JoePublic - I asked about ears because it seems like they might be the best example of what Spanki writes about, above.  I wouldn't expect the dog or cat ear morphs to be transferrable to a humanoid figure at all, but perhaps between the dog and the cat.  Between human figures, the ears are complex geometries which don't necessarily match up very well at all.  V1 and V3 have ears which are out of line.  But I don't have any V3 ear morphs to test how well they might convert to V1.  Kind of a moot point, however, since the vertex comparison method used in the current testing script wouldn't be used in any further developments.

cobaltdream - I misunderstand readily and often.  :)  Sorry.  I don't mean to suggest that PhilC wouldn't be nice or helpful about any questions.  I would just think it somehow inappropriate myself.  People generally do seem to be protective of their code, even in the Blender world with code released under the GNU public license.  It's kind of hard to go around asking the experts how to do things when you never know whether or not the question might offend them.  Maybe I'm too insecure about irritating people.  Irritating people also seems to be something I do readily and often.  :)

In thinking about switching away from PoserPython to a standalone script, I find myself looking at the potential of Visual Python, PyGeo, and Py2Exe.  Put together, they might enable someone of my limited math skills to produce a script with 3D display of the meshes, allowing some user specification of certain things, and visualization of the process.  Unless the sheer size of the meshes would slow them or my shoddy code could break things again, they could produce something fast which might operate like a MorphManager with a 3D preview.  The trouble with the idea (aside from my limitations) is that this would require installation of Python and several modules, or a distribution of an executable created with Py2Exe or by some other method.  The Py2Exe distributions tend to be rather heavy.  Or it could be a way of making a simple idea complicated.  Does anyone have any experience with any of these modules?  Any thoughts on whether this is a good idea or a bad one?

It all kind of makes me wish I had something other than Python to work with....

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.
