Room is dark on Oculus Go

I’m sideloading my game on Oculus Go. I package first the .apk and install it to my GO using the .bat file that is created, no error messages.

But when I start the game, the room is completely dark, I only see the 2 fire pots in each corner (only the fire) and the light of the candles, nothing else. I don’t know if the other assets are there or it’s an issue with lighting.

Anything I can check ?

I’m using assets mainly from Rome Fantasy pack on UE4 marketplace. This one I could load the demo map and it renders ok on the Go.

Maybe my lighting is not set right ?
