i've modelled a long skirt in hexagon 2.1, used Markdc's autogroup to get the groups.. then use p-wizard to get the clothes in poser... however i seem to have a weld/group probelm.. my skirt is on the left... i want to make it look like the one on the right... please can you help thank you... Mike

The problem is in the buttocks. This short skirt should have all geometry assigned to the hip (and maybe abdomen). Thatl'll give you smoother deformations.
If you want longer skirts to behave, you have two options.

1. Dynamic or conforming/dynamic hybrid. Dynamic parts work very well for skirts.
2. Don't use the buttocks/thighs/shins. Instead, create "rings" of polygons and create a chain of bones originating from the hip, going straight down, matching the "rings".
   This kind of skirt does not automatically fit the legs, but is fairly easy to pose.
