This step could be done centrally, or by someone else, so you might ask around to find out if there is a render-server (a computer that does renderings for you) already set up. It calls this 'distributed rendering' but lots of folks just call it 'using a render farm'. V-Ray has the ability to perform this 'distributed rendering' if you know what you're doing. It takes less time if the job is split up amongst several computers, or done on one superfast computer.
