How can I retarget an animation with some hair joint in it?

The default humanoid rig doesn’t have any hair joints, and I can’t create a new rig from skeleton in 4.16, is there any other way? Thank you.

You can add a head bone to the hair rig and then use copy pose from mesh to attach the hair rig to the character rig.

Hi, cyaoeu, I will try that, thank you!
