Hello chaps, stumbled into this the other day.
Will give it a try at some point.
Could be useful for GLB 3d.

Not so sure, NURBS are not great for low poly conversion? Interesting though.
I don´t know how it freezes the mesh when it exports to OBJ (if it subdivides it at all).
But I will check and let us know.
