Erm...

OK, I was trying to design a really simple D3D .x mesh file loader. I''ve been using the D3DX libraries to load it etc. but when I try to actually run it with lighting, really horrible stuff happens, like all the normals are messed up. Erm... The optimised and enhanced mesh examples are kinda difficult to understand as they''re written really horribly and I think (and hope) that there''s loads of stuff in them that I don''t really need. The mesh tutorial doesn''t have lighting (so may well have the same problem as mine!). Erm... What should I do?
