Quote - If you make a displacement map for his face with zbrush, my shader will use it. That way you can cut those creases really detailed instead of trying to force the geometry to go that way.

It's funny you should say that because I was just thinking and wondering if a displacement map might work. However I have no experience with displacement maps whatsoever, especially in ZBrush. I'm mostly experienced with just morphing in there. Could you point me in the right direction to learn more about it or put up a brief summary on how to do that?
