New bPackageForOpenXRImmersive setting prepares Android XR builds without Quest-specific extras. Understand portability, profiles and tests at runtime.
Direct answer
Unreal Engine 5.8 adds experimental support for Steam Frame in collaboration with Valve and introduces the bPackageForOpenXRImmersive option, enabled by default in the VR Template. The configuration prepares Android OpenXR builds without the Meta Quest-specific additions and comes with Linux arm64 loader and device profiles. As support is experimental, compatibility, input, rendering and distribution need to be checked on the chosen hardware and runtime.
OpenXR separates application and vendor
The common API reduces proprietary code, but extensions, input profiles, and composition capabilities still vary by runtime.
Package flag defines build intent
Use bPackageForOpenXRImmersive for the generic Android OpenXR path and keep the Meta setting only when specific additions are needed.
Profile helps, but does not approve
Device profile defines defaults; temperature, resolution, memory, controls and comfort all need measurement on the actual device.
Experimental requires fallback and isolation
Don't base a critical delivery on unstabilized behavior without feature flags, version matrix and fallback plan.
Nexus Reading
Structure the project with a layer of capabilities: detect runtime, enumerate extensions, map semantic input and test the same case on more than one OpenXR target.
FAQ
Is Steam Frame support stable yet?
No. Epic classifies it as experimental in the Unreal Engine 5.8 notes.
What does bPackageForOpenXRImmersive do?
Prepares the Android package for an OpenXR immersive target, without the specific add-ons included in the Meta Quest path.
Does OpenXR guarantee the same behavior on any headset?
No. It standardizes interfaces, but capacity, extensions, performance and quality remain runtime and device dependent.
