Constructors

PathTracing()

Default constructor for the path tracing volume component.

Declaration
public PathTracing()

Fields

enable

Enables path tracing (thus disabling most other passes).

Declaration
[Tooltip("Enables path tracing (thus disabling most other passes).")]
public BoolParameter enable
Field Value
Type Description
BoolParameter

layerMask

Defines the layers that path tracing should include.

Declaration
[Tooltip("Defines the layers that path tracing should include.")]
public LayerMaskParameter layerMask
Field Value
Type Description
LayerMaskParameter

maximumDepth

Defines the maximum number of bounces for each path, in [minimumDepth, 32].

Declaration
[Tooltip("Defines the maximum number of bounces for each path, in [minimumDepth, 32].")]
public ClampedIntParameter maximumDepth
Field Value
Type Description
ClampedIntParameter

maximumIntensity

Defines the maximum, post-exposed luminance computed for indirect path segments.

Declaration
[Tooltip("Defines the maximum, post-exposed luminance computed for indirect path segments. Lower values help prevent noise and fireflies (very bright pixels), but introduce bias by darkening the overall result. Increase this value if your image looks too dark.")]
public MinFloatParameter maximumIntensity
Field Value
Type Description
MinFloatParameter

maximumSamples

Defines the maximum number of paths cast within each pixel, over time (one per frame).

Declaration
[Tooltip("Defines the maximum number of paths cast within each pixel, over time (one per frame).")]
public ClampedIntParameter maximumSamples
Field Value
Type Description
ClampedIntParameter

minimumDepth

Defines the minimum number of bounces for each path, in [1, 32].

Declaration
[Tooltip("Defines the minimum number of bounces for each path, in [1, 32].")]
public ClampedIntParameter minimumDepth
Field Value
Type Description
ClampedIntParameter

seedMode

Defines the mode used to calculate the noise index.

Declaration
[Tooltip("Defines the mode used to calculate the noise index used per path tracing sample.")]
public SeedModeParameter seedMode
Field Value
Type Description
SeedModeParameter

skyImportanceSampling

Defines if and when sky importance sampling is enabled. It should be turned on for sky models with high contrast and bright spots, and turned off for smooth, uniform skies.

Declaration
[Tooltip("Defines if and when sky importance sampling is enabled. It should be turned on for sky models with high contrast and bright spots, and turned off for smooth, uniform skies.")]
public SkyImportanceSamplingParameter skyImportanceSampling
Field Value
Type Description
SkyImportanceSamplingParameter

tilingParameters

Defines the number of tiles (X: width, Y: height) and the indices of the current tile (Z: i in [0, width[, W: j in [0, height[) for interleaved tiled rendering.

Declaration
[Tooltip("Defines the number of tiles (X: width, Y: height) and the indices of the current tile (Z: i in [0, width[, W: j in [0, height[) for interleaved tiled rendering.")]
public Vector4Parameter tilingParameters
Field Value
Type Description
Vector4Parameter
