[Unity 2017.1.0f3 - iOS] Black Screen When Using VR Mode #271

Closed dustinkerstein closed 6 years ago

Cross listing this issue here since I believe it's likely more of an iOS GVR SDK bug vs. Unity GVR SDK bug as I don't actually have the Unity GVR SDK installed and I can still replicate this.

FYI - This is still reproducible on Unity 2017.1.1p3 and the current 2017.2 beta

Dustin, do you any additional details which might help us track down this issue?

I'm not able to reproduce the black screen. I just tried building a default project using both Unity 2017.1.1f1 and 2017.1.1p3. Both apps run correctly on an iOS 11.0 phone (A1687 - iPhone 6S Plus).

The only Unity settings I changed were:

Interesting. Try with the "None" device loaded first and then load the "cardboard" device after startup. I'll try to replicate on a simple project tomorrow morning, but that might be the trick.

The only Unity settings I changed were:

  • Player Settings > iOS > Virtual Reality Supported: enabled
  • Player Settings > iOS > Virtual Reality SDKs > cardboard
  • Player Settings > iOS > Target minimum iOS Version: 8.0 (was 7.0 by default)

Thanks again, Dustin. It seems Metal was set as the default Graphics API for me, which is why I wasn't seeing the issue.

I was able to reproduce the black screen by setting either OpenGLES2 or OpenGLES3 as the first Graphics API:

I just walked through the Google VR SDK for iOS getting started guide and did not encounter any issues with a black screen.

Closing this issue, as https://github.com/googlevr/gvr-unity-sdk/issues/661 appears to be Unity specific.
