I Add Animation to Character.

Everything is fine. But SkeletalMesh rotate with sight rotation(mouse input).

like this.

When I try to see upside, Mesh rotate.

This is code of Character’s constructor and some of sight rotate function

ATHCharacterBase::ATHCharacterBase()
{
        ......
	FPCameraComponent = CreateDefaultSubobject<UCameraComponent>(TEXT("FirstPersonCamera"));
	FPCameraComponent->SetupAttachment(GetCapsuleComponent());
	FPCameraComponent->SetRelativeLocation(FVector(-39.56f, 1.75f, 64.f));
	FPCameraComponent->bUsePawnControlRotation = true;
	FPCameraComponent->SetFieldOfView(90.0f);
	
	GetMesh()->SetRelativeLocationAndRotation(FVector(0.f, 0.f, -100.f), FRotator(0.f, -90.f, 0.f));
	GetMesh()->SetupAttachment(FPCameraComponent);
	GetMesh()->SetOwnerNoSee(true);
	GetMesh()->SetIsReplicated(true);
	.....
}

void ATHCharacterBase::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
	Super::SetupPlayerInputComponent(PlayerInputComponent);
	.......
	PlayerInputComponent->BindAxis("Turn", this, &ATHCharacterBase::Turn);
	PlayerInputComponent->BindAxis("LookUp", this, &ATHCharacterBase::LookUp);
}

void ATHCharacterBase::Turn(float val)
{
	AddControllerYawInput(val);
}

void ATHCharacterBase::LookUp(float val)
{
	AddControllerPitchInput(val);
}

I don’t know what’s the problem. please tell me what’s wrong.
