Aye, there is one MAJOR benefit to rendering to disk. It auto-saves the render when it's done! This is handy for me on Bryce 4 at work, I tried it last night, and although my comptuer was off when I got to work, it had at least finished and saved the render! Of course, Bryce's batch process would do that too, but it's kinda silly, all that dragging and dropping... (glares)
