Steam Workshop is a feature of Steam that simplifies mods discovery and installation for players.
Installing a mod
- Find a mod on the Stellaris Steam Workshop
- Click "Subscribe"
- In the Stellaris launcher, click the "Mods" tab and check the box.
Uploading a mod
Mod upload is managed from the game launcher:
- (Optional) Define an image banner and tags in .mod file.
- Launch the game launcher and go to the "Mods" tab
- Click on the "Mod tools" button and select "Upload mod" within the window that opens
- In the menu, select the mod you wish to upload and click on "Upload"
- After upload is finished, mod page will open inside the Steam client. Copy the URL (ex: steamcommunity.com/sharedfiles/filedetails/?id=123456) and open in your favorite browser, as it's easier than using the Steam client integrated browser.
- Add a description, screenshots or videos, and edit change notes.
- Once everything looks fine, make the mod public!
Mod file before upload (MyMod.mod):
Mod file when downloaded from Workshop (mymod.mod):
MyMod.zip will contain a generated descriptor.mod which is identical to mymod.mod.
In order to update a mod, hit the "Fetch Info" button before uploading the mod.
- Manage button is always greyed out: activate Steam Cloud Synch' for Stellaris (Steam -> Settings/(Preferences on mac) -> Cloud -> Enable cloud sync), it is required to upload mods.
The workshop has a few limitations, making it currently unsuitable for large mods:
- Modular mods that allow selecting modules at installation steps cannot be managed
- Maximum file size prevents large mods from using the Workshop.
Mods installed via the Steam Workshop will auto-update, so be careful about non-backward compatible changes as previous saves may become unplayable.
