Read the `blog about PBR `_ for more details. PBR is only supported for :class:`pyvista.PolyData` and can be triggered via the ``pbr`` keyword argument of ``add_mesh``. Also use the ``metallic`` and ``roughness`` arguments for further control. Let's show off this functionality by rendering a high quality mesh of a statue as though it were metallic. ..
