My MetaHuman needs to look around with his headset, then take it off. This requires the SM_Headset to be initially attached to the head bone. After a certain time, SM_Headset’s parent must change to a hand bone.
I can achieve this by exporting my MetaHuman to a 3D package, animating it there, and then importing the animation back. However, I am trying to become accustomed to animating inside Unreal Sequencer.
