Just for fun I loaded the Steph petite obj into Hexagon and played around a little bit. I saved the obj out (just the head actually) and imported as a morph target in Poser. Nothing I'd actually want to use; it was just a test to see if it would even work without tweaking. It worked OK, although I couldn't figure out how to do changes symmetrically. Well, short of cutting the mesh in half and using Hex's symmetry tool anyway. Wasn't sure if that would mess anything up so I didn't try it.
