First of all: I have Vuforia 8.3.9 installed on Unity 2019.2.8f1. It's a fresh installation of Windows.
I tried to create an ARCamera on the project. When it's running, I can see just what the camera in 3D viewport is seeing.
ARCamera has a VideoBackground child game object that, in the material preview, is showing the webcam feed.
I also get an error saying "Unable to start ObjectTracker. Your hardware many not support it".
The webcam is an integrated, generic webcam
I'm kinda lost and I don't know what to do. I think this is something that happens to many people because I saw people complaining on other forums (and even here!) and coming up with various solutions that turned out good for them but didn't for me. Is there some step-by-step troubleshooting for this?
