Extended Tracking Error

Hi,


I am contacting regarding an issue within your Unity Examples specially the Extended Tracking one.


Samples work fine for me otherwise the scene named "Image Tracking - Extended Tracking".  It crashes at the moment when target found. 


When i try to activate the Extended Tracking option in any of the other simple scenes it also crashes at the same moment.


Here is the Console log for that error:-

" Error when updating extended image tracking quality!

UnityEngine.Debug:LogError(Object)

Wikitude.<>c__DisplayClass40_0:<UpdateExtendedImageTrackingQuality>b__0()

Wikitude.TrackerManagerQueue:Execute()

Wikitude.TrackerManager:Update() "


I am using Unity 2018.1.6f1 and Unity 2017.1.4 and tried on both of them but noway. My current version of Wikitude SDK is 8-0-0_8-0-0_2018_07_06_09_00_51


Your quick reply is really appreciated as it is an urgent issue regarding choosing Wikitude as my company's core SDK.


Thanks in advance



Is it a consequent of not using a Unity version 5.x , and using a newer one ?

Hi, 


We weren't able to reproduce this issue. Using a newer version of Unity should work, except for 2018.2, for which we'll add support in the next update.

On what device does this issue happen? Does it also happen on other devices as well? Is there anything else in the console log that could indicate an error?

Was the project created by you, or did you use the one provided in the download package? If the project was created by you, can you also try the one provided?


Thank you,

Alexandru

Yes . Im also having the same issue

Hi,


Thank you for reporting this issue. Which error are you getting, exactly? "Error when updating extended image tracking quality!"?
Does this happen in the editor, or on the device? If it's on the device, please let us know which devices you've tested and if it's happening on all of them.

Did you also try our sample project, without any modifications? Does it happen there, as well?


Thank you,

Alexandru

It happen at the time of emulator in Unity and it gives 

"error when updating extended object tracking quality"

And after deploying in the device, no tracker is found

It happen on editor, i dont try on device. It's only with my own image on New scene. It works with the sample project with image sample but not with my image. My image doesn't have good tracking rate, but good rate of quality (2 star)

Hi,


For better tracking performance, I would recommend trying on a device, as the libraries for Android and iOS are better optimized. If you are building for Android, please make sure to enable 64-bit builds, otherwise the performance might also suffer.


I will also have a look at the error you're getting, but it shouldn't happen on a device.


Best regards,

Alexandru

Hello,


thanks for your reply. For option "enable 64-bit build" you mean the ARM64 in player settings? Because in build settings i have 32-bit and 16-bit option.

Weirdly tested it on another PC and still the same error, but worked fine on a third PC. All those devices have the same unity version and run your example project directly. I have tried to use one of the failing devices to build an android app and the app worked fine. Really confusing!

Hi, 


Which version of Unity and of the Wikitude SDK are you using?

Is the device you are deploying to also a UWP device?

Do you get any error messages from the device when this is happening?


Thank you,

Alexandru

Hi, 


Is the issue happening when pressing Play in the editor, or when building and running it as a UWP application?


Thank you,
Alexandru

Hi,


Yes, I mean the ARM64 setting from PlayerSettings -> Other Settings -> Configuration -> TargetArchitectures. If you see that the ARM64 option is greyed out, please make sure that the Scripting Backend is set to IL2CPP instead of Mono.


Best regards,

Alexandru

Hi,


Like Naveen, i meet same problem. I'm using wikitude SDK 8.10 on Unity 2019.2.14f1. 
I use imageTracker with my own image (2 stars). When I check "extended tracking" i got this error.


Thanks in advance.
