I never split my body groups. In Lightwave you can export the body group objs without doing this. And with Greenbriar all the morphs are exported in one shot. This is one of the major annoyances of Poser from one version to the next you can't trust things will look the same.

I think the problem is caused by a new feature of P6--Smoothing Groups.
The P6 manual discusses these. They're not required, but if they exist P6 respects them.
The geometry of the Jessi Pink Bra has embedded smoothing groups. If I create a prop at the offending areas and export as an obj, the obj keeps the smoothing groups. P5 seems to ignore them and renders without artifacts. If I then export from P5 as an obj, there are no smoothing groups. So, re-importing the P5-created obj into P6 renders OK because there are no smoothing groups.
Also, after editing out the smoothing groups from an obj exported from P6 leaving everything else the same, P6 renders without artifacts. The smoothing groups of the pink bra cause artifacts at the odd triangulated facets, AND at the interface between body parts. I don't think (but I really don't know enough) that smoothing groups can span body parts.
We need to learn more about the proper application of smoothing groups.
Jim, you're right.
While removing the smoothing groups did remove the P6 rendering artifacts at the triangulated facet, it did not help at the interface between body parts. These would appear to be two different problems. I focused on the triangulated facet and was wrong to assume the fix would apply to both.
I'm not sure that any program should automatically, physically weld body part seams. That changes the geometry and would screw up morph targets. I don't think P5 does this. I do think that P5 is more forgiving than P6, applying some sort of smoothing that I can't turn off. Perhaps P6 has to do things differently, more strictly, to allow the new crease angle feature, or perhaps it is a bug.

Oh, all versions of Poser do the welding, there is a command in the CR2 that tells Poser to do it, if you leave it out (I've done that!) you get exactly this result, the welding isn't automatic. In fact, when I saw the problem that is the first thing I checked. ;-) Here is what it looks like in the CR2 of my swimsuit: weld abdomen:2 hip:2 weld chest:2 abdomen:2 weld rThigh:2 hip:2 weld lThigh:2 hip:2 I did some rendering in Poser 6 today and noticed some other bugs too, like the metal "gold" shaders aren't working right, I also noticed the area render was coming out black if you used ray-tracing, but that was before I put in SR1, I didn't check it after. The more I look the more bugs I find.
