Quote - is the pz2 file useful because it's accessed from a cr2 file?   i'm assuming that's the case rather than it being because it's accessed using a readScript, but i figure it's good to check. 

The pz2 is just a carrier and something Poser recognizes as being valid.

I have the idea that there are 2 kinds of library files in Poser: Active and Passive.  Active files bring something into the scene by creating something new.  Passive files just change existing values.  Poses, Cameras, Material Collections, etc are passive - they just change something that already exists.  Figures, Hair, Props are active and bring objects into the scene.

I think this is why it works... marrying the cr2 with a pz2 gives something for Poser to actively load while saying the pz2 portion is part of that cr2 being loaded.

I've been doing this for a while to load new morphs into figures without using "blank slots".  My Samedi and Koneko figures use this in regards to add-ons.  You just load the "loader cr2" and it brings the figure in with the new morphs and you can save the figure back into the Poser library, ready to take more "add-ons" as necessary.
