Unreal Archive Overview

Updated: Apr 17, 2026

The topics in this section contain reference information for retired features. These features are no longer supported outside of existing legacy apps in the Meta Horizon Store. The content here is retained for reference purposes for those legacy apps built using Unreal Engine.

Archived content will not be updated. The topics in this section will be retained as long as legacy apps require them. If you’re using retired features, we recommend using supported alternatives.
