Variables

	Name	Description
uint8: 1	bCachedDrivenIDsAreDirty	If true, will recalculate DrivenUID values in PoseTargets array on next eval
bool	bEvalFromRefPose	Evaluate SourceBone transform relative from its Reference Pose.
TArray< FCompac...	BonesToFilter	If bFilterDrivenBones, this array lists bones that we should filter out (ie have a track in the PoseAsset, but are not listed in OnlyDriveBones
uint8: 1	bOnlyDriveSelectedBones	If we should filter bones to be driven using the DrivenBonesFilter array
bool	bSoloDrivenOnly	Only solo the driven poses, and don't move the source joint(s) to match
EPoseDriverOutp...	DriveOutput	Whether we should drive poses or curves
EPoseDriverSour...	DriveSource	Which part of the transform is read
FBoneReference	EvalSpaceBone	Optional other bone space to use when reading SourceBone transform.
int32	LODThreshold	Max LOD that this node is allowed to run For example if you have LODThreadhold to be 2, it will run until LOD 2 (based on 0 index) when the component LOD becomes 3, it will stop update/evaluate currently transition would be issue and that has to be re-visited
TArray< FBoneRe...	OnlyDriveBones	If bFilterDrivenBones is specified, only these bones will be modified by this node
TArray< FRBFOut...	OutputWeights	Last set of output weights from RBF solve
TArray< FPoseDr...	PoseTargets	Targets used to compare with current pose and drive morphs/poses
FRBFParams	RBFParams	Parameters used by RBF solver
int32	SoloTargetIndex	The target to solo on, or INDEX_NONE if to use the normal weight computation.
TArray< FBoneRe...	SourceBones	Bone to use for driving parameters based on its orientation
TArray< FTransf...	SourceBoneTMs	Input source bone TM, used for debug drawing
FPoseLink	SourcePose	Bones to use for driving parameters based on their transform

Functions

	Name	Description
float	GetRadiusForTarget ( const FRBFTarget& Target )	Returns the radius for a given target
void	GetRBFTargets ( TArray< FRBFTarget >& OutTargets, const FBoneContainer* BoneCont... )	Return array of FRBFTarget structs, derived from PoseTargets array and DriveSource setting
bool	IsBoneDriven ( FName BoneName )	Util for seeing if BoneName is in the list of driven bones (and bFilterDrivenBones is true)

Overridden from FAnimNode_Base

	Name	Description
void	CacheBones_AnyThread ( const FAnimationCacheBonesContext&... )	Called to cache any bones that this node needs to track (e.g. in a FBoneReference).
void	Evaluate_AnyThread ( FPoseContext& Output )	Called to evaluate local-space bones transforms according to the weights set up in Update().
void	GatherDebugData ( FNodeDebugData& DebugData )	Called to gather on-screen debug data. This is called on the game thread.
int32	GetLODThreshold()	Get the LOD threshold at which this node is enabled.
void	Initialize_AnyThread ( const FAnimationInitializeContext&... )	Initialize function for setup purposes
