For my scenes, I see no possibility for automatic translation. I use the nodes quite a lot, I have more then just a few procedural nodes. Often, I combine two or three maps with blender nodes for bump or displacement, I don't see how that can be converted automatically. Also, Lux does not have procedurals like granite, clouds, fractals etc, so a relieable automatic conversion could just not work, IMHO.

A ship in port is safe; but that is not what ships are built for.
