Oh, ok! I thought that I might have misread it. I unfortunately don’t have an answer to that scenario.
But it seems interesting. I might try to look around and see if I find anything about it.
EDIT: after a quick search I found this video: https://www.youtube.com/watch?v=mFSq0nUl-0Y
Basically, you go to Scene properties and activate Stereoscopy. There should be an option for multi-view.
Add cameras in the menu and give them a suffix, then add the suffix to the cameras.
To render an animation like this, you might have to render as PNG.
EDIT 2: I also found this addon that seems to have support for animations: https://extensions.blender.org/add-ons/multiple-camera-render/

I remember when Shadow of Mordor released and they added the 4k dlc. I think that the dlc alone took up as much space, if not more than the whole game did without it.
Iirc it was about 60GB or something, might have been smaller as it’s an old game, but still huge.
