I've got an ARCamera and I need to get access to the background texture. How can I do that? I've checked the background texture access sample, but I was nothing useful in there; just UI handling code, OpenGL error checking and whatever the default ARCamera prefab has. Am I missing something? I've tried this one here but it looks awfully outdated and never gives me any valid image.
I'm working with Vuforia 5.05 and Unity 5.1.3.
