Hi,

I added Xcode Unity AR (with Vuforia) project to existing Xcode app by this project. I have few problems but I solved them all and my project is now building and running in real device. App works as before but when I try to select AR item from menu so my controller with Unity AR is pushed. I get blank screen (white screen). These are few lines from console log (that I think are related to problem):

More info about versions:

I tried to change many settings according to many forum posts that I found but nothing helps me. I am not using Metal (I am using OpenGLES3, I tried OpenGLES2 too).

Thanks for help

I have the same issue

lorant-csonka-ICE commented 4 years ago

Mine was actually resolved. It's working if I set up this order at graphic frameworks:

  1. OpenGLES3
  2. OpenGLES2
  3. Metal
