Bases:
RigUnit_HighlevelBaseMutable
The FABRIK solver can solve N-Bone chains using the Forward and Backward Reaching Inverse Kinematics algorithm. For now this node supports single effector chains only.

(bool): [Read-Only] Propagate to Children: If set to true all of the global transforms of the children of this bone will be recalculated based on their local transforms. Note: This is computationally more expensive than turning it off.set_effector_transform
(bool): [Read-Write] Set Effector Transform: The option to set the effector transformweight
(float): [Read-Write] Weight: The weight of the solver - how much the IK should be applied.
