Oculus Quest-VR Preview Mode Stuck on Loading-UE4.25

Development Platform & Builds

Hi Guys, I built one VR scene and it worked well (VR preview) on one computer (video card RTX 2080Ti): When I clicked “VR preview” and wear the Oculus Quest, I see the scenes.

However, when I tried to VR preview the scene on another computer (video card GTX 1080), it didn’t work: When I wore the Oculus Quest, I see the Unreal window, but it was loading, and that loading lasted for over 5 minutes, and I didn’t think it would go through.

Could you give me some advice about the possible bugs and possible ways to debug? Is there something to do with how I build the scene? But the scene is actually not that complex (in total 6 GB)

I really appreciate your thoughts.

So I saw “Unreal Engine loading” grey interface with UE symbol floating in the air, but it never get loaded.
