for lightmapping from an external program where the objects texture is on one set of uvs(with tiling) and the lighting id baked done to its own texture and placed opn a different set of uvs (non tile)
thanks for your help

You can do multiple layers of textures on one object like this. You can not at the moment have a object that have has layered materials (every material has it’s own set of uv’s). All textures must share the materials UV cords.

How ever, if your using maya you can set different materials per object, and for each material another set of uv’s. Then I think (some one correct me if im wrong) you can add another layer to all of those materials (this will be your light map layer) and then bake your lightmap into that layer. So each set of material’s has uv cords with a tiled color texture and a peice of the lightmap.

I have not tried that but I will soon, I have a space station that will require multiple materials and in each material multiple textures including maybe a lightmap texture. Both of these methods will require a special shader made. I think what ill do is bake the light map onto the texture eliminating the need for multiple textures. There might be another way to do this and I might have over looked some thing so correct me if I have. Also other programs might be able to do this, but I know for sure that unity will import multiple materials from maya no prob. Hope that helps

Multiple materials can be imported from C4D also. Jeff

And from XSI too on PC FYI. Multiple materials each with their own UVs.
