Epic、「UE5」と「UEFN」は「Unreal Engine 6」に統合されると発表

Epic says it has started the road to Unreal Engine 6, describing a future where Unreal Engine and UEFN come together into a single, unified engine. In its new roadmap post, the company says it is building toward portability, open specifications, and shared systems across games and engines. The road to UE6

The post says Epic is targeting Unreal Engine 6 Early Access at the end of 2027, followed by a full release 12 to 18 months later. Epic also says the new UE6 development stream is now publicly visible on GitHub. The road to UE6

What Epic says will carry over

• UE6 is intended to preserve a manageable path from UE5 projects.
• Epic says Fortnite development will be attached to the UE6 stream.
• The company says it wants portable content and code across ecosystems.

A key part of the plan is portability: Epic says Fortnite cosmetics will be its first proof point, with the option to use entitled Fortnite Outfits in other games and tools to build outfits that work inside Fortnite. That suggests a broader cross-game economy is a central goal of the UE6 architecture. The road to UE6

For UEFN creators, the practical takeaway is that Epic is not treating Fortnite tooling as a side branch. Instead, it is presenting UEFN as part of the live testbed that will shape the next engine generation. The road to UE6
