Why I see red flares and noisy white surfaces with Oculus VR?

Hello,
I work on an archviz on the vr Unreal template with Oculus set. I’d been creating whole model properly until I changed some settings on lights. In the editor everything is OK but when I turn the button Play with Vr mode on the computer screen I can notice some noise on white surfaces and when I put the Oculus on my head I see red flares (I wonder if it’s connected with uv lightmap or not). I’ve set the settng on defualt but the problem still apperas. Could you help me with this annoying problem?
