OT but responding to hdaggers, I use P5 (lately, P6) as a cloth engine in conjunction with a Carrara modeling workflow. Downside; gravity can not be turned off in the Poserverse, and cloth thickness (for self-collision) is not set-able. Upsides; cloth is fairly fast, and clothification preserves groups, texture domains, and UVmapping. The latter is a boon for getting a clean UV map of a draped object like a tablecloth or full skirt.
