In the VR game mode my left eye is normal as the editior. However for my right eye the fog is so intense for some reason that the scene is so white. In close distance, both eyes are fine:
Throughout some testing, I found that my problem occurs while using Meta Quest Link with UE5.3 VR preview. Turning off Mobile Multi-View solves the Link streaming problem, but it does not impact the packaged app in any way. Hope it will help someone who encounted the same problem:)
