Slate performance can be a huge concern for UI-heavy projects, and it’s often difficult to tell where exactly to make optimizations. Slate Global Invalidation provides a healthy performance boost in many cases, but how can you be sure it’s working properly? And what do you do when it fails? Watch this session recorded at Unreal Fest Chicago 2026 for a deep dive into UI performance, from the history of Slate itself to a thorough analysis of the Slate Tick using Unreal Insights. We break down the different parts of the Slate Tick, explore the various reasons your widgets may invalidate, and equip you with the knowledge you need to make smart decisions about where to focus your optimization efforts.

How do you move one of the most iconic 25‑year‑old game franchises from its proprietary tech stack onto a modern engine without breaking its soul? In this session recorded at Unreal Fest Chicago 2026, Halo Studios takes you behind the scenes of Halo’s multi‑year transition to Unreal Engine 5—a journey filled with breakthroughs, pitfalls, paradigm shifts, and a whole lot of learning. The team explores how this shift reshaped every discipline across the studio, from production rhythms to engineering mindsets to art workflows. You’ll hear how they re‑thought development methodology, rebuilt pipelines, retrained teams, and re‑examined assumptions that had been embedded in the franchise for decades. Along the way, they share the good, the bad, and the genuinely exciting moments when new tech unlocked ideas that were never possible before. Whether you’re leading a franchise reboot, modernizing a legacy codebase, or just curious, this talk offers practical lessons, surprising discoveries, and a candid look at what it really takes to reinvent a AAA pipeline while building ‘Halo’ for the future.

Players expect their games to follow them from the devices they have today, from Windows 11 PCs and handhelds to the future of the Xbox console. The Microsoft GDK plugins for Unreal Engine, publicly available in UE 5.8, give you a single path to build on Win64 to ship your games on all of these devices. In this session recorded at Unreal Fest Chicago 2026, Microsoft and Epic share the Xbox and Epic Games implementation plan, demonstrate plugin features, and examine how Epic Games itself leveraged these plugins to build and launch Fortnite on Xbox on PC.

In-island transactions add a new revenue stream on top of engagement payouts—and pricing your offers well is a design practice, not a one-time decision. In this livestream, we walk through frameworks for setting prices and packaging items across your catalog: a three-tier price structure (entry, mid, and premium), different pricing logic for durables vs. consumables, and when bundling serves your players better than individual offers. A bundle creation example from this stream is available in the Verse Code Snippet Repository on the Epic Developer Community—explore, reuse, and build on it in your own UEFN projects. https://dev.epicgames.com/community/fortnite/snippets Learn more about pricing and packaging your in-island transactions: https://dev.epicgames.com/documentation/fortnite/pricing-and-packaging-your-in-island-transactions-in-fortnite Learn more about getting started with in-island transactions: https://dev.epicgames.com/documentation/fortnite/in-island-transactions-in-fortnite Learn more about UEFN: https://www.fortnite.com/developer #Fortnite #UEFN #FortniteCreative #UnrealEditorForFortnite #gamedevelopment
