If you're looking to further customize your server outside of basic gameplay settings, modding is a fantastic way to do so. Here's how to install mods on your Project Zomboid Server.

Caution

Many mods have NOT been updated for B42 yet. Check each mod's Workshop page for B42 support before installing.

Note

Steam Workshop items are downloaded when the server starts, so changes apply after saving and restarting your server.

Using the Steam Workshop Installer Recommended

The easiest way to install mods is directly through the panel.

Caution

This installer does not automatically install dependencies. Check each mod's Workshop page for any required dependencies and install those separately.

1
Log in to Bropanel and select your Project Zomboid server.
2
In the sidebar, go to Mods and open the Browse tab.
3
Search for the mod you want and click Install.
4
Restart your server.

Getting Mod And Steam Workshop IDs

As an alternative, you can install mods manually by adding them to your server's config file. You will need to know how to get a Workshop ID and Mod ID for each mod you want to install. You can view all the Project Zomboid mods here

Once you find the mod you want you need to note the following. Let's use this mod for example: https://steamcommunity.com/sharedfiles/filedetails/?id=3378304610

PZ Workshop URL

As you can see from the details at the bottom of the Steam Workshop page, this mod's Workshop ID is 3378304610 with its Mod ID being RepairableWindows.

Manually Installing Mods

B42 is the current stable build of Project Zomboid, so use these steps unless your server runs an older build.

1
Log in to Bropanel and Stop your server.
2
In the sidebar, go to Files.
3
Navigate to .cache/Server/ and open pzserver.ini.
4
Set DoLuaChecksum=false.
5
Add the Workshop ID to WorkshopItems using semicolons:
WorkshopItems=3378304610;2849467715
6
Add the Mod ID to Mods using backslashes and semicolons:
Mods=\RepairableWindows;\WaterGoesBad
7
Click save and start your server.

The examples above use the mods RepairableWindows and Water Goes Bad.

Tip

To install multiple mods you must separate each Workshop ID and Mod ID with a semicolon, and on B42 each Mod ID needs a leading backslash, for example \RepairableWindows;\WaterGoesBad as seen above.

Installing Mods on B41 and Older Builds

If your server runs B41 or an older build, use these steps instead. Mod IDs do not use a leading backslash on older builds, and DoLuaChecksum can stay on its default setting.

1
Log in to Bropanel and Stop your server.
2
In the sidebar, go to Files.
3
Navigate to .cache/Server/ and open pzserver.ini.
4
Add the Workshop ID to WorkshopItems.
5
Add the Mod ID to Mods.
6
Once finished, click save and start your server.

Here's the same example on B41, with no backslashes in Mods:

WorkshopItems=3378304610;2849467715

Mods=RepairableWindows;WaterGoesBad
