Sorry I missed this--Steam doesn't notify me when people post new discussions here.

The randomizer generates layouts and modifies regions on the fly as they're loaded, so there's no output file. But if you want to see the generated layout for the region you're currently in, the dev tools minimap should work.

If you're unfamiliar, Dev Tools needs to be enabled in the Remix menu, and then while you're in game, you press O to enable, H to show the interface, and then click on Map to show the map layout.
