I finally had time to test drive Glitterati3D's wonderful multipurpose gown (MPG). I found that if I copied the V4 MFD morphs to it (they generally play well the mesh), I got something close to the degree of control over skirt movement that the PE beta mannequin morph provides. The big advantage is that it is truly native to La Femme (LF). Let's say LF wants to sit with her legs crossed. I could not get the stock dress to completely work with the pose, but with the MFD morphs, I had a lot of options to play with. Here are the results.

I'll try reconverting some gowns using MPG with MFD morphs as the donor.
