I'm using the Quest connected to my development machine using Oculus Link. I can do VR Preview without any issues. If your Quest is connected and detected by the Oculus software running on your computer, then opening a UE4 project should enable the VR Preview button (if everything else in the project is setup properly for VR).
Okay. Got that resolved. How do you handle the Unreal Preview when using the ES3.1 Shader Model - which is for the Android System and needed for Oculus Quest?
Since it's not supporting the Shader Model 5 - that is by default used within Unreal.
Lights do have different values - as far as I can tell... only the Direct Light is supported. Shaders look of course different.
How do you work on a look development, if lights are not supported for ES3.1?
