To do a really big render you can with a bit of math and a bit of planning you can actually do tile rendering in Vue right now one square at a time what you need to know is the exact focal length cause 18 mm is exactly 90 degress FOV. So ie: Say i want to render a picture 1000 X 1000 at 90 fov but my computer is trash and can't handle it. Tile rendering without the support. Ok say I got my scene and it just happens to be set so the camera is pointing south 0 degrees and it's sitting level so it's sitting at 90 pitch. I can't render this impossible size so I figure that i'll do 4 500 X 500 renders than paste em all back together when it's finnished. So set the camera first to 32 mm which is now 45 degrees FOV tile upper right 135 pitch and roll -45 render then 135 pitch roll 45 then the bottom two are 45 pitch 45 roll, and finally 45 pitch -45 roll. See easy and you could split that up across 4 computers to get the job done in 1/4 of the time ! Hun can a borrow your computer for a few days? ! D'oh !
