I've tried clothifying in Poser 8, and it works to a very small degree. Of course, the more frames you run the sim in, the worse it looks, and it's very difficult to simulate real flesh effects.

I think you can import the model into Blender, but not the rigging. Blender has material nodes too, so you may be able to import those. I haven't tried it because I am still trying to figure out how to delete the default cube (kidding, I can do that, just not much more). But I've watched a ton of tutorials on Blender cookie and Blender guru, and I've seen almost every aspect of Blender's capabilities. Now if I could do everything I've seen, I'd be dangerous.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
