The C3 Training DVD's are out now and I wanted to say they are excellent to highenders!
I think AE users, Shake users, and definately Maya users without a good compositing package should look into C3 and buy this DVD along side it to find out how robust and elegant Discreets C3 is and yes though not node based persay; extremely powerful.
I've spent several thousand dolllars over more than a decade on training mats in the form of videos, books, etc. but am astonished how great this is for the price.
BTW: I have Zero affiliation with Kenneth La Rue and The Street Productions.
I just love when people and or companies create great learning resources at REASONABLE prices and this one is worth it's weight in pixels.
