Server Configuration Export

PZ Packs generates server configuration files that you can directly use with your Project Zomboid dedicated server. The export system handles mod IDs, workshop items, and map folders automatically based on your modpack configuration.

​
Overview

The server file export feature generates configuration snippets compatible with Project Zomboid server INI files. These files contain the properly formatted mod lists, workshop IDs, and map configurations needed to run your modpack on a server.

Build Support

Export files for both Build 41.x and Build 42.x with correct formatting for each version.

Custom Configuration

Save personalized export configurations including mod order and selected Steam Mod IDs.

Background Processing

Large exports are processed in the background, allowing you to continue working.

Direct Download

Download ready-to-use configuration files that can be copied into your server settings.

​
Export Configuration Options

Before exporting, you can configure how your modpack is exported.

​
Build Version Selection

Project Zomboid Build 41.x and 42.x use different mod ID formats:
Modern Format (recommended for new servers)
  • Mod IDs are prefixed with a backslash: \ModID
  • Format: Mods=\ModID1;\ModID2;\ModID3
This is the current stable format for Build 42 and later.
Using the wrong build format will prevent mods from loading on your server. Always select the version matching your Project Zomboid server.

​
Mod Order Configuration

The order of mods in the export file affects how they load on the server:
  1. Navigate to your modpack details page
  2. Click “Reorder & Configure Export”
  3. Arrange mods in the desired load order
  4. Save the configuration
Export configurations are saved per user. This allows team members to maintain their own preferred export settings while working on the same modpack.

​
Steam Mod ID Selection

Mods with multiple Steam Mod IDs allow you to select which components to include:
1

Open Configuration Interface

Click “Reorder & Configure Export” from the modpack page.
2

Review Mods with Multiple IDs

Mods with multiple Steam Mod IDs will show checkboxes for each component.
3

Select Components

Check or uncheck Steam Mod IDs to include/exclude specific components.
4

Save Configuration

Click “Save” to persist your selections.
If you deselect all Steam Mod IDs for a mod, that mod will be completely excluded from the export file.

​
Requesting a Server File Export

Generate a server configuration file for your modpack.
1

Navigate to Your Modpack

Open the modpack details page for the modpack you want to export.
2

Click Export

Click the “Export” or “Export Server File” button.
3

Select Build Version

Choose between:
  • Build 42.x (modern format with backslash prefix)
  • Build 41.x (legacy format)
4

Request Generation

Click “Export” to create the server file. The system will:
  • Queue the export job
  • Process your modpack’s mods in the configured order
  • Apply your saved export configuration
  • Generate the formatted configuration file
5

Monitor Status

The export request status will show:
  • Pending: Being processed
  • Completed: Ready to download
  • Failed: An error occurred

​
Export Processing

The export generation process:
  1. Fetches Mod List: Retrieves all mods in your modpack
  2. Applies Configuration: Uses your saved export configuration (or defaults)
  3. Sorts Mods: Orders mods according to your specified sequence
  4. Filters Components: Includes only selected Steam Mod IDs
  5. Formats Output: Generates the server configuration in the correct format
  6. Saves Export: Stores the file content for download
Export jobs are processed in the background. For large modpacks (50+ mods), this may take 10-30 seconds.

​
Downloading the Server File

Once the export is complete, download the configuration file.

​
Download Process

  1. After the export completes, a download button or link appears
  2. Click “Download” to get the server configuration file
  3. The file is downloaded with a descriptive name (e.g., modpack-name-42x.ini)

​
File Format

The downloaded file is a plain text file containing three main lines: 
Mods=\ModID1;\ModID2;\ModID3;\ModID4
Map=Muldraugh, KY;CustomMap1;CustomMap2
WorkshopItems=2876012699;2876012700;2876012701
Format: Mods=<semicolon-separated list>Contains Steam Mod IDs for all selected mod components:
  • Build 42.x: IDs prefixed with \ (e.g., \ModID)
  • Build 41.x: IDs without prefix (e.g., ModID)
Example:
Mods=\ModID1;\ModID2;\ModID3
Format: Map=<semicolon-separated list>Contains map folders from mods plus the default map:
  • Always includes Muldraugh, KY as the default
  • Appends custom map folders from mods
Example:
Map=Muldraugh, KY;CustomMapName;AnotherMap
Format: WorkshopItems=<semicolon-separated list>Contains Steam Workshop IDs for all mods:
  • One Workshop ID per mod
  • Used by Steam to download mods to the server
Example:
WorkshopItems=2876012699;2876012700;2876012701

​
Using the Server File

Integrate the exported configuration into your Project Zomboid server.

