Satisfactory Modding Documentation
Welcome to the Satisfactory Modding Documentation site!
Here you can find lots of information regarding modding Satisfactory, the factory-building sim by Coffee Stain Studios. Modding for Satisfactory is more established than you might think given how long the game has been out. There are already numerous mods released, and there are multiple methods by which you can develop new mods yourself.
In this doc we will mainly focus on the general community, ficsit.app and SML.
If you want to take part in this great community, we recommend you to join our Discord Server or the Ficsit.app Forums.
Satisfactory Mod Repository (aka. SMR aka. ficsit.app aka. FICSIT Augmentation Database)
The Satisfactory Mod Repository (SMR) is the most extensive collection of mods made for Satisfactory. It’s easy to upload a mod of your own or write a guide for other users. Uploaded content gets tested for malware and other potential issues. Visit ficsit.app to learn more.
Satisfactory Mod Loader (aka. SML)
Satisfactory Mod Loader (SML) allows Satisfactory to load additional content and is essential in making most mods work. SML provides two key features.
Loading and initializing mods directly from "pak" files
Loading and initializing native mods written in C++
If you’re looking to write your own mods, we suggest you start with
making pak mods. Learn more in our
If you just want to install mods, this section of the guide is for you. First of all, you need to pick a mod that you want to install. Take a look on the SMR. Please note that there are multiple pages of mods you can navigate through with the arrows at the bottom right. You should always read the mod description because some mods have different installation instructions that need to be followed (such as KronosMod). If instructions aren’t followed, the mod won’t work. Most likely the mod you choose will require you to install SML; The purpose of this guide is to help you achieve that goal.
Visit ficsit.app and open up the menu through
the menu button in the upper left hand corner. Select the
SML Releases tab and click on the
View button on the Latest
Release box (top left). You should now get redirected to the SML GitHub
page. Click on the
xinput1_3.dll download link under Assets and
save it to your downloads folder. Follow the instructions there to
install, or follow the instructions below.
Now open up your Satisfactory installation folder. Most of the times its
in your program folder under

Win64. Now just copy the
xinput1_3.dll into that folder.
Congratulations! The first step is done, installing SML. Now, start up
Satisfactory and verify that a
mods folder gets created in your
Installing Your Mod of Choice
Ok, back to the mod
itself. On ficsit.app you just go to your desired mod’s page, click on
versions in the upper right left corner and then click
on your desired version. Usually this will be the top version on the
Always check to make sure that the SML Version column for the version you choose matches the version of SML you have installed. You can attempt to install the mod with mismatched versions, but most of the time, it won’t work.
Save the zip file to your downloads folder and then open it with a proper zip archive explorer like 7zip. It contains multiple files, which include some but not necessarily all of the following:
Used by SMR to identify the mod. You don’t need to do anything with this file.
- .pak files
These files contain some mod logic, models, textures and so on. To install them you need to copy them again into the Satisfactory installation folder, but this time under
.pakfile should have a
.sigfile with a matching name. If there is no corresponding
.sig-file for each of the
.pakfiles in the archive, you’ll need to copy the
.sigfile used by Satisfactory (it’s called
FactoryGame.sig) and rename it to match the
.pakfile you’re copying in. Repeat this step for each
.pakfile there is.
- .sig files
See above. Copy them to the same place as the
.pakfiles if you haven’t done so already.
- .dll files
These files contain mod logic but interact with the game differently from
.pakfiles and are installed differently. Copy these files into the
modsfolder. If you don’t have this folder, you forgot to run Satisfactory after installing SML.
Installing Mod Dependencies
Some mods, such as the Farming Mod, will require you to install other mods in order for them to work. Read the mod description on the SMR page to find out if the mod you’re installing requires any other mods! People will be very frustrated if you ask them for help and you haven’t followed this simple step.
If you see this message, you forgot to install the Satisfactory Item Dictionary mod, a common dependency. Go find it on SMR and install it!
