Basically college entrence is flat texture, real model hides behind it. I use Obscure College, but it does not change exterior in this place. I have already checked FAQ, restarted the game, also changed uLargeRefLODGridSize=11 to 5, results are always the same. Solution is beyond my reach at this point, I will be grateful if you can figure out what is broken.
P.S
Disabling it in console fixes the issue, but I'm pretty sure it will break LOD once I go away.
