Also Bryce is not OS-centric, so on a DP Mac just make a copy of the Bryce folder and run one Bryce doing half of the render and the other Bryce doing the other half. Then stick the 2 halves together in photowhatever. I use this all the time on my DP Mac and runs just as fast as if it supported DP. Bryce is remarkable stable under OSX, especially since the OSX version hasn't been updated since 10.1. The only real crashes I've had have been the .MTL problem mentioned above. Since 10.2 I've been unable to use the network render system as host or client and sometimes Bryce's menu grays out and the key commands stop working which requires a force quit. Both this may be DP issues. At the price it's being offered I think it's a real good deal for Mac users. I think you also get the OS9 and PC versions (DAZ may have changed this). HTH; Dan
