Also, there's not really an earth-shattering difference between Amapi 5 and 6, and since v5 comes free with Carrara, you'd be crazy NOT to buy it. And this comes from a die-hard Amapi fan! Also, Litst is being very polite here: Amapi has an incredible modeling toolset, but the renderer SUCKS! Carrara, on the other hand, has middling tools but great rendering (downright incredible in v2), not to mention stuff like terrains, particles, bones in v2, and a ton of other great stuff. Plus, Carrara can use plug-ins, which makes its potential almost limitless. The Digital Carvers Guild has some great plug-ins, like Anything Grows (hair/fur), Anything Grooves (displacement), and a bunch of others, some of which come free with Carrara. And, of course, you can always upgrade Amapi at a later date if you really want the extras v6 offers. I did.
