That's curious. Of course I had to have a look at Vivian's Hunter model straight away:) and when I loaded it into AC3D (V3.6) I found no real problems with it - very nice indeed:) There were a couple of redundant vertices (easily missed) and a couple of polys that were being triangulated less than optimally but the model looks fine in FG on my system - neither the two extra vertices or the triangulation problems were apparent at all. I can't see anything obvious in AC3D that might be causing what's in that screen grab. I can't remember what package Vivian used to create it - Blender or AC3D - Vivian?
