Sounds great, Eric.... And as for all my friends jumping to Carrara, well, let's just say that I'm the only person I know in "The Real World" who even could define a Boolean operation, let alone who would be making the jump to CS.... That said, my Renderosity forum friends for the most part have left me in the dust jumping over to Carrara. It's kind of lonely over here in the old Ray Dream world. (Maybe just Jim Z and me, now....) If you hadn't mentioned it, I never would have noticed the tiling of the geometry.... Very nice trick! So, do your shader packs -- squares (which I use a LOT), tile, etc, translate to Carrara well? If so, I can see LOTS of applications with AGr....
