Is there a limit to render size, other than what your hardware could handle? I am being asked if we could render a scene to go on a trade show banner that's somewhere in the 91" x 186" range. Manufacturer wants 200 dpi, so if my math is right, that's somewhere in the 37K x 18K pixel range rendered at 72 dpi to give me the pixels to do that. Is that even possible? If I use a cloud service is that the way to go, or do you sit there and render regions and assemble in Photoshop? I'm guessing it's too risky to do it on my machine and risk that 20 hours into a render it crashes and I start all over. Any thoughts would be much appreciated.

I have produced many printed banners, including several times bigger than 91 by 186 inches.
In almost all such cases, for banners the size you mention, it is just silly to use 200 dpi. You ought to be able to safely go down to 50 dpi, perhaps lower. Remember that people tend look at banners from a much larger viewing distance than your standard 300 dpi leaflet. Use the time and resources to make a great general design instead.
If you want to be sure, try rendering for 50 dpi, print a small excerpt, put it at the intended viewing distance of the banner, and see what it looks like. -
Largest render I rendered using V-Ray was 72K, so it works...question is, if it's really necessary. Best way to prevent crashes is using standalone and disable the framebuffer for renderingComment
