RE: Animation and 3D modeling Flame IMP // Splinterlands Art Contest Week 184!

The render farms? Basically a bunch of networked computers (how they're networked depends on which render farm you're using, I think the normal paid ones are in data centres, and the ones like sheepit and burp which I don't know if it's still running as it had stalled violently last I checked are distributed) that you send your animation to and each computer involved in your project renders out at least a frame (or bunch of frames, I'm not 100% on the details). At the end something packages all the rendered frames back together nicely for you.
