Dedicated Server - map-gen-settings for other planets

I'm trying to get the steam dedicated server to modify other planet's resource generation.

I've dug through a dozens of posts here and on the subreddit, but I can't seem to get a map-gen-settings.json to modify any other planet's resources, they always revert to the default.

A few post mentioned that the autoplace_controls may not work for other planets, others had them have different names (vulcanus_coal) to be recognized appropriately. My only problem is, None of these seem to work for me.

I've dug through the wiki, and other forum posts, but I can't seem to figure out it, and my friends and I really want to have a save that modifies the resources on other planets.

Does anyone have a link to guide or post that actually explains how to do this on a dedicated server?

You can use Factorio Exchange String Converter (Github Source) to convert from the "Export" button of the New Game dialog (in the bottom-right corner) into a suitable map-gen-settings.json file.

Or, generate the initial Map locally and Upload the savegame.zip to the server.


Good Luck!
