Wreckfest's Steam Workshop support did not ship at launch. It arrived through two dated updates in 2016, and the modding format Bugbear Entertainment set up then is still the one custom tracks use today. This guide covers when it shipped, what a track mod is actually made of, and how to find and install one now.
When Modding Support Arrived
April 20, 2016: Modding Support
Bugbear shipped a "Modding Support" update that laid the groundwork for player-made content in Wreckfest. This update predates Workshop integration itself, it opened the door for the track-modding update that followed a month later.
May 20, 2016: Steam Workshop & Track Modding
A month later, Steam Workshop support and track modding shipped together. The same update also improved the Mixed 1, Sandpit 2, and Mixed 2 tracks. This is the update that made custom tracks distributable through Steam Workshop rather than manual file sharing.
Both updates are documented in the dev-blog record on this archive's 2016 timeline section, alongside the rest of Wreckfest's development history.
What a Track Mod Is Actually Made Of
Custom track data in Wreckfest lives inside a mod's data/track
folder. That is the location the game reads when a track mod is loaded, whether it came
from Steam Workshop or was placed there manually. Bugbear shipped this system with an
example to learn from rather than leaving modders to reverse-engineer it: an example
track under mods/example/track, and a
reference document, tools/track_modding.doc,
bundled with the May 2016 update.
For anyone building a track mod rather than just playing one, that bundled example is the practical starting point: open it, see how the folder is laid out, then work from the included documentation rather than guessing at the format from scratch.
Finding and Installing Workshop Mods Today
Steam Workshop is Valve's standard distribution layer for Steam games, and Wreckfest uses it the way most Workshop-supported titles do: mods are browsed and subscribed to through the game's Workshop page on Steam, and a subscribed mod is downloaded and made available to the game automatically, without manually copying files into the install folder.
Exactly how subscribed content is presented inside the game (menus, load order, and so
on) is worth confirming directly in the current build rather than from any outside guide,
since in-game interfaces get refined across updates in ways a static page cannot track in
real time. The underlying mechanism, Workshop subscription plus the
data/track folder structure set up in
2016, is the part that has stayed consistent.
Building a Track Mod From the Bundled Example
Anyone starting a track mod from nothing has an easier path than reverse-engineering the
format: Bugbear's May 2016 update shipped with a working example specifically so modders
would have something concrete to open and study, rather than a blank format spec. Reading
through mods/example/track alongside
tools/track_modding.doc before writing
anything new is the fastest way to see how the pieces fit together, since it shows a
complete, functioning track rather than an abstract description of one.
The same update that added the example also reworked the Mixed 1, Sandpit 2, and Mixed 2 tracks, which is worth knowing if an older guide or forum post references those tracks by a previous layout, they may not match what ships today.

When did Wreckfest add Steam Workshop support?
Steam Workshop support and track modding shipped on May 20, 2016, following a broader "Modding Support" update released a month earlier on April 20, 2016.
Where does custom track data live in a Wreckfest mod?
Inside a mod's data/track folder. Bugbear bundled an example track and
a reference document with the May 2016 update specifically so modders could learn
the format from a working sample rather than guesswork.
