Atmospheric effects

Atmospheric effects simulate realistic environments by scattering sunlight in unique ways based on properties that control air particles. Using the Atmosphere object, you can:

• Control particle density.
• Create a silhouette or blend distant objects with an offset.
• Simulate a haze or glare.
• Set an atmosphere's color or decay.

Atmosphere properties#

Every property of the Atmosphere object inside the Lighting service works together to support the overall vision, themes, and mood of your game.

Density#

The Density property controls how many particles exist in the air of your game; the higher the density, the more particles, which obstruct a player's view of objects and terrain.

Offset#

The Offset property controls how light transmits between the camera and the sky background. When you increase this value, it creates a horizon silhouette; when you decrease this value, it blends distant objects into the sky for a seemingly endless and seamless open world.

Haze#

The Haze property controls the haziness of the atmosphere to create a visible effect both above the horizon and far into the distance from the camera. To create environmental moods, like a smoky tint for a polluted alien planet or a foggy blue tint for a somber game, combine this property with the Color property.

Color#

The Color property sets the hue of the atmosphere for subtle environmental moods and themes. To expand this property's visible effect, combine it with a high Haze property value.

Glare#

The Glare property sets an atmospheric glare around the sun. A high value results in an increased effect of sunlight cast onto the sky and game. To see this property's visible effect, you must combine a glare with a Haze value higher than 0.

Decay#

The Decay property sets the hue of the atmosphere away from the sun, gradually falling off from Color toward this value. To see this property's visible effect, you must combine a glare with Haze and Glare values higher than 0.
