Hi, last few days I spent making remake of glxgears. Nothing fancy, I just wanted easily configurable gears. The current performance is only about 70% of glxgears. But I have a problem with shading. Whatever I have been trying, I still don't understand how the shading can be activated. I have light, I have color, but not even Flat shading. Please can you give me a hand? Thanks, Martin PS: I didn't find any attachment size policy for this list, so I hope that the attachment is small enough.
