GetResourceSizeEx ( FResourceSizeEx& CumulativeResourceSize
)

 Get the size of the object/resource for use in memory tools or to display to artists/LDs in the Editor This is the extended version which separates up the used memory into different memory regions (the actual definition of which may be platform specific).
