Autoconforming:  There are different community meanings for this.  If you mean old system where "Figure xx" and number references have been removed from :xx (where xx is a number).  We don't need this anymore.  Save the clothing back in the library to get the clothing back to normal, reload, and use "Include morphs" in the BODY properties tab instead.

Then when you're dealing with clothing, untick the box if it's giving you trouble, when using Copy Morphs From.

And yes, I'm only talking about roughly Poser 9+ usage.  If you're making things so they work back to circa 2001, you'll have to deal with additional issues and caveats. ;)

As I've said (too) frequently, I'll step back a couple of versions if possible but I'm not going back to olden days, no thanks.  There's a reason software gets advanced and tweaked and IMHO, you have to reasonably stay within a couple versions of what is contemporary.
