While cheching the texture map for stretching, I noticed this black area in Poser. Any idea what it is? And can it be fixed in UVmappwer? I would hate to have to fix it in Rhino after creating the texture map :( Thanks smerc

I'm not positive.. but it looks like reversed normals? in other words the polys are pointing inside instead of out...

Try fix seams with UV mapper, maybe it will solve the problem.

I tried using the fix seams option in UV mapper and it made things worse. It rounded out my sharp edges. I tried "insert", fix degenerate facets, and it helped with the left problem area, but not the center area (9 degenerate facets found) Can I flip polys in Poser using the grouping tool?? smerc

uvmapper should also have a 'check for degenerate faces' function as well. That is what you are looking at. Davo

I've had cases where the only way I could fix it was to cut out the bad section, then either reconstruct the mesh or more often weld in a clone from another, good part of the model. If UV Mapper finds the mesh too degenerated it will often just crash, at least it does for me. Maybe my models are just too degenerated though- might have something to do with 6" high heels! ;-)

Hi Jim - I can take a look at the model if you'd like. I have written a couple of new facet tools for UVMapper Pro and would love to try them out on your model. I promise not to use the model for anything other than helping you. If not, no problem... Steve stevecox@optonline.net

Hi Steve!- Gee, they all have been fixed, and I didn't keep a copy of the bad stuff (actually I'm real careful about deleting the bad stuff, otherwise sometimes the bad parts acidently get reused) but how about the next time I run into this I'll send you a copy of the OBJ?

That sounds good - thanks =) Steve
