UE5.6 Head Movement IK problems.

I generated an animation sequece for my metahuman face by an audio file with head movement enabled.

When I use it in my metahuman the neck will be distorted if the “Enable Head Movement IK” is enabled in “ABP_Face_PostProcess”. If it was disabled, the neck will be OK, but no neck movement from the generated face animation at all.

How can I join the generated face animation with neck movement to the body?

This is “Enable Head Movement IK” is enabled in “ABP_Face_PostProcess”.

“Enable Head Movement IK” is disabled in “ABP_Face_PostProcess”.

you could take a reference from this tutorial :
