Hello good afternoon, i am trying to scan qr codes using unreal engine 5 and I can’t find much documentation about it.

I followed the steps on this page but I couldn’t get variations when showing a QR code on the camera.

the length is always 0 and does not print anything else.

I can’t use plugins like Zxing to solve the problem. I’m looking to generate a basic QR recognition app.

Hello,

UARTrackedQRCode is inherited from UARTrackedImage. I guess you have to define the images to track in the AR session configuration.

Hello, I was trying to be able to read the code and not directly recognize the image, previously I made an image recognition application, this is an extra requirement.

anyway thank you very much.
