Experience inconsistency in adding markers to cloud database

March 10, 2021 - 1:02pm #2

Dear Vuforia Support,


We have an automated test that adds several imagetarget / markers to a cloud database. But after the update last (maintenance Vuforia) we experience that some of the markers can be added and some result in an error.

Also cases that the TargetID can not be found but we see the targetId in de web portal of Vuforia in our cloud database.

Any idea if also other developers experience this?

Depth Scan

March 7, 2021 - 9:03am #2


Is there any way to scan depth dynamically just like AR Core? I'd like to generate meshes for physics simulation in my Unity app, as well as for dynamic object occlusion.

See what I mean in action here: .

Engine key

February 24, 2021 - 8:27am #3


We used Vuforia for the first time last year. We entered the key in our apps.

Will this key change when we renew our current contract? Or will the key remain the same?

If it's another key, than we need to update our app and push it back to the stores...


Kind regards

How do I make a model change when two targets come in contact

February 4, 2021 - 10:55pm #1

I am building a chemistry game where you can mix chemicals by putting two or more cards together. How do I make the model above a card change if two cards come in contact with each other?

Vuforia::init takes long time on restricted network

October 2, 2020 - 6:27am #11

Hi, I have an application that init and deinit a lot when switching views and I encountered a problem if the network that the device connects has restricted (outgoing/incoming traffic blocked) or no internet access. 

From what I was able to establish Vuforia::init takes ~10 seconds to return 100 result with blocked ethernet connection while with unblocked or no connection it takes ~1 second.
