Detailed Description

A texture/mesh instance manager to manage fully static components. Once an async view has been requested, nothing can be changed as the async view and the internal state point to the same data. This allows for quicker refreshes and also prevent state duplication.

Member Function Documentation

Add() [1/2]

EAddComponentResult FStaticRenderAssetInstanceManager::Add	(	const TArray< FRenderAssetInstanceState::FPreAddComponentPayload > &	Payloads,
		TFunctionRef< void(const FRenderAssetInstanceState::FPreAddComponentPayload &, EAddComponentResult)>	OnAddFailedFunc
	)

Add a batch of components streaming data.

Add() [2/2]

EAddComponentResult FStaticRenderAssetInstanceManager::Add ( const UPrimitiveComponent *  Component, FStreamingTextureLevelContext &  LevelContext, float  MaxAllowedUIDensity  )

finaloverridevirtual

Add a component streaming data, the LevelContext gives support for precompiled data.

Implements IRenderAssetInstanceManager.

CanAddComponent()

bool FStaticRenderAssetInstanceManager::CanAddComponent

(

)

const

Returns whether we can add components to the manager.

CanManage()

bool FStaticRenderAssetInstanceManager::CanManage ( const UPrimitiveComponent *  Component ) const

finaloverridevirtual

Return whether this component is be managed by this manager.

Implements IRenderAssetInstanceManager.

CheckRegistrationAndUnpackBounds()

FORCEINLINE int32 FStaticRenderAssetInstanceManager::CheckRegistrationAndUnpackBounds ( TArray< const UPrimitiveComponent * > &  RemovedComponents )

finaloverridevirtual

Return the size taken for sub-allocation.

Implements IRenderAssetInstanceManager.

GetAsyncView()

const FRenderAssetInstanceView * FStaticRenderAssetInstanceManager::GetAsyncView ( bool  bCreateIfNull )

finaloverridevirtual

Return a view of the data that has to be 100% thread safe. The content is allowed to be updated, but not memory must be reallocated.

Implements IRenderAssetInstanceManager.

GetReferencedComponents()

FORCEINLINE void FStaticRenderAssetInstanceManager::GetReferencedComponents ( TArray< const UPrimitiveComponent * > &  Components ) const

inline

inline

HasRenderAssetReferences()

FORCEINLINE bool FStaticRenderAssetInstanceManager::HasRenderAssetReferences ( ) const

inline

IsReferenced()

FORCEINLINE bool FStaticRenderAssetInstanceManager::IsReferenced ( const UPrimitiveComponent *  Component ) const

inlinefinaloverridevirtual

Return whether this component can be managed by this manager.

Implements IRenderAssetInstanceManager.

NormalizeLightmapTexelFactor()

void FStaticRenderAssetInstanceManager::NormalizeLightmapTexelFactor

(

)

Normalize lightmap texel factors, this is ran on an async tasks.

OffsetBounds()

void FStaticRenderAssetInstanceManager::OffsetBounds

(

const FVector &

Offset

)

Apply specified offset to all cached primitives bounds

OnRefreshVisibilityDone()

void FStaticRenderAssetInstanceManager::OnRefreshVisibilityDone ( int32  InBeginIndex, int32  InEndIndex  )

protected

PrepareAsyncView()

FORCEINLINE void FStaticRenderAssetInstanceManager::PrepareAsyncView ( )

inlinefinaloverridevirtual

Notify the manager that an async view will be requested on the next frame.

Implements IRenderAssetInstanceManager.

Refresh()

void FStaticRenderAssetInstanceManager::Refresh ( float  Percentage )

finaloverridevirtual

Refresh component data (bounds, last render time, min and max view distance) - see RenderAssetInstanceView.

Implements IRenderAssetInstanceManager.

Remove()

void FStaticRenderAssetInstanceManager::Remove ( const UPrimitiveComponent *  Component, FRemovedRenderAssetArray *  RemovedRenderAssets  )

finaloverridevirtual

Remove a component, the RemoveTextures is the list of textures not referred anymore.

Implements IRenderAssetInstanceManager.
