Unreal Engine 4.22 Preview 1 now available
Preview 1 includes support for real-time ray tracing, Editor Utility Widgets, Movable Spotlight support on mobile, virtual production updates, Oculus Quest support, and Blueprint indexing optimizations.
A full list of the upcoming changes to this build are available on the Unreal Engine forums. We invite you to provide feedback on Preview 1, and all subsequent releases. Please keep in mind that Preview releases are intended only to provide a sample of what is going to be released in the update and are not production-ready.
To get started with Unreal Engine 4.22 Preview 1, head to the Unreal Engine section on the launcher, select Library at the top, then click the plus icon next to Engine Versions and choose 4.22 Preview 1.
We recommend waiting for the full release of 4.22 before updating your projects to the new engine version. For now, please use copies of your projects to test new features.
