What's the meaning of AA All Controls Node?

Hi,

I walked around but find the answer about the " AA All Controls " node in the physics control level in the official Content Example project.

and I want to know where the shake animation comes from, anim sequence or anim BP?
I can’t find the shake animation either.

Does anyone help thanks! thanks!


also curious after watching this persons walkthrough of the physics control content examples. Cant seem to find what “AA” means
