Hey guys, I've been working on my game engine for a while now and I'm just about to start implementing lighting with shaders. However, I first implement the fixed-function lighting. The models used within the engine are exported directly from 3DS Max along with the normals. What's happening is I'm getting weird lines across my models when I have lighting enabled. Here are two screenshots with and without lighting. 
I originally thought that maybe my the normals were messed up but it doesn't happen with all models. As you can see from the wall in the background which is exported by the same plugin. Any help? Thanks
