Got a cool scripted animation working on the font mesh level with TextMeshPro. (Pre-Vuforia - just main camera.) And then, it would be so neat to import a vuforia image target and augment that... except... shader errors have become the death of me in the past 12 hours :-\ Works in editor. Doesn't work on device. Black camera screen issues...
