No you can render that size but when you render to disk it sorta forgets about the screen and just think it or it could take hours just to do a single line at a really huge size so it will also take hours to update the screen so it appears dead when it's hard painting your picture.Best way is to use two computers one that you can walk away from and one to use in the mean time. That's how I did mine. I've rendered bigger. You want to look at last years renderosity magazine contest threads that should be here on this form somewhere. There is a whole ton of threads there about rendering big pictures and the problems with it. See all the submissions needed to be also done print size that was the killer. Ya sure it might say 3 hours but it will take another 10 hours to do the antialasing pass and that don't show up on the counter. I just finnished one it said 3 hour 45 mins and it took a total of 17 hours to finnish completly and if you got any glow it will do two more passes after all of that that totally seems that Vue is locked up cause it don't update the screen at all on those passes till it's completly finnished. We need tile rendering and that's as simple as that. All of those problems would vanish, Hopefully it's in the next version cause it has been suggested. It's stupid trying to render a big picture all at once. Computers can hardly handle it and if anything goes wrong you got nothing to show for it. If you where tile rendering you'd only have to do the tiles over again that got munched. Mojoworld has tile rendering in version 2 but I suggested that for Vue way before that program came out. Like last year already during that contest.
