Hi
I've managed to export my models for FPSC but there something I would like to understand.

Let's say that I have car model with 3 textures assigned to it and it works just fine when put to FPSC. And thats when my question appears.

For example if I want to make specular map for every of textures (car elements). Do I have to UV Unwrap them or I can just copy each of diffuse textures and make from them specular maps with proper name.

I hope you can understand what I've meant. Sorry I'm not native english speaker.

Anyway... Do I have to UVUnwrap every texture (diffuse and specular) in blender and then export it to .X file or I can just UVUnwrap the diffuse one and spec map will be applied automatically when I use FX?
