I downloaded the Google Cardboard project and exported it with the Android Free version. I did read that you need Unity Android Pro right? However, the free version of Android worked and the Google standard Cardboard App was just perfect. However, I'm now creating my own application and having two separate cubes with a panorama photo. I have both of them set in a layer and per camera defined to not render a specific cube. To be more precise, I have "Cube Left" and "Cube Right" both in a separate layer named: "Eye Left" and "Eye Right". The left camera is only rendering layer "Eye Left" and the right camera layer "Eye Right". When I publish the application and run it, I see both cubes being rendered in both cameras. Am I doing something wrong or is Camera Culling Masks not supported in Android Free? I do have Unity 4.x Pro, and when I run the game in the editor, both cameras render only there specific Cubes and not both. It's like I smell a Unity Bug here... correct me if I'm wrong.
