I'm in a bit of a fun spot where I have full access to a VR arcade and a couple dozen GPU's inside it. Each of the computers is running Windows 10 and is on their own high speed internal LAN with a NAS. In my spare time, I've been dabbling with small Blender animations as a hobby and wanted to utilize the processing power of the arcade at night to speed up render times. So my question is, how would I best go about doing that from outside of the network, without installing anything that would disrupt the regular operation of the arcade?
It's worth noting I can turn on/off the computers remotely, but not dual-boot into Linux remotely. I can also VNC into the individual computers, but I'd rather things be automated than have to start blender or some other other software on each computer each time I want to render something.
I've tried several solutions, including a Flamenco server, using third party plugins like CrowdRender, Prism pipeline's Pandora, etc. But they're all way over-complicated or only work on local networks. I ended up finding myself sinking more time into setting up the distributed rendering than I did actually animating, and gave up for a while.
Instead of trial and error or reinventing the wheel, I figured someone here would have experience with something similar or be able to suggest software that'd help out, or suggest I retry certain software I've already tried before.
