I got a small and bizarre problem. I have the exact same code running to render two meshes of the exact same type, just at different positions and scales. The only light in the scene is a directional light. The attached picture is of the two meshes, both rendered with exactly the same code. The only difference between them is the scale. If I resize the big one to the same size as the small one, its coloring goes to exactly the same as the small one, instead of the grey that it is now. Anyone have any ideas?
