Instanced stereo and deferred rendering are broken (again) in 5.8:

Editor/build crashes when Instanced Stereo is enabled together with deferred rendering:

  • New VR Template Project

  • Disable forward rendering

  • play in VR
    → crash

  • disable Instanced Stereo

  • play in VR
    → works again

Thanks for the report! This has been fixed in 5.8.1 which will be released in the next few weeks. I will follow up w. the reporter as they noted 5.8.1 in the title of the bug report but I can’t reproduce it there.

Great!
@VictorLerp thank you!

Still hoping for a once stable deferred VR version :grinning_face_with_smiling_eyes:

We also fixed reflection captures and shadows in the right eye, but I think they will land in 5.8.2.
