UFUNCTION (BlueprintCallable, Category="Rendering",           Meta=(Keywords="ReadRenderTarget", WorldContext="WorldContextObject")) static FColor ReadRenderTargetPixel (     UObject * WorldContextObject,     UTextureRenderTarget2D * TextureRenderTarget,     int32 X,     int32 Y )

Remarks

Incredibly inefficient and slow operation! Read a value as sRGB color from a render target using integer pixel coordinates. LDR render targets are assumed to be in sRGB space. HDR ones are assumed to be in linear space. Result is 8-bit per channel [0,255] BGRA in sRGB space.
