Hi, I’m developing a project in UE 4.27,
but I got some lighting problems when I tried to package the project and install it on Hololens 2.
No matter I put a directional light or a point light or a rect light in the scene, everything is going well when I run the project in editor with PC.
But after I package the project and install it on Hololens 2, only directional light will appear in the scene, if I put the other lights without a directional light, I can’t see anything in the scene.
Does anyone knows what is going on?
Is Hololens 2 only support directional light or did I miss something?

I have the same problem. I am grateful for any help!
