Match Frame

For the purposes of combining inverse kinematic (IK) and forward kinematic (FK) animation, this is a collection of keyframes that allow a seamless blend between IK and FK control, or vice versa. On the IK goal, this includes IK keys for:

• Position
• Enabled state
• Swivel angle

On the IK bones, a match frame includes FK keys for:

• Rotation
• Preferred angles
• Scale (less frequently)
