Custom uscenecomponent?

i create custom scenecomponent:

UCLASS( ClassGroup=(Custom), meta=(BlueprintSpawnableComponent) )
class CAVEHYPERCUBUS_API UTestComponent : public USceneComponent
{
	GENERATED_BODY()

public:	
	// Sets default values for this component's properties
	UTestComponent();

protected:
	// Called when the game starts
	virtual void BeginPlay() override;

public:	
	// Called every frame
	virtual void TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction) override;

public:
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Cave)
		class UTextureRenderTarget2D* LeftRenderTarget;

UTestComponent::UTestComponent()
{
	// Set this component to be initialized when the game starts, and to be ticked every frame.  You can turn these features
	// off to improve performance if you don't need them.
	PrimaryComponentTick.bCanEverTick = false;

	USceneCaptureComponent2D* LeftSC = CreateDefaultSubobject<USceneCaptureComponent2D>(TEXT("LeftSceneCapture"));
	LeftSC->SetupAttachment(this);
	LeftSC->TextureTarget = LeftRenderTarget;
}

but it seems dont have any effect.

Delete your intermediate folder, regenerate project files and rebuild & launch the project.
