  It's difficult to understand your question. Could you try rephrasing it and adding some more detail so we can better understand? For example, what do you mean by 'load'? Are you writing a game engine? A game? An editor?   ;  i try write 3d engine.i can load map file from x file.i want load and render object and character on the map.i am sorry bad english.
