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 + 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.
