These options only work if the ``lighting`` argument to ``add_mesh`` is ``True`` (it's ``True`` by default). You can turn off all lighting for the given mesh by passing ``lighting=False`` to ``add_mesh``. See the ``add_mesh`` docs for lighting options: https://docs.pyvista.org/api/plotting/_autosummary/pyvista.Plotter.add_mesh.html ..
