Issue with developing for Vuzix M300XL: Exception on 0_camera_thread

Hello there,

I'm facing a problem while testing an app I've developed for Vuzix M300XL on Unity 2018.4.4f1 and Vuforia 8.3.8.

The app suddenly freezes and crashes upon starting a new scene that starting the ImageTarget scanning. The problem isn't always producible at the same scene, sometimes the scene work just fine.

The logfile as follows:

Disabling Stereo rendering

October 14, 2019 - 3:09am #1


I'm trying to simulate AR in my Oculus Go by mirroring the Unity play mode to my device using ALVR. Each eye gets the same image from my webcam, but Vuforia renderes two different images for my augmentations. That makes the augmentations look 3D, which is not wanted, because they look like they are floating. How can I disable this stereo effect?


Many thanks in advance

AR+VR for Phones+Viewers

September 19, 2019 - 11:53am #1

I was developing an AR + VR app for smartphones and I have seen the warning that support for VR and stereo rendering will be maintained for Hololens only.


Are there other ways to use Vuforia Engine to build AR + VR mobile apps?

why slot-in viewer devices are not supported?

August 16, 2019 - 1:45am #1

I saw that slot-in viewer type devices are not supported in the near future.
Is it real that it won't support no longer?
I cannot understand about this...
it is useful to make prototype of vr and ar glasses..
please re-consider and not terminate the technology for the future.
Do not lean too much to MS. MS is good company but it is not fair.

How to set world center mode to camera??

July 31, 2019 - 1:12am #1

I am developing AR app for shadow creator action one with unity 2018.1.

The tutorial says I should set world center mode to "camera", but I don't have this option. It only has device, first target, specific target.

Do M300XL support model target in Vuforia Engine in unity?

June 20, 2019 - 1:27am #1



May i know M300XL support model target in unity?

I had built an android application and i able to see the 2D guideline on it, but once i placed it on the actual object. Model target is not working as there is no 3D model appear on it.

While i use mobile device and webcam, the model target is no problem with it.

Unity version => 2019.1.2f1

Vuforia version => 8.1.7

Visual Studio version 2015,  .Net Framework 4.6.01586

Thank you and appreciate for the reply.
