Part of image targets tracked but shown black screen

June 13, 2018 - 12:28am #1

Hi everyone! I really need some help with my AR project. I’m making a surrealist AR photobook. I have 35 photos as image targets in my book and same amount of videos. After I export it to iOS(iphone 7, 11.4) only half of my videos will show up and the rest will be black screen. In Unity i placed all the image targets under one AR camera and it runs smoothly with webcam. I optimized my image targets to around 30KB each, and video on average 1MB each.  No matter how I compressed the file size, or only build it with 17 image targets, only 15 image targets would be recognized, the rest are black screen. My complete app size is about 130MB. Please let me know if this is a bug from Unity or Xcode and how I can fix it please. Thanks a lot!!

For reference, I’m using Unity 2018, Vuforia 2017.3(The newest for both) and Xcode 9.4 for this project
