Start with a newtrual grey page, and the white sticks out, the black dents in, the rest follows the same concept as a trans map, I'd be happy to give you the one I use , but it's for 3ds max, and requiers tiling. That's about all I know, I'm not to wellversed in them either, I just experimented with Painter 3D and got lucky. -Hope that helps, -Gabe-
