Unreal Engine 5.9 Preview Is Out & It Was Built With AI

AI workflow enhancements, Web platform support, rendering and animation updates, and more. Although Unreal Engine 5.8 was originally supposed to be the last major release before Unreal Engine 6, the team had already been collecting rendering and animation improvements for a possible 5.9 release next year. But just a week ago, they changed plans and decided to put together an Unreal Engine 5.9 Preview in time for the 2026 Epic AI MegaJam, which runs from November 12 to 15. It's is a pretty significant release, especially when it comes to how Epic Games builds Unreal Engine.
