Cinema 4d $199 or nendo $99 or Rhino $495 Urls in the same order are www.maxon-computer.com http://the-internet-eye.com/free/default.htm http://www.rhino.com/ they all have demos cinema is none saving nendo is save in nendo format only till you buy and rhino is full for 30 days.I would try all free as there quite different and really give the demos some hammer LOL ...I've heard Ampi is pretty good to but only had a quick glimpse...Oh! BTW the second link isn't nendos site its a mag I write for but has the demo (can't recall the proper url)and don't worry to much about the opengl card I had a 200mmx with 2mb crappy card and it ran it fine.............Steve
