To publish mod on the Workshop, following things are necessary:

  • Working mod (if it was published before, you have be owner of that mod)
  • Bohemia Account

If you already have Bohemia Account, then you can login to Bohemia backend by using Workbench > Login option. This option should open new pop up window where it is possible to type email & password associated with Bohemia Account. After that was typed in, you can click on Login button.

If you don't have account or you don't remember password to it, it is possible to click on Forgot Password? link, to initiate password recovery or use Create Account link, to create a new Bohemia Account.


Publishing a mod is the process of making the mod available on the Workshop. A bundled mod is required.

In order to do so, click on Workbench > Publish Project

This will open the following interface:

Publish project window
Workshop in-game interface

The following fields are offered:

Bundling Process

Bundling creates packed data, where any unneeded source files are removed, manifest.json - where backend related data is stored, copies pictures (preview image, screenshots, mission previews) and prepares zip file, with all previously generated data, which is ready to be uploaded to Workshop. The editable data set is called the source files. Once packaged, this is called packaged files or package – the data is compressed, indexed and encrypted.

  • Packaged files are meant for public distribution
  • Packaged files cannot be extracted back to source files – so be sure to keep them safe and with backups!
  • Source files are ignored:
    • .meta
    • .txa (text animation)
    • .txo (text model) see File Types and Extensions for full list
  • Deflate compression is applied to the resulting files
    • .anm, .data, .edds, .et, .nmn, .wav, and .xob are excluded from compression
  • Encryption

Depending on the size of the project, bundling process can take from few seconds to couple minutes.

Publishing Process

When everything needed is filled and bundle was prepared, click on Publish to publish the package to the workshop.


To update an already published mod, open the mod project again with the Workbench. Apply any changes needed (data, metadata), fill the new Change Notes field with the changes applied, and press Bundle to update the data.

Once bundling is completed, push Publish button to send your changes to the server.

Any change to description, visibility, pictures, etc has to be bundled first and then published as new version.

CLI Parameters

Mods can be bundled and packed using command line parameters documented at Startup Parameters - Workbench.
