>>2754553That doesn't clarify a whole lot. If you want them to be movable by applying force to a single specific starting (vertical) line, this can be achieved by sequentially linking the bones perpendicularly to the starting line through the append parent property with the move flag enabled. If you want them all to be affected regardless of the point, then that cannot be done. Otherwise, if you want only the rigids that contact an external object to be moved, no action is needed other than putting all skirt rigids in the same group and ensuring all of them can collide with groups that should be able to move them. And, of course, using an object of required size to come in touch with the rigids you need. If necessary, see the part about closing the gaps. You may also want to increase friction of the skirt rigids, but this comes with its own disadvantages.
