sorry joined discussion a bit  late, but I have the same problem with clothing in the cloth room.  have 20 frames to drape material,  have a simple walk pattern created with poser.  figure starts  out fine,  about frame 45 the clothing goes every which way,  in all my other posers had no real problem in cloth room.  If you reset simulation, the cloth will not return to normal shape or zero position so it has to be deleted and re-imported.

The ones that I give life, are not those I see
