IK system, activation on animnotify or automated?

Hi all,

I’m currently working on the IK system for our game and have a solid system running. However, I’m wondering what the best option is for activating it.

  1. using anim notifications to activate and de-activate it?
  2. Using an automated system that scans the distance between floor and ik bone. (How would you go about the lift off?)
  3. something else?
