Building for Rocket Racing meant one route only: Epic’s own UEFN pipeline, opened to creators on March 20, 2024 (UEFN v29.01) with the “Build Your Own Rocket Racing Islands with UEFN” release. A third party modding API never existed. Everything outside that pipeline (stat trackers, map code databases, speedrun timing files) is thin, and the only dedicated RR conversion/recovery tooling that exists was built by this archive’s maintainer and published under ShrezesUverse on GitHub (Section 7.2).
7.1 Official track building pipeline (UEFN)
The March 20, 2024 release shipped two starter templates, Competitive Race Track (up to 12 players, multi lap) and Speed Run Track (single lap time trial), plus a device suite (Epic announcement; template catalog). All RR devices remained labeled “Beta” in Epic’s documentation throughout the mode’s life.
- Rocket Racing Track device · the core spline based track editor. Color coded splines (green = primary, blue = secondary, white = cosmetic), five road shapes (Flat Road, Banked Road, Half Pipe, Tunnel, Pipe), a Track Style Editor, and a hard limit of one primary spline per island. By Epic/Psyonix; Beta labeled to the end.
- RR device suite · RR Checkpoint, RR Competitive Race Manager, RR Speed Run Manager, RR Player Start Position, RR Boost Pad, RR Elimination Volume, RR EMP Volume, and RR Active Track Volume. Island validation required checkpoints in order and branching paths converging to a single finish line. Dedicated docs cover the Speed Run Manager and Competitive Race Manager; the parent hub is Working with Rocket Racing Islands in UEFN, with a step by step build companion.
- Rocket Racing Vehicle Spawner · spawns RR cars with Drift/Fly/Turbo/Air Dodge abilities and syncs with the player’s Locker. Distinct from the older Octane Spawner, a Rocket League car device available in Fortnite Creative since v22.10 (October 2022), which predates and is separate from the RR vehicle system.
- GDC 2024 talk: “Building New Rocket Racing Experiences with UEFN” · Psyonix’s presentation of the creator workflow, hosted on the Epic Dev Community; the forums announcement thread and Epic’s official launch video accompanied the release. Editor plans had leaked prerelease (Insider Gaming, unverified).
Known defects. The most complete bug list is the March 29, 2024 Epic forums thread “All issues with Rocket Racing UEFN tools”: UEFN crashes when sculpting near spline nodes, music setting ignored, broken checkpoint respawns in private codes, no segmented track testing, editor vs live physics mismatch, and no ghost trail debug recording. Ticket FORT-743381 was closed by January 2025 without resolution. Later reports include a broken track spline, a 2025 regression where moving splines stopped affecting tracks, and a respawn on spline issue.
7.2 Conversion & recovery pipelines
The RR native tooling, built by this archive’s maintainer. For most of the mode’s life there was no track conversion or content recovery tooling at all; the gap was eventually filled by community dataminer shrezee (this archive’s maintainer), publishing on GitHub as ShrezesUverse:
- UEFN_RocketRacing_TrackConverter (Python + standalone .exe) · fixes deprecated RR tracks that no longer pass UEFN validation: “If Epic’s update broke your old tracks (they won’t validate), this little tool fixes them.” Clipboard workflow: copy the old track in UEFN, run the converter, paste the reformatted track back; segments and segment types are preserved, only the data format is updated (README advises testing on one track first). The only known dedicated Rocket Racing track converter.
- UEFN-Rocket-Racing-Asset-Pack (released July 1, 2026) · a full DelMar content uncooker: it converts Rocket Racing’s cooked runtime content back into editable, UEFN usable form and exposes the complete set in the content drawer, delivered as two
.uassetfiles (DelMar.uasset,UEFN_Expose_DelMarCoreContent.uasset): “Everything that exists in Rocket Racing is included, not a partial set.” Installed into the Fortnite directory, it makes the official RR content buildable in creators’ own islands: the practical community side recovery path for rebuilding official track content as standalone islands before the sunset. (Per the README: a handful of assets fail validation; not affiliated with Epic, takedown contact provided.)
