export obj from Poser (I used v. 6)
import to PoseRay 3.8.9
load displacement mesh
export as obj A
export as POV inc
import POV inc
export as obj B
load obj A as morph target in Poser, morph works as expected
load obj B as morph target in Poser, geometry of morph target is 
completely different

End result:  even if you could export from obj to udo for import into 
moray to convert to mesh 2 (so you can actually edit it) then back to 
obj correctly (which you can't), the inc data is not valid.

So how in blazes does one make their own morph target for a poser figure 
outside of directly editing the obj file by hand, assuming they even 
know which points to work with?  'cuz you sure as heck can't do it in 
Moray.  And displacement maps aren't good enough, as they only move the 
faces or vertices along their normals, without allowing precise vertex 
manipulation.  Is there a program which allows simple visual editing of 
an obj, without all the extra features?  I just want to change the shape 
of an existing obj to make a morph target; no addition or deletion of 
anything.

That is the way to do it, for the most part. I think the
subdivision/displacement mapping technique might be effective for adding
musculature to a full body, but for a face morph, you're best doing it by
the vertex in a full-blown modeling app. Blender is free and in the recent
version, it's proportional editing tool is vastly upgraded and great for
morph making.

Er I meant editing by hand in i.e. wordpad.  *shiver*  I tried Blender, 
and find its interface to be...less than user-friendly.  Any tips for 
that?  Moray is straightforward: shift+click selects (just like every 
other windows program), and then you click-drag to move the point. 
Blender is...who knows.  :P

Well, get the 2.37 version of Blender. It's the one with a lot more control
over the proportional editing function. I have a very good python script
for the import/export, better than what's included with Blender, which I
can email you.

And the 2.0 guide is now online at:

http://download.blender.org/documentation/NaN_docs/Manual2.0/TOC2.html

Any questions, just ask. :O)

Might need to be a little careful here though.  I think Wings' greatest 
weakness is as a general mesh editor because it insists on storing 
closed structures.  Other editors do not and therefore unclosed 
structures are common to the point of being the norm.  On import, Wings 
will try to close open structures if it can, that is it will try to 
guess at how to join unassigned edges.  When possible it will assign 
it's "hole" texture to span apparent openings.  This can, all in all, 
make it  unpredictable as a general editor I have found, especially when 
trying to take models from Poser.  Sometimes it works, sometimes not. 
One thing it does not seem to handle well is .obj files with multiple 
groups.  It seems to try to make each group a separate object usually 
resulting in use of the "hole" texture everywhere.
