class FStreamableTextureResource : public FTextureResource

The rendering resource streamable texture.

Type	Name	Description
TEnumAsByte< ESamplerAddressMode >	AddressU
TEnumAsByte< ESamplerAddressMode >	AddressV
TEnumAsByte< ESamplerAddressMode >	AddressW
bool	bUsePartiallyResidentMips	Whether this texture should be updated using the virtual address mapping for each mip.
ETextureCreateFlags	CreationFlags	Creation flags of the texture
TEnumAsByte< ESamplerFilter >	Filter	Sample config
TextureGroup	LODGroup	The asset LOD group
int8	MaxAniso	Max anisotropy. if 0, will use r.MaxAnisotropy
float	MipBias
EMipFadeSettings	MipFadeSetting	Mip fade settings
EPixelFormat	PixelFormat	Format of the texture
const FTexturePlatformData *	PlatformData	Platform data should be ref counted eventually to remove any synchronization needed when the asset is rebuild.
uint32	SizeX	The width this resource, when all mips are streamed in.
uint32	SizeY	The height when all mips are streamed in.
uint32	SizeZ	The 3d depth for volume texture or num slices for 2d array when all mips are streamed in.
FStreamableRenderResourceState	State	Different states for streaming synchronization.
FName	TextureName	The FName of the texture asset

	Type	Name	Description
		FStreamableTextureResource ( UTexture* InOwner, const FTexturePlatformData* InPlatformData, const FStreamableRenderResourceState& InPostInitState, bool bAllowPartiallyResidentMips )

Type	Name	Description
void	CreatePartiallyResidentTexture ()
void	CreateTexture ()
void	FinalizeStreaming ( FRHITexture* InTextureRHI )
ETextureCreateFlags	GetCreationFlags ()	Return the texture creation flags, does not include TexCreate_Virtual as it could change per mip. Use IsTextureRHIPartiallyResident() instead.
int32	GetCurrentFirstMip ()	Get the current first mip index, of this renderthread resource. Non streaming asset always return 0.
uint32	GetExtData ()
TextureGroup	GetLODGroup ()
EPixelFormat	GetPixelFormat ()
const FTexture2DMipMap *	GetPlatformMip ( int32 MipIdx )	Return the platform data mips, zero based on the resource mip count and not to the asset mip count.
uint64	GetPlatformMipsSize ( uint32 NumMips )	Returns the platform mip size for the given mip count.
TArrayView< const FTexture2DMipMap * >	GetPlatformMipsView ()	Return the platform data mips, zero based on the resource mip count and not to the asset mip count.
FStreamableRenderResourceState	GetPostInitState ()	Get the state it will be in after InitRHI() gets called. Used to synchronize UStreamableRenderResource.CacheStreamableResourceState in CreateResource().
FStreamableRenderResourceState	GetState ()	This is only coherent sync on the rendering thread. To get the gamethread coherent value, use UStreamableRenderResource.CacheStreamableResourceState.
const FName &	GetTextureName ()
void	RefreshSamplerStates ()	Returns the default mip map bias for this texture.

	Type	Name	Description
	FStreamableTextureResource *	GetStreamableTextureResource ()	Dynamic cast methods.
	const FStreamableTextureResource *	GetStreamableTextureResource ()	Dynamic cast methods (const).

Type	Name	Description
uint32	GetSizeX ()	Returns the width of the texture in pixels.
uint32	GetSizeY ()	Returns the height of the texture in pixels.
uint32	GetSizeZ ()	Depth for 3D texture or ArraySize for texture 2d arrays.

	Type	Name	Description
	void	InitRHI ( FRHICommandListBase& RHICmdList )	Initializes the RHI resources used by this resource.
	void	ReleaseRHI ()	Releases the RHI resources used by this resource.
