Ik
Reaches a chain of bones toward another node: an arm's hand, a leg's foot. Goes on the chain's tip; lower its weight to blend the reach with the animation. A chain of one bone points instead: a head that watches, a turret.

From a script
A script on the same node writes these fields by name. IkComponent is the name to pass.
