American Truck Simulator - Dedicated Server Multible Instances

If you want to launch a server with different configuration, use following startup parameters:

-homedir "set a home directory"
-server "server packages file name"
-server_cfg "server config file name"

Exemple for a none Single Server and homedir:

Exemple for a none Single Server, different server files and no homedir set:

No homedir means, the gameserver will use the default location, \Documents\American Truck Simulator.

You do not need to rename the server files if you set a -homedir. You can skip the next two steps.

Working directory: Documents - American Truck Simulator

Copy & Paste following:
server_config.sii
server_packages.dat
server_packages.sii

and rename it as you liking. In my case:
server_config_en.sii
server_packages_en.dat
server_packages_en.sii

Open up:
server_packages_en.sii

And edit line 14:
roads_data_file_name: "/home/server_packages.dat"
to
roads_data_file_name: "/home/server_packages_en.dat"

Save file.

Open up:
server_config_en.sii

And make your changes.

In some cases if you want to make a second server, the map data can be outdate depens when you created the server packages you surely can create fresh server packages without destination file.

Or you already using the default files, to don't override them you can choose a destination file.
