Ouch. Just checked the bug tracker. I've got an issue marked "feedback please" when I attached a comprehensive file EIGHT MONTHS ago. The vertex group names issue has been deleted from the bug tracker -- no-one will even admit it exists any longer (to the detriment of all the users who run into it and mistakenly think they are doing something wrong). I do have a couple of bugs that have been promoted to "assigned," however. Which they've been for over four months, so I don't think they have anywhere near the priority as making sure that Victoria 4 can be used in Carrara without the user having to go to DAZ's competitor (aka Poser.) Pity. It was a nice program for making models once. Streamlined, comfortable to work in, all the basic tools and not too much clutter. No real bubbles important and exporting to Poser or other software (unlike, say, some software, with their strange scale issues, unexpected triangulation, re-ordered vertices and the lot). Still worth it as a render engine though.
