To get started with modding Satisfactory, you’ll need multiple other pieces of software installed first.
Don’t worry, we’ll guide you through each step of downloading and installing these dependencies.
This can be a very lengthy process, so if you have to work on something else, make a note of where you left off so it’s easier to resume.
If you’d prefer a different format of guide, you can find a video guide here. As of SML 3.0.0, these tutorials are partially out of date, but many of the concepts will still carry over. If you get stuck in the video tutorials, return here and follow these guides instead. Be sure to read over the steps here as well to be sure you’re doing things correctly.
This one should be pretty straightforward, and odds are, you’ve already done it. Simply buy, download, and install Satisfactory from the Epic Games Launcher or Steam. Launch the game at least once to ensure all files get set up correctly.
Visit the Microsoft Visual Studio downloads page and download the version you want. We suggest either Visual Studio 2019 or 2017 Community, because they’re free of charge. It is important that if you use 2019 you still install the 2017 compilers.
Run the installer, and agree to prompts you receive along the way. Select the packages "C++ Desktop development" and "Game development with C++". You might have to scroll a bit to find them.
If you already have Visual Studio installed, you can run the installer again and choose
Modify to select these two packages and add them to your installation.
Continue through the rest of the prompts to install Visual Studio. Downloading and installing Visual Studio can take a while, so we advise you to find some lizard doggos to pet while you wait, or working on some of the other install steps below.
An alternative to visual studio which is very popular among C++ modders is Rider for Unreal Engine. If you consider using it, make sure you still have the necessary VS-C++ packages installed.
Because Satisfactory uses a modified version of Unreal Engine, we modders need to be using that same version as well to develop our mods.
You’ll need to register your GitHub account with Epic Games to be able to download this special version. Directions on how to do so can be found here.
If the page says, "Sorry, the service is temporarily unavailable. Please try back later." try turning off any adblockers or content filters you may have enabled and refreshing the page without cache (Ctrl+Shift+R).
You will probably have to check your email and confirm from there, as well as making sure you’re logged into your linked GitHub account when you follow the upcoming link.
Once you’ve done that, go to the Satisfactory Modding Unreal Engine project and download
UnrealEngine-CSS-Editor-Win64.exe, then run it to install the Unreal Engine editor for this custom version.
If you see a "404 This is not the web page you are looking for" error, then you didn’t finish linking your account. Check for emails from both Epic and GitHub, and be sure that you followed the above steps. The page is not dead, this is what GitHub displays as a security measure when someone tries to access a private repo.
This install process, and opening Unreal for the first time afterwards, can take some time. Don’t worry about opening unreal yet though. It will probably ask you to compile things you haven’t properly set up yet.
Once the installer is done, you’ll also need to install a visual studio extension shipped with the editor. Navigate to where you installed the editor, probably something like
C:\Program Files\Unreal Engine - CSS\, and then navigate to the folder
\Engine\Extras\UnrealVS\. Open the sub folder for the version of Visual Studio you have installed (probably 2019) and run the .vsix installer to install the Unreal visual studio extension, which will help with debugging.
Wwise is a sound engine used by Coffee Stain, and in order to develop mods, you’ll need to install and integrate Wwise with your mod project.
Visit Wwise.com and click on the
Get Wwise →
Download Wwise button in the upper right corner.
Click the download button, which will ask you to sign in.
Create an account if you don’t have one yet, or sign in, to download the launcher.
After you finished downloading Wwise, open the installer.
WWISE from the top bar, and select version
(you might need to change the left dropdown to
All to do this), then press
Once presented with options on what to install,
make sure that
SDK (C++) packages are checked on the left,
Visual Studio 2017
Visual Studio 2019 are selected, then press
You don’t need to add any plugins,
so just press
Install to skip in the bottom left to begin the installation process.
Accept any authentication prompts that appear along the way.
Make sure that you selected the correct version of Wwise. It’s easy to choose the wrong version on accident.
SML 3.0 Note: Get the sml-dev branch from here instead of using the link below (for now).
To get started developing your mod, it’s best to start off with the Starter Project as a base.
You can download it from here.
SML-Shipping-Dev-Win64.zip from the latest release version and unzip it.
The starter project itself is contained in
and this download contains the SML-related plugins already loaded.
If you are familiar with version control software, you may want to clone the repo instead, which simplifies the process of updating your project later.
Satisfactory Mod Manager
offers a convenient developer mode that
automatically installs the correct version of SML and helps manage mod files for you.
To enable it, change your selected profile to
If you’re using Satisfactory Mod Manager,
you can skip the below steps and move on to the next page of the tutorial.
If you’re not using the mod manager, you’ll need to follow the manual install directions to get the relevant files set up.
Alternatively, once your modding environment is set up, you can use Alpakit to automatically build and install SML.
Now that all the dependencies are installed, you can move onto setting up the project.
