I've been making 30"x24" posters of some of my Bryce creations. To print at 300 dpi, I need a resolution of 9000x7200. I can do this if I render to disk, but then that ties up my PC during a very long render. I thought I'd do a Document Setup with a resolution of 9000x7200 and then send the .br5 file to a render farm, but the Document Setup dialog won't allow me to input a resolution that high. It keeps changing my 9000 to 4000. Any ideas?
