Atmosphere
Fog properties are hidden when Lighting contains an Atmosphere object.
The Atmosphere object pushes Roblox closer toward realistic environments where sunlight scatters in different ways depending on density and other air particle properties. It simulates real-world "aerial perspective" and lets you control light transmission from the background sky through distant objects. Furthermore, it controls haze and glare conditions, letting you tune a perfect sunset, foggy afternoon, and more.

Summary
Properties
Changes the Atmosphere hue for subtle environmental moods.
When used with increased Atmosphere.Haze and Atmosphere.Glare, defines the hue of the Atmosphere away from the sun, gradually falling off from Atmosphere.Color towards this value.
Defines the amount of particles in the Atmosphere and essentially controls how much in-game objects/terrain will be obscured by them.
When used with increased Atmosphere.Haze, specifies the glow/glare of the Atmosphere around the sun. More glare results in an increased effect of sunlight cast onto the sky and world.
Defines the haziness of the Atmosphere with a visible effect both above the horizon and into the distance.
Controls how light transmits between the camera and the sky background.
Properties
Color
A Color3 value which changes the Atmosphere hue for subtle environmental moods. This is best combined with increased Atmosphere.Haze to expand the visible effect.
Decay
Defines the hue of the Atmosphere away from the sun, gradually falling off from Atmosphere.Color towards this value. Must be used with Atmosphere.Haze and Atmosphere.Glare levels higher than 0 to see any effect.
Density
Defines the amount of particles in the air. The higher the density, the more particles and the more in-game objects/terrain will be obscured by them. Note that density does not directly affect the skybox — it merely affects in-game objects/terrain and visibility of the skybox through them.
Glare
Specifies the glow/glare of the Atmosphere around the sun. More glare results in an increased effect of sunlight cast onto the sky and world. Must be used with a Atmosphere.Haze level higher than 0 to see any effect.
Haze
Defines the haziness of the Atmosphere with a visible effect both above the horizon and into the distance. This can be combined with Atmosphere.Color to create environmental moods, like a grey tint for a polluted alien planet.
Offset
Controls how light transmits between the camera and the sky background. Increase this value to create a horizon silhouette against the sky or reduce it to blend distant objects into the sky for an endless and seamless open world.
Offset should be balanced against Atmosphere.Density and carefully tested in your place. A low offset may cause "ghosting" where the skybox can be seen through objects/terrain. This can be corrected by increasing the offset, which more clearly silhouettes distant objects/terrain against the sky, but too much offset may reveal level-of-detail "popping" for far distant terrain and meshes.
