The 'WebVR' button in the module exports your image as a standalone HTML file. This file can be viewed locally in your webbrowser, or it can be hosted online.
It renders your image as an immersive VR experience, with a large screen wrapping around the viewer. The VR experience can be viewed in most popular headsets, including HTC Vive, Oculus, Windows Mixed Reality, GearVR, Google Day Dream and even sub-$5 Google Cardboard devices.
To view an experience, put it in an accessible location (locally or online) and launch it from a WebVR/XR capable browser.
Please note that landscape images tend to be more immersive.
