For the money they want for Bryce 5, you could spend a tiny bit more and get Carrara 1.1 Studio and Amapi v5. I have Bryce 4.1, and am a longtime Raydream/Carrara user. One of my friends has Bryce 4 and is buying the Carrara/Amapi package from eovia. The upgrade price for Bryce seems a bit steep($159.00???) I only paid $179 for Bryce 4 to begin with. For most current Bryce 4 users I think they could spend their money on something else that would add to Bryce. Hell eovia is only charging $149 to upgrade from Raydream studio to Carrara Studio, with Amapi. By the way is anyone is interested, you can download Amapi v4.15 for free right now at http://www.insidecg.com/downloads.php it's a useful tool for any 3D head, and a great file translation program, and useful for creation of objects for your Bryce scenes. If Corel lowered the upgrade price I would buy Bryce 5 in a second, but at a $159 upgrade price their not doing us a big favor, LOWER THE UPGRADE PRICE COREL! $159 IS TOO MUCH$$$$$$
