Maybe it will amuse some of you that while trying to figure out how to work around Blender's insistence on ignoring poly groups, I'm pretty sure I just reinvented a trick I (and probably many others, too) used to use years ago:

- Via a script, change the material names to include the group names. So, for example, the polys in the abdomen actor have group "abdomen" and material "skin_BODY", so the script turns that into a material "abdomen:skin_BODY." The lips have group "head" and material "lips", so that becomes "head:lips."

- Edit the file in Blender.

- On the result OBJ, run a second script that restores the original material and group names.

Now that that's sorted, I can start doing little UV fixes with the confidence that I can get them from Blender back into Antonia's geometry file for Poser without bruising my brain in the process.

Can't reproduce your problem.

If I export a figure from Poser and import into Blender ("Keep Vert Order" and "Poly Groups" checked), then export to Wavefront ("OBJ as" all unchecked, "Keep Vertex Order" and "Polygroups" checked), I can import the mesh into Poser and have all groups intact. But all the materialnames has ".001" appended. This happens with Blenders import an can be seen in Blenders material editor. I didn't try it, but https://docs.blender.org/manual/en/latest/files/blend/rename.html should be a tool to help with the problem.
