Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

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!
