Hi beloved community, We're proud to announce that we've got a full support of the Windows Mixed Reality headsets AND Spatial Controllers in v3.1 :  We even have very cool animation of the controllers to enhance immersion. We're also working on simplifying a lot the creation of WebVR experiences in Babylon.js via the VRHelper. Stay tuned.
