Occlusion not working on latest ardk versions

Bug Reports
1
  • Issue category: Real-time Mapping-Depth / Occlusion
  • Device type & OS version: Android 15 (I’m using a Nothing Phone 2a)
  • Host machine & OS version: Windows
  • Issue Environment : On Device
  • ARDK versions: 3.16 / 3.15.1 / 3.15
  • Unity versions: 6000.0.58f2 / 2022.3.62f2

Bug reproduction steps:

  • Create a new Unity project with recommended version (6000.0.58f2 or 2022.3.62f2) and with URP or built-in
  • Follow the doc to setup ARDK (link) with ARDK 3.15 or later + additional steps if needed for URP
  • Try to use occlusion with AR Occlusion Manager from AR Foundation or display depth as shader (link)
  • It works in editor with “Niantic Lightship SDK for Unity Editor” but doesn’t work on Android build

I tried a lot of different setups with both recommended versions for Unity, and with both URP and built-in ; but the problem seems to come from the ARDK’s version. I tried version 3.13 and 3.14 and it works as expected so far.

It would be great to have a fix since 16 KB page size support for Android is only available from version 3.15 or later.

Hi Flavian,

Any chance you can also send over a recording of the occlusion failing to work so that I can test and compare with what you’re getting?

Hi Jesus,

Thanks for the fast reply.

I realised when recording that this bug doesn’t happen all the time on 3.15+ versions.

At first, when testing I thought that occlusion/depth simply never worked on these versions since I was only testing right after creating the build. Now I see that the bug is related to the app focus.

On the recording we can see that the bug occurs when the application loses focus for version 3.16.

Version 3.16:

I also tried the same reproduction on version 3.14 to compare and we can see that the same bug never occurs.

Version 3.14:

I hope this helps.

Thanks for sharing. I’ll show this to our developers so that they can take a look. I’ll reach back out to you if I require any additional information
