Okay, so I have to chime in… I’ve had great success with the watch folder, or setting up individual machines to render, but… it’s just me I have to deal with, so I don’t have to worry about fonts missing, etc. I have 7 machines, 1 that I usually sit at and work, and run the others through VNC including the 2 Macs. 3 of the PCs are complete dogs by current standards, but when the tension is high, they’re all on board, even the ones that render S-L-O-W-L-Y compared to my primary machine. I have it set up so that 1 mac (an old G3) is the server, and I’ll set my primary workstation to be part of the render team as well if it looks tight. The issue? Plugins. Fonts aren’t a problem, even if both Macs are working on it, as it’s easy to convert and share those. Plugins are limited by licensing restriction, as well as most not allowing installation on another network machine. I have my second fastest machine loaded with almost all the same plugins, so it frequently renders alone, or with my primary.
Here’s the deal – machines are cheap. Even though new machines are cheap, I started out with a bank (used to have 12) from my state’s surplus sales (which came with Win2k), which were all below 50 bucks a piece, and have each paid a mortgage payment for their work. When I need them, I walk by, hit the power button to turn them on, and they automatically look for the watch folder and go to work. No, and I mean -NO- hassle. If I had a partner again, it probably wouldn’t be so easy. Over time, I put Ubuntu on some of the oldest machines, and gave them to people that needed them. I’d be hard pressed to buy a new machine just as a render unit, but I’m a tightwad.
