adp, I'm still having some issues with exporting and importing some figures but I think I've found out why. some of the figures I've tried to use it with have UNWELDED groups, and at some point in the export, modeler, import process it appears that the groups have been welded. At least the difference in numbers of verts match up with the number that welding the verts in UVMapper pro. It may be the modelers I have doing this since my options are limited ( and this included loading the obj into Blender and re exporting it to load into Poser using your script. I haven't learned enough about Blender to prevent this YET. But I just wanted to let you know about this incase it happens to someone else.

BTW on some figure with welded obj this seems to work very good. At least when exporting and importing the same OBJ, which is as far as I've had time to try so far
