Unity 2019.1.12, wikitude plugin 8.9.0, device pocophone f1 android 9(problem also reproduce on samsung a30). We using simple instant tracking from examples. I didn`t upgrade plugin. Steps for reproduce you can see in video in statr message. I build samples, and have same issue(almost) in my case model doesnt dissapera. In samples - model dissapeared. Video below


Hi Maksim,

We could reproduce the issue and will create a Jira ticket for the next release.

Thanks and greetings,

The issue is happening because ARCore is losing tracking when pausing and resuming the application. This doesn't happen all the time, and can be improved by having more lateral movement with the phone, which will make ARCore track better.

Since this cannot be completely eliminated, I would recommend that when this is detected, you ask the user to reinitialize tracking.

Best regards,
