Publishing Your Mod

When your mod works the way you want, you can publish it to the Steam Workshop so other players can subscribe to it. Modmixer handles the upload for you.

Before you publish

A Workshop listing needs a few things beyond the mod itself:

  • A name and a short description
  • A preview image, the thumbnail players see in the Workshop

If any of these are missing, Modmixer asks for them before it uploads. You can ask it to write the description or generate a preview image if you don't have one ready.

Publishing your mod

With your mod open, go to the Publish tab, scroll to the Steam Workshop section, and click Publish To Workshop.

The process takes a few seconds, and then a link will appear for your published mod. Congratulations, your mod is live!

At this point you should go to the Workshop page and edit the description and images to show off your mod.

Updating a published mod

After your first upload, Modmixer remembers the Workshop item. When you make changes and publish again, it updates the existing listing instead of creating a new one. Subscribers get the update automatically.

The Steam Workshop description won't be updated when you push an update. This is on purpose so we don't accidentally overwrite a description you've carefully written on Steam.

AdvancedBe careful updating a mod that people already play with. Changes that rename or remove defs can break existing save files. If an update is risky, say so in the change notes so players know to start a fresh save. Ask Modmixer if you're unsure whether a change is save-safe.
