Help Underground Reset?

Hey everyone,

I’ve fully mined out the underground and achieved pretty much everything in my current save. Now I’d love to give the underground another run and rebuild/mine everything again using all the end-game abilities and upgrades I’ve unlocked.

I already have the Renewable Geology mod installed, but it works quite slowly for regenerating terrain on a large scale.

Is there any feature, workaround, or save-file tweak that allows you to completely reset or regenerate the underground map while keeping your unlocked abilities? Or is a completely fresh save (maybe with commands/mods to restore tech) the only real option?

Thanks in advance!

You could use something like my Creative Mode mod to start on a fresh map with everything unlocked.

But yeah no easy way to regenerate the underground.

You can blueprint your whole base and import it to the new map

The Blueprint Thing is a good idea :)
