Visuals

This page describes parameters under the "Visuals" foldout that are shared between all AO modes.

Fadeout

Defines the distance (in meters) at which the occlusion effect fades out. Setting this value to 0 disables fadeout completely, letting AO be visible at any distance.

Performance impact: none

Fadeout 10

Fadeout 50

Fadeout 200

Intensity

Guides the final intensity of the ambient occlusion, higher values result in darker occlusion output.

• For HDRP this corresponds to the Intensity of the SSAO override.

• For URP this corresponds to the Intensity of the SSAO renderer feature.

Performance impact: none

Intensity 1 [GTAO]

Intensity 3 [GTAO]

Direct Lighting Occlusion

Defines how visible the effect is in areas exposed to direct lighting. It's recommended to use 0 for maximum physical accuracy.

• For HDRP this corresponds to the Direct Lighting Strength of the SSAO override.

• For URP this corresponds to the Direct Lighting Strength of the SSAO renderer feature.

Performance impact: none

Direct Lighting Occlusion 0 [RTAO]

Direct Lighting Occlusion 1 [RTAO]

Exclude Receiving [Unity 6000+]

Excludes objects from receiving AO on a per-layer basis via the Rendering Layer Mask. When at least one layer is selected, an additional Intensity slider appears. This slider lets you reduce the AO intensity on the excluded object rather than disabling occlusion entirely. This option is useful for tuning down the effect on meshes that cast overly dark occlusion, such as foliage.

To use this feature, make sure that Rendering Layers are enabled: o use this feature, make sure that Rendering Layers are enabled: HDRP:

▪ Project Settings → Quality → HDRP → Lighting → Rendering Layer Mask Buffer

▪ Camera → Rendering → Custom Frame Settings → Rendering → Rendering Layer Mask Buffer

▪ Project Settings → Graphics → Pipeline Specific Settings → HDRP → Frame Settings (Default Values) → Camera → Rendering → Rendering Layer Mask Buffer

URP:

▪ Universal Rendering Pipeline Asset → Lighting → Use Rendering Layers

In URP this feature is available only in Deferred and Deferrred+ rendering paths.

Exclude Receiving Intensity 1.0

Exclude Receiving Intensity 0.5

Exclude Receiving Intensity 0

Performance impact: small

Early Out [Unity 6000+]

Appears only when at least one layer is selected in the Exclude Receiving mask and Exclude Receiving Intensity is set to 0. Works only in GTAO and RTAO modes.

When this option is enabled, all shader passes skip processing pixels excluded via the Exclude Receiving mask. This can improve performance when a large number of pixels are excluded. It can be useful when AO is required only for a few objects, such as first-person hands, with small and predictable screen coverage.
