how does that work? would you write a playmaker script testing your distance to the npc each frame, and if you get within a certain distance, you set the ik target of the head to the main camera by using a set property action, with some 'reaction speed' variable?
and is there a way, by chance, to save and playback custom manipulations as animations? like, you hit play, do some stuff, and it saves it?
and am i right in thinking this would make it easy to use blender to create a custom hand rig (for vr) and allow the hands to grip different objects uniquely using different ik targets for the joints and fingers?
