Well, Bryce allows you to render any size you want to disk. I just tried (never do that otherwise) and it accepted 12 thousand by nine thousand pixels at 600 dpi, that is, 20 by 15 inches. You control the aspect ratio in Document setup, where you can constrain it, or leave it free-floating. Rendering to screen is limited to 72 dpi. Bryce can also render over network with the supplied network client. BTW, as I've said elsewhere, Bryce is quite easy to master, but difficult to be master in. There's more to Bryce than chrome spheres over water (Bryce equivalent of Vicky in a temple.) So, for the best results, be prepared to spend a lot of time in Bryce. But I think it's the same for any program. Except possibly for 3D Studio, where you have to spend a lot of time just to start getting something useful. :-) Anyway, you should take a look at the galleries.
