Okay, one other question; what is the best way to do bump-mapping on a character? I think I investigated before attempting to get a normal-mapping style effect on a skin and didn't have much luck; is there any recommended way to make a surface on a skin look "bumpy" even when light is applied to it?
I don't require proper bump-mapping; as I understand it this is only really possible on map surfaces and even then isn't perfect; however, I'd like to create an effect as close as possible.
