Unreal MCP is now available in Unreal Editor for Fortnite (UEFN). Join UEFN Evangelist Magnus Enebakk as he walks you through Model Context Protocol (MCP) in UEFN and shows how agentic coding tools like Claude Code or Cursor can work with you in the editor: writing and compiling Verse, placing and configuring devices, and running play sessions to test results.

When it comes to creating stylized games and animations in Unreal Engine, many teams rely on the manipulation of materials. But did you know you could combine the power of the engine with the simplicity of a 2D toolset like Odyssey to create stylized content? In this talk recorded at Unreal Fest Chicago 2026, Praxinos explores the different workflows the Odyssey 2D plugin makes possible. They cover various aspects of using Odyssey to mix 2D and 3D for beautiful stylized games and animations, including how to bring real paintings into Unreal Engine with the scan cleaner; how to paint on props and characters without third-party software; how to 2D animate in a 3D environment; and beyond.

In this session recorded at Unreal Fest Chicago 2026, Chris Zukowski of Zuko Media demonstrates an Audio-FX-Stack method of building and changing MetaSounds at runtime using the MetaSound Builder API, along with various methods to visualize them. This workflow uses the live update option for the API, which comes with a few gotchas. These techniques are showcased in ‘Mix Universe’—Zukowski’s musical sandbox game where you play as a Mixonaut adding beautiful vibes to the universe—to build and play hundreds of sounds at runtime, using Niagara to make them look cool. It is useful to have prior C++ experience to understand the more technical aspects of the talk, but anyone interested in Unreal Engine’s innovative audio technology will find the recording useful, too.
