Once you get to a clothing mesh in that can be imported. The next challenge will be defining the body part groups. There are tool in Poser that will attempt to do that for you. None produce truly acceptable results. There's an extremely important rule that the automatic stuff doesn't necessarily stick to. The polygon groups can only touch parent to child. Sibling parts can't touch, grand parents can't touch. I'm working up a tutorial on that right now.

There's also a kind of "My first Poser figure" step-by-step here: https://www.renderosity.com/forums/comments/4489210/permalink
