It looks like if I have both the regular and the ARCamera active when I build and deploy the ARCamera will show static when I toggle from regular cam to ARCam... (the regular camera is set inactive)
Is there a way to toggle at runtime between AR mode camera and a regular camera in Unity
To essentially toggle between two cameras I attached two camera scripts to one camera. One being the TrackerScript. Then I enabled and disabled the other script as necessary. It required a bit of fiddling but it works well now.
My goal was to let them use a different camera interface when a trackable wasn't present so it may not apply to what you are trying to do.
