Weird line glitch with lighting when camera rotates

Questions & Answers
1

I’ve searched for hours for a solution to this problem to no avail. Basically, there are these weird lines that show up whenever my camera rotates (first person setup). I have four lights in the scene which are all point lights. It does not seem that the type of light matters, this problem still occurs. They are all set to have no shadows and are Baked. I have set the skybox texture to None because I don’t want the light in my game. The models are imported from Blender, but the materials are from Unity.
Video below.

Any help would be greatly appreciated.

Update: I got the lines to disappear by replacing the point lights with spot lights and replacing the floor cylinder (made in Blender) with a Unity cylinder. I still don’t know the root cause of the problem, and I have much more work to do with this game, so any guidance would still be appreciated.

Okay. This is probably due to unity trying to render two things at once. You might have another object which is basically a clone of the floor and is inside the original floor. Okay, that didn’t really make sense, but what I’m trying to say, is that you might have two of the exact same objects, in the exact same place.

I FIXED IT! For others who may have the same issue, I had some duplicated faces in the mesh from blender that were trying to render in the same place. I fixed it by following this guide (after much effort to find it) mesh - Two faces inside of each other sharing same 4 vertices, why and how to fix? - Blender Stack Exchange

Thanks to @dcmrobin for the lead on how to solve this issue, because at first I had no clue what was going on.
