Thanks everyone for all the input. It has been most helpful. I've checked the task manager on XP and it say's that I'm using about 680 megs (PF) so I'm definatly running off the hard disk when it comes to memory. I could probably be more efficiant with my object creation in Bryce as by the time I scale the scenes and render the entire image at about 1152 x 768, I've noticed that most of the detail on smaller objects gets lost. Can Bryce be set up like Photo shop to have scratch discs? and I would be very interested in Ramidle as well? For the moment I will keep diving to the depths as my P4 sub with 512 megs of ram hasn't fully threatened to implode yet, although Win XP has on several ocasions told me that it has had to increase the virtual memory so that it wouldn't spring a leak. Once again, thanks folks for all your contributions.

Dave (and hopefully I'll get this bloody picture finished one day soon)
