Known issue: Vuforia 7.5.26 does work with .NET scripting backend on UWP in Unity

October 31, 2018 - 8:57am #1

Hello,

A regression was introduced with Vuforia SDK 7.5.26 in Unity where using the .NET scripting backend will throw an exception when running a Universal Windows Platform build. This also includes HoloLens apps.

Please use the IL2CPP scripting backend instead, where this issue is not seen. We plan to fix this issue in an upcoming release.

Vuforia 7 HoloLens Samples

February 16, 2018 - 5:04pm #1

Hello all,

The HoloLens samples, both the Image Target and new Model Target samples, are now available at the following link https://developer.vuforia.com/downloads/beta. A recent patch for Unity 2017.3 has fixed a bug with HoloLens development, so please use Unity 2017.3.1p1 for working with HoloLens as previous versions will not function correctly.

These samples will also soon be available on the Unity Asset Store along with the rest of the samples.

Thanks,

Vuforia Support

Updated HoloLens resolution now available

March 21, 2017 - 9:39am #1

Hello,

A patch is available for HoloLens performance modes for Vuforia SDK 6.1 and greater. This change updates the "MODE_DEFAULT" camera device/performance mode to use the 896x504 resolution, as recommended by Microsoft for Vuforia computer vision algorithms. Vuforia's testing shows an improvement in detection distances on HoloLens when using this mode. The previous MODE_DEFAULT resolution can still be used by selecting MODE_OPTIMIZE_SPEED (1280X720). MODE_OPTIMIZE_QUALITY (1344x756) remains unchanged.

Deployment errors for Hololens

April 3, 2019 - 9:41pm #1

Hi! I've been trying to deploy my Unity project to Hololens using Visual Studio but I keep on getting "Exception Unhandled" errors during deployment and it stops the application.

I'm using Unity 2018.3.11f1 and Vuforia 8-1-7. I'm attaching a sample image of the Visual Studio error. 

Usually the errors are under "No Symbols Loaded", and the combase.pdb or basekernell.dll Unhandled exceptions.

Hi, 

 

There is no model target guide view showing up on HoloLens. I have tried to use guideview 3D from the options as well but it does not show up. Any solutions?

App crashes in one particular room

March 27, 2019 - 7:38am #1

Hello everybody it's me again ahah.

 

I have a really curious situation right now. I have my app, what is starting and working really fine in my office. But when I'm trying to start the same app in another room (let's call it room 1), after the Unity Logo, nothing happens. When i'm trying to close it and restart it, it seems like the app switched to stand by mode and doesn't want to start. I tried to use my app in 2 other rooms (room 2 and room 3), and it's working perfectly. It's only in the room 1 that the app doesn't work.
