Installing DayZ Mods

Installing DayZ Mods

DayZ mods extend your game with new weapons, vehicles, helicopters, maps and entire mechanics. RespawnHost integrates the Steam Workshop directly into the panel — no manual file operations needed.

How DayZ Mods Work Technically

A DayZ mod is an @ModName folder in the server root. The server loads it via the start parameter -mod=@Mod1;@Mod2. So clients can use the mod without signature errors, the .bikey from the mod’s keys/ subfolder must also be copied to the server’s keys folder.

RespawnHost automates all three steps (download, start parameter, key copy).

Install a Mod via the Panel

1. Open your DayZ server in the RespawnHost panel
2. Pick the Steam Workshop tab
3. Enter the mod ID from the workshop URL
4. Click “Add”
5. Restart — the mod is downloaded on boot, the key is copied, and the start parameter is updated

Finding the workshop ID:

It’s the number in the workshop URL. Example: https://steamcommunity.com/sharedfiles/filedetails/?id=2116151222 — the ID is 2116151222.

Server-only Mods (-serverMod)

Some mods (admin tools, RCon helpers) should only run on the server, not on clients. Those are loaded via -serverMod=@AdminMod instead of -mod=. In the RespawnHost panel you can flag any mod as a Server mod when adding it.

Typical server-only mods:

• VPP-Admin Tools (server side)
• ZomBerry Admin Tools (server side)
• CF (Community Framework, dependency)

Client Mods vs. Mission Mods

DayZ has two main mod types:

• Client mods (-mod=) — players also need the mod subscribed in their DayZ Launcher. Examples: DayZ Expansion, Trader, MuchStuffPack.
• Server-only mods (-serverMod=) — players don’t need it. Examples: admin tools, BattlEye extensions.

When joining, the DayZ Launcher auto-downloads any missing client mods from the Workshop.

Note: workshop IDs don’t change. The mods themselves do, however — always check the workshop page to make sure a mod is still maintained before going live.

Load Order

The order in your -mod= parameter matters. Rule of thumb:

1. Frameworks first (@CF, @DabsFramework)
2. Core mods (@DayZ-Expansion-Core)
3. Extensions that depend on core
4. Map mods near the end
5. Visual / cosmetic last

In the RespawnHost panel you can drag-and-drop to reorder.

Updating Mods

RespawnHost checks for new workshop versions on every server start and downloads automatically. You don’t need to do anything — a restart is enough.

If a mod update breaks a dependency, you can disable the mod temporarily without removing it.

Detecting Mod Conflicts

Symptoms:

• Server crashes immediately on startup
• Players are kicked with “Session Lost”
• Items don’t spawn or inventories stay empty
• Script errors in script.log

Workflow:

1. Open profiles/script.log in the file manager
2. Search for ERROR: or Cannot find class
3. The class or mod name usually identifies the offender
4. Disable the mod and restart

Integrating Mod Types.xml

Many mods (Expansion, MuchStuffPack, BaseBuildingPlus) ship custom items. For them to spawn, you need to add their items to your types.xml. Mods provide template files like:

@DayZ-Expansion-Core/scripts/4_World/Classes/Inventory/expansion_types.xml

Copy the relevant <type> blocks into your mpmissions/dayzOffline.chernarusplus/db/types.xml. Details under Central Economy.

FAQ

Question: Do players have to install mods themselves?

For -mod= (client mods): the DayZ Launcher auto-downloads them on join. For -serverMod=: players don’t need anything — the mod runs server-side only.

Question: Where do I find the workshop ID?

In the workshop URL after ?id=, the numeric portion. You can also click “Mod Details” in the DayZ Launcher to see the ID.

Question: My server crashes after a mod update — what now?

1. Open profiles/script.log
2. Find the first ERROR: line
3. Disable that mod or wait for a patch
4. If you have a backup strategy, roll back to an earlier version (see Backups)

Question: How do I install DayZ Expansion?

Three ways: the Bundle (workshop ID 2572331007) pulls all modules at once. Alternatively, install individual modules for a leaner setup. Either way, @CF and @DabsFramework are required dependencies. Don’t forget to set the Expansion mission files (expansion.chernarusplus) as your mission if you want the full Expansion experience.

Question: How many mods is too many?

There’s no hard limit. In practice, server FPS and RAM degrade after ~30-40 large mods. Most communities run fine with 10-20 well-chosen mods.

Question: What’s the difference between mod folder and workshop subscription?

The DayZ Launcher caches downloaded mods centrally and symlinks them into the game. On the server, the mod lives as a real @ModName folder. RespawnHost downloads directly from the workshop and stores the mod permanently — no Steam login on the server.

Question: Do I need BattlEye filters for mods?

Some mods fail strict BattlEye filters (scripts.txt, setvariable.txt, addmagazinecargo.txt, etc.). The mod’s workshop description usually lists required filter exceptions. Filters live in battleye/.

Question: I want to test a mod without public players — possible?

Yes. Set password = "test"; in serverDZ.cfg. Only people with the password can join, so you can test mod updates safely.
