Expand description

When placed on a Camera3d, enables volumetric fog and volumetric lighting, also known as light shafts or god rays.

Fields§

§fog_color: Color

The color of the fog.

Note that the fog must be lit by a VolumetricLight or ambient light in order for this color to appear.

Defaults to white.

§ambient_color: Color

Color of the ambient light.

This is separate from Bevy’s AmbientLight because an EnvironmentMapLight is still considered an ambient light for the purposes of volumetric fog. If you’re using a EnvironmentMapLight, for best results, this should be a good approximation of the average color of the environment map.

Defaults to white.

§ambient_intensity: f32

The brightness of the ambient light.

If there’s no EnvironmentMapLight, set this to 0.

Defaults to 0.1.

§step_count: u32

The number of raymarching steps to perform.

Higher values produce higher-quality results with less banding, but reduce performance.

The default value is 64.

§max_depth: f32

The maximum distance that Bevy will trace a ray for, in world space.

You can think of this as the radius of a sphere of fog surrounding the camera. It has to be capped to a finite value or else there would be an infinite amount of fog, which would result in completely-opaque areas where the skybox would be.

The default value is 25.

§absorption: f32

The absorption coefficient, which measures what fraction of light is absorbed by the fog at each step.

Increasing this value makes the fog darker.

The default value is 0.3.

§scattering: f32

The scattering coefficient, which measures the fraction of light that’s scattered toward, and away from, the viewer.

The default value is 0.3.

§density: f32

The density of fog, which measures how dark the fog is.

The default value is 0.1.

§scattering_asymmetry: f32

Measures the fraction of light that’s scattered toward the camera, as opposed to away from the camera.

Increasing this value makes light shafts become more prominent when the camera is facing toward their source and less prominent when the camera is facing away. Essentially, a high value here means the light shafts will fade into view as the camera focuses on them and fade away when the camera is pointing away.

The default value is 0.8.

§light_tint: Color

Applies a nonphysical color to the light.

This can be useful for artistic purposes but is nonphysical.

The default value is white.

§light_intensity: f32

Scales the light by a fixed fraction.

This can be useful for artistic purposes but is nonphysical.

The default value is 1.0, which results in no adjustment.
