Please check the Function GetDynamicMeshElements in HierarchicalInstancedStaticMesh.cpp.
The Function Traverse in GetDynamicMeshElements will always return two Lod levels, even the transition is finished.
2. Set foliage.DitheredLOD=True
3. Create a HISM actor in level
4. Move camera and makes HISM actor stride two Lod's level.
5. After the dithered LOD transition finished, the drawcalls for HISM is still double. ( two LODs make two drawcalls)
