maybe more related Link ??

is this can maybe related ? can you confirm we can map vr with nwjs APP ? If yes , can we add this as feature requests ? https://github.com/nwjs/nw.js/issues/4259 Or any help to fix this issue ? thank you so much and keep good job.

It should be supported as long as it works with Chromium. I'll need a device to reproduce and fix this...

@rogerwang if you have window 10 developer , you no need headset to run mixed reality . Microsoft made a simulation feature, but i never test by myself. I have a colleague who uses this to develop under unity. https://www.laptopmag.com/articles/experience-windows-mixed-reality-without-headset Maybe this can help you to test.

Also i also forgotten to mention, you can see in the video upper. It not work with nwjs, but if i pass by a web browser, it work fine. It why i think it can be related to nwjs.

webxr webvr only works on https secure maybe this could be the problem

[jonlepage]

Any way to make nwjs run in secure local space ? maybe a flag ? "chromium-args": "--force-secure-content", I search but cant find.
