    In particular, transmissive materials may not be visible behind other transmissive materials.
    These limitations affect physically-based transmission, but not alpha-blended non-transmissive materials.
 
+.. note::
+
+   If you want to enable refraction on your model, ``KHR_materials_transmission`` must also

    Transmission is complex for real-time rendering engines to implement,
