I am working on a Mac and trying to get an iPhone app working. I finally got the camera to come on when previewing on a mac, which required updating to EasyAR 2.3.0 and switching the graphics to OpenGL Core. I don't get an invalid key error when opening on a mac, but once I port it to my iPhone it comes up with the Error: Invalid Key message. I tried creating a new SDK Authorization using the 2.0 license key, and I tried using a previous SDK Authorization with the 2.0 license key. I am sure that I have Bundle ID and License Key in the correct places in Unity. What else could be going on?
Alright, I ran through things again with a new project. I was able to get it to recognize the key, but it still doesn't bring up the camera. All I am seeing is the horizon when I open the app on my iPhone. It does however open the camera and recognize my target just on my Mac.
Here is a video of me creating this last project, which I hope is helpful in troubleshooting: http://youtu.be/PRNC3R_17wo
