Unreal Editor for Fortnite
Cary, North Carolina, USA
What it is
Unreal Editor for Fortnite (UEFN) is a free suite of Unreal Engine-powered tools for creating and editing props and devices. Creators can build terrain, add props and game mechanics, adjust lighting, and sculpt landscapes. Verse tools support device customization, custom devices, game rules, and NPC behavior. Live Edit lets creators work in UEFN and Fortnite Creative simultaneously and push changes to the Fortnite client. Unreal Revision Control provides project snapshots, history, conflict resolution, and auto checkout. UEFN integrates with Fab to browse and import third-party assets marked with a UEFN tag. The Creator Portal manages and publishes UEFN and Fortnite Creative projects, with team management, private playtests, analytics, and monetization tools. UEFN runs on Windows PCs and requires an Epic Games account, Epic Games Launcher, and Fortnite. Minimum listed requirements include Windows 10 64-bit version 1909 revision .1350 or higher, a quad-core 2.5 GHz CPU, 16 GB RAM, and a GTX 960, R9 280, or equivalent DX11 GPU. Epic warns that projects and some third-party assets can run code or access computer data.
