Oh wow, UV Mapper is extremely confusing!! I loaded the OBJ file into UV Mapper, then hit the Split Vertices option. When I loaded the new OBJ into Poser, I noticed that a lot of the geometry was very blocky and pixelated, and the stretching problem still wasn't solved. Did I do something wrong? Also, I noticed that UV Mapper has options for importing and exporting UVs. Is there possibly a way to export just the UVs from Max, import them into UV Mapper and the OBJ model, then voila problem solved? Yeah probably not but we're getting there at least. Thanks for the help so far. I'm confident that the problem will be solved soon.
