It's a stand alone.  You may import .OBJ, bend the strings around any objects you can dream of, and then export the finished string.  The strings easily import back into Poser.

I can't remember how UV mapping work, but I use UVMapper anyway.  It was neat little program it just doesn't want to work in the new Windows.  Even tried it under both XP Pro and Business modes.

The video on the site pretty much says it all.  You can be bending strings in no time at all. -R
