Developer Notes

AREnvProbe had Desktop Renderer and Metal v.2.1 enabled

See https://issues.unrealengine.com/issue/UE-81660 for fix

Description

If Metal Desktop Renderer and Metal v2.1 are both active, the AR passthrough camera renders as black.

 

Issue not observed if only 'Metal Desktop Renderer' or 'Metal 2.1' is selected

Issue not observed in 4.23.1

 

4.25 MAIN (11104400) verification blocked by unresponsive editor on 'launch on' [Link Removed]

Steps to Reproduce
  1. Create AR Template project
  2. Enter Remote Build info
  3. Enable 'Metal Desktop Renderer' and switch "Max. Metal Shader Standard To Target" to 'Metal v2.1' (restart editor)
  4. Launch on Device. (Confirmed on ipad versions A1701 and A1876. User reported seeing this on iPhone X as well)

Result: View will be black (UI will still be visible) - Some visibility can be gained by placing finger over camera
