I just tested successfully this WebVR demo with Firefox and my HTC Vive Pro.
The inputs are not well mapped on my Index Controller but that’s not the point.
The problem is when I start a new project with the VR Starter kit using the same browser (Firefox).
When I hit play, it shows a message saying that “WebXR is not supported” (using Firefox)
I tried in Chrome (with officially support WebXR) but sadly, Chrome is not compatible with HTC Vive Pro (it did not detect my HMD when trying to enter in VR, it’s seem compatible with mobiles HMD only).
What are my solutions here? Trying to duplicate the WebVR demo without using the VR starting kit?
