How to Configure Sandbox Settings on Your Project Zomboid Server

In this guide, we will show you how to configure sandbox settings for your Project Zomboid server by editing the sandbox variables file.

Sandbox settings control various gameplay mechanics such as loot spawns, zombie behavior, zombie spawns, player stats, weather, and much more. These settings allow you to customize your server’s difficulty and gameplay experience.

Configuring Sandbox Settings

1. Access the Game Host Bros Panel and Stop your Project Zomboid server.
2. In the sidebar, click Files and navigate to .cache/Server/pzserver_SandboxVars.lua.
3. Edit the settings you want to change. Each setting has comments with their valid values.
4. Save the file and start your server.

Tip

Some changes will only take effect after a server restart.

Always make a backup of your pzserver_SandboxVars.lua file before making changes, so you can easily revert if needed.

Troubleshooting

If your changes aren’t applying make sure your changes are being saved, if the issue persists consider the following:

Caution

Invalid Values: Values may be invalid or formatted incorrectly. Double-check the sandbox file for the correct format and valid options listed for each setting.

Corrupted Files: Your save may be corrupted. Stop your server, go to File Manager, and delete the map_sand.bin file in your save folder located at .cache/Saves/Multiplayer/pzserver/map_sand.bin.

Mod Conflicts: There may be a mod-related issue, ensure that you don’t have any mods overriding specific sandbox settings.

Reset Your Server: If you need to start fresh, follow our guide to reset your Project Zomboid Server.
