The short answer
Stop the server, install the mod from the Steam Workshop installer in your control panel,
then restart and allow 10 to 15 minutes for the download. If the Workshop installer will
not fetch the mod, subscribe to it in-game, zip the mod folder and its .mod
file from ShooterGame\Content\Mods\, upload both, and add the ID to
ActiveMods=.
Key points
- Always stop the server first. Installing onto a running server corrupts files.
- A long pause on first boot is the mod download, not a hang. Wait it out.
- Mod order in ActiveMods matters. The first entry wins any conflict.
- Total conversions run alone. They cannot be stacked with other mods.
- Removing a mod deletes anything built with its items. There is no salvage.
Which method you need
The three methods are not alternatives you pick by taste. They are a ladder you climb only as far as you need to.
- Method 1: Workshop installer
- Start here. Works for the large majority of mods and needs no file handling at all.
- Method 2: ActiveMods
- Use when you would rather have the server fetch mods itself on restart, or when you are editing configs anyway.
- Method 3: manual upload
- The fallback for mods the Workshop installer cannot download. More work, but it always works, because you are supplying the files yourself.
Method 1: the Steam Workshop installer
-
Stop your server
Always turn the server off before installing mods. Writing mod files underneath a running server is how you get a corrupt install rather than a working one.
-
Open the Steam Workshop installer
It is in your server's control panel. This is the tool that talks to the Workshop on your behalf.
-
Search for and download the mods you want
Filter for the mod by name or ID, then click Download on each one you want installed.
-
Restart and let it finish
The server will pause while it unpacks. This is the stage people mistake for a crash.
To deactivate a mod later, either click Uninstall in the Workshop installer,
or edit GameUserSettings.ini and remove that mod ID from the
ActiveMods= line.
Method 2: the ActiveMods method
This approach hands the mod list to the server directly and lets it manage the downloads on restart.
-
Add the mod IDs to ActiveMods
Open
GameUserSettings.iniand put the IDs on theActiveModsline, comma separated with no spaces.ActiveMods=439927654,342653673 -
Restart your server
The server pauses temporarily, typically 10 to 15 minutes, while it downloads the mods you listed. Leave it alone during this window.
A server sitting at around 54MB of RAM during startup is downloading mods, not stuck. Restarting it here throws away the partial download and starts again from nothing, which is why the "it never finishes" reports almost always come from people who restarted twice.
Method 3: manual upload for mods that will not download
Some mods will not come down through the Workshop installer. When that happens you fetch the files with your own game client and upload them yourself.
Getting the mod files
-
Subscribe to the mod on Steam
Find it in the Steam Workshop and subscribe as you would for single player.
-
Launch ARK to the main menu, then close it
Reaching the main menu is what makes the client install and unpack the mod. You do not need to load a world.
-
Locate the files and zip them together
Go to:
Steam\steamapps\common\ARK\ShooterGame\Content\Mods\You are looking for a folder named after the mod ID, for example
46754636, and a matching.modfile beside it. Zip both together. Missing the.modfile is the single most common reason a manual install does not work.
Uploading to your server
-
Turn the server off
Log in to your control panel and stop the service before touching any files.
-
Upload the ZIP into the Mods folder
In the file manager, navigate to
ShooterGame\Content\Modsand upload your archive there. -
Extract it and check the structure
Unzip in place, then confirm the result looks like this, with the mod ID as a folder directly inside
Mods:ShooterGame\Content\Mods\439927654A common mistake is extracting one level too deep, leaving
Mods\myzip\439927654, which the server will not find. -
Activate the mod
Open
GameUserSettings.iniand add the ID to theActiveMods=line.ActiveMods=439927654,342653673 -
Restart the server
Startup will take longer than usual while the mods load. That is expected.
Stacking multiple mods
To run several mods together, list their IDs on the same line separated by commas:
ActiveMods=439927654,342653673,567893421
Order is not cosmetic. The mod at the top of the list takes priority, and the ones after it add items or override settings where they overlap. If two mods both change the same creature or recipe, the first one listed is the one that wins.
Test the combination before you put it in front of your players. A stack that loads is not the same as a stack that behaves, and conflicts often only surface once someone tries to craft the thing both mods touched.
Total conversion mods
A total conversion replaces the game rather than extending it, so it is loaded through its
own parameter rather than through ActiveMods.
-
Upload the mod
Use the manual upload method above to get the files onto the server.
-
Activate it in the command line manager
Create a new command line with the argument:
-TotalConversionMod=547377246Then set the map to
TheIsland, or whichever map the conversion expects. -
Save and restart
The conversion loads on boot in place of the standard game.
Do not leave -TotalConversionMod= in your command line pointed at a mod that
is not a total conversion. It is a leading cause of servers that reset their player slot
count and mods that refuse to load. If you are not running one, remove the parameter.
Map mods
-
Upload the map mod
Manual upload method again, same as above.
-
Set it in the command line manager
Choose the Custom Map option. Put the mod's map name in the first box and its ID in the second.
-
Save and restart
First boot on a new map takes noticeably longer while the world generates.
When mods will not load
- Server crashes on boot
- Usually a mod ID in
ActiveModswhose files are not actually present, or two mods that conflict. Remove the most recently added ID and restart to confirm which. - Mod appears installed but does nothing
- Check the ID is on the
ActiveModsline and not just downloaded. Downloading and activating are two separate steps. - Startup never finishes
- Almost always a mod download still in progress. Give it the full 15 minutes before intervening.
- Mod worked, then broke after a game update
- The mod needs updating for the new game version. Check the Workshop page for the mod's own update status rather than reinstalling it repeatedly.
Habits that save time:
- Back up your configuration files before changing them, so reverting is a copy and paste rather than a rebuild.
- Read the mod's own Workshop description for compatibility notes before you install. Most conflicts are documented there.
- Watch performance as you add mods. Load times and server strain both climb with the number of mods, and the point where it stops being worth it arrives sooner than most people expect.
