Thanks guys. I actually took this over to the Sculptris forums. The current Sculptris release has difficulties if too many lines are intersecting at one vertice. The horns on my bull head were what was killing it.

Also, I had meshsmoothed the the model to death and I think the heavy polys didn't translate well. I found a really good tutorial for reducing polys at www.shapeways.com/blog/archives/226-Polygon-count-reduction-with-MeshLab.html

Using the freeware Meshlab (so powerful, so free!).

I'm going to bookmark your site, Bob and also try the UV unwrap tactic you mentioned. =)
