Quote - V4's deformers are set up to use an empty geometry file, null.obj.
I did manage to get the zones to appear after saving to and reloading from a PZ3, but to get the base and magnet to show up you'll need to do some text editing.

 

That's why I was asking about a script. There's a bunch of the damn things and going through and changing hidden to 0 and addtomenu to 1 takes some time.
