You need "shaper" its a free obj tool basicly it welds what ever body parts you need into one, you import this obj to your modeling program morph it to death, then shaper takes apart the parts back to the org. so you can bring it back into poser.

you need to e-mail the owner to get this special function to work, its great and its free
