Abiotic Factor SandboxSettings.ini: Tuning Game Rules

Abiotic Factor's SandboxSettings.ini explained: correct path, the [SandboxSettings] header, when changes apply — and which mistake blocks world loading.

Where do I configure my Abiotic Factor server’s game rules?

All sandbox game rules of your server world live in exactly one file: the SandboxSettings.ini in the world folder. There is no “ServerSettings” or “Worldsettings” file — anyone looking for one is looking in vain. Changes only apply after a server restart.

The correct path

The file lives per world in the server’s save directory:

[Server]\AbioticFactor\Saved\SaveGames\Server\Worlds\[WorldName]\SandboxSettings.ini

[WorldName] is “Cascade” by default — or whatever your -WorldSaveName parameter says (see the setup guide). At RespawnHost you reach the file via the file manager in the panel or SFTP.

Note

Because the file sits inside the world folder, the settings apply per world. A new world (new -WorldSaveName) starts with fresh defaults. With -SandboxIniPath= you can alternatively point to a custom path.

File structure

All entries go under the [SandboxSettings] header:

[SandboxSettings]
; Setting=Value

The workflow for changes:

  1. Stop the server.
  2. Open SandboxSettings.ini in the file manager.
  3. Adjust values under [SandboxSettings] and save.
  4. Start the server — only now do the changes apply.

Warning

Invalid values block world loading. A typo or invalid value can stop the server from loading the world at all. Create a backup in the panel before editing — and change values one at a time instead of all at once.

Tip

The sandbox options mirror the settings you see when creating a co-op world in game. The easiest route: assemble the rules during world creation in game, then handle later fine-tuning via the INI.

Frequently asked questions

Why don’t my changes apply? SandboxSettings.ini is only read on world start — changes need a server restart. Also check that you edited the file of the correct world (correct -WorldSaveName folder).

My server won’t load the world after editing — what now? Very likely there’s an invalid value in the INI. Revert the last change or restore the backup. As a last resort: delete the file — the world then starts with default values.

Is there a ServerSettings.ini or Worldsettings.ini? No. The only file for sandbox game rules is SandboxSettings.ini in the world folder with the [SandboxSettings] header.
