A while back I tried to write a script for loading HD morphs into Poser from .obj files but gave up because there were some oddities with how higher subd-level deltas are interpreted along UV seams that I couldn't make sense of. Not sure if Poser 13 has added the ability to load HD morphs not made in Poser, does anyone know? I've also had some weird issues with morphs created directly in Poser wiggling all over the place when the figure was posed. So personally, I decided to wait for full unimesh support and then check if I can make sense of the available documentation (if any) before trying anything with HD morphs again.
