I can't claim that it's well-coded, but this is a Python script which will rip MATs from a cr2/z, pz3/z, or pp2/z.  It should run in Poser 7, but won't work with earlier versions (in that case it needs to be run as a standalone with Python 2.4 or greater installed on the system).

I think there are other scripts or programs out there which do the same thing.  Check for adp001 in the Python forum or free stuff.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
