Metrotopia Inc, is a US-based startup founded by Zaha Hadid Architects (London) and ArchAgenda (Chicago) after multiple years collaborating in the metaverse space. Built on Unreal Engine 5 and accessible online via Pixel Streaming, Metrotopia is a virtual world offering a high-fidelity digital environment that enables new forms of architectural, cultural, and interdisciplinary exchange. Designed as a global platform for the wider design ecosystem, it brings together architecture, industrial design, fashion, mobility, and speculative practices. The virtual environment showcases over 100 high-resolution projects by leading international architectural studios and designers, including Zaha Hadid Architects, Coop Himmelb(l)au, UNStudio, Sou Fujimoto, ArchiUnion, OMA, LAVA, as well as industrial designer Ross Lovegrove, fashion designer Yimeng Yu, and contributors working across conceptual and emerging design fields. This session recorded at Unreal Fest Chicago 2026 explores how Unreal Engine can be used within the AECO industry, industrial design, fashion, automotive design, and the wider design ecosystem to showcase detailed high-resolution assets in an immersive fashion within one virtual environment thanks to features such as Nanite, Lumen and World Partition. The presentation shows the process of importing complex architectural models and high resolution assets and incorporating them into one large shared multiplayer environment.

Shop UI shapes how players engage with in-island transactions. In this livestream, Derek Diaz, UI/UX Director at Epic Games, walks through menu patterns for different kinds of shops—from complex, category-heavy inventories to simpler, more focused layouts—and look at how to handle what players see after they complete a purchase Every UI example from the stream will be published to the Snippets Repository on the Epic Developer Community, so you can explore, reuse, and build on them.

Sick of zombie bugs that keep coming back in your most important systems? Do you want to get the most out of your limited QA hours? Join us as Andrew Fray explores the test automation tooling in Unreal 5 and learn how good automation can let you focus on gameplay instead of bugs.

What if relevant, targeted, high-quality synthetic data was just a prompt away? Simulation is an indispensable tool for building physical AI systems, enabling faster training, safe testing, and systematic discovery of edge cases. However, simulation workflows often require proficiency with 3D tools and are constrained by slow, cumbersome customization. Generative world models, by contrast, are intuitive and highly flexible—but they lack the physical grounding, reproducibility, and controllability required for meaningful training and validation. In this talk recorded at Unreal Fest Chicago 2026, Duality AI introduces Unreal Engine–based vibe simulation: a new approach that reconciles the intuitiveness and flexibility of generative world models with the accuracy, determinism, and physical grounding of simulation. Vibe simulations enable users to modify scenarios using natural language prompts and an intuitive agentic interface, while retaining the precise control required for AI introspection, validation, and repeatability within digital twin environments. Watch Duality AI CEO Apurva Shah cover both implementation details and live real-world demo examples. The talk explores how vibe simulation transforms static simulations into critical decision-making and data tools accessible to all users across an organization.

The quest for enhanced realism and deeper player immersion is constantly constrained by performance. Fast and accurate simulation is a cornerstone of next-generation games, and for several years, we’ve been pushing the limits of the Unreal Engine physics engine, Chaos. Watch this session recorded at Unreal Fest Chicago 2026 to uncover a long-term optimization journey that has delivered up to 40% performance gains in targeted scenarios—without sacrificing stability, backward compatibility, or memory footprint. This has not been the result of a single fix or isolated optimization, but of a sustained, methodical effort driven by deep profiling, scalable algorithm design, aggressive use of multithreading, and meticulous low-level code optimization. In this presentation, Epic Games Physics Programmer Vincent Robert does a deep dive into the key algorithms, architectural trade-offs, and lessons he learned from optimizing Chaos, as he sought to enable complex simulation workloads to better exploit modern hardware even when faced with traditional sequential constraints. While the context is physics simulation, the core theme is performance optimization. You’ll come away with practical, reusable techniques and mental models that can be applied across a wide range of systems to unlock additional performance.

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.
