Variables

  Type Name Description
Protected variable 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.
Protected variable TArray< int32 > DataIndicesToRenderingIndices  
Protected variable TObjectPtr< class UHierarchicalInstancedStaticMeshComponent > InstancedStaticMeshComponent  
Protected variable TArray< int32 > RenderingIndicesToDataIndices Keep track of the relationship between our data and the rendering data stored in the instanced static mesh component
Protected variable TSoftObjectPtr< UStaticMesh > StaticMesh
