Mecanim - controlling head position/rotation using IK?

Hi,

I really need the ability to set my character’s head position and rotation using IK, however I cannot find out how to do this. The Animator script reference is no help either. AvatarIKGoal does not contain a property for the head, which means I cannot simply set it using the SetIKPosition() and SetIKRotation().

Can I do anything about this? Or is it impossible unless Unity adds that feature?

SetLookAtPosition

It’s Like IK but controlls the head I guess it should be in OnAnimatorIK function
