Hello there. I am having an issue with building the lighting of my scene.
Everything in this scene is a static mesh besides the doorframe. Yes that’s right, the floor including the lower middle and the ceiling with the upper middle are both static meshes. The surrounding walls are one static mesh too. Same with the doors. Every time I build the lighting it gets stuck on 96%. One time I left it in the morning to build and came back from school to find the editor frozen. In the lower middle of the floor there is also this problem with the reflection. There is a triangular shaped area on the floor that displays reflections incorrectly.
The screenshot of the problem is here
Can someone help me out please?
