mode

Controls which version of the effect should be used.

Declaration

[Tooltip("Controls which version of the effect should be used.")]
public RayTracingModeParameter mode

Field Value

Type	Description

rayMiss

Controls the fallback hierarchy for indirect diffuse in case the ray misses.

Declaration

[Tooltip("Controls the fallback hierarchy for indirect diffuse in case the ray misses.")]
[FormerlySerializedAs("fallbackHierarchy")]
[AdditionalProperty]
public RayMarchingFallbackHierarchyParameter rayMiss

Field Value

Type	Description

receiverMotionRejection

When enabled, the receiver's movement should be considered a valid rejection condition.

Declaration

[AdditionalProperty]
[Tooltip("When enabled, the receiver's movement should be considered a valid rejection condition.")]
public BoolParameter receiverMotionRejection

Field Value

Type	Description
UnityEngine.Rendering.BoolParameter

sampleCount

Number of samples for evaluating the effect.

Declaration

[Tooltip("Number of samples for GI.")]
public ClampedIntParameter sampleCount

Field Value

Type	Description
UnityEngine.Rendering.ClampedIntParameter

textureLodBias

The LOD Bias HDRP applies to textures in the global illumination.

Declaration
