struct FNDIStaticMesh_InstanceData

Variables

	Name	Description
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
int32	CachedLODIdx	The cached LODIdx used to initialize the FNDIStaticMesh_InstanceData.
uint32	ChangeId	Cached change id off of the data interface.
TWeakObjectPtr<...	Component	Cached ptr to component we sample from.
float	DeltaSeconds	Time separating Transform and PrevTransform.
TSharedPtr< str...	DynamicVertexColorSampler	Allows sampling of the mesh's tris based on a dynamic color range.
UStaticMesh ...	Mesh	Cached ptr to actual mesh we sample from.
int32	MinLOD	The MinLOD, see UStaticMesh::MinLOD which is platform specific.
FMatrix	PrevTransform	Cached ComponentToWorld from previous tick.
FMatrix	PrevTransformInverseTransposed	InverseTranspose of above for transforming normals/tangents.
FStaticMeshFilt...	Sampler	Area weighted sampler for the valid sections.
FMatrix	Transform	Cached ComponentToWorld.
FMatrix	TransformInverseTransposed	InverseTranspose of above for transforming normals/tangents.
TArray< int32 >	ValidSections	Cached results of this filter being applied to the owning mesh.
