Hey, it's my first time creating a multi target. I'm currently trying to upload images to my cuboid multi target, but when I try it just says that the upload failed. No specified reason. My images are 8 bit JPG, 15x15cm each, the cuboid dimensions are also 15x15cm on each side.

What's going wrong? Can someone help me?

I am currently using MTG 10.9.3.

I am continually getting a 504 error during simplification:



Simplification failed with the following error:

Unspecified error during upload: 504 "upstream request timeout"

Do you want to restart simplification again?



I have restarted numerous time at this point.

I have also started from scratch again.

What is up with this?

Are your servers having issues?

Problemi con download database

July 15, 2022 - 9:40am #1

Buongiorno a tutti. Ho da poco iniziato ad immergermi nella A.R. ma ho già riscontrato un problema. Quando provo a scaricare il database mi viene fuori questo messaggio: "Non ci sono destinazioni attive selezionate per il download. Controlla lo stato dei tuoi target e riprova". E tutto attivo, il target e selezionato. Ho provato più volte a rifare il target e il database ma il problema sussiste da all'incirca una settimana. Chiedo a Voi un aiuto su come posso risolvere questo problema.

Cloud Recognition Vuforia Not Scanning

Unity Editor
July 4, 2022 - 11:53pm #1


I am trying to scan my Image Targets uploaded on the Vuforia Cloud Storage. I am loading my assetbundles from a JSON file which are present on the Google Drive. But whenever I build the app, it doesn't scan the Image target. However the same code was working few weeks back now I need to add some more features but unfortunately I am not able to perform scanning.
