USceneCaptureComponent2D produces a black image

[anonymous_user_b1fd2ba6]

I am trying to take a snapshot of a USceneCaptureComponent2D and save to an image, I implemented my approach both in the scene and in code, in the case of connecting the components in the scene, I did the following:

1. connected the USceneCaptureComponent2D to a render target in its properties
2. applied the render target to a material
3. then applied the material to a plane
   This is working as supposed.

In the case of implementing a similar approach in the code, I made a node that takes the USceneCaptureComponent2D and the RenderTarget, sets the RenderTarget as a TextureTarget for the CaptureConponent, Captures the scene as follwos:

TArray<FColor> ALedCommBase::GetCameraViewAvgColor(USceneCaptureComponent2D *nativeSceneCapture, UTextureRenderTarget2D *nativeRenderTarget2D){

	nativeSceneCapture->TextureTarget = nativeRenderTarget2D;
	nativeSceneCapture->CaptureScene();
	nativeRenderTarget2D->UpdateResourceImmediate();
	UTexture2D* Aux2DTex = UTexture2D::CreateTransient(nativeRenderTarget2D->SizeX, nativeRenderTarget2D->SizeY, PF_A16B16G16R16);//PF_B8G8R8A8);
	
	#if WITH_EDITORONLY_DATA
		Aux2DTex->MipGenSettings = TextureMipGenSettings::TMGS_NoMipmaps;
	#endif
	
	//Turn off Gamma-correction
	Aux2DTex->SRGB = nativeRenderTarget2D->SRGB;;

	// Saving data to image
	TArray<FColor> SurfData;
	FRenderTarget* TargetResource = nativeRenderTarget2D->GameThread_GetRenderTargetResource();
	FString FileLocation = FString("Snapshot");
	TargetResource->ReadPixels(SurfData);
	SavePixelBufferToFile(SurfData,FileLocation, nativeRenderTarget2D->SizeX, nativeRenderTarget2D->SizeY);

	Aux2DTex->PlatformData->Mips[0].BulkData.Unlock();
	Aux2DTex->UpdateResource();
	return SurfData;
}

the other function I use to do the part of saving the color array to an image is as follows:

void ALedCommBase::SavePixelBufferToFile(TArray<FColor> RawPixels, FString& FileLocation, int32 pWidth, int32 pHeight)
{
	// Save Texture to jpg
	FString GameDir = FPaths::ConvertRelativePathToFull(FPaths::ProjectDir());
	FString PicsDir = FPaths::Combine(*GameDir, TEXT("ScreenShots"));
	FString Filename = FileLocation+TEXT("-DC-") + FGuid::NewGuid().ToString();
	FileLocation = FPaths::Combine(*PicsDir, *Filename);
	TSharedPtr<IImageWrapper> ImageWrapper = NULL;
	IImageWrapperModule& ImageWrapperModule = FModuleManager::LoadModuleChecked<IImageWrapperModule>(FName("ImageWrapper"));

	ImageWrapper = ImageWrapperModule.CreateImageWrapper(EImageFormat::PNG);
	FileLocation += ".png";
	
	if (ImageWrapper.IsValid())
	{
		if (ImageWrapper->SetRaw(RawPixels.GetData() , RawPixels.Num() * sizeof(FColor), pWidth, pHeight, ERGBFormat::RGBA, 8))
		{
			FFileHelper::SaveArrayToFile(ImageWrapper->GetCompressed(), *FileLocation);
		}
	}
}

But I get a black image always.
Does anybody know if I am skipping something?

Here is a screenshot of the node.
