I made that texture by screwing with another from BioDesigner. (he makes amazing things!)
It occurred to me after seeing what Pixolicious posted that you might be having trouble
with giving your model color and materiel and stuff and not just rendering.
If that is the case I might be able to save you a lot of money and whip up another tutorial.
As I said about rendering I do not fully understand it, and the same applies to texturing
and painting stuff in ZBrush but understanding it is less important then being able to do
it, and that is something I can do.
I like making tutorials, making them helps me too and gives me new ideas about how to do things.
