Create or rotate Procedural Mesh Component to set it along X axis

[ViaCognita]

Hi!

I’m using Unreal 5.2.1 and creating a Procedural Mesh for the first time.

I have this class:

UCLASS()
class MYPROJECT_API UPStickProceduralMeshComponent : public UProceduralMeshComponent
{
	GENERATED_BODY()

public:
	UPROPERTY(EditAnywhere, Category = "Line Component")
	double Radius{ 100.0f };

	UPROPERTY(EditAnywhere, Category = "Line Component")
	uint32 Side {
		2
	};

	UPROPERTY(EditAnywhere, Category = "Line Component")
	float Thickness{
		1.0f
	};

	UPROPERTY(EditAnywhere, Category = "Line Component")
	FLinearColor Color {
		1.0f, 1.0f, 1.0f, 1.0
	};

	UPROPERTY(EditAnywhere, Category = "Line Component")
	UMaterial* Material{
		nullptr
	};

	UPROPERTY(EditAnywhere, Category = "Line Component")
	float Intensity{
		100.0f
	};

	UPStickProceduralMeshComponent(const FObjectInitializer& ObjectIn);
	

protected:
	UPROPERTY()
	UMaterialInstanceDynamic* MaterialInstanceDynamic{ nullptr };

	// Called when the game starts or when spawned
	virtual void BeginPlay() override;

	virtual void PostLoad() override;

	virtual void PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent) override;

	void BuildMesh();

};

With this BuildMesh code:

void UPStickProceduralMeshComponent::BuildMesh()
{
	TArray<FVector> Vertices;
	TArray<FLinearColor> Colors;
	TArray<FVector> Normals;
	TArray<int32> Triangles;

	FVector Point, DirVert, DirHorz; // Direction Up, Out
	FVector V0, V1, V2, V3;
	FVector LastV0, LastV1, LastV2, LastV3;
	int32 I0, I1, I2, I3;
	int32 LastI0, LastI1, LastI2, LastI3;
	float SinTheta, CosTheta, Theta;
	const float UnitSize = 0.05f;	// Half size of unit 0.1f 

	for (uint32 i = 0; i <= Side; ++i)
	{
		Theta = FMath::DegreesToRadians(i * 360.0f / Side);
		FMath::SinCos<float>(&SinTheta, &CosTheta, Theta);
		
		Point = FVector(SinTheta * Radius, CosTheta * Radius, 0.0f);
		DirVert = FVector(0.0f, 0.0f, 1.0f);
		DirHorz = FVector(SinTheta, CosTheta, 0.0f);

		V0 = Point + DirHorz * UnitSize;
		V1 = Point + DirHorz * -UnitSize;
		V2 = Point + DirVert * UnitSize;
		V3 = Point + DirVert * -UnitSize;

		I0 = Vertices.Add(V0);
		I1 = Vertices.Add(V1);
		I2 = Vertices.Add(V2);
		I3 = Vertices.Add(V3);

		Normals.Add(DirHorz);
		Normals.Add(-DirHorz);
		Normals.Add(DirVert);
		Normals.Add(-DirVert);

		Colors.Add(Color);
		Colors.Add(Color);
		Colors.Add(Color);
		Colors.Add(Color);

		if (i > 0)	// Generate triangles except first index
		{
			Triangles.Add(LastI0); Triangles.Add(I0), Triangles.Add(I1);
			Triangles.Add(I1), Triangles.Add(LastI1), Triangles.Add(LastI0);

			Triangles.Add(LastI2); Triangles.Add(I2), Triangles.Add(I3);
			Triangles.Add(I3), Triangles.Add(LastI3), Triangles.Add(LastI2);
		}

		LastV0 = V0;
		LastV1 = V1;
		LastV2 = V2;
		LastV3 = V3;

		LastI0 = I0;
		LastI1 = I1;
		LastI2 = I2;
		LastI3 = I3;
	}

	CreateMeshSection_LinearColor(0, Vertices, Triangles, Normals, TArray<FVector2D>(), Colors, TArray<FProcMeshTangent>(), false);

	if (MaterialInstanceDynamic == nullptr)
	{
		MaterialInstanceDynamic = UMaterialInstanceDynamic::Create(Material, this);
	}

	MaterialInstanceDynamic->SetScalarParameterValue("Thickness", Thickness);
	MaterialInstanceDynamic->SetScalarParameterValue("Intensity", Intensity);
	SetMaterial(0, MaterialInstanceDynamic);
}

I added the component to an AActor class:

UCLASS()
class MYPROJECT_API APStickActor : public AActor
{
	GENERATED_BODY()
	
public:	
	// Sets default values for this actor's properties
	APStickActor();

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

public:	
	// Called every frame
	virtual void Tick(float DeltaTime) override;

	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	class UPStickProceduralMeshComponent* LineComponent{ nullptr };

};

Code:

APStickActor::APStickActor()
{
	PrimaryActorTick.bCanEverTick = true;

	LineComponent = CreateDefaultSubobject<UPStickProceduralMeshComponent>(TEXT("LineComponent"));
	RootComponent = LineComponent;

}

// Called when the game starts or when spawned
void APStickActor::BeginPlay()
{
	Super::BeginPlay();
	
}

// Called every frame
void APStickActor::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

}

To use it I have created a blueprint class that inherits from it, but when I check the view port for this actor I see that the component has been created along the Y axis and I can’t rotate it:

How can I create it along X axis?

Or maybe, I have to rotate it.

Thanks!
