Smoothing off.  I've tried to avoid having to split verts on all those little detail parts in 72 groups, though at the same time keeping it low-poly enough for fast animation.  It's looking like I might have to smooth it though (lots of extra work, but a better result.)

Are you rendering with displacvement ON in render settings and the bumpmap node connected to displacement in the shader?  If so I wonder if maybe I've changed something in my P7 installation that would cause it.

I've sent it to a few others too so if we can all post findings here int his thread it can help everyone.
