I couldn’t get it to do anything besides select a photo. It showed the ar startup “move phone around” message. I tried Measure and that was working fine so I tried your app again. No luck. iPhone 12 mini (in case relevant)
Hmm interesting, does the "move phone around" message ever go away? I'm working on tuning it still, but you might have to walk around and pan the camera around the area a bit more (looking into optimizing this more in coming updates). It's currently setup so ARKit can calibrate itself during that time, and that message should disappear once it's done calibrating. Once it's ready, a message like "Tap on the wall to see your artwork" should show up
