Struct bevy::pbr::ScreenSpaceAmbientOcclusionSettings

pub struct ScreenSpaceAmbientOcclusionSettings {
    pub quality_level: ScreenSpaceAmbientOcclusionQualityLevel,
}

Component to apply screen space ambient occlusion to a 3d camera.

Screen space ambient occlusion (SSAO) approximates small-scale, local occlusion of indirect diffuse light between objects, based on what’s visible on-screen. SSAO does not apply to direct lighting, such as point or directional lights.

This darkens creases, e.g. on staircases, and gives nice contact shadows where objects meet, giving entities a more “grounded” feel.

Usage Notes

Requires that you add ScreenSpaceAmbientOcclusionPlugin to your app, and add the DepthPrepass and NormalPrepass components to your camera.

It strongly recommended that you use SSAO in conjunction with TAA (bevy_core_pipeline::experimental::taa::TemporalAntiAliasSettings). Doing so greatly reduces SSAO noise.

SSAO is not supported on WebGL2, and is not currently supported on WebGPU or DirectX12.
