Giving a property to my class extended from UAnimInstance won’t allow me to compile.


UCLASS(transient, Blueprintable, hideCategories=AnimInstance, BlueprintType)
class MYGAME_API UMyGameCharacterAnimInstance : public UAnimInstance
{
	GENERATED_BODY()

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category=Test)
	float Test;

	virtual void NativeInitializeAnimation() override;
	virtual void NativeUpdateAnimation(float DeltaTimeX) override;

It works if I remove the property flags BlueprintReadWrite and Category=Test, but I need those.

Error: running the .uproject exited with code 5. Please verify that you have sufficient rights.

Edit: fixed, forgot it was in private scope because of class
