Unity + Vuforia freeze on play

August 15, 2019 - 11:03am #1

Hi,



When I place AR camera into Unity scene and hit play, Unity just freeze. Sometimes it open camera, but usually it freeze.

I have Unity 2018.4.6 and Vuforia 8.3.8 . I tried with different version but same problem.

I also tried adding my webcam profile (Program Files\Unity 2018.4.6\Editor\Data\PlaybackEngines\VuforiaSupport\VuforiaResources) but nothing better.

I think changing compatibility mode for Unity exe fixes this.

Hi,

If it worked before, the issue could be related to a 3rd party software which had access to the vuforia/unity files, for ex. like an antivirus.

Does your scene contain other GameObjects besides the Vuforia AR Camera? and does it work without the AR Camera in the scene?

Thank you.

Hi,

I've tested with Unity 2019.1.9f1 and Vuforia 8.3.8, with external usb camera ( c920 logitech) and the integrated camera from my laptop and I was *not* able to reproduce the behavior. Also I've used the Vuforia Core samples as test project.

Could you please confirm the following to have a better understanding:

  1. Are you using an external webcam or the integrated webcam of your laptop? For external usb camera please confirm the model.
  2. If you go under VuforiaSettings-> Webcam is your camera being picked up?
  3. Does your camera work outside of unity?
  4. Did it work before?

Thank you.
