i heard that openxr isnt needed for vr if you have metaxr installed and that metaxr can not like openxr… soooo… i uninstalled openxr now i can’t play preview in vr button. it is grayed out.
As far I understand MetaXR is an extension of OpenXR. In the past it was not possible to run VR preview mode when both plugins were enabled, but that has been solved with UE5.4.
You should have enable both, MetaXR and OpenXR plugin. While OpenXR offers basic functionalities, MetaXR provides special features for the Quest HMDs, like for the controllers, hand tracking, etc.
Also the MetaXR plugin provides an easy project configuration to make performance optimizations and to configure your build settings for Quest devices. And it has a kind of a simulator, that allow to test your game or VR project without need of a headset.
