Well I was able to set one up at 20 inches by 20 inches under the "render dimensions" but haven't had time to try to render it, it could take a long time at that size and 300dpi, I rendered a 600dpi at 6 x 9 inches yesterday and that took 5 hours!

I gotta say I wasn't aware of any inhibiting size except for the window size in your workspace, I always thought you could render any size as long as you had the guts in your machine to do it!

I will try this size tomorrow at a low dpi setting to see.

Have you tried the "render dimensions" setting as a matter of interest???

Injustice will be avenged.
