When importing an OBJ, I would like the option to save a prop with the geometry OBJ left separate.

Community protocol requires a separate OBJ, remotely referenced by the pp2, just as the texturing image files remain separate.  For the new folks, the reason for this is that a stripped pp2 can be re-textured by a third party texture artist and offered without violating copyright because they are not re-distributing the geometry OBJ.  It also saves greatly on file size because you can have several differently-textured versions of the cottage, but they all share the same geometry file(s).

Poser currently incorporates the geometry into the pp2, if you import an OBJ and save it as a prop.
This means that if you want to post the prop as a freebie, you have to go through the process of stripping the geometry back out.

Kudos to Dimesion3D's suite of Poser content prep tools, and to John Hoagland for his free Geometry Stripper, by the way.  :D
