YafaRay UV Cube XML Code

[oort]

I finally figured out the YafaRay.xml code needed to get image textures to render correctly. The only part that I had wrong was the uv vector values as in <uv u="0.0" v="0.0"/>. After looking at the code exported from the Sketchup YafaRay plug-in I noticed that the code didn't have to be as complicated as the .xml code produced by Blender. I also noticed that it looked very much like the code exported by the Wings3D Pov-Ray plug-in. I wonder if the YafaRay.xml code is based on Pov-Ray??? The code needed for YafaRay is different in the "vertex vectors" section compared to Pov-Ray. If I am not mistaken the uv indices are simply references to the uv vector values??? Below is the code for the mesh section of the .xml code.

Edit: In the code below you will notice that the material is listed once. You can also list the material before each individual face. I am listing the material multiple times in the current version of the Wings3D YafaRay plug-in. Since it works, I will leave it that way for now.

This may not be specific to programming for Wings3D but it may help someone else in the future.
