Recomended Computer Specs

You are going to want to have the game running in the background and still continue working on the same machine with normal performance.

As a guideline I would recommend double the gamespecs. It’s probably possible to create mods with much less. But it’s a big game, and a big engine. All tiny improvements can add up fast.

Some Important Directories / Paths

Name Path Description
Game Path C:\Program Files (x86)\Steam\steamapps\common\Farming Simulator 25 The location where steam installs the game files.
XML Specs and Script Bindings C:\Program Files (x86)\Steam\steamapps\common\Farming Simulator 25\shared\xml Resources if you want to understand or interface with the xml/lua systems.
Example Maps C:\Program Files (x86)\Steam\steamapps\common\Farming Simulator 25\data\maps Base Game sample maps. The GE editor uses these files to create a new “Map from Mod”.
Placeables C:\Program Files (x86)\Steam\steamapps\common\Farming Simulator 25\data\placeables Most of the in-game objects are here. Both xml and i3d files.
Game AppData Path C:\Users\WINDOWSUSERNAME\Documents\My Games\FarmingSimulator2025 Location where the game stores all user-specific settings. Mods, save files, configs.
Mods Path C:\Users\WINDOWSUSERNAME\Documents\My Games\FarmingSimulator2025\FarmingSimulator2025\mods Adding or removing mod zip files or folders enables them for use in game.
Editor Path C:\Program Files\GIANTS Software\GIANTS_Editor_10.0.3 Installation location of the GE. Some editor-scripts are located here.
Editor AppData Path C:\Users\WINDOWSUSERNAME\AppData\Local\GIANTS Editor 64bit 10.0.3 User data location for GE

Visual Studio

An extensive IDE, mostly for C# projects. Not really necessary for FS modding. But it’s my personal prefered tool if I need to create some tool.

Download: https://visualstudio.microsoft.com/downloads/

Git / Gitlab / GitHub

Most of the Farming Simulator modding files are code-based xml and lua files which should be stored in a version-control system.

Git is the industry standard for storing and collaborating on code. And it’s your own protection against losing your own work.

Python / PIP

The maps4fs project is based on PIP, if you want to build the engine locally, running it with these python versions worked for me.

Download Python: https://www.python.org/downloads/windows/

Download PIP: https://pip.pypa.io/en/stable/installation/

Cpp SDK

Something in the maps4fs pip depends on it to build. I don’t remember exactly which sdk.

WSL2 / Ubuntu / Docker / Docker Desktop

Docker Desktop does most of the wsl setup itself, if you don’t want to the use the Ubuntu wsl yourself.

Dotnet 8 SDK

Installed with Visual Studio, used for some custom tooling.
