Description

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.

Inputs

Name	Description	Permitted Types	Default Value
RootBone	The first bone in the chain to solve	FName	None
Effectors	The list of effectors to use for the solver	TArray<FRigUnit_MultiFABRIK_EndEffector>	()
Precision	The precision to use for the fabrik solver	float	1.000000
bPropagateToChildren	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.	bool	True
