Finally getting a chance to get back to my app development with school ending soon so I downloaded the Unity extension to get that on the road. Unfortunately, I seem to be having problems adding the required objects to the scene. Neither the ARCamera, FrameMaker, or ImageTarget prefabs have any info associated with them and refuse to be dropped into the scene. I've tried it on two computers now with the same results so I must've missed something.... Anyone else hit this problem?
