i have a huge building with a lightmapped/bumped-specular material. I got 2 UV. UV1 (tilling) is for the diffuse. UV2 (unwrap) is for the lightmap. Unity automatically affect bumpmap to UV1, but i want to use it on the UV2 to draw scars on the building, how can i do this ? Does it possible to choose the uv channel for each texture of a material ?
