Member Function Documentation

AddLevel()

void Nanite::FCoarseMeshStreamingManager::AddLevel ( class ULevel *  Level )

overridevirtual

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

Implements IStreamingManager.

AddUsedStreamingHandles()

void Nanite::FCoarseMeshStreamingManager::AddUsedStreamingHandles

(

TArray< CoarseMeshStreamingHandle > &

UsedHandles

)

Add the used streaming handles used by a single FSceneRenderer - called on RenderThread

BlockTillAllRequestsFinished()

int32 Nanite::FCoarseMeshStreamingManager::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 Nanite::FCoarseMeshStreamingManager::CancelForcedResources ( )

overridevirtual

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

Implements IStreamingManager.

NotifyActorDestroyed()

void Nanite::FCoarseMeshStreamingManager::NotifyActorDestroyed ( AActor *  Actor )

overridevirtual

Called when a spawned actor is destroyed.

Reimplemented from IStreamingManager.

NotifyLevelChange()

virtual void Nanite::FCoarseMeshStreamingManager::NotifyLevelChange ( )

inlineoverridevirtual

Notifies manager of "level" change.

Implements IStreamingManager.

NotifyLevelOffset()

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

inlineoverridevirtual

Notifies manager that level primitives were shifted

Implements IStreamingManager.

NotifyPrimitiveDetached()

void Nanite::FCoarseMeshStreamingManager::NotifyPrimitiveDetached ( const UPrimitiveComponent *  Primitive )

overridevirtual

Called when a primitive is detached from an actor or another component.

Reimplemented from IStreamingManager.

NotifyPrimitiveUpdated()

void Nanite::FCoarseMeshStreamingManager::NotifyPrimitiveUpdated ( const UPrimitiveComponent *  Primitive )

overridevirtual

Called when a primitive streaming data needs to be updated.

Reimplemented from IStreamingManager.

NotifyPrimitiveUpdated_Concurrent()

void Nanite::FCoarseMeshStreamingManager::NotifyPrimitiveUpdated_Concurrent ( const UPrimitiveComponent *  Primitive )

overridevirtual

Called when a primitive streaming data needs to be updated in the last stage of the frame.

Reimplemented from IStreamingManager.

RegisterRenderAsset()

void Nanite::FCoarseMeshStreamingManager::RegisterRenderAsset

(

UStreamableRenderAsset *

RenderAsset

)

Register/Unregister streamable nanite coarse mesh static assets

RemoveLevel()

void Nanite::FCoarseMeshStreamingManager::RemoveLevel ( class ULevel *  Level )

overridevirtual

Implements IStreamingManager.

RequestUpdateCachedRenderState()

void Nanite::FCoarseMeshStreamingManager::RequestUpdateCachedRenderState

(

const UStreamableRenderAsset *

RenderAsset

)

Request rebuild of the cached render state for the given handle

SetDisregardWorldResourcesForFrames()

virtual void Nanite::FCoarseMeshStreamingManager::SetDisregardWorldResourcesForFrames ( int32  NumFrames )

inlineoverridevirtual

Don't stream world resources for the next NumFrames.

Implements IStreamingManager.

UnregisterRenderAsset()

void Nanite::FCoarseMeshStreamingManager::UnregisterRenderAsset

(

UStreamableRenderAsset *

RenderAsset

)

UpdateResourceStates()

void Nanite::FCoarseMeshStreamingManager::UpdateResourceStates

(

)

Process all the used streaming handles used by all the scene renderers and find out the new state of the registered resources - called on RenderThread

UpdateResourceStreaming()

void Nanite::FCoarseMeshStreamingManager::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.
