That's quite disappointing! I too was about to complain bitterly about $40 being demanded for a single added feature, then all of a sudden I found out that I last upgraded last year thus I'm getting it for free...
WHY, THANKS ANDY ! ! !
But... I'm a bit ashamed to ask... what does it do
exactly? What the heck means to
"unwrap" a set of surfaces?
Selecting each surface and mapping it individually is no new stuff, I do that since I can remember, so it must be something subtler and cleverer, but I'll be damned if I can guess what - unless it means that finally an object can support more than one texture, but in that case you would certainly spend more than a few words on the topic.
Maybe my wife is right and I'm not as smart as I look. Who gives me a hint?
