The black screen issue in Unity AR apps can occur due to various reasons. It might be a problem with the AR foundation, camera settings, or even the app’s code. Identifying the root cause is the first step towards resolving the issue.

Common Causes of the Black Screen

Here are some of the most common causes of the black screen issue in Unity AR apps:

  • AR Foundation not initialized properly

  • Camera settings are not configured correctly

  • AR Session is not started or is not active

  • Graphics settings are not optimized for AR

  • App code has errors or is not compatible with AR

Diagnosing the Black Screen Issue

Before jumping into solutions, it’s essential to diagnose the issue. Here are some steps you can follow:

  1. Check if the AR Foundation is initialized properly. Ensure that the AR Session Origin is set to ‘World Origin’ and the AR Session is started.

  2. Verify that the camera settings are configured correctly. Make sure the camera is enabled and the resolution is set to a value that supports AR.

  3. Check if the AR Session is active. If it’s not, try restarting the app or resetting the AR Session.

  4. Optimize your graphics settings for AR. Ensure that the graphics API is set to ‘Auto’ and the rendering path is set to ‘Forward’ or ‘Deferred’ based on your app’s requirements.

  5. Review your app code for any errors or compatibility issues. Make sure that all AR-related scripts are correctly implemented and that they are compatible with the AR Foundation.

Solutions to the Black Screen Issue
