Function Documentation

BeginInitResource()

void BeginInitResource	(	FRenderResource *	Resource,
		FRenderCommandPipe *	RenderCommandPipe = nullptr
	)

Sends a message to the rendering thread to initialize a resource. This is called in the game thread.

BeginReleaseResource()

void BeginReleaseResource	(	FRenderResource *	Resource,
		FRenderCommandPipe *	RenderCommandPipe = nullptr
	)

Sends a message to the rendering thread to release a resource. This is called in the game thread.

BeginUpdateResourceRHI()

void BeginUpdateResourceRHI	(	FRenderResource *	Resource,
		FRenderCommandPipe *	RenderCommandPipe = nullptr
	)

Sends a message to the rendering thread to update a resource. This is called in the game thread.

EndBatchedRelease()

void EndBatchedRelease

(

)

Disables the batching of calls to BeginReleaseResource This is called in the game thread.

ReleaseResourceAndFlush()

void ReleaseResourceAndFlush

(

FRenderResource *

Resource

)

Sends a message to the rendering thread to release a resource, and spins until the rendering thread has processed the message. This is called in the game thread.

StartBatchedRelease()

void StartBatchedRelease

(

)

Enables the batching of calls to BeginReleaseResource This is called in the game thread.

GEnableMipLevelFading

float GEnableMipLevelFading = 1.0f

Whether to enable mip-level fading or not: +1.0f if enabled, -1.0f if disabled.

GMipFadeSettings
