Killing Floor Steam Workshop

Modding

Long before the Steam Workshop, Tripwire (which grew from modding roots) has been very supportive of the modding communities that have grown up around their games. From maps, to mutators (which covered new weapons, gameplay changes and more), to Total Conversions that completely changed the game. None of that has changed, and Tripwire continues to support those communities as much as possible. To that end, Tripwire has decided to implement Steam Workshop, a better method for modders and those who would use them to upload, find, and use content!

Getting Started With Workshop

As of September 2012, Killing Floor has supported Steam Workshop. Workshop allows modders to easily upload their content for a game and make it available for all the people that own it. For end users (not mod makers), it offers a one click solution to find mods that they like for a game they own, and always have it be up to date and ready to play on any machine they may play the game on.

The only thing modders and players need to access and use Killing Floor and the Workshop is to have Steam, and own Killing Floor. The Workshop and the SDK are free to all owners of the game.

Players looking for instructions on how to subscribe, download and use workshop content should skip to player section of this article.

Modders

In The Editor

This section will cover the new additions to the editor that allow modders to upload their content to the Workshop. This section will not cover how to use the Killing Floor Editor. Players can find more in depth tutorials and pages on that here.

Modders opening up the Killing Floor editor will now find new entries under the tools list.

The new entries are:

Update Steam Workshop Upload

Upload File(s) to Steam Workshop

Uploading New Files

The first thing modders will want to do, is to upload their maps and mutators to the workshop for the first time. To do this they need to select

Upload File(s) to Steam Workshop

When they have done so they will be presented with the following 'Upload Box'

Uploading

Once the player is familiar with the Upload Box, they need to fill it out and select the file(s) for upload. This includes the maps, textures, static meshes, and .u files associated with their content.

An example of a filled out and ready to upload map can be found in the image below for KF-MountainPassNight

After filling out the Upload Box and hitting the upload button, the player will be informed that the content is uploading in the example below:

The upload will either end in success, and the modder will receive the message:

Upload Successful

or in an error in which case the modder will see:

The Upload Has Failed

In which case the modder will need to debug why, and try again.

Known Errors to Avoid

All content uploaded to the Workshop must follow the following rules:

All content uploaded (including the preview image for the content) must be contained within the Killing Floor file directory. 
Content uploaded can only be the following file types: Maps (.rom), Texture, Static Mesh, and Script (.u)
