Teleport Locomotion with only NavMesh

Hi, I had a similar issue, you can try my solution.

Create a new MonoBehavior script and in runtime create a Mesh Collider from the NavMesh.

Then you just set that collider as a teleport collider.
I'm using Unity 6 and XR 3

    [RequireComponent(typeof(TeleportationArea))]
    public class TeleportationAreaCreator : MonoBehaviour
    {
        void Start()
        {
            var triangulation = NavMesh.CalculateTriangulation();

            var mesh = new Mesh
            {
                vertices = triangulation.vertices,
                triangles = triangulation.indices,
            };

            var mCollider = gameObject.AddComponent<MeshCollider>();
            mCollider.sharedMesh = mesh;

            var teleportationArea = GetComponent<TeleportationArea>();
            teleportationArea.colliders.Add(mCollider);
        }
    }

And after a scene start you can see a new collider, and also you can teleport on it
