gri, thanks for the insights, but I don't understand the second point.
Can't you play the walkcycle and ent_bone_rotate the head right after that?

In case that isn't possible, one could add a bone animation to the model with the head rotating and set its animation depending the position of the target at which the head shall look, right?
