I'm trying to export a Mercy UV Texture (for use in Tabletop Simulator :P) but I've been struggling a bit. As you can see here, the textures are positioned / look like they are working correctly before I begin the UV unwrap, however after unwrapping the texture begins to act a bit weird.
It seems that the UV Map is just overlaying one of the textures on top of the whole map, rather than assigning each texture to each island (I'm sorry if my terminology isn't quite right), as shown here.
So my question is how do I properly assign textures to each part of the UV map? I read online somewhere that placing each texture into the correct island manually is an option, however given the hundreds of islands this isn't practicable at all for me. Considering that the model and textures look fine before UV Mapping, I'm assuming that there is a much easier way to do this, and that I am missing a setting somewhere?
Any help would be greatly appreciated, thanks!
