Dynamic Joint Chain: With the last of the extra joint options, you can create a joint chain with however many joints you would like. The joint chain will be rigged with an FK setup, a Spline IK setup, and a physics rig using hair follicles. When you add a dynamic joint chain, you will need to specify the base name (for instance, ponytail), the parent of the root joint of the chain, and how many joints are in the chain.
