Oculus weird lens flare


I have some trouble with extreme lens flare in one project. While in normal mode everything is looking great, starting the game in VR preview results in blinding light (mostly on the right eye) and very weird reflections of the floor - like a piece of the floor is right in front of my camera all the time (screenshot).

I’ve checked it in other projects and it’s working just fine. Setting Lens Flares in Global PostProcess to 0 helps a bit, but not enough. Finally, I’ve deleted eveything like Skylight, Directional Light, BP_Sky etc. and left the Character Blueprint with Camera and collider only and build the lighting after that - didn’t help.

I guess the problem is in the floor, but I have no idea how to fix it. The floor has no emissive material.
