Er… I… I am honestly not quite sure if I am the idiot here or if this request is really stupid. The IK bones in the Epic skeleton are meant to be placed via BP so you can then drive the FK bones and align them to that, yes? Like, move the IK bone to the location of the door knob so that the door opening animation grabs the door knob properly? This means that not only would there be no need to animate them, you musn’t animate them so that the animation doesn’t screw with your manual placement.
Perhaps I am misunderstanding something here but if what I wrote is true then the request is an inane as it gets.
