I don't use clothing programs because I don't use human figures. I use my own models in Poser. From what I can tell from the conversations is that WW just uses technology already existing inside Poser. The fact that the figures have to be hard coded into the program leads me to believe that for the JP part of the conversion. The script goes through the base model's .cr2 file and logs the start point,end point, and handle locations of each body part's JP. Then loads those settings into the clothing being converted. As far as the morph transferring goes. That one I'm not so clear on. But I would imagine it's something similar to the JP transfer. Only using the geometries point locations inside the .obj files. Just guessing. It's a clever twist to the cut and paste operation. You can do the same thing by hand if you're a nerd like me ;-). But they packaged it in a way that's quick and easy to use for the less techy types. And I like that. I've always been a fan of getting results first. Then go back (if you feel like it) and learn why things work. Not the other way around. -ScottA
