Vuforia on Unity - Android (Half black screen)

July 15, 2015 - 2:30pm #1

Hi, Im Lucas, and I am new to vuforia.

I have unity 5.1.f1 I am trying to insert one of the  unity video playback samples onto my phone. I have activated the software, and when I run the app on my Samsung Galaxy Note 4, Half the screen is black. From the top right corner to the bottom left corner. From the other half of the screen it seems to detect color from the camera. It is just a solid color. No video playback no tracking. I am trying to work step by step. Not releasing a full blown build.  This does work on my friends iphone 5s.  So I hope someone knows what this is and can tell me how to fix it. :)  

Thanks for reading!

No one has responded to this and it is old enough that I am sure its been fixed, but I randomly came across this myself.

I resolved it, and it ended up being that I had my AR camera and some game objects sharing the same position on the scene (0,0,0) and the camera didn't have a rendering layer so it was rendering the underside of the gameobject. You can set a rendering layer, or just move the AR camera and it will stop this from happening.

1.

If you are using Unity 5.0.1 or 5.0.2, make sure to upgrade to at least to 5.0.3 or 5.0.4.

 

2.

If you are using Unity 5.1.0, make sure to upgrade to at least to Unity 5.1.1.

 

3.

Also, in Unity 5.1.x you need to check the Android Player Settings > Other Settings >disable the "Automatic Graphics API" checkbox and remove the OpenGL ES 3.0 from the Graphcis API dropdown list;

you need to have OpenGL ES 2.0 only included .

Hi,

I'm having the same problem. On my webcam my project works fine, but when I build Android project and deploy it to Nexus 9 my screen is half black and half is just one color. That doesn't happen when I have the same project running on Lenovo tablet. However, on Lenovo tablet I have another problem - it recognizes TargetImage and makes it's children visible, but the colors are strangly modified (e.g. I have white UI image and black text in my project and on tablet it's green UIimage and text is sometimes red, sometimes blue, sometimes yellow...)

Thanks

I had this, not sure why or what the cause was.  But there was something wrong with my ARCamera.  I removed it, recreated it and it worked fine

 

 

cheers
