Hi Matt, and thanks. For this image all I used was one sun light and AO. I used the light rig in my first image (on the first page of this thread) without the AO. I decided to see how much more detail I would get from 1 patch to 200. If you look at the first image (the one at the top of the thread), you'll see I get alot. And 200 patches isn't alot either. Especially when I get detail like this from a displacement map that really isn't as detailed, or good, as it could be.
Thanks again .
