Syntax
USTRUCT (
Meta=(DisplayName="Multi Effector FABRIK", Category="Hierarchy", Keywords="Multi, Effector, N-Chain,IK", NodeColor="0 1 1"))
struct FRigUnit_MultiFABRIK : public FRigUnit_HighlevelBaseMutable
Remarks
The FABRIK solver can solve multi chains within a root using multi effectors the Forward and Backward Reaching Inverse Kinematics algorithm. For now this node supports single effector chains only.
