Function Documentation

◆ AddConditionalClearBlackUAVPass()

void AddConditionalClearBlackUAVPass	(	FRDGBuilder &	GraphBuilder,
		FRDGEventName &&	PassName,
		FRDGTextureRef	Texture,
		const FScreenPassTextureViewport &	ScreenPassViewport,
		FRDGBufferRef	ConditionBuffer,
		uint32	Offset
	)

Clear the UAV texture to black only when ConditionBuffer[Offset] > 0

◆ ClassifySSSTiles()

FSubsurfaceTiles ClassifySSSTiles	(	FRDGBuilder &	GraphBuilder,
		const FViewInfo &	View,
		const FSceneTextures &	SceneTextures,
		const FScreenPassTextureViewportParameters	SceneViewportParameters,
		const FScreenPassTextureViewportParameters	SubsurfaceViewportParameters,
		const bool	IsHalfRes
	)

Code adapted from ScreenSpaceReflectionTiles to reduce Setup SSS cost. Build lists of 8x8 tiles used by SSS pixels Mark and build list steps are separated in order to build a more coherent list (z-ordered over a larger region), which is important for the performance of future passes due to neighbor diffusion.

FVector4f GetSubsurfaceParams ( const FViewInfo & View )

◆ GetSubsurfaceTileParameters()

FSubsurfaceTilePassVS::FParameters GetSubsurfaceTileParameters	(	const FScreenPassTextureViewport &	TileViewport,
