Open Darktide-Mod-Loader-xx-x-x-x.zip and extract all the files into your game folder. e.g. Steam\steamapps\common\Warhammer 40,000 DARKTIDE
Go into your game folder and run the file toggle_darktide_mods.bat, which will patch the game to load mods
There is no confirmation, other than a command prompt window that quickly opens and closes
If it fails and you have already made sure that it's installed in the correct location, the alternative patcher can be used by going to the tools folder then running the dtkit-patch.exe executable file
Open PreviewCosmetics-xx-x-x-x.zip and move the PreviewCosmetics folder into the same mods folder as you put dmf
Make sure that the folder structure looks like the image below, with no subfolders between the scripts folder and the <Mod Name>.mod file (where <Mod Name> is the folder name, see the blue boxes in the mentioned image)
Though this image uses the Scoreboard mod as a reference, the structure is the same as in the PreviewCosmetics mod, as well as the vast majority of mods
Your operating system may misidentify the <Mod Name>.mod file as a Movie Clip even though it's a text file. It doesn't matter what your OS thinks it is, as long as the .mod extension is present. If it's not, ensure that you have enabled viewing file extensions in your file explorer.
In order for the mod to load, you must type the folder name (in this case PreviewCosmetics) into the mod_load_order.txt file located inside the mods folder
Remember to save the file
Before you panic, check out the GIF below. Fortunately, it's not that difficult.
So every time you download a mod, drop it into the mods folder, and then type the folder name, exactly as it is, into the mod_load_order.txt file.
Here's another GIF, with a few other mods:
Done! Check the new "Mod Options" inside Darktide, in the [ESC] menu.
Additional notes
If the steps above fail, check that your anti-virus does not have the files quarantined or blocked
Notes for Microsoft Store or Xbox Game Pass players
The game files may be found in a folder similar to one of the following:
Linux users can follow the guide as is, except for step 3. Here are the alternative methods:
Using manshanko's precompiled Linux binary. Run this binary by executing ./tools/dtkit-patch --patch bundle in the terminal, while the Darktide game folder is the current working directory.
Running the Windows dtkit-patch.exe through compatibility tools, such as Proton. One way of doing this is through Steam. Add it to your library as a non-Steam game, then write --toggle ../bundle in the launch options, then launch it from your Steam library.
