I have been banging my head against a wall here, I can't get normal maps working. The best example i found was this topic:  when i try to edit the demo map, for example i increased the light in the room.... when the light in increased you don't see any bumps on the textures i don't get this? i was after normal mapping, ie parallax mapping? so the height data should create a 3d effect even without lighting so all i can find is these random forum posts all i want is "bump map