Epic’s official migration path is separate: the April 2026 integration of car physics, hazards, and track tools into base UEFN, with convert to standalone island guidance (Section 6.11, Section 21.7).
A conflation to avoid: Rocket League maps are not Rocket Racing tracks. The neighboring Rocket League Map Making scene has its own UDK era tooling (RLMM tools page: Blender to UDK plugin, UDKObjectGenerator, UPK Browser, BakkesMod map loaders, none targeting UEFN or RR; RLMM GitHub org; RLMM Discord). No RL→RR converter ever existed; porting an RL workshop map meant manual mesh export (Blender/FBX) plus hand rebuilt splines, and that is a porting curiosity between two different games’ content, not part of the Rocket Racing preservation pipeline. (Generic mesh tools like the paid Racing Track Generator Blender add on likewise have no RR spline integration (unverified).)
7.3 Learning resources
- My First Rocket Racing Track · Cleverlike UEFN Creator School · free structured course on foundational RR track building, by Cleverlike Studios.
- YouTube tutorials: a long form beginner “Ultimate Guide”, full custom track walkthroughs (another), an easy beginner tutorial, launch week coverage, and a secondary track/shortcuts guide.
- Forum Q&A such as road material swapping and showcase threads like Dusty Desert served as informal documentation.
7.4 Map code discovery & databases
- fortnite.com/categories/rocketracing · Epic’s first party directory of creator RR track codes; usage guides existed at Gamerant.
- fortnite.gg Most Played Rocket Racing Maps · live CCU rankings of racing islands; in practice the main RR map database. Its island pages even indexed Epic’s internal ranked track sets with stats.
- Dropnite, FortniteCreativeHQ, FortniteMaps · generic map code databases listing RR islands among Creative codes.
- Fortnite Wiki · Tracks · community wiki database of all official RR tracks.
7.5 Stat & leaderboard trackers
- fortnite.gg Rocket Racing Leaderboard Tracker · dedicated third party RR ranked leaderboard/stat tracker at /racing-stats.
- Fortnite Tracker (TRN) · ranked RR leaderboards; users requested full RR profile stats on the feedback board, indicating coverage gaps that were never closed.
- Epic official ranked leaderboard · first party RR ranked standings. In game Speed Run time trial leaderboards launched with v28.30 (Feb 2024); after v31.40 (Oct 12, 2024) ended themed updates, Ranked resets and Speed Run leaderboard resets became the mode’s main cadence, with creators pointed to UEFN.
7.6 Speedrun timing tools
- speedrun.com/Rocket_Racing · main board. Its resources page holds the only timing tools that ever existed: four LiveSplit .lss split files (Novice, Advanced, Expert, All Tracks) authored by user Meta circa 2024. No autosplitter exists; timing is manual/in game, per the Manual Game Time guide.
- Rocket Racing Category Extensions · CE board including trackless runs; Community Tracks board · separate board for UEFN creator tracks, resources section empty. speedrun.com also ran an official SRC Series Expert Tracks cash challenge.
7.7 GitHub repos & misc utilities
- sanxfxteam/uefn-devices and mikeyaworski/UEFN-Verse-Devices · generic Verse device code examples/utilities adaptable to race island logic; nothing RR specific (unverified).
- Fab marketplace, “racing” tag · environment/prop assets usable in RR islands; no RR specific plugin category existed on Fab.
- Fortnite Developer Tools portal · Epic’s hub for UEFN/Creative tooling; Rocket Racing Discord · main community server including track creator channels.

7.9 Honest assessment & endgame
The RR tooling ecosystem was shallow by design: no modding API, no data API for stats beyond what trackers scraped, no export path, and no first party conversion story until the very end. Community energy went into tutorials and bug threads rather than tools, becuase there was little to hook into; the notable exceptions are the maintainer’s own ShrezesUverse converter and asset pack (Section 7.2), which arrived late and went essentially unnoticed on the open web. With the March 24, 2026 shutdown announcement (see also Epic’s shutdown FAQ), the dedicated track creator was discontinued (migration path: Section 7.2).
