Question AR Foundation and iOS - Lighting issues, disappearing/flickering objects, content placement, etc

Hi, I've been working on a project with Unity 2020 and AR Foundation for the iPad Pro 2020. There are a few different issues I'm stuck on that I could use help with

1. Lighting looks great in editor but looks dull and much worse on platform

2. On platform, when I moved the device around, objects flicker or pop in and out at times

3. I'm using ARSessionOrigin.MakeContentAppearAt for placing content based on the user's preference and orientation. This seems to be moving the camera around in an unexpected way. What I see as "forward" through the device is not what Unity thinks is the camera's transform.forward. I'm trying to use that to allow the player to move forwards, but it doesn't seem to work properly. The transform.forward seems to point in a different direction based on how the content was placed using MakeContentAppearAt. Not sure what I should be doing differently.

4. One thing I'm trying is to use AR occlussion to allow the user to take a photo (screenshot) of someone or themselves with some AR content next to or behind them. This works, but the image quality of the person looks very bad - like the camera feed is low resolution or something. Plus the occlussion quality isn't too great for this. Just wondering if there's anything I can do to make this work better.

In Editor:



On iOS : You can see the lighting quality difference as well as objects against the walls have disappeared leaving only shadows. They flicker in and out as I move the device around.

 

Can anyone help with this, especially the lighting issues which seems like some sort of bug?

 

Could you please tell me what SRP you use? A built-in one or URP?
In the case of URP, please check that you've assigned the URP asset to all Quality levels of your project. Please see the last screenshot:

Hi, thanks for your suggestion. I had already done the first few steps before, but I hadn't assigned the URP asset to all quality levels.(I am using URP btw)

I've done that now and tested again and visually nothing has changed. The moment the scene loads, for a split second I see the correct lighting and then it immediately reverts to the more dull and washed-out one you see in the screenshots above.

Is there anything else that comes to mind that you recommend I should check? Thanks again
