Older files where I've changed the horizon color it seem to work fine and I can adjust it, but if I start new with the startup file and change the world's horizon color it stays grey. I can't seem to find a changed setting anywhere, and this only happens in the game engine works fine in render. How do I fix it? Thanks!
Is the shading next to the mode menu set to textured? Many color options will not work unless that is in the Texture mode.
That was it! Thanks mucho!
