Hi all,

Please use this thread as a place to consolidate feature requests for the QCAR SDK. If there is something missing that is holding back your development efforts, we'd like to know about it! If you're having trouble with an existing feature and would like more sample code to help you get started, we'd like to know about that too.

Looking forward to your input, thanks!

What is the latest version of Unity that supports a Vuforia 4 license?

August 31, 2021 - 4:49am #1


We have a legacy project which started in 2016 with a Vuforia 4 Classic license that was purchased. 

This project needs to be updated, but Apple require that we use a later version of Unity and we're unsure if this will even be possible.

Can anyone help me find out what is the highest version of Unity that still supports a Vuforia 4 license? Hopefully it's the latest and that solves a big problem, but we assume it's not.

Front Camera

August 25, 2021 - 12:33am #1

Hi everybody,


I was wondering why the use of the front camera was depreciated and if there is any technique to use it despite all. It can be usefull in many project so I don't really understand the choice of Vuforia on this...


Thanks in advance.

Does anyone have any idea on when and/or if Vuforia plans to incorporate Color as a variable for Image Recognition?

Topic solved

Hi all, i would like to check if i am developing an AR app (mapping target to video file) locally (Not going to publish to Play store or App Store). do i need to purchase any license if i am going to distribute locally to a group of people ? 

As this project is still in prototyping thats why for now only distributing locally and not in play store or app store.

Inconsistent Feature Exclusion Buffer border around Image Targets when uploading to Target Manager

August 13, 2021 - 8:54am #1


An issue I have discovered over time is that the image targets when uploaded to Vuforia Target Manager are not consistent with the % border that is used. It seems that this feature exclusion buffer hovers anywhere from 4% on each side of the image to upwards of 10%.

Invalid Image Target file format

July 14, 2021 - 8:31am #1

Sooo long story short, I really want to use some kind of qr code as image target.

After generating and downloading these image targets and uploading them back to the database, the format is invalid. I tried different qr codes and also converting them. But actually nothing really works.

Using other image targets works, but I really want to use qr codes. Anyone some idea what I could do or how to convert them properly to get it to work?

Simultaneous use device database and cloud

June 26, 2021 - 4:12am #1

Hello, how can I simultaneous use device database and cloud? I want my Image Target to use two databases, or maybe I have to create two Image Targets, one for Cloud DB, one for Device DB. How do I do that?
