I am getting strange spikes in the sleeves of a conforming bodysuit that I made for V4.  I imported the cloth into Poser as an obj file (modeled in Carrara).  I entered the Poser 9 setup room.  I went to the library and loaded the bones from the V4 developers pack from OKC (bodysuit no fingers).  I let the autogroup do the grouping.  I exited the setup room.  In general, it is OK, but I am getting some strange artifacts in the sleeves when I bend the arms.  I've attached a picture of the spiky arms.  I'll post a picture of the mesh in a reply.

 

Should I be focusing on the model in the 3rd party program?  Should I be focusing on the Poser 9 setup room?  Should I focus on the grouping?  Is it a joint editor issue?
