HumanoidRigDescription

Inherits from: Instance → Object

Stores the joint mapping, reference T-pose and per-joint properties for a bipedal Humanoid character rig. Each of the 22 joints in the rig hierarchy can reference an Instance (typically a Motor6D, AnimationConstraint or Bone), define a T-pose adjustment transform, rotation range limits, and carry a size for volumetric visualization and retargeting. For an example Blender and Maya rig hierarchy with all optional joints, see Character specifications - Advanced R15 rigs.

Use AutoRig to automatically populate joint references from a character model, or assign joints individually. Supports both R6 (6-joint) and R15 (15-joint) rig subsets in addition to the full 22-joint standard set, as well as rigs with more than 22 joints by mapping the key subset of joints.
