Procedures
To turn off IK on a chain:
1 Select the goal of a chain with an HI Solver.
2 In the Motion panel IK Solver rollout, turn off Enabled.
IK is now off, so you can select and rotate any of the objects in the chain.
Turning IK on and off is animatable using the Auto Key button.
To mix IK and forward kinematics (FK) in a single animation track:
1 Apply an HI IK Solver to a hierarchy or bone system.
2 Turn on the Auto Key button and move the time slider ahead in time.
3 Select the goal of the IK Chain, and open the Motion panel.
4 Select and move the goal to animate the IK chain with Inverse Kinematics.
5 Advance the time slider again.
6 In the IK Solver Rollout, turn off Enabled and IK for FK Pose.
7 Select and rotate the root. The entire hierarchy rotates freely. You are
now adding keyframes using forward kinematics.
To match the goal and the end effector positions:
1 If the goal and end effector become separated, click IK/FK Snap and the
goal will move to match the end link of the chain.
2 If AutoSnap is turned on, clicking the goal will automatically perform
the snap action, matching the goal and end effector positions.
