class UTextureRenderTarget : public UTexture

Variables

  Type Name Description
Public variable uint32: 1 bCanCreateUAV If true, it will be possible to create a FUnorderedAccessViewRHIRef using RHICreateUnorderedAccessView and the internal FTextureRHIRef.
Public variable uint32: 1 bNeedsTwoCopies If true, there will be two copies in memory - one for the texture and one for the render target.
Public variable uint32: 1 bTargetArraySlicesIndependently If true, RTVs will be created for each slice (texture array and/or cube).
Public variable UProperty Category, EditAnywhere BlueprintReadWrite float TargetGamma Will override FTextureRenderTarget2DResource::GetDisplayGamma if > 0.

Constructors

  Type Name Description
Public function  

UTextureRenderTarget ( const FObjectInitializer& ObjectInitializer
)

  

Functions

  Type Name Description
Public function Virtual Const bool

CanConvertToTexture ( ETextureSourceFormat& OutTextureSourceFormat,
EPixelFormat& OutPixelFormat,
FText* OutErrorMessage
)

 Validates that the UTextureRenderTarget can be converted to a UTexture (e.g. supported format, valid size, etc.)
Public function Const bool

CanConvertToTexture ( FText* OutErrorMessage
)

 Validates that the UTextureRenderTarget can be converted to a UTexture (e.g. supported format, valid size, etc.)
Public function UTexture *

ConstructTexture ( UObject* InOuter,
const FString& InNewTextureName,
EObjectFlags InObjectFlags,
EConstructTextureFlags InFlags,
const TArray< uint8 >* InAlphaOverride,
FText* OutErrorMessage
)

 Utility for creating a new UTexture from a UTextureRenderTarget.
Public function FTextureRenderTargetResource * Returns a pointer to the (game thread managed) render target resource.
Public function Static float UTextureRenderTarget default display gamma if none is set returns hard-coded 2.2
Public function Virtual Const float  
Public function Virtual Const EPixelFormat  
Public function Static ERawImageFormat::Type

GetReadPixelsFormat ( EPixelFormat PF,
bool bIsVolume
)

 Get the variant of ReadPixels call that should be used either BGRA8,RGBA32F,or RGBA16F for FColor,FLinearColor, or Float16
Public function FTextureRenderTargetResource * Render thread: Access the render target resource for this texture target object
Public function Virtual Const ETextureClass GetTextureClass() will just return "RenderTarget" ; to get the sub-type (2d/cube), use GetRenderTargetTextureClass.
Public function Virtual Const TSubclassOf< UTexture > Returns the UTexture class that corresponds to this render target (e.g. UTexture2D for UTextureRenderTarget2D)
Public function Virtual Const bool

IsSRGB ()

  
Public function bool

UpdateTexture ( UTexture* InTexture,
EConstructTextureFlags InFlags,
const TArray< uint8 >* InAlphaOverride,
FOnTextureChangingDelegate InOnTextureChangingDelegate,

)

  
Protected function Const ETextureSourceFormat

ValidateTextureFormatForConversionToTextureInternal ( EPixelFormat InFormat,
const TArrayView< const EPixelFormat >& InCompatibleFormats,
FText* OutErrorMessage
)

  

Overridden from UTexture

  Type Name Description
Public function Virtual FTextureResource * Implemented by subclasses to create a new resource for the texture.
Public function Virtual Const EMaterialValueType  
Public function Virtual Const ETextureClass Get Texture Class
