Briefly about your MD garments: I used Blender's "Tris To Quad" feature. Poser seems pretty happy with it (only tried two pieces though).

What is definitely needed are maps for the different areas. I've had very good experiences in the past with seams being at least marked as less stretchy, and a bit more sticky if necessary.

I had once started to make a script that assigns marked areas from image files to cloth parameters (UV map). This works, but would need an appropriate user interface for the normal user. And that's a lot of stupid typing just to get some widgets on the screen - I don't really like that much; although - or just because - I know wxPython inside out :)

Last point: "bodice-dress.obj" has no content (0 vertices)
