FIGURE 12.34
Duplicate the elbow cubes and point-snap them to the knees.
Note
Ideally, we need these knee controls to exist in front of the knees, but if
we add a pole vector constraint it may adjust the knee positions slightly.
We don't want this to occur until this character is bound to the mesh, so to
keep the joints in position we will leave the icons over the knees.
2.
Select the L_KneePos cube and, holding Shift, select the L_AnkleIK IK handle.
Then go to Constrain > Pole Vector.
3.
Do the same on the opposite leg, selecting R_KneePos and R_AnkleIK before ap-
plying the pole vector constraint.
The knees are now locked to the control cubes and will point toward them no matter where
you position the cubes. Once the character is bound, we can put the cubes in a more suit-
able position.
