Weird black field

There's an odd black field blocking my vision. There's only 2 textures on the map, nothing else, the wall and the floor.

Would appreciate any help.

Set the BoxLight's height to at least 4, if you set it any higher, that is. If that doesn't work, try shrinking it with different combinations. Don't make it extremely big.

I think it's around 300 BoxLight size, do you start getting strange black artifacts.

Try reducing the box light size. It's the only thing that could cause that, for what I know.

Oh lol. I usually put big boxlights in order to see in game while testing but I put a zero to much in this one (x value 1000)

That's the clip plane. You need to increase the range, or simply keep the room sizes and their box lights within the clip plane range, before it goes away
