First of all, sorry - my english is what it is, because I’m still learning.
Why my lighting in my map is so weird? Before building lighting textures looks fine and walls cast shadows. But when I press “Build Lighting Only” everything is weird and not working. Texture on one of the object is totally broken, shadows on the walls are completely black and there is not casted shadows on the floor. You can see what I mean on the screenshots. What’s going on here?
