It still has a error with the alpha.62, I packed the code and the error image to the zip file.

when I change to alpha.50 (use the following code), it works fine:

<!-- <script src="./scripts/babylon.js"></script>
    <script src="./scripts/babylonjs.loaders.min.js"></script> -->
    <script src="https://cdn.jsdelivr.net/npm/babylonjs@5.0.0-alpha.50/babylon.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/babylonjs-loaders@5.0.0-alpha.50/babylonjs.loaders.min.js"></script>

I believe the change is not yet in the preview release, as we have not released a nightly.

I’ll check and let you know.

Firefox reality is 1 years old. And is sadly not the best XR browser out there. If you want to paste the stacktrace I might be able to help debugging this.

When I debug, there is no error in the console.
After clicking the xr glasses button, the loading icon is displayed for a short time（about 100-300ms）, and then around turned to dark。

Just to keep updating - there seems to be an error in firefox when binding the session’s request animation frame. It claims we are not running the render loop using the requestAnimationFrame of the active session, but that’s wrong.

I’ll see what we are doing different in 4.2 and try to come up with a solution for firefox. Will update here.

So! found the issue. It’s a firefox issue, but I have a fix for it - [XR] fix rendering in Firefox by RaananW · Pull Request #11631 · BabylonJS/Babylon.js (github.com)

It will be available in the next nightly (after being merged)

I would still not recommend firefox reality, as it has other issues that we simply can’t resolve (because of the version of the specs and the lack of updates)

thanks, the version of v5.0.0-alpha.64 works fine in my pico neo3!

This firefox reality browser is indeed not as good as the browser(based on chromium) in ocules, but there are no other options in this device…
Thanks very much for your contribution to this device :smiley: :wave: :+1:
