VUFORIA HAVING ISSUES WITH HOLOTOOLKIT

Hey fellas!
After trying some basic recognition with Vuforia through Hololens, I tried adding Holotoolkit to the project so I can add some holographic features.
I had no problem at firt but during the debug session, I found Exceptions thrown continously(a null pointer exception in the callback).
Since the Holotoolkit is the only new thing, I decided to delete it and all that was added after the Holotoolkit. The problem persisted and I had to delete the project and start it again since it is of no big importance.
the new project is doing well and is without holotoolkit.
If anyone had the same problem or have any suggestion I'm here waiting for you.

  • I'd also like to do this in the future, hope there's a fix! (Still trying to get Vuforia's HoloLens sample working, though...)

  • We are using Holotoolkit and Vuforia though we may be on a different version than you.

    What is the exact error you are seeing?

    hi! in the end i downloaded a new holotoolkit as reading your comment made me think that maybe my version was somehow corrupted.
    I'm not having any error so far. All I need to know is how to make things work.
    I'm wondering if you can share me some knowledge.
    As for now, I succeded with object recognition and holographic display after a recognition.
    I was just wondering if there is anyway I can pause object tracking so I can use hololens' Gaze and other feature. So far I only tried keeping the holograms renderer on even if the target is not there anymore. I was just wondering why my cursor doesn't appear even if it's the target's child. I'm kinda stuck in here for days,
    Hope you can help me with it.

    did you succeed?
    In case, I only put the sample scene on unity and made a build. I had to do nothing important. maybe just create and add the app license.

    Not yet! I'm going to try again though, with the latest versions of the toolkit and vuforia. Last time, I had a lot of errors trying to run the hololens sample scene.

  • @sbagchi yeah try again.
    When I tried I had to delete the sharing folder from hololens,
    As I observed, the errors we're not related to Vuforia itself but more on two scripts or materials having the same name. Try reading the console and what it says. It really is of help. If needed, try deleting or renaming objects in the holotoolkit and you should be fine.
    Try vising this site, it helped me:

    Thanks. I was able to get the HoloLens samples etc. working, but haven't yet tried adding in the HLTK. I'll take a look at the link!
