Struct bevy_pbr::FogSettings

pub struct FogSettings {
    pub color: Color,
    pub directional_light_color: Color,
    pub directional_light_exponent: f32,
    pub falloff: FogFalloff,
}

Configures the “classic” computer graphics distance fog effect, in which objects appear progressively more covered in atmospheric haze the further away they are from the camera. Affects meshes rendered via the PBR StandardMaterial.

Falloff

The rate at which fog intensity increases with distance is controlled by the falloff mode. Currently, the following fog falloff modes are supported:

• FogFalloff::Linear
• FogFalloff::Exponential
• FogFalloff::ExponentialSquared
• FogFalloff::Atmospheric

Example

commands.spawn((
    // Setup your camera as usual
    Camera3dBundle {
        // ... camera options
    },
    // Add fog to the same entity
    FogSettings {
        color: Color::WHITE,
        falloff: FogFalloff::Exponential { density: 1e-3 },
        ..Default::default()
    },
));

Material Override

Once enabled for a specific camera, the fog effect can also be disabled for individual StandardMaterial instances via the fog_enabled flag.

Fields

color: Color

The color of the fog effect.

Tip: The alpha channel of the color can be used to “modulate” the fog effect without changing the fog falloff mode or parameters.

directional_light_color: Color

Color used to modulate the influence of directional light colors on the fog, where the view direction aligns with each directional light direction, producing a “glow” or light dispersion effect. (e.g. around the sun)

Use Color::NONE to disable the effect.

directional_light_exponent: f32

The exponent applied to the directional light alignment calculation. A higher value means a more concentrated “glow”.

falloff: FogFalloff

Determines which falloff mode to use, and its parameters.
