Member Function Documentation

AddLevel()

virtual void FVirtualTextureChunkStreamingManager::AddLevel ( class ULevel *  Level )

inlineoverridevirtual

Adds a ULevel that has already prepared StreamingData to the streaming manager.

Implements IStreamingManager.

BlockTillAllRequestsFinished()

int32 FVirtualTextureChunkStreamingManager::BlockTillAllRequestsFinished ( float  TimeLimit = 0.0f, bool  bLogResults = false  )

overridevirtual

Blocks till all pending requests are fulfilled.

Parameters

TimeLimit	Optional time limit for processing, in seconds. Specifying 0 means infinite time limit.
bLogResults	Whether to dump the results to the log.

Returns

Number of streaming requests still in flight, if the time limit was reached before they were finished.

Implements IStreamingManager.

CancelForcedResources()

void FVirtualTextureChunkStreamingManager::CancelForcedResources ( )

overridevirtual

Cancels the timed Forced resources (i.e used the Kismet action "Stream In Textures").

Implements IStreamingManager.

GatherProducePageDataTasks() [1/2]

void FVirtualTextureChunkStreamingManager::GatherProducePageDataTasks	(	FVirtualTextureProducerHandle const &	ProducerHandle,
		FGraphEventArray &	InOutTasks
	)		const

GatherProducePageDataTasks() [2/2]

void FVirtualTextureChunkStreamingManager::GatherProducePageDataTasks	(	uint64	RequestHandle,
		FGraphEventArray &	InOutTasks
	)		const

NotifyLevelChange()

virtual void FVirtualTextureChunkStreamingManager::NotifyLevelChange ( )

inlineoverridevirtual

Notifies manager of "level" change.

Implements IStreamingManager.

NotifyLevelOffset()

virtual void FVirtualTextureChunkStreamingManager::NotifyLevelOffset ( class ULevel *  Level, const FVector &  Offset  )

inlineoverridevirtual

Notifies manager that level primitives were shifted

Implements IStreamingManager.

ProduceTile()

IVirtualTextureFinalizer * FVirtualTextureChunkStreamingManager::ProduceTile	(	FRHICommandListBase &	RHICmdList,
		uint32	SkipBorderSize,
		uint8	NumLayers,
		uint8	LayerMask,
		uint64	RequestHandle,
		const FVTProduceTargetLayer *	TargetLayers
	)

RemoveLevel()

virtual void FVirtualTextureChunkStreamingManager::RemoveLevel ( class ULevel *  Level )

inlineoverridevirtual

Removes a ULevel from the streaming manager.

Implements IStreamingManager.

RequestTile()

FVTRequestPageResult FVirtualTextureChunkStreamingManager::RequestTile	(	FRHICommandListBase &	RHICmdList,
		FUploadingVirtualTexture *	VTexture,
		const FVirtualTextureProducerHandle &	ProducerHandle,
		uint8	LayerMask,
		uint8	vLevel,
		uint32	vAddress,
		EVTRequestPagePriority	Priority
	)

SetDisregardWorldResourcesForFrames()

virtual void FVirtualTextureChunkStreamingManager::SetDisregardWorldResourcesForFrames ( int32  NumFrames )

inlineoverridevirtual

Don't stream world resources for the next NumFrames.

Implements IStreamingManager.

UpdateResourceStreaming()

void FVirtualTextureChunkStreamingManager::UpdateResourceStreaming ( float  DeltaTime, bool  bProcessEverything = false  )

overridevirtual

Updates streaming, taking into account all current view infos. Can be called multiple times per frame.

Parameters

DeltaTime	Time since last call in seconds
bProcessEverything	[opt] If true, process all resources with no throttling limits

Implements IStreamingManager.
