I know I read it before here on the forum, but maybe someone can help me out quicker than I can re-find it...what is usually going on when a skirt or gown heads for the floor during a clothify sim?

So far I've played with setting the collide with properties and tried various figure and object configurations and strategies  (ways of exporting objects out of poser and reimporting and clothifying the prop, etc)

I am using Angels  for Young Teens (Luke) which I think  is apparently p4/pp targeted content (dec 2004).

So far, nothing is working, and the symptom is always exactly the same no matter if it's a figure or a  prop, what body part, what setting, etc : the dumb thing keeps heading for the floor. I raised the figure (Luke) above the ground a little ways, so that the gown is well above ground. The gown collides and crumples on the body as it goes down...it's just that inconvenient going down part :)

I know it's something naive that I'm doing...I hope someone kind can point out what that is.
