I used the instructions in the AR Course to create a simple game using the AR triggers. My targets and my overlays are still images. I set up my Targets with Vuforia and they come up in Aris Editor under "Which AR Target." My Media is also showing up correctly under each AR Target in the Trigger panel. But when I play the game, the overlay doesn't appear. I tried both the Scanner and the Augmented viewer. When I view the target with the camera in the game, I see that slight in-out shifting as if it's "looking" for the image, then the Continue button pops up. When I click that it goes to the correct screen, but no overlay image has appeared. I have several Target images I'm trying it with, all rated 5 stars by Vuforia. Are there any additional steps I need to take to get it working besides what's in the online course? Also, sometimes when the game opens the scanner I get an Error screen that reads "INIT_default" and I can OK.
