I am using the vuforia in a Win10 PC UWP. My usb camera has high resolution. But when I use it in UWP vuforia , the video background texture only have low resolution. I try to modify the file "Assets/editor/QCAR/WebcamProfiles/profiles.xml", but it only work in Unity Editor. After I built the UWP App, it haven't work. How I increase the video background texture resolution?