​
Server Configuration Steps

1

Locate Server INI File

Find your server’s configuration file:
  • Windows: Zomboid/Server/<servername>.ini
  • Linux: ~/.steam/steam/steamapps/common/Project Zomboid Dedicated Server/Zomboid/Server/<servername>.ini
2

Open Configuration File

Open the .ini file in a text editor.
3

Find Mod Configuration Section

Locate the existing Mods=, Map=, and WorkshopItems= lines in the file.
4

Replace with Exported Content

Copy the three lines from your downloaded file and replace the corresponding lines in the server INI.
5

Save and Restart

  • Save the INI file
  • Restart your Project Zomboid server
  • Steam will download any missing mods
  • Server will load with your modpack configuration
Backup your server configuration before making changes. Keep a copy of your original Mods=, Map=, and WorkshopItems= lines in case you need to rollback.

​
Troubleshooting Server Configuration

Possible causes:
  • Wrong build version selected (41.x vs 42.x format mismatch)
  • Invalid Steam Workshop IDs
  • Mods not downloaded by Steam yet
Solutions:
  • Verify build version matches your server
  • Check server console for mod loading errors
  • Wait for Steam to download all Workshop items
  • Ensure Workshop IDs are correct in PZ Packs database
Possible causes:
  • Map folder names incorrect
  • Mods with maps not properly configured
Solutions:
  • Verify map folder names in mod details
  • Check that map mods are included in the Workshop items list
  • Review mod descriptions for special map configuration requirements
Possible causes:
  • Mod conflicts
  • Incompatible mod versions
  • Missing mod dependencies
Solutions:
  • Check server console logs for error messages
  • Test mods in small groups to isolate conflicts
  • Verify all required dependencies are in the modpack
  • Try a different mod load order

​
Export Configuration Storage

PZ Packs stores export configurations separately from modpack metadata.

​
Per-User Configurations

Each user can save their own export configuration: 
{
  "modpackId": "uuid-of-modpack",
  "userId": "uuid-of-user",
  "modsOrder": ["mod1-uuid", "mod2-uuid"],
  "modConfig": {
    "mod1-uuid": {
      "selectedSteamModIds": ["ModID1", "ModID2"]
    }
  }
}

​
Fallback to Modpack Defaults

If a user hasn’t saved a custom export configuration:
  • The system uses the modpack’s default metadata
  • Modpack owner’s configuration is stored in the modpack metadata
  • All Steam Mod IDs are selected by default
This allows team members to work on the same modpack while maintaining different export preferences (e.g., different mod orders for testing purposes).

​
Export History

PZ Packs tracks all export requests for audit and debugging purposes.

​
Stored Information

Each export record includes:
  • Export ID: Unique identifier
  • Modpack ID: Which modpack was exported
  • User ID: Who requested the export
  • Version: Build version (41.x or 42.x)
  • Status: Pending, completed, or failed
  • File Content: The generated configuration text
  • Timestamps: Created and updated times
Export history is not currently displayed in the UI but is stored in the database for administrative purposes.

​
Best Practices

  • Review and test your mod load order
  • Verify all mods are compatible with your target build version
  • Check that required dependencies are included
  • Save your export configuration before requesting a file
  • Always backup your existing server configuration
  • Test the modpack in single-player before deploying to a live server
  • Deploy during low-traffic periods
  • Have a rollback plan ready
  • Monitor server logs during the first startup
  • Re-export after adding or removing mods
  • Update exports when mod versions change significantly
  • Keep a copy of working configurations
  • Document any custom tweaks made outside of PZ Packs
  • Use separate modpacks for Build 41 and Build 42
  • Clearly label modpacks with the target build
  • Test after Project Zomboid updates
  • Verify mod compatibility when switching builds

​
Permissions

To export server files, you need the export permission on the modpack.
  • Owners: Have export permission by default
  • Members: Require the export permission to be granted
See Team Collaboration for details on permissions.
