I have no doubt that I am the umpteenth person to ask about this, but I want to learn and focus on where to look for the root causes of problems, rather than trying things at random and becoming discouraged. The space suit pictured is a fairly simple model (mostly boolean shapes) done in Max 6. I imported and converted it with Poser 5 to a .obj file. I followed the nice tut on Poser's website about basic bone and setup, with OK results- my model can move! But, of course you see the prob, and one that I'm sure everyone starts with. I've looked through the archived messages here, and found some interesting things. Is this a problem with the way I modeled (polygon count/ vertices/ welding)? Or can I overcome this in Poser itself. I did work with the grouping tool with mixed results. I appreciate your time and comments. Paul
