Camera background is now gone after upgrading to ARKit XR 4.0.1

I just upgraded to ARKit XR 4.0.1 (with ARFoundation 4.0.2, Subsystems 4.0.1) and and now my AR Camera background image is blank. There's nothing coming in from the device camera.

I thought that perhaps there was a problematic setting in upgrading my currently AR Foundation project, so I started another from scratch (2019.3.8, URP). No luck. Same blank camera.

Anyone hit this and solve it or have any tips?

Thank you

 

And of course it's a checkbox.

Project Settings -> XR Plug-in Management -> iOS ->
I Had to check "ARKit" under Plug-in Providers.

I imagine the same is true under the Android tab when building to Android.

I found this by wandering through the ARFoundation-Samples project on Github and comparing it to my setup. I hadn't seen the Samples project before and really appreciate seeing a lot of AR scenarios/systems implemented. For example:

• Plane occlusion
• Environment Probes
• AR World Map
• And actually delaying the OS's camera permission request. I hate when apps launch with a series of immediate asks before proving the reason and value (FYI, they do it simply by putting the AR Session/Origin/Camera in another scene that's loaded post launch. Seems obvious now but hadn't thought of it and hadn't seen anyone talking about it.)

Glad I stumbled on the project via this issue
