Fields

blurSharpness

Modify the non-temporal blur to change how sharp features are preserved. Lower values leads to blurrier/softer results, higher values gets a sharper result, but with the risk of noise.

Declaration

public ClampedFloatParameter blurSharpness

Field Value

Type	Description
ClampedFloatParameter

directLightingStrength

Controls how much the ambient occlusion affects direct lighting.

Declaration

public ClampedFloatParameter directLightingStrength

Field Value

Type	Description
ClampedFloatParameter

ghostingReduction

Moving this factor closer to 0 will increase the amount of accepted samples during temporal accumulation, increasing the ghosting, but reducing the temporal noise.

Declaration

public ClampedFloatParameter ghostingReduction

Field Value

Type	Description
ClampedFloatParameter

intensity

Controls the strength of the ambient occlusion effect. Increase this value to produce darker areas.

Declaration

public ClampedFloatParameter intensity

Field Value

Type	Description
ClampedFloatParameter

layerMask

Defines the layers that ray traced ambient occlusion should include.

Declaration

public LayerMaskParameter layerMask

Field Value

Type	Description
LayerMaskParameter

occluderMotionRejection

When enabled, ambient occlusion generated by moving objects will not be accumulated, generating less ghosting but introducing additional noise.

Declaration

public BoolParameter occluderMotionRejection

Field Value

Type	Description
BoolParameter

radius

Sampling radius. Bigger the radius, wider AO will be achieved, risking to lose fine details and increasing cost of the effect due to increasing cache misses.

Declaration

public ClampedFloatParameter radius

Field Value

Type	Description
ClampedFloatParameter

rayTracing

Enable ray traced ambient occlusion.

Declaration

public BoolParameter rayTracing

Field Value

Type	Description
BoolParameter

receiverMotionRejection

When enabled, ambient occlusion generated on moving objects will not be accumulated, generating less ghosting but introducing additional noise.

Declaration

public BoolParameter receiverMotionRejection

Field Value

Type	Description
BoolParameter

spatialBilateralAggressiveness

Moving this factor closer to 0 will increase the amount of accepted samples during temporal accumulation, increasing the ghosting, but reducing the temporal noise.

Declaration

public ClampedFloatParameter spatialBilateralAggressiveness

Field Value

Type	Description
ClampedFloatParameter

specularOcclusion

Controls the influence of the ambient occlusion on the specular occlusion.

Declaration

public ClampedFloatParameter specularOcclusion

Field Value

Type	Description
ClampedFloatParameter

temporalAccumulation

Whether the results are accumulated over time or not. This can get higher quality results at a cheaper cost, but it can lead to temporal artifacts such as ghosting.

Declaration

public BoolParameter temporalAccumulation

Field Value

Type	Description
BoolParameter

Properties

bilateralUpsample

This upsample method preserves sharp edges better, however may result in visible aliasing and it is slightly more expensive.

Declaration

public bool bilateralUpsample { get; set; }

Property Value

Type	Description
bool

denoise

Defines if the ray traced ambient occlusion should be denoised.

Declaration

public bool denoise { get; set; }

Property Value

Type	Description
bool

denoiserRadius

Controls the radius of the ray traced ambient occlusion denoiser.

Declaration

public float denoiserRadius { get; set; }

Property Value

Type	Description
float

directionCount

Number of directions searched for occlusion at each each pixel when temporal accumulation is disabled.

Declaration

public int directionCount { get; set; }

Property Value

Type	Description
int

fullResolution

If this option is set to true, the effect runs at full resolution. This will increases quality, but also decreases performance significantly.

Declaration

public bool fullResolution { get; set; }

Property Value

Type	Description
bool

maximumRadiusInPixels

This field imposes a maximum radius in pixels that will be considered. It is very important to keep this as tight as possible to preserve good performance. Note that the pixel value specified for this field is the value used for 1080p when not running the effect at full resolution, it will be scaled accordingly for other resolutions.

Declaration

public int maximumRadiusInPixels { get; set; }

Property Value

Type	Description
int

rayLength

Controls the length of ray traced ambient occlusion rays.

Declaration

public float rayLength { get; set; }

Property Value

Type	Description
float

sampleCount

Number of samples for evaluating the effect.

Declaration

public int sampleCount { get; set; }

Property Value

Type	Description
int

stepCount

Number of steps to take along one signed direction during horizon search (this is the number of steps in positive and negative direction). Increasing the value can lead to detection of finer details, but is not a guarantee of higher quality otherwise. Also note that increasing this value will lead to higher cost.

Declaration

public int stepCount { get; set; }

Property Value

Type	Description
int
