The marker shows, but camera isnt working. unity 5.1.0p1 Vuforia 4.2.3
Ive tried changing around settings, sometimes I get a split screen where half screen reacts to light, and half is black; the screen is split in two equal triangles testing on note 4 Most of time the whole screen is black.
In both cases when the camera see imagine it shows marker, but it is very laggy and freezes if moved too much.
I dont know much about game development so if there is a post with basic unity/build settings please link.
