-* At game / level start, call 'rooms_convert' method on the LRoomManager. This will convert room and portal spatials to LRooms and LPortals, and make portals 2 way.
+* At game / level start, call 'rooms_convert' method on the LRoomManager. This will setup internal room and portal lists within the room manager prepared for fast rendering, and make portals 2 way (LRooms and LPortals are now handled internally within LRoomManager, and as such are separate from the scene graph after initial conversion.)

 Dynamic objects that may move in between rooms (DOBs), like cameras, players, boxes etc are handled slightly differently. You should currently maintain them outside the roomlist, and instead of adding them to the rooms directly, you call:
