public sealed class LensFlareCommonSRP

Fields

maxLensFlareWithOcclusion

Max lens-flares-with-occlusion supported

Declaration

public static int maxLensFlareWithOcclusion

Field Value

Type	Description
int

maxLensFlareWithOcclusionTemporalSample

With TAA Occlusion jitter depth, thought frame on HDRP. So we do a "unanimity vote" for occlusion thought 'maxLensFlareWithOcclusionTemporalSample' frame Important to keep this value maximum of 8 If this value change that could implies an implementation modification on: com.unity.render-pipelines.high-definition/Runtime/PostProcessing/Shaders/LensFlareMergeOcclusionDataDriven.compute

Declaration

public static int maxLensFlareWithOcclusionTemporalSample

Field Value

Type	Description
int

mergeNeeded

Set to 1 to enable temporal sample merge. Set to 0 to disable temporal sample merge (must support 16 bit textures, and the occlusion merge must be written in the last texel (vertical) of the lens flare texture.

Declaration

public static int mergeNeeded

Field Value

Type	Description
int

occlusionRT

occlusion texture either provided or created automatically by the SRP for lens flare. Texture width is the max number of lens flares that have occlusion (x axis the lens flare index). y axis is the number of samples (maxLensFlareWithOcclusionTemporalSample) plus the number of merge results. Merge results must be done by the SRP and stored in the [(lens flareIndex), (maxLensFlareWithOcclusionTemporalSample + 1)] coordinate. Note: It's not supported on OpenGL3 and OpenGLCore

Declaration

public static RTHandle occlusionRT

Field Value

Type	Description
RTHandle
