Quote - MC6 files will not add new material groups unless you allow them to (a confirmation dialog will pop up if you apply an MC6 that contains material groups not present on the currently selected figure or prop).

Hey, that's great to now!
More, there's software like ACDSee that allows renaming of huge file lists in no time...

I thought MC6s were just a fancy way to handle MATs, so glad I have to think back ;)
