I've decided to start this thread to share the scenes that I've been using to test and modify the Yafaray4ts scripts. The scenes were imported in collada format and then the material settings and render settings were copied from the original Blender scenes. The user guide pdf and Blender scenes can be downloaded from the top of this page: http://www.yafaray.org/documentation/userguide"
Do NOT press the save settings button in these scenes. That would overwrite the Yafaray4tS that is installed. If you do press it just use the installation scene included with Yafaray4ts to restore it back to the original.
Now to the first scene. This is the glass scene. It's the first test case I tried and it helped to identify a normals bug in the scripts.
This is the glossyasdiffuse scene. This one showed me the need for a global input gamma value for a scene. Plain colors without gamma were rendering as washed out and desaturated until a gamma was applied to them. It also showed that the Yafaray area light was not centered properly when it's position was set to the origin. I modified the shape of the area light to center it on the origin and added code to give the option of making the light visible in the render output.
This is the maxk3duchnia scene. This scene is my first scene with a texture map. I changed how some of the gamma is handled. Changing the gamma of a texture changed it in the 3d view in truespace, taking it further away from matching the final rendered result. I removed all influence of gamma on textures for display in truespace. The default gamma for textures was set to zero. when gamma is zero then the gamma value will be read from the global gamma in value. Any value not zero will override the global setting. The purpose of the "gamma in" on the render settings(or the gamma value on the texture if it overrides this value) is to convert all colors and textures to linear values, which is what the render engine is using. The gamma out is used to convert back to a useful non-linear space so we can see the image properly.
Here is one of the best explanations I've heard of gamma and color space:

The glass material was too transparent in the 3d view so I exported an alpha control in the glass shader to get some control over the transparency. This is the first scene to not have any new code added to the Yafaray4ts scripts. I did notice that the yafaray sphere light has the option of being visible in the render, but I'll save that for later. This scene also has a short script I use to convert from blender color values 0-1 to truepsace range of 0-255
Caustics scene.
Found a bug with this one. Caustics was not working with Direct Lighting. Looks like you have to specifically tell the output file that caustics are being used. As far as I can tell the other lighting methods don't need it. They just know when you're using caustics.
EmitPT scene. No bugs found. This one takes a while to render. The original Blender scene had 100 AA passes. I reduced it to 10 and ran the same 10 passes in truespace for comparison. The blocks are emptys from the Blender file converted to cubes in truespace. They should have been removed or made invisible for the render.
That's a BETA so it may be buggy and posts say that it's slower than version 0.1.1. It adds volumetrics to the xml renderer and support for more file formats besides just tga and exr.
