Version and installation
- Check that your game build is 1.61.2.0s, the version specified for this package.
- Extract the downloaded archive.
- Copy the extracted files into the American Truck Simulator installation folder and replace the corresponding files, following the original post's instructions.
The installation folder is the game's root directory, rather than its Documents save folder. Keep a copy of the original files before replacing them so you can restore your installation if needed.
Separately, SCS Software's official 1.61 update adds new cargo types and brings its improved material system to the International LT and International LoneStar. See the official 1.61 release notes for the update details.
