Syntax

struct FNDISkeletalMesh_InstanceData

Variables

	Name	Description
bool	bAllowCPUMeshDataAccess	Flag to stub VM functions that rely on mesh data being accessible on the CPU
uint32: 1	bIsGpuUniformlyDistributedSampling	True if the mesh we're using allows area weighted sampling on GPU.
uint32: 1	bUnlimitedBoneInfluences	True if the mesh we're using is to be rendered in unlimited bone influences mode.
TWeakObjectPtr<...	CachedAttachParent	Always reset the DI when the attach parent changes.
UObject *	CachedUserParam
uint32	ChangeId
TWeakObjectPtr<...	Component	Cached ptr to component we sample from. TODO: This should not need to be a weak ptr. We should always be clearing out DIs when the component is destroyed.
float	DeltaSeconds	Time separating Transform and PrevTransform.
int32	ExcludedBoneIndex	Excluded bone for some specific functions, generally the root bone which you don't want to include when picking a random bone.
TArray< uint16 ...	FilteredAndUnfilteredBones	Indices of the bones filtered by the user followed by the unfiltered bones, if this array is empty no filtering is in effect.
int32	FilteredSocketBoneOffset	Bone index of the first socket, sockets are appended to the end of the bone array
TArray< FCached...	FilteredSocketInfo
TStaticArray< T...	FilteredSocketTransforms	Transforms for sockets.
uint32	FilteredSocketTransformsIndex	Index into which socket transforms to use.
USkeletalMesh &...	Mesh
FSkeletalMeshGp...	MeshGpuSpawnDynamicBuffers
FSkeletalMeshGp...	MeshGpuSpawnStaticBuffers	Extra mesh data upload to GPU.
TWeakObjectPtr<...	MeshSafe
const FSkinWeig...	MeshSkinWeightBuffer
uint32	MeshSkinWeightIndexSizeByte
const FSkinWeig...	MeshSkinWeightLookupBuffer
uint32	MeshWeightStrideByte
int32	NumFilteredBones	Number of filtered bones in the array.
int32	NumUnfilteredBones	Number of unfiltered bones in the array.
FMatrix	PrevTransform	Cached ComponentToWorld from previous tick.
FSkeletalMeshSa...	SamplingRegionAreaWeightedSampler	Additional sampler for if we need to do area weighting sampling across multiple area weighted regions.
TArray< int32 >	SamplingRegionIndices	Indices of all valid Sampling regions on the mesh to sample from.
FSkeletalMeshSk...	SkinningData	Handle to our skinning data.
FMatrix	Transform	Cached ComponentToWorld.
FMatrix	TransformInverseTransposed	InverseTranspose of above for transforming normals/tangents.
FNiagaraParamet...	UserParamBinding	A binding to the user ptr we're reading the mesh from (if we are).
