And I apologize if this has been discussed in depth elsewhere; this forum is terrible for searching on anything productively.

I'm building a model vehicle in Lightwave that I want to convert to a Poser character. I have the book on Poser 4 Pro Pack, and I've read the tutorials on creating characters and adding joints, but I don't recall seeing anything that deals with mechanical joints; I don't want the metal joints to bend, I want them to pivot. Is this difficult to set up? Is there any special prep work I need to do to the file before exporting the OBJ and importing it into Poser? I've already imported the static model, which looked much better than I'd even hoped, but I'm not quite at the point where I can make doors open and close, flaps pivot, etc. Should I import parts that move against one another as separate OBJ files, or simply make sure that the vertices between them aren't welded?

Inquiring mimes want to know :-)

Thanks!
