Hey If your Kinetic Sculptures are anything to go by, your Nautilus will be fantastic! I did a VERY simple internal of the Nautilus (based on an external model I found somewhere) as in my gallery,,, See! It's really Poo! Please post an image! We'd love to see it! Bryce4 cannot use both processors on a dual system but Bryce 5 CAN. The network rendering capabilities can use the second processor as a 'slave' machine.
