The early access version of the next-generation engine is planned for release at the end of 2027, with a full launch 12 to 18 months later. UE6 represents a major departure from UE5 by integrating Unreal Editor for Fortnite (UEFN) into the core engine. The gameplay programming model will shift from C++ to Epic's original language Verse, which is already used in UEFN and is designed for building large-scale live service worlds with thousands of contributors. The visual scripting system Blueprints will be deprecated once the new framework matures, though conversion tools will be provided. Epic also committed to making UE6 an open specification platform, publishing systems as open specs with Verse APIs. Alongside the UE6 news, Epic released Unreal Engine 5.8, adding a Lumen Lite mode that enables global illumination at 60fps on Nintendo Switch 2, as well as Mesh Terrain for complex terrain shapes. UE 5.8 is described as the last major update before full-scale UE6 work.","whyItMatters":"The shift to Verse and the deprecation of Blueprints signal a fundamental rethinking of how games are built in Unreal, moving from a visual-scripting-friendly tool to a language-first engine optimized for persistent online worlds.","webCardHtml":"\u003cp\u003eEpic Games detailed the UE6 vision at Unreal Fest Chicago 2026 on June 17. The engine integrates UE5 with Unreal Editor for Fortnite (UEFN), which is currently a separate environment customized for \u003cem\u003eFortnite\u003c/em\u003e. Epic said UE5 and UEFN each have distinct strengths, and merging them is the core of UE6.\u003c/p\u003e\n\n\u003cp\u003eVerse, Epic\u0026#39;s original programming language, is already used in UEFN. The company said developers with experience in Python or C# should find it easy to learn. Verse has unique features for scaling problems in modern game development, and the new gameplay framework \u0026#34;Scene Graph\u0026#34; is built from scratch in Verse. Epic described Scene Graph as a foundation for sharing interoperable components across games.\u003c/p\u003e\n\n\u003cp\u003eEpic committed to making UE6 an \u0026#34;open specification\u0026#34; platform. Where existing standards like glTF and USD meet the engine\u0026#39;s needs, they will be adopted as primary formats. Where no standard exists, Epic will publish UE systems as open specifications with Verse APIs, asset conventions, and documentation that any engine or studio can implement. As a demonstration, \u003cem\u003eFortnite\u003c/em\u003e cosmetics will become \u0026#34;smart assets\u0026#34; that function across games, letting developers enable players to use purchased cosmetics in their own titles or create cosmetics for \u003cem\u003eFortnite\u003c/em\u003e.\u003c/p\u003e\n\n\u003cp\u003eAI tools Claude and Codex will play a more central role in UE6. Developers can combine and customize models for tasks like object placement and testing. A new plugin lets AI directly reference a project\u0026#39;s internal structure rather than requiring manual copy-paste of code. For video production, AI can take 3D scene data and camera positions as input to generate stylish videos while preserving composition. That tool is scheduled for early 2027.\u003c/p\u003e\n\n\u003cp\u003eUE 5.8, released alongside the UE6 roadmap, adds a Lumen Lite mode that runs twice as fast as Lumen High Quality while maintaining its quality. It enables global illumination at 60fps on Nintendo Switch 2 and is also supported on PC. The update also includes Mesh Terrain for creating complex shapes like caves and tunnels, and shader optimization that reduced the number of shaders in \u003cem\u003eFortnite\u003c/em\u003e by 68%. Epic said UE 5.8 is the last major update before full-scale UE6 work begins, though bug fixes will continue.\u003c/p\u003e","blueskyPost":"Epic says UE6 will deprecate Blueprints once the new Verse-based framework is mature, with conversion tools provided.
