I have an odd problem. I've been messing around with this for days now without a problem. I just added a second Image Target to one of my projects and increased "Max simultaneous Image Targets" to two.
Built & Ran it and where normally I'd see what the camera was seeing I was only seeing grey. I thought to myself "dang, that sucks that they don't put the camera image through when simultaneous is higher than 1" little did I know.
After messing around a bit I wanted to see the what the camera was seeing again so I set simultaneous back to one. Still a grey background. I loaded up one of the other projects that was still installed on my phone from earlier that was working before. Still a grey background. Reboot the phone. Still a grey background. Did a reimport all. Still a grey background.
Any help is appreciated.
P.S. It is a G2.
It's working now! Thanks!
Gonna name my projects;
Bad Project: The one I originally had the problem with. It just has some basic models and two ImageTargets.
Original Project: One I'd been using for awhile without a problem. I have made changes to the TrackerScript.cs on it and it does have particle effects.
ImageTargets: I created the new project and imported QCAR-ImageTargets.unitypackage.
After creating ImageTargets it didn't work (saw the pots though). Changed to OpenGL ES 2.0 and it worked!
Went back to the Original Project and it still had the grey background. Same for the bad project. Bumped the bad project up to OpenGL 2.0 and it worked.
I'm glad it is working again although I'm awfully curious what could have happened to retroactively break apps that were working before.
