Thank you very much for this tutorial! I needed the solution for the weird leg movements when using the crouch animations, and simply disconnecting the control rig node in the Animation BP did the trick!
I was wondering if there is a solution for this problem that involves corrections in CR_Mannequin_BasicFootIK rather than just disconnecting it altogether. Do you happen to have more information regarding this?
I don’t really understand what this does, but it works to solve the issue with the feet without having to completely disconnect the Control Rig node from the Anim BP of Manny/Quinn. I hope this helps!
