Kinematics: Faking

• Faking: Translate between kinematic systems

  • No rig has the right controls for every behaviour
  • So:copy complex behaviour onto the controls you do have

• Method:

  • Duplicate the control you want to drive
    • Same space, pivots, and local rotations
  • Parent constrain the duplicate to the source
  • Bake the constraint
  • Copy baked fCurves to the original control
    • This is brittle, like all baking
  • Delete duplicate

• Uses:

  • Adapt mocap to a hand-animation rig
  • Fake a temporary attachment w/o constraint
  • Translate positions between spaces

• UI:

  • Fast hotkey-based method removes most drawbacks
  • Smart key-ranges help a lot
