DigitsRigDescription

Inherits from: Instance → Object

Enables interoperability of animations across hand rigs and drives the hand finger solver. Each DigitsRigDescription maps the 15 phalanx joints of one hand (5 fingers with 3 joints each) to engine instances, stores their T-pose adjustments, and exposes forward- and inverse-kinematics helpers for controlling finger poses at runtime.
