I’m really wondering if I can overlap maps in uv channels that are not being used for lightmaps? I want/need to be able to overlap maps like the diffuse, and normal maps etc.
Also, I have one more question: When I am unwrapping the light map channels and I have two different props where one has more surface space than the other. Do both of those prop’s lightmap uv channels need to be scaled the same? Like what if one prop is 100x bigger than another. When I unwrap the lightmap uv channel of the smaller one will it need to be scaled really small?
