sky horizon_sky { // A backdrop texture's horizontal size must be a power of 2; // the vertical size does not matter type = <horizon.pcx>; tilt = -10; flags = scene,overlay,visible; layer = 3; }
/*sky horizon_sky { // A backdrop texture's horizontal size must be a power of 2; // the vertical size does not matter type = <horizon.pcx>; tilt = -10; flags = scene,overlay,visible; layer = 3; }*/
