Enabled

Enable or disable the plugin entirely
r.HBAOPlus.Enabled 1

Mode

Controls how the plugin integrates into the rendering pipeline. 0 — Post Process Pass, composited on top of SceneColor. 1 — Replaces the ScreenSpaceAO buffer during the Deferred Base Pass. This is the recommended mode for most projects.
r.HBAOPlus.Mode 1

Radius

Controls the AO radius in world units. Higher values extend occlusion further from surfaces.
r.HBAOPlus.Radius 100.0

Bias

Adjusts the self-occlusion threshold. Increase this value if you notice unwanted darkening on flat surfaces.
r.HBAOPlus.Bias 0.1

Intensity

Controls the overall strength of the AO effect.
r.HBAOPlus.Intensity 1.5

Quality

Sets the sample quality of the AO. Accepts values from 0 to 3. Higher values produce cleaner results at the cost of performance.
r.HBAOPlus.Quality 2

Blur Sharpness

Controls the depth-based sharpness of the blur pass. Higher values preserve edges more aggressively.
r.HBAOPlus.BlurSharpness 16.0

Normal Sharpness

Controls the normal-based sharpness of the blur pass. Helps preserve occlusion detail along surface transitions.
r.HBAOPlus.NormalSharpness 8.0

Max Pixel Radius

Clamps the maximum screen-space radius of the AO to prevent over-sampling artifacts on surfaces close to the camera.
r.HBAOPlus.MaxPixelRadius 100.0

Half Resolution

Runs the AO at half resolution to improve performance. Disable for sharper results at the cost of additional GPU overhead. 0 — Full resolution 1 — Half resolution
r.HBAOPlus.HalfRes 1

Distance Fade Start

The distance in world units at which the AO effect begins to fade out.
r.HBAOPlus.DistanceFadeStart 15000.0

Distance Fade End

The distance in world units at which the AO effect is fully faded out.
r.HBAOPlus.DistanceFadeEnd 30000.0

Debug Mode

Visualizes the raw AO buffer, useful for tuning parameters. 0 — Off 1 — AO Only
r.HBAOPlus.DebugMode 0

Temporal Accumulation

Enables temporal accumulation and jittering for smoother results over time. Only active when TAA or TSR is enabled.
r.HBAOPlus.TemporalAccumulation 1

Temporal Blend

Controls how much history is accumulated per frame. Higher values produce smoother results but may introduce ghosting on fast-moving geometry.
r.HBAOPlus.TemporalBlend 0.95
