Knee Target belongs to the IK limb Lower Leg. This means the object axis of Lower Leg always tries
to reach the position of Knee Target. It succeeds only as far as the IK constraints make it possible. So
don’t over-exert the knee by putting Knee Target too far out of reach. For a smooth movement it is
best to have the target objects within reach of the IK limbs.
Joint is assigned the target object Joint Target. It enables you to control the position of the ankle.
But since the knee has its own target object, the joint is unable to inuence Upper Leg. This is where
MTK comes in. The IK is processed hierarchically — a target object can inuence the IK chain only up
to the next parent target object.
To prevent Toe from dgeting, it is also assigned a target object (Toe Target). With this one you are
able to control the alignment of the foot. Also, to make it even easier to position the foot, Toe Target
has been made a child of Joint Target. So you need to move only Joint Target — Toe Target follows
automatically. You only have to move Toe Target separately if really needed.
Animation
Make sure that only one object is selected before using the Animation tool. If multiple objects are
selected, you’ll be unable to edit their paths.
Selecting this tool lets you edit the animation path of the selected object. You can drag the path’s
points to new positions and you can use the Move, Scale and Rotate tools to move, scale and rotate
the entire path.
