Large worlds in UE5: A whole new (open) world

Arran Langmead |
September 28, 2021
Open world is a major part of development in the games industry—everything from Assassin’s Creed to Zelda features vast sprawling worlds for players to explore. But despite its popularity, open world creation has continued to be a difficult task for many developers. That’s all changed with the release of Unreal Engine 5. Now, creating these open worlds has never been easier.

In this talk, Arran Langmead, Technical Artist and Evangelist for Epic Games will give you a complete overview of the new open world features in UE5 and how to set them up, including World Partition, One File Per Actor, Minimaps, HLODS, Data Layers, and Level Instances.
