class ALightWeightInstanceStaticMeshManager :
public ALightWeightInstanceManager,
public ISMInstanceManager

Variables

	Name	Description
TArray< int32 >	DataIndicesToBeDeleted	Data indices that we are going to delete later in the frame, we impose a small delay to group deletions to avoid cases where we might try to delete the same index multiple times in a frame.
TArray< int32 >	DataIndicesToRenderingIndices
TObjectPtr< cla...	InstancedStaticMeshComponent
TArray< int32 >	RenderingIndicesToDataIndices	Keep track of the relationship between our data and the rendering data stored in the instanced static mesh component
TSoftObjectPtr<...	StaticMesh

Constructors
