Exploring the Duik Rig
This tutorial is a follow-up to Auto-Rigging with Duik. It focuses on the puppet controls that were added when the Duik script auto-rigged Stickman. This video may move a little slow for an experienced After Effects user, but you still may find it faster than trying to figure out what each Duik control does by exploring it on your own.
You can explore all of the controls that Duik placed in your puppet when you auto-rigged it yourself, or you may want a walk-through first. If so, this video focuses on all of the puppet controls that were added by Duik. This is an informational video, and you do not need After Effects up and running to learn from it.
