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.

Updating Existing Content

Modders wanting to update their content that they already have uploaded to the Workshop can do so. This will allow players of their content to automatically be updated to the latest version without having to do anything on their own.

To do so, modders need to select the

Update Steam Workshop Upload

option from the tools list. After doing so they will be presented with a list of content they have uploaded previously.

After selecting the content they would like to update, they will be presented with the Upload box already filled out with the previous settings and files used to upload that content. They can make the needed changes (if any) and proceed to upload.

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)
All content be uploaded from their proper location (Maps, Texture, System, Static Mesh folders) within the file directory as it will help with the update process

On Steam

After a successful upload of content to Steam, modders have the ability to view their content in the workshop and change some settings related to it.
