On March 14 (local time), US Meta officially announced official support for the game engine “Unreal Engine 5 (UE5)” developed by US Epic Games. Content for the VR headset “Meta Quest 2” will be officially available with UE5, which has dramatically improved rendering quality.
“Unreal Engine” is one of the most popular real-time 3D production platforms in the world, along with “Unity”, which dominates the metaverse world, and UE5 is the latest version. Meta had released a development branch for UE5 before this announcement, but recommended using “Unreal Engine 4.27” for active app development, citing functional integration issues.
With this official support, the plug-in name has been changed from “OculusVR” to “MetaXR”. The API supported by Meta will be “OpenXR”. However, “Nanite”, which is the core of UE5 (a technology that automatically reduces the polygons of distant objects to reduce weight), does not work, and the original “Meta Quest” does not support UE5.
Meta continues to advise against upgrading Unreal Engine versions if you have projects in progress.
In addition, regarding the support for the current “Unreal Engine 4 (UE4)), it is clear that the patch “Unreal Engine 4 Integration” v55 scheduled for release in June will be the last to be reduced.
After v55, we will not provide new features or regular bug fixes for UE4, but we will continue to support important bug fixes until the end of 2023. Even after the end of support, the GitHub repository can be referenced, and there will be no restrictions on posting and distributing apps using UE4 to the “Meta Quest Store” or “App Lab”.
