Attached Link: edit dynamic group: the selected vertices will highlight red

If you have parts such as a belt, buttons, and pockets which were modeled as separate pieces, you can *edit constrained group* to make them follow the underlying doll.  Pockets may alternatively be assigned as *soft decorations*, whereas buttons and a badge might be assigned as *rigid decorations*.

I don't see a way to link a second image, much less be able to post a clickable thumbnail, so here is the address of a screenshot showing the constrained group being edited, using the same dress.

  All the vertices in this dress are either in the dynamic group or the constrained group;  it doesn't have any soft decorations, rigid decorations, or choreographed parts.

If you see an "icicle" growing during a dynamic simulation, check for an errant vertex, such as one vertex assigned to choreographed which should have been assigned to dynamic.

TrekkieGrrrl, for the issue of a hem -which will need to be in the dynamic group- I have an idea which may (or may not) work.  Try loading the obj into a modeler and merge all the groups.  Then, use bridge to connect polys of the hem to the polys of the bottom edge of the dress.  Basically you want to form a contiguous ball-chain web.
