Yikkes! This thing is over 5meg. I'm afraid I can't handle files that big. Nor can I upload files of that size. I can tell you what the problem is though: Your .obj file does not have any groups. Only materials. It's one single mesh with multiple materials. You can try exporting props again. Or use UVmapper and select each material one by one. And assign a group to them. Then try PHI Builder again. I'm afraid my equipment is way too crappy to handle a file this big. ScottA
