: ========================================================================== 1.1) Shadow, Bilboard and Halo are mutual exclusive (in the code), yet you can select a face to be more than one mode. 1.2) Sort only works for blend Alpha yet it's an option regardless of the Transparency Blend you pick. 1.3) Shared doesn't affect anything in BGE. 1.4) ObColor only works for Text objects (old bitmap texts) when using Texture Face Materials. (not address yet, I so far ignored obcolor) 2 - Notes: ============ 2.1) Now "Use Face Textures" in material Option panel will work in Multitexture even if there is no texture channel. 2.2) In FaceTexture mode it will use TexFace all the time, even if you don't check the "Use Texture Face" option in the UI. It's a matter of decision, since the code for either way is there. I decided by the solution that makes the creation of a material fast - in this mode the user doesn't need to mess with textures or this "Use Texture Face" option at all. I'm not strong in my opinion here. But I think if we don't have this then what is the point of the Texture Face mode? 2.3) I kept references for tface only when we need the image, UV or the tiling setting.

(not address yet, I so far ignored obcolor) 2 - Notes: ============ 2.1) Now "Use Face Textures" in material Option panel will work in Multitexture even if there is no texture channel. 2.2) In FaceTexture mode it will use TexFace all the time, even if you don't check the "Use Texture Face" option in the UI. It's a matter of decision, since the code for either way is there. I decided by the solution that makes the creation of a material fast - in this mode the user doesn't need to mess with textures or this "Use Texture Face" option at all. I'm not strong in my opinion here. But I think if we don't have this then what is the point of the Texture Face mode? 2.3) I kept references for tface only when we need the image, UV or the tiling setting. It should help later when/if we split the Image and UV layers from the tface struct (Campbell and Brecht proposal). 3 - Changes in a Nutshell: ========================== 3.1) "Texture Face" panel (in the Mesh/Object Data panel) no longer exists. Those settings are all part of the material properties, visible when Game Render is set. 3.2) "Texture Face" Shading mode (in the Render panel) is now called “Single Texture”, it needs a material for special settings (e.g. Billboard, Alpha Sort, …). 3.3) New options in the Material Panel * Shadeless option in the Material panel is now supported for all three Shading modes. * Physics is now toggleable, this is the old Collision option. * Two Side (on) is now called Back Culling (off). * Alpha Sort is one of the Alpha options, together (and mutually exclusive) to Alpha Blend, Alpha Clip, Add and Opaque (i.e. solid). * Shadow, Billboard and Halo are grouped in the “Face Orientation” property. * "Face Textures" and "Face Textures Alpha" (under Options) can be used for all but GLSL shading mode (to be supported in GLSL eventually). * The backend in the game engine is still the same as before. The only changes are in the interface and in the way you need to think your materials. The bottomline is: It’s no longer possible to share materials between faces that do not share the same game properties. 4 - Acknowledgment: ================== Mike Pan for the design discussions, and testing along the whole development process. Vitor Balbio for the first hands-on code with the interface changes. That helped me a lot to push me into work on that. Benoit Bolsee and Brecht van Lommel for patch review (* no one reviewed the whole patch, or the latest iteractions, so I still hold liability for any problems).
