OK, so due to a poor choice of engine, I'm using spritesheets in my game. Lots and lots and lots of them, in fact. These are rendered from 3D files in Maya into individual .png frames and then are put together into 2D spritesheets manually. The workflow took a bit of time to sort out, but it's fine now - we've got batch renders set up and all seems to be functioning well. The major obstacle we're now facing is time. We've got over a million frames of animation to render and my PC isn't really up to doing it inside of a year. I'm looking at renting time on a render farm to do the work in a couple of weeks - I was just wondering if anyone had any experience using render farms and any tips or recommendations where they are concerned?
