The method posted here still works to an extent, you have to use an Optitex outfit to trigger the drape in anything using the method posted in this thread, grab the free bikini from their site, load the bottoms and set it to collide only with the figure, set the opacity on it's surfaces to 0% to hide it, and then set the dynamic control to drape "all cloth in scene".

bet Bruce is off running to Rob to report that one lol
