So I need my particles collide with about a couple hundred poly objects that are all animating independently. I could assign them one by one, but then editing the values would be a nightmare. Maya doesn't seem to allow you to link a hierarchy as a collider. Does anyone know of a work-around for this? I was looking into some way to combine all of the objects into one and bake the animation to be vertex based. However, I can't seem to find a way to do this. Anyone? Thanks all. -dann
