I'm testing Vuforia because I love the AR idea. I've got it working with an Image Target so far. However I just downloaded Unity 2017.3.0p3 and cannot get Ground Plane to work.
Image Target works in both, my computer cam and Huawei P9, but Ground Plane does not work in neither of them. I'm using the same settings I'm using in Image Target (even the same project). So Key and everything else seems to be set up properly. I know it won't probably work in my Huawei P9 but I was hoping for it to work on my computer at least.
