Hi Reddog9, I've got PT2 working pretty good for importing characters (PCI) the only thing I'm really not happy with mesh weighting. The prop importer (PPI) is ok. They both do a fair job loading morphs, materials, and armatures. I haven't really looked at exporting to Poser. One big structural change I made was to start moving functionality into libraries. Texture/Material loading for both PCI and PPI are handled by the same code now, and I want to move the OBJ loader into a library as well. The Poser Tools obj loader works a lot better than the Blender built-in obj loader and a standalone obj loader would be useful. Having the the mesh code split out will make it easier to support multiple meshes in a single object as well.

There have been a lot of Python API changes in Blender, I'm still working with 2.9.x I haven't looked into 3.0 yet.
