As well as holding the same Limb Animation rollout as the rest of the limb the Palm has its own, unique functionality. These include the Digit Manager and the Palm Animation rollout. The same controls are available for ankles.
The Digit Manager provides controls for posing the digits on a palm procedurally. The Digit Manager rollout appears on the Motion panel for a selected palm with one or more digits, although it’s most useful with palms that have multiple digits.
The CAT foot-pivot system lets you position the rotation point of a foot anywhere you like. To use it, simply move the pivot where you want it and rotate the FootPlatform. The foot pivot is animatable, so you simply move it around with Auto Key on, the same way you animate anything in 3ds Max.
