 3. Added sub-elements to the MJCF :ref:`material<asset-material>` element, to allow specification of multiple textures
    for rendering (e.g., :ref:`occlusion-roughness-metallic<material-orm>`). Note that the MuJoCo renderer doesn't
    support these new features, and they are made available for use with external renderers.
