My character "shakes" when I smooth out the camera movement

Hello,
I have a simple character controller and a simple camera controller that is supposed to follow the player in a smooth way (with a lerp).
But when I enable smoothing on the camera, the player’s movement seems jerky…
when I remove the smoothing or when I freeze the camera, the character’s movement is nice again !

Here is a video that shows that…

Here’s my code :

Character Controller :

private void Update()
    {
        // (other stuff)

        rb.MovePosition(rigidbody.position + (moveInput * speed * Time.deltaTime));
    }

Camera Controller

    [SerializeField] private Transform player;
    [SerializeField] private float smooth, smoothAngle;
    [SerializeField] private Vector3 offset;
    private Vector3 referenceVelocity = Vector3.zero;

    private void Update()
    {
        Vector3 desiredPosition = player.position + offset;
        transform.position = Vector3.SmoothDamp(transform.position, desiredPosition, ref referenceVelocity, smooth * Time.deltaTime);

        float smoothedAngle = Mathf.LerpAngle(transform.rotation.eulerAngles.x, angle, smoothAngle * Time.deltaTime);
        transform.rotation = Quaternion.Euler(smoothedAngle, transform.rotation.y, transform.rotation.z);
    }

Hey !

You can try to use FixedUpdate to move your rigibody. It could probably fix your issue, as you can see in Unity example : Unity - Scripting API: Rigidbody.MovePosition

Let me know if it work !
