No, unfortunately, I don't think it's Wingss fault. The model was created in Wings, sent piece by piece to UVMapper, re-assembled in Rhino and exported as a whole to .obj via Rhino, a process I've done many times without problems. Actually, the Wings .objs always seem to be a little cleaner than the Rhino-generated ones. I have a feeling that, if I'd gone direct from Wings to UV Mapper and not to Rhino then it may have been cleaner meshes, but re-assembling various parts in Bryce is a royal pain. They're odd sizes and I can't get them back together seamlessly. Rhino imports all .objs the same size as they were originally and they are put back together after mapping without seams. Aldaron, thanks for that bit of info., but, unfortunately, these are about 1024 on the largest side. I'm thinking, though, that this seems to be an .obj problem.
