Here's a question for @adp001 or another Poser Python sorcerer: if I pull this off, it would be nice to eventually run the code from within Poser, possibly as part of the OBJ_ImExport script. The problem is that right now there seems to be no way to directly write subdivision deltas via Poser Python. So I imagine the script would have to write a PMD and associated PZ2 "by hand" and then (ideally) load and "execute" them in order to create the morph in the current session.

So are these things that one can do from within Poser, namely a) create a file with arbitrary content and then b) load that file back into Poser as if the user had opened it from the pose library?
