Virtual (AR Content) Object Not hidden by real physical objects

May 4, 2022 - 2:23pm #1

I'm using the latest version of Vuforia and the suggested version of unity. Everything builds perfectly as an IOS app when I create an Area target app.

I'm doing a simple hello world cube. The problem is when using the IOS the AR content (the cube game object) is not being hidden by real physical walls. I have not seen anything addressing the issue anywhere surprisingly. Can't believe I'm the only one with this problem.

...and yes, Add Occlusion Mesh is checked.


Thanks in advance

Single channel tracking

I'm facing an issue and would highly appreciate your help.

When using a basic license and running the application simultaneously on two different devices, one device tracks the marker image while the other does not. Tracking works only on the device where the application was first launched. 

What causes it and how it can be fixed?

AR Camera shows White Screen

I made an App for Andorid with Unity + Vuforia, it was tested in 3 Android devices by now. In 1 of them (Samsung Galaxy S20) the App does not work, there is an issue with the Vuforia AR Camera a White Screen is showed instead of the rear camera of the phone. (See attached Image)

In the other 2 devices (Samsung Galaxy a52 and a Motorola One Fusion) the AR Camera works well, but after some time of use (like 5/10 minutes) it starts to work bad like slow or with freeze.

Model Target Generator naming problem

January 5, 2022 - 1:18am #1

Vuforia SDK Version: 10.3.2 -

Description with steps to reproduce: For creating a model target there are no limitations in naming but when you want to want to start a training you are not allowed to use special characters like "."
Normally this is not a big deal but there is no possibility to rename a model target.
=>You have to recreate the model target from scratch.

Please provide a feature to rename a model target or generate the same naming conventions for creating a model target as it is set for the database training.

Creating image targets at runtime throws error - "The target width cannot be 0 or smaller"

November 13, 2021 - 9:08am #1

Vuforia SDK Version: 10.2.5 -

Description with steps to reproduce:

I believe that creating image targets is broken on the latest version of Vuforia - 10.2.5

It works on desktop but I get this error on Android: Unable to set the RuntimeImageSource. The target width cannot be 0 or smaller.


Here is the code:


ImageTargetBehaviour test = VuforiaBehaviour.Instance.ObserverFactory.CreateImageTarget(TestTexture, 0.2f, "TestTexture");

The "TestTexture" variable is set in Inspector and is a valid texture.
