An atmospheric special effect that mimics the real world tendency of an object to fade by a certain amount as it moves off into the distance.
A rendering technique that can be used to simulate atmospheric effects such as haze, fog, and smog by fading object colors to a background color based on distance from the viewer. Fog also aids in the perception of distance from the viewer, giving a depth cue.
Found under the Environment menu, this function simulates a uniform thickness fog whose strength and even color can be controlled. The Near and Far functions control how quickly objects fade into the fog, depending on their distance.
