CreateSystemTextures()

void CreateSystemTextures

(

FRDGBuilder &

GraphBuilder

)

Registers system textures into RDG.

ENUM_CLASS_FLAGS()

ENUM_CLASS_FLAGS

(

FSceneTextureExtentState::ERenderTargetHistory

)

GetSceneTexture()

FRDGTextureRef GetSceneTexture	(	const FSceneTextures &	SceneTextures,
		ESceneTexture	InSceneTexture
	)

GetSceneTextureExtent()

FIntPoint GetSceneTextureExtent

(

)

Returns the full-resolution scene texture extent.

GetSceneTextureExtentFromView()

FIntPoint GetSceneTextureExtentFromView

(

const FViewInfo &

View

)

Pass through to View.GetSceneTexturesConfig().Extent, useful in headers where the FViewInfo structure isn't exposed.

GetSceneTextureExtracts()

const FSceneTextureExtracts & GetSceneTextureExtracts

(

)

Returns the global scene texture extracts struct.

GetSceneTextureFeatureLevel()

ERHIFeatureLevel::Type GetSceneTextureFeatureLevel

(

)

Returns the feature level being used by the renderer.

GetSceneTextureShaderParameters()

FSceneTextureShaderParameters GetSceneTextureShaderParameters

(

const FSceneView &

View

)

GetSceneTextureUnformBuffer()

TRDGUniformBufferRef< FSceneTextureUniformParameters > GetSceneTextureUnformBuffer

(

const FSceneView &

View

)

InitializeSceneTexturesConfig()

void InitializeSceneTexturesConfig	(	FSceneTexturesConfig &	Config,
		const FSceneViewFamily &	ViewFamily,
		FIntPoint	ExtentOverride = FIntPoint(0, 0)
	)

Initializes a scene textures config instance from the view family.

IsSceneTexturesValid()

bool IsSceneTexturesValid

(

)

Returns whether scene textures have been initialized.

QueueSceneTextureExtractions()

void QueueSceneTextureExtractions	(	FRDGBuilder &	GraphBuilder,

RDG_REGISTER_BLACKBOARD_STRUCT()

RDG_REGISTER_BLACKBOARD_STRUCT

(

FSceneTextures

)

ResetSceneTextureExtentHistory()

void ResetSceneTextureExtentHistory

(

)

Resets the scene texture extent history. Call this method after rendering with very large render targets. The next scene render will create them at the requested size.

SetupMobileSceneTextureUniformParameters()

void SetupMobileSceneTextureUniformParameters	(	FRDGBuilder &	GraphBuilder,
		const FSceneTextures *	SceneTextures,
		EMobileSceneTextureSetupMode	SetupMode,
		FMobileSceneTextureUniformParameters &	SceneTextureParameters
