Thank you sir very much.
It did really work.
I just have to refine it so the head don’t go out of the body.
While looking at the Face_AnimBP of the metahuman, i found out that those nodes do exist but they are connected with different nodes (see pic), so my question is why those nodes don’t have that effect of syncing the body with the head?
Edit:
Editing to mark that the syncing is accomplished without connecting the output node to the layered blend per bone node, because if i connect it the animation is not playing right by syncing the head with the body, in another word the head will be floating outside the body, is this correct?
What i did is just disconnect the output pose node.
