Variables

  Type Name Description
Public variable bool bAllowCPUMeshDataAccess Flag to stub VM functions that rely on mesh data being accessible on the CPU
Public variable uint32: 1 bComponentValid True if SceneComponent was valid on initialization (used to track invalidation of the component on tick)
Public variable uint32: 1 bIsGpuUniformlyDistributedSampling True if the mesh we're using allows area weighted sampling on GPU.
Public variable uint32: 1 bMeshValid True if StaticMesh was valid on initialization (used to track invalidation of the mesh on tick)
Public variable bool bResetOnLODStreamedIn Whether to reset the emitter if any LOD get streamed in.
Public variable uint32: 1 bUnlimitedBoneInfluences True if the mesh we're using is to be rendered in unlimited bone influences mode.
Public variable TWeakObjectPtr< USceneComponent > CachedAttachParent Always reset the DI when the attach parent changes.
Public variable TRefCountPtr< const FSkeletalMeshLODRenderData > CachedLODData The referenced LOD data, used to prevent streaming out LODs while they are being referenced
Public variable int32 CachedLODIdx The cached LODIdx used to initialize the FNDIStaticMesh_InstanceData.
Public variable UObject * CachedUserParam  
Public variable uint32 ChangeId  
Public variable FSkeletalMeshConnectivityHandle Connectivity Handle to connectivity data.
Public variable float DeltaSeconds Time separating Transform and PrevTransform.
Public variable int32 ExcludedBoneIndex Excluded bone for some specific functions, generally the root bone which you don't want to include when picking a random bone.
Public variable 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.
Public variable int32 FilteredSocketBoneOffset Bone index of the first socket, sockets are appended to the end of the bone array
Public variable TArray< FCachedSocketInfo > FilteredSocketInfo  
Public variable TStaticArray< TArray< FTransform3f >, 2 > FilteredSocketTransforms Transforms for sockets.
Public variable uint32 FilteredSocketTransformsIndex Index into which socket transforms to use.
Public variable FSkeletalMeshGpuDynamicBufferProxy * MeshGpuSpawnDynamicBuffers  
Public variable FSkeletalMeshGpuSpawnStaticBuffers * MeshGpuSpawnStaticBuffers Extra mesh data upload to GPU.
Public variable const FSkinWeightDataVertexBuffer * MeshSkinWeightBuffer  
Public variable uint32 MeshSkinWeightIndexSizeByte  
Public variable const FSkinWeightLookupVertexBuffer * MeshSkinWeightLookupBuffer  
Public variable uint32 MeshWeightStrideByte  
Public variable int32 NumFilteredBones Number of filtered bones in the array.
Public variable int32 NumUnfilteredBones Number of unfiltered bones in the array.
Public variable FVector3f PreSkinnedLocalBoundsCenter Preskinned local bounds pulled from attached skeletal mesh
Public variable FVector3f PreSkinnedLocalBoundsExtents  
Public variable FMatrix PrevTransform Cached ComponentToWorld from previous tick.
Public variable FSkeletalMeshSamplingRegionAreaWeightedSampler SamplingRegionAreaWeightedSampler Additional sampler for if we need to do area weighting sampling across multiple area weighted regions.
Public variable TArray< int32 > SamplingRegionIndices Indices of all valid Sampling regions on the mesh to sample from.
Public variable TWeakObjectPtr< USceneComponent > SceneComponent Cached ptr to SkeletalMeshComponent we sample from, when found.
Public variable TWeakObjectPtr< USkeletalMesh > SkeletalMesh  
Public variable FSkeletalMeshSkinningDataHandle SkinningData Handle to our skinning data.
Public variable FMatrix Transform Cached ComponentToWorld of the mesh (falls back to WorldTransform of the system instance).
Public variable FMatrix TransformInverseTransposed InverseTranspose of above for transforming normals/tangents.
Public variable FNiagaraParameterDirectBinding< UObject * > UserParamBinding A binding to the user ptr we're reading the mesh from (if we are).
Public variable FSkeletalMeshUvMappingHandle UvMapping Handle to our uv mapping data.
