I have upgraded my AR app from Unity 2018.2.18f1 to Unity 2021.1.13f1 and also upgraded the Wikitude package from 8.5 to 9.9. Using the same C# Visual Studio scripts and having no errors or warnings. When I build and run the app on my Samsung SM T835 tablet, the device the builds successfully, but when it runs on the tablet everything is fine except that the grid for the Instant Tracker Initialization is not there anymore. So I think the tracking never starts. The same app is working perfectly when I run it from my old version before the Unity upgrade. I have checked the migration notes and the documentation and found no clue yet. Do u have any solution for that problem?.
To reproduce the issue:
-Build & run the AR app
Thanks in advance,
So to make my question more clear. My application has a grid which is for the user to confirm the initilization of the Instant Tracker. If tracking can be started the grid turns from blue to yellow and then when the user confirms that initialization is done by pressing a button then it turns green and becomes the origin of augmentations with tracking started. Here in the screenshots below the different stages of the grid are shown. This was working perfectly fine with Unity 2018.2.18f1 and Wikitude 8.5. After the upgrading AR app with the same code and configurations to Unity 2021.1.13f1 and Wikitude 9.9. The grid disappeared although no single line of code has changed and there are no errors or warnings. Do you have any idea what might be the reason for that? or How to fix it?.
Thanks in advance
Do you have the same issues when using the sample project provided in the package without any modifications? The instant tracking sample also contains a grid and this step should helps us narrow down where the issue is coming from.
I don't have the same issues with the Instant Tracking sample and it works normally except that I get that error "Platform suppport query failed. Running without platform assisted tracking support". The problem is there in my app which was not changed and was already working with Wikitude 8.5 and Unity 2018.2.18f1. Additionally, I tried to use the Unity version 2020.3.2f1 mentioned in the Wikitude Unity Plugin documentation and Wikitude 8.5. This resulted that my app worked there but the grid is always yellow in the Instant Tracker initialization stage meaning that tracking can be started anywhere. Also sometimes after tracking is started and the world origin is defined the tracking is lost and the augmentations disappear although this never happened with my app before the upgrade.
Thanks in advance,
