        // Set some positions
        Vector3[] positions = new Vector3[3];
        positions[0] = new Vector3(-2.0f, -2.0f, 0.0f);
        positions[1] = new Vector3(0.0f, 2.0f, 0.0f);
        positions[2] = new Vector3(2.0f, -2.0f, 0.0f);
        lr.positionCount = positions.Length;
        lr.SetPositions(positions);
