I purchased Bryce 5 this weekend and must say I am a bit dissapointed. The rendering times are longer, no doubt. Also they claim that the speed of Bryce in Mac OSX is the same as in OS9. This is a blatent lie. I rendered a scene in OS9 that took 46.14 min, I then rendered the same seen using OSX and it took 57.30 min. This is a HUGE difference, I tried this comparison with a few scenes and received similar results. I am running a G4 450DP with 768MB RAM. It is much slower in OSX. Not to mention the interface completely dissapears from time to time, forcing you to minimize then maximize the screen to get it back. I bought this update mainly for OSX comapt and Network rendering. Now the net rendering does work, but it only works on an Animation, not on a still. They also removed several of the primtives, and to make these same shapes now requires more work. (Unless they hid them somewhere, but I don't see them.) I will probably keep using 4 until a patch is released to fix some of these issues. As for the comments about Kaom being on a vandetta, or is a spammer, this is crap! I don't know kaom personally but he has been nothing but helpfull in the Carrara forum and I enjoy his insight and comments, he has helped me numerous times, including a purchase decision. I agree with him, Corel has a long way to go. And for me, a mac user, they have been pathetic. Hell even the Licence code that they sent with Bryce 5 Upgrade does not work correctly, you have to call and get a generic one from their underly friendly customer support. Don't even get me started on all the bugs in Corel Draw 8, which for Mac users is the latest version, 10 was supposed to be out by now, and you have all the reason in the world to gripe about Corel. I am really glad that they did not buy Carrara, as Eovia has done an excellent job with that!
