Black background when taking a photo in ar mode

Hi, so the issue is when I take a photo on my Note10(Android 11), the 3D astronaut appears with my background in AR, however when take do the same on my iPad(IOS 15.2), only the 3D astronaut shows up and my background is black.

I'm surprised to hear that iOS supports WebXR, is this actually what is in use here?

[Dean Jackson]

Yeah, this is a bit confusing. We don't support WebXR at the moment, especially on iOS.

On iOS this is using the platform native built in model viewer. The black background would indicate that the model viewer is running out of memory or that somehow user has declined the camera (I don't know if this is possible).
[e-mail]: could you go to Settings -> General of your iPad and describe what it says for Model name and model number?

I cannot immediately repro on iPad Pro 2015

[Kimmo Kinnunen]

In fact, I can repro it.
So the live model works ok, but taking a screenshot produces a black background.

[Dean Jackson]

Oh, now I see. This is the built-in AR viewer. It does appear to be a bug that it is not saving the camera feed when taking a screenshot. I've forwarded it to the right component.
