I remember seeing somewhere how a simple skirt was rigged in Maya using curves that were converted to a dynamic hair system, which in turn deformed the geometry. I have gotten that far, but I also remember the guy who showed it to me was able to drag a ball around the screen and the skirt collided with it realistically in real time, without having to hit play in the timeline. I can't figure out how to reproduce this.
My intentions are to use this method to rig a similar skirt for a female character, where it will collide with the character's legs in realtime, while the character is being animated.
Is this even possible, or should I just hide the skirt geometry until I finish animating the character, and then worry about the skirt moving later?
Does anyone know how to do this? Any help would be appreciated.
