Thanks bwtr,
I've done some of that and it does work well with the slightly bigger details but with the finer details I think I'd have to add geometry for it to work well. I was hoping to use maps for some of this. I'm kinda new at trying this so I appreciate all the info I can get.
Odd I can get it to add this detail in Poser using only a map in the desplacement node, but not yet in Carrara (which I love to work with!).
