Step 1
Basic Information
For this process to work, you need to be connected to the Steam Workshop.
Then fill in the:
Mod’s name
Version
Add a description
Thumbnail image
All of these fields are required.
Once you’re ready to move on to the next step, press Next.
Step 2
Time to cook
Once you start the cooking process, it will analyze the depot and files we used +
Once the progress bar is full, you can then move on the installing the mod (see next step below).
You can also find your mod files in your project’s folder without installing them.
The publish process will create two folders: cooked and packed. The first one is read-only and used for debugging. The second one is where your mod files can be found. These are the files which will need to be moved in the Witcher 3 game folder to start working.
3. Install the mod
To install the mod you have to first wait until the Publish process described above is completed.
Now, in the same window, expand the Debug Settings and select the Install box.
Now press the Publish Selected button.
This action will create a mods folder in The Witcher 3 game directory (IF you specified the correct \game folder during setup) and move the mod files from the packed folder there.
Your mod is now ready to be activated in The Witcher 3.
4. Start game with mod support
To see your mod in the game, you need to start it by opening a different executable file then usually.
Go to the game folder and find the game > bin > x64 folder.
Open Witcher3Release_Fullscreen_cooked.bat.
You should see this screen which opens the regular Witcher3.exe file, but with additional conditions (usebundles, noassert, splitcook).
Wait for the game to start.
In the main menu you will see an additional button (in the current production phase it’s: #DBG QUEST MENU).
When you press it, you should be able to select your mod.
Or more precisely, a Game Definition file (.redgame) which will launch your mod.
That’s it. You can test it out in the game!
Table of contents:
begin packaging them.
This means:
optimising the mod files
creating the mod bundles (like .zip files)
creating various caches (also .zip files but for textures, collision etc)
creating some metadata
This files will be saved in your mod directory in the \packed folder.
The full process can take up to a couple of minutes - it depends on the complexity of the mod.
Once the process is complete, press Next.
Step 3
Save and publish
The last step!
Choose a language and the visibility level for your mod (should it be public or not).
There are three things you can do here:
Export zip package - create a .zip file with your mod. Useful for uploading to NexusMods.
Install project - install your mod to your The Witcher 3 game.
Publish to Steam Workshop - if you feel like it, share your mod with others on Steam Workshop.
