Variables

	Name	Description
FPoseLink	BasePose	The source pose
bool	bBlendRootMotionBasedOnRootBone	Whether to incorporate the per-bone blend weight of the root bone when lending root motion
bool	bHasRelevantPoses
TArray< TObject...	BlendMasks	The blend masks to use for our layer inputs.
ELayeredBoneBle...	BlendMode	Whether to use branch filters or a blend mask to specify an input pose per-bone influence
TArray< FPoseLi...	BlendPoses	Each layer's blended pose
TArray< float >	BlendWeights	The weights of each layer
bool	bMeshSpaceRotationBlend	Whether to blend bone rotations in mesh space or in local space
bool	bMeshSpaceScaleBlend	Whether to blend bone scales in mesh space or in local space
TArray< FPerBon...	CurrentBoneBlendWeights
TEnumAsByte< en...	CurveBlendOption	How to blend the layers together
TArray< uint8 >	CurvePoseSourceIndices
TArray< FPerBon...	DesiredBoneBlendWeights	Transient data to handle weight and target weight this array changes based on required bones
TArray< FInputB...	LayerSetup	Configuration for the parts of the skeleton to blend for each layer.
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< FPerBon...	PerBoneBlendWeights	Per-bone weights for the skeleton.
uint16	RequiredBonesSerialNumber	Serial number of the required bones container.
FGuid	SkeletonGuid	Guids for skeleton used to determine whether the PerBoneBlendWeights need rebuilding.
FGuid	VirtualBoneGuid	Guid for virtual bones used to determine whether the PerBoneBlendWeights need rebuilding.

Functions

	Name	Description
void	AddPose()
void	InvalidateCachedBoneData()	Invalidates the cached bone data so it is recalculated the next time this node is updated.
void	InvalidatePerBoneBlendWeights()	Invalidate the cached per-bone blend weights from the skeleton.
void	RemovePose ( int32 PoseIndex )

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&... )	Called when the node first runs.
void	Update_AnyThread ( const FAnimationUpdateContext& Con... )	Called to update the state of the graph relative to this node.
