  • Hololens Grammar recognizer sometimes failing silently I'm having trouble with the hololens grammar recognizer. When I initially start my app and the room is quiet it works pretty close to perfectly. However if I'm demonstrating my app and there's a few people in the room the grammar recognizer will either have much more trouble picking up the commands or fail entirely and no commands will work until restarting the app. I can have 2-3 hololens in the same room and on the same build and 1 will sometimes not work and I'll get the following error...

  • DllNotFoundException: openvr_api Hey everyone,

    I'm having an issue in my builds that is making them completely useless. I've searched everywhere and I can't seem to find any information on it. It makes it so the HMD displays nothing and the camera just stays at it's start position.

    I'm using Unity 5.5.0p3 by the way, any help would be appreciated.

    Here's the error:

  • [Solved]TriLib on Hololens, folder access I'm trying to use https://assetstore.unity.com/packages/tools/modeling/trilib-model-loader-package-91777 to load models at runtime. The idea is to have a json file containing the file names and additional info and the models as fbx.

    Ideally I want to use a folder that is visible when you connect the hololens to a PC via USB. So I am trying to the "3D Objects" folder. My app has permission to access that folder, I can load the json file just fine. Now when I try to load a fbx...

  • Replace original OpenVR SDK with its modified version Hi everyone!
    I had added some functionality into OpenVR SDK source code and built my version of openvr_api.dll.
    Now I wish to run my Unity project via this OpenVR dll, but I've stuck on thought where to place that dll?
    I tried several places:

    - Installed SteamVR directory: failed due to SteamVR uses proprietary version of openvr_api.dll (SteamVR crashes)
    - Unity\Editor\Data\UnityExtensions\Unity\VR\ directory: failed, it seems that Unity just ignores my dll there.
    - Plugin folder of...

  • SteamVR Input Bindings not recognizing Oculus Touch Controllers I'm trying to setup my touch controllers with SteamVR and bind some actions so that I can pick things up with them. When I use the SteamVR Prefab I am able to see the controllers, and the SteamVR Overlay also shows both of my touch controllers. However when I go into the SteamVR Binding Menu I do not see my touch controllers showing up. Does anyone know why this might be?



  • Let users create their own virtual tours Hey, I'm pretty new to Unity and I'm working on Virtual Tour using Oculus SDK. I want to create an application that allows users to view any virtual tour.

    So I want users to create the tour by placing objects representing the view at some point, let them specify a transition effect, put control objects into the view for transitions between views and somehow let them connect all views together. The user should be able to export the tour into some file and then view the tour by loading this...

  • How to lock X and Z axis of gyroscope? Hello Guys
    I'm working in a project in wich I need to obtain the data from gyroscope, more speciffically the Pitch axis of rotation on the smartphone. The problem is when I rotate more than 90 degrees in another axis, the Pitch attitude jumps from 270-360 to 0-90, where i have no data assigned.
