I am using 3Dsmax8
I have a question which hopefully someone out there has a solution for. I have been working on an environment and have been utilizing face mapping techniques for UV mapping the texture, meaning UV's are overlapping for different parts of the environment faces. Now the trick has come and I have been asked to apply a shadow map to the environment. Unfortunately using the "use existing map channel" in render to texture is not going to help me because UV's are overlapping and would cause artifacts. The current workaround I have found is to apply an automatic unwrap just for shadow baking purposes and then input that new map into the self illumination slot of the texture and have it use the second channel. Basically applying two textures to the same mesh using two seperate UV channels. Automatic unwrap is hideous though, completely disgusting as it breaks the entire mesh into tiny fragments, thus resulting in UV's which produce both crap shadows and at different resolutions and being basically useless, but its the only way I know of.
Apparently face mapping is the hot thing to do these days and more places are using it but I'm left scratching my head when it comes to baking shadows and using render to texture for anything using this technique. Any ideas, suggestions, shared frustrations?
