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.
Texture matrix bug in plugin code reported by Mel_Q.
Vertex colors, this was basically the same as the previous uv coord
splitting bug, for xml export, uv coord splitting was actually not quite
complete either (reported by richie).
Added:
Camera Ipo curves for DoF aperture and focal distance.
Aspect ratio set with AspX & AspY are now taken into account as well.
(needs yafray from cvs)
Bokeh parameters for DoF (also needs yafray from cvs).
'Bokeh' controls the shape of out of focus points when rendering
with depth of field enabled.
This is mostly visible on very out of focus highlights in the image.
There are currently seven types to choose from.:
'Disk1' is the default, the same as was used before.
'Disk2' is similar, but allows you to modify the shape further with the 'bias'
parameter, see below.
Triangle/Square/Pentagon/Hexagon, in addition to the bias control, you can
offset the rotation with the 'Rotation' parameter (in degrees).
'Ring', a weird ring shaped lens, no additional controls.
The 'bias' menu controls accentuation of the shape.
Three types available, uniform, center or edge, with uniform the default.
Although based on an actual phenomenon of real camera's, the current
code is bit of a hack and not physically based, and doesn't work all that
well yet (in yafray anyway). Since this is also mostly visible in the very
out of focus parts of the image, it usually also means that you need lots
of samples to get a reasonably smooth result.
Blender hemilight shadow flag now ignored (reported by varuag).
Texture axes were not exported for procedural textures.
Duplicate armatures were not handled correctly (reported by richie).
Triangle uv-coord splitting (reported by anael, richie & Alvaro).
Additions:
Material 'TexFace' mode now works too, as in Blender it functions as an extra
first texture channel, replacing the base color.
The new noise functions for procedural textures are now supported in yafray,
but is not quite completed yet, still undergoing changes.
(needs yafray from cvs).
The 'power' button has been renamed to 'EmitPwr', since it controls background,
arealight (including lamp with radius) & material emit power.
This button can now be used with the 'SkyDome' method as well to control
background lighting.
To control indirect lighting power, a button called 'GI pwr' has been added,
only use this when really necessary, first try modifying 'EmitPwr' instead.
Removed:
The 'gradient' button. This includes the python code to set
this parameter as well.
When using xml export, yafray will now render the alpha channel as well when 'RGBA' button in blender is enabled (Plugin does this automatically).
In plugin code, fixed smooth shading bug for non-mesh objects.
Relative paths for textures are now recognized (plugin & xml).
Fixed problem with duplicate objects (plugin & xml).
Really old bug, sun position is now correct (plugin & xml).
World background now can also be a regular image texture (jpeg & tga), but for now always assumes spheremapping, which is not the same as Blender either. In yafray the texture is assumed to be a full 360 (panorama type) map.
convertBlenderScene.c cleanup, the identity transform 'hack' is removed.
THIS AFFECTS ALL EXTERNAL RENDERERS (Aqsis and others) WHICH RELY ON THE RENDERDATA OUTPUT, VERTICES AND LAMPCOORDINATES/VECTORS NOW NEED TO BE TRANSFORMED BACK TO WORLD COORDINATES. See yafray plugin/export code.
Just making sure memory is always allocated and freed in the same
binary object, which seems to be mandatory on msvc if you don't have
the comercial version. If you are using this code you need to
syncronize with yafray cvs also, or it won't work. Binaries for os x
are updated in the link I gave in my last commit.
Needs latest yafray, you can get it from cvs, but I have also binaries
for os x here:
http://www.coala.uniovi.es/~jandro/noname/downloads/yafray-0.0.6-3.pkg.zip
To use it, go to yafray panels (global settings) and uncheck the "xml" button.
That would tell the export code to avoid xml export and use the yafray plugin
instead. You'll see the render being draw while running and you can even stop it
with ESC key.
Since I'm sure problems will appear, expect updates soon.
Remember: does not work on win32
