I am sorry that I haven't responded promptly to all emails in the last couple of weeks. I'm a little preoccupied with a work project.
I am working on an update to fix many of the $bodygroup export functions that were broken last year when I updated the WW SMD Exporter to support $origin in CS:GO and SFM. Along with a fix to that, I am adding support for reusing objects in different bodygroups.
I'll try to release that update this or next week.
Also, I will be doing an English language video tutorial showing people how to use the PolygonMap plugin from VG Plugins (http://www.vg2max.spb.ru/PolygonMap.htm) soon. I'm doing it as a collaboration with the developer Vladislav Gavrilov.
