Declaration
public ClampedFloatParameter accumulationFactor
Field Value
Type Description
ClampedFloatParameter

ambientProbeDimmer

Controls the dimmer applied to the ambient and legacy light probes.

Declaration
[Tooltip("Controls the dimmer applied to the ambient and legacy light probes.")]
public ClampedFloatParameter ambientProbeDimmer
Field Value
Type Description
ClampedFloatParameter

biasFactor

For PBR: Controls the bias of accumulation (0 no bias, 1 bias ssr)

Declaration
public ClampedFloatParameter biasFactor
Field Value
Type Description
ClampedFloatParameter

bounceCount

Number of bounces for reflection rays.

Declaration
public ClampedIntParameter bounceCount
Field Value
Type Description
ClampedIntParameter

depthBufferThickness

Controls the distance at which HDRP fades out SSR near the edge of the screen.

Declaration
public ClampedFloatParameter depthBufferThickness
Field Value
Type Description
ClampedFloatParameter

enableWorldSpeedRejection

When enabled, world space speed from Motion vector is used to reject samples.

Declaration
public BoolParameter enableWorldSpeedRejection
Field Value
Type Description
BoolParameter

enabled

Enable Screen Space Reflections.

Declaration
[Tooltip("Enable Screen Space Reflections.")]
public BoolParameter enabled
Field Value
Type Description
BoolParameter

enabledTransparent

Enable Transparent Screen Space Reflections.

Declaration
[Tooltip("Enable Transparent Screen Space Reflections.")]
public BoolParameter enabledTransparent
Field Value
Type Description
BoolParameter

lastBounceFallbackHierarchy

Controls the fallback hierarchy for lighting the last bounce.

Declaration
public RayTracingFallbackHierachyParameter lastBounceFallbackHierarchy
Field Value
Type Description
RayTracingFallbackHierachyParameter

layerMask

Layer mask used to include the objects for screen space reflection.

Declaration
public LayerMaskParameter layerMask
Field Value
Type Description
LayerMaskParameter

mode

Controls which version of the effect should be used.

Declaration
public RayTracingModeParameter mode
Field Value
Type Description
RayTracingModeParameter

rayMiss

Controls which sources are used to fallback on when the traced ray misses.

Declaration
[FormerlySerializedAs("fallbackHierachy")]
public RayTracingFallbackHierachyParameter rayMiss
Field Value
Type Description
RayTracingFallbackHierachyParameter

reflectSky

When enabled, SSR handles sky reflection for opaque objects (not supported for SSR on transparent).

Declaration
public BoolParameter reflectSky
Field Value
Type Description
BoolParameter

sampleCount

Number of samples for reflections.

Declaration
public ClampedIntParameter sampleCount
Field Value
Type Description
ClampedIntParameter

screenFadeDistance

Controls the typical thickness of objects the reflection rays may pass behind.

Declaration
public ClampedFloatParameter screenFadeDistance
Field Value
Type Description
ClampedFloatParameter

speedRejectionParam

Controls the likelihood history will be rejected based on the previous frame motion vectors of both the surface and the hit object in world space.

Declaration
public FloatParameter speedRejectionParam
Field Value
Type Description
FloatParameter

speedRejectionScalerFactor

Controls the upper range of speed. The faster the objects or camera are moving, the higher this number should be.

Declaration
public ClampedFloatParameter speedRejectionScalerFactor
Field Value
Type Description
ClampedFloatParameter

speedSmoothReject

When enabled, history can be partially rejected for moving objects which gives a smoother transition. When disabled, history is either kept or totally rejected.
