Hello, I hope you can help, I'm having trouble with polygons not displaying properly in Poser 7.  I'm creating the models in 3D Studio, exporting them as OBJ's and when I import them into Poser I get these weird shaded areas (see circled area in picture).  The model is welded quads, there are no lose vertices, I've tried turning the triangulation but nothing I do seems to correct it.  I'm going slowly mad trying to figure it out so I'm hoping smarter heads than mine can put me out of my misery :-)

I've had the same problems and haven't been able to fix them either. Do you have "Smooth Polygons" unchecked? Not in your render settings, but on the object itself?

Other than that, I have no answers for you either, but I'm wildly interested to find out if someone else does :o).

Try changing the "Crease Angle" :blink:

I've tried smoothing checked and unchecked on the obj, I've even tried removing all smoothing on the model in 3D Studio, nothing seems to change it. 

Geep, I've tried altering the crease angle as well to no avail.  Thanks for the suggestions though.

I bet it's not there when you bring it in with split vertices.

I think it's the OBJ import artifact we discussed a while back in a thread here.. I'd put a but report into SM. (please do! it's the only way to get them to fix things)

the best way to fix it atm tho is to split the vertices.....

Yep that does work Kaibach, seems like a terrible way to do it but it does seem to be the only solution!  Thanks for your help.

I don't understand why some models are fine and others are not though, there must be a technique that causes the problems in the first place?

not that we've found. it seems to be related to the UVMap information - the research done in this thread  www.renderosity.com/mod/forumpro/showthread.php shows that if you remove the UV information, you remove the artifact.

Yep I find it is always the UV mapping

Just been reading through all the threads on this, I'm amazed none of the searches I did picked them up.  Theres a lot of information to go through there, thanks for all your help guys, I appreciate it.

splitting all the vertices is sometimes overkill. You may fix the problem by cutting and pasting a few polygons without welding but it takes more trial and error.

Yes, I've found a combination of clearing the UV map initially and then splitting the remaining problem vertices works, it's not ideal but better than tearing my hair out :-)
