UE4 Static mesh Glow problem

rgvsharma98

Hello Everyone!

I'm working on a level design and I imported this warehouse that I created in maya, and everything inside the warehouse mesh has a weird white glow around it, and black in some cases! Nothing outside these building looks this way but I don't have any place in map where character can go inside. I've baked light but nothing changed. Pls HELP TvT

Thank you!!
