struct FNDIStaticMesh_InstanceData

Variables

	Name	Description
uint32: 1	bComponentValid	True if SceneComponent was valid on initialization (used to track invalidation of the component on tick)
uint32: 1	bIsCpuUniformlyDistributedSampling	True if the mesh we're using allows area weighted sampling on CPU.
uint32: 1	bIsGpuUniformlyDistributedSampling	True if the mesh we're using allows area weighted sampling on GPU.
uint32: 1	bMeshAllowsCpuAccess	True if the mesh allows CPU access. Use to reset the instance in the editor
uint32: 1	bMeshValid	True if StaticMesh was valid on initialization (used to track invalidation of the mesh on tick)
uint32: 1	bUsePhysicsVelocity	True if velocity should not be calculated via the transforms, but rather read the physics data from the mesh component
int32	CachedLODIdx	The cached LODIdx used to initialize the FNDIStaticMesh_InstanceData.
TArray< FTransf...	CachedSockets	Cached socket information, if available
uint32	ChangeId	Cached change id off of the data interface.
float	DeltaSeconds	Time separating Transform and PrevTransform.
TSharedPtr< str...	DynamicVertexColorSampler	Allows sampling of the mesh's tris based on a dynamic color range.
TArray< uint16 ...	FilteredAndUnfilteredSockets	Filter sockets followed by unfiltered sockets
int32	MinLOD	The MinLOD, see UStaticMesh::MinLOD which is platform specific.
int32	NumFilteredSockets	Number of filtered sockets.
FVector	PhysicsVelocity	Velocity set by the physics body of the mesh component
FQuat	PrevRotation	Cached Previous Rotation.
FMatrix	PrevTransform	Cached ComponentToWorld from previous tick.
FQuat	Rotation	Cached Rotation.
FStaticMeshFilt...	Sampler	Area weighted sampler for the valid sections.
TWeakObjectPtr<...	SceneComponent	Cached ptr to StaticMeshComponent we sample from, when found.
TWeakObjectPtr<...	StaticMesh	Cached ptr to the mesh so that we can make sure that we haven't been deleted.
FMatrix	Transform	Cached ComponentToWorld. (Falls back to WorldTransform of the system instance)
FMatrix	TransformInverseTransposed	InverseTranspose of above for transforming normals/tangents.
TArray< int32 >	ValidSections	Cached results of this filter being applied to the owning mesh.
