Fortnite UEFN source assets on Fab are editable systems you can license and add directly to an Unreal Editor for Fortnite project. Epic opened the new source-asset category on October 15, covering systems such as AI and NPC behaviour, vehicles, weapons, UI and environments built with tools including Verse and Scene Graph.
These are editable project assets. Once licensed, the package sits in your Fab library and can be added to UEFN, where you can inspect and change the actual system instead of only referencing a finished file.
How to add Fortnite UEFN source assets on Fab

To add Fortnite UEFN source assets on Fab, find the asset on Fab’s website or browse the Fab window from inside UEFN. Open its listing, review the licensing information and restrictions, select the licence you need and complete checkout.
The asset is then added to your Fab library. Open the UEFN project where you want it, bring the source asset into the project and start working with the imported content. Paid and free listings use the same basic library workflow.
What is a UEFN source asset?
A source asset is a complete editable system or content package rather than a file you can only point to. Epic’s first examples include its free Verse UI Kit, a Scene Graph Pathfinder system and production-ready environment packs.
With Fortnite UEFN source assets on Fab, you can open the Verse or Scene Graph setup and change it for your island. That also makes these assets useful for learning how a working system has been assembled, not just dropping somebody else’s finished work into a map.
UEFN source assets available now

How licensing works
Each listing has its own licensing details and restrictions, so check those before checkout. Once licensed, Fortnite UEFN source assets on Fab remain in your Fab library, giving you a stable route back to the package instead of treating it like a one-off download.
Some Fortnite UEFN source assets on Fab are free, including Epic’s Verse UI Kit, while third-party creators can sell their systems. Before adding any Fortnite UEFN source assets on Fab to a project, check the licence attached to that specific listing.
Can you edit the Verse and Scene Graph content?
Yes. Epic’s source-asset announcement specifically highlights systems built with Verse and Scene Graph because the editable implementation is part of what you receive. Pathfinder, for example, uses Scene Graph entities and a single Verse component that can be configured for different targets and arrow styles.
A source asset can be a starting point rather than the final result. You can inspect the system, change its behaviour and keep only the parts that suit the experience you are building.
Can you sell your own UEFN source assets?
Yes. Creators can publish source assets through Fab if they made the work or hold the rights required to sell it. Epic says publishers earn 88% revenue share on source-asset sales.
Existing Fab publishers can create a listing through the Publishing Portal. New sellers need to become a Fab publisher first, then follow the UEFN source-asset publishing and technical requirements before the listing can go live.
What should you check before licensing an asset?
Read the description, licence and restrictions first, then match the asset to the job you actually need done. A polished environment pack will not solve a UI problem, and Pathfinder serves a very different purpose from Epic’s Verse UI Kit.
Epic says every listing is reviewed for UEFN technical standards before it is published. Customer reviews then give you a second signal once more creators have actually used the package in live projects.
