Poser used to come with be a set of example scripts in the geomods folder. Not sure if it still exists in P12.

Saving geometry to file does need some explanation.

Current PoserPython comes with a (pretty old) ExportGeom class that provides export to .obj and collada, and a few more. It does not support .fbx, .stel or Alembic.

The method doing the actual export loops over all the actors in the scene and for each actor calls a user-defined method that returns a boolean value to indicate whether the geometry of the actor is to be included in the export.

I have a faster method original, by adp001, extended by yours truly, to write .obj's of a prop or a figure. Drop me a site mail if you want a copy.
