Area Targets is not compatible with Hololens2 after update

[MaheshXr29]

Summarize the bug: I have been working to create a sample project using Vuforia Area Targets ,It was working flawlessly for a while but all of sudden area targets is not all getting detected.

Observed problem I have tried various solutions that has been mentioned in different forums and I think version of vuforia is reason for this issue. First we used vuforia 10.15 version with this version it is working good , but all of sudden it stopped working , even I tried updating vuforia package versions but no use . Similarly my friend is also facing same issue, when updated vuforia version to latest(10.17) Area targets stopped working.

Expected result Area Targets should be detected as before and the content in the area targets to be positioned accurately as it was in android platform.

Other observations Taking too much time to detect Area Target

Affected platform:

• Workstation OS: Windows
• Platform : Universal Windows Platform
• Device : Hololens2

Hello,

Can you please provide the following clarifications:

1. Which version of the Area Target Generator was used for generating the device databases included in the app? Note that for optimum performance and compatibility, we recommend using the same version of the Area Target Generator as the Unity Extension (i.e. 10.17.X).
2. Has the scanned environment changed? Has the placement of furniture or objects within the space been moved or removed? Area Targets are robust to changes, but there is a threshold for which too many changes will cause the space to no longer being detected without rescanning.

Thanks, Vuforia Support

@zoro-the-lost, please create a new bug report as this sounds like a separate issue. Thank you.

Hello,

1. I had used Vuforia Creator Ios Mobile app version(10.17.2)
2. There are some environment changes but not major just added 2 objects that too smaller ones and we had an older scan which is being used for an mobile is working fine .

@MaheshXr29 thanks for the response. Seems unlikely that the issue would be related to device database compatibility or changes in the scanned space.

Which version of the Unity Editor are you using? My recollection is that we had recently bumped our minimum supported version to 2022.3.5f1+ for Engine 10.17.

Lastly, have you tried testing the device database in the latest version of the Vuforia Creator app?

Thanks, Vuforia Support

2021.3.24f1 is the Unity version I am using. I tried the device database in the latest version of vuforia creator app , It is working and I have one more doubt, since you mentioned minimum unity version for vuforia 10.17 is 2022.3.5f1 , I am using vuforia model targets in my another project which is on unity 2020.3.47f1 and vuforia 10.17 and It is working good but my area targets project on 2021.3.24f1 is not working ,I used same vuforia version in both projects . what could be the reason for the issue with area tragets. Should I need to change some settings in the editor ?

Hello,

Great to hear! This means that the issue is not related to the Area Target device database.

Should I need to change some settings in the editor ?

I don't believe that this is the case. Since you're using the same Engine version (10.17), that setting would be set in both projects.

Since you've proven this issue is not with the Area Target device database, I would suggest you try the same in our Area Targets Test App for HoloLens.
