Step 1 — Install / enable your mods in ATS

Open American Truck Simulator on your PC.

From the main menu, go to:

Mod Manager

Install/select the mods you want from Steam Workshop, then move them into the Active Mods list.

Make sure the load order is how you want it.

Then click confirm/apply and load into single player once.

Step 2 — Check your DLCs

From the ATS main menu, open:

DLC Browser

Make sure any DLCs you want the server to use are installed and enabled on your client.

This matters because the exported package files include information about your active DLCs and mods. (Zap-Hosting)

Step 3 — Enable the developer console

Close the game first.

Go to this folder on your PC:

C:\Users\YOUR_WINDOWS_USER\Documents\American Truck Simulator

Open:

config.cfg

Find this line:

uset g_developer "0"

Change it to:

uset g_developer "1"

Then find:

uset g_console "0"

Change it to:

uset g_console "1"

Save the file.

Step 4 — Export the server packages

Open ATS again.

Load into the game with your mods active.

Open the console using one of these keys:

` 
~
\

The correct key depends on your keyboard layout.

In the console, type:

export_server_packages

Press Enter.

ATS should now create these two files in your Documents ATS folder:

C:\Users\YOUR_WINDOWS_USER\Documents\American Truck Simulator\server_packages.dat
C:\Users\YOUR_WINDOWS_USER\Documents\American Truck Simulator\server_packages.sii

Step 5 — Upload the files to your ATS server

Connect to your server files using FTP/SFTP or your panel’s file manager.

Go to the main/root ATS server directory.

Upload these two files:

server_packages.dat
server_packages.sii

If they already exist, replace them.

The files should sit in the main ATS server folder, not inside a random subfolder.

Step 6 — Restart the server

Restart the ATS server.

The server should now load with the mods/DLC setup from your exported package files.

Important notes

Players need the same required mods to join. If they do not have the mods installed, ATS should prompt them to download the missing Workshop mods.

If you change mods later, you need to repeat the process:

Enable/change mods in ATS
Export server packages again
Upload the new server_packages.dat and server_packages.sii
Restart server
