Variables

Type	Name	Description
TArray< FRigUnit_RigLogic_IntArray >	BlendShapeIndices	RL mesh+blend shape array index to RL blend shape index for each LOD
uint32	CurrentLOD	LOD for which the model is rendered
TArray< FRigUnit_RigLogic_IntArray >	CurveElementIndicesForAnimMaps	RL animated map index to ControlRig's output anim map curve index for each LOD
TArray< int32 >	HierarchyBoneIndices	RL joint index to ControlRig's hierarchy bone index
TArray< int32 >	InputCurveIndices	Mapping RL indices to UE indices Note: we use int32 instead of uint32 to allow storing INDEX_NONE for missing elements if value is valid, it is cast to appropriate uint typeRL input index to ControlRig's input curve index
TSharedPtr< FSharedRigRuntimeContext >	LocalRigRuntimeContext
TArray< FRigUnit_RigLogic_IntArray >	MorphTargetCurveIndices	RL mesh blend shape index to ControlRig's output blendshape curve index for each LOD
TArray< int32 >	NeuralNetMaskCurveIndices	RL neural network mask index to ControlRig's input curve index
TUniquePtr< FRigInstance >	RigInstance	RigInstance is a thin class, containing only character instance specific data i.e. the output buffers where RigLogic writes the results of computations, specific to each instance of a rig.
TArray< FRigUnit_RigLogic_IntArray >	RigLogicIndicesForAnimMaps	RL animated map index to RL anim map curve index for each LOD
TWeakObjectPtr< USkeletalMeshComponent >	SkelMeshComponent	Cached Skeletal Mesh Component
