IsSkeletalMeshClothBlendEnabled()

bool IsSkeletalMeshClothBlendEnabled

(

)

Returns true if the cloth blend weight defined in the SkeletalMeshComponent should be used by skin rendereding.

UpdatePreviousRefToLocalMatrices()

void UpdatePreviousRefToLocalMatrices	(	TArray< FMatrix44f > &	ReferenceToLocal,
		const FSkinnedMeshSceneProxyDynamicData &	InDynamicData,
		const USkinnedAsset *	InSkinnedAsset,
		const FSkeletalMeshRenderData *	InSkeletalMeshRenderData,
		int32	LODIndex,
		const TArray< FBoneIndexType > *	ExtraRequiredBoneIndices = NULL
	)

Utility function that fills in the array of ref-pose to local-space matrices using the mesh component's updated previous space bases

Parameters

ReferenceToLocal	- matrices to update
InDynamicData	- mesh primitive with updated bone matrices
InSkinnedAsset	- asset used to initialize mesh primitive
InSkeletalMeshRenderData	- resource for which to compute RefToLocal matrices
LODIndex	- each LOD has its own mapping of bones to update
ExtraRequiredBoneIndices	- any extra bones apart from those active in the LOD that we'd like to update

UpdateRefToLocalMatrices()
