weird light when no light is enabled in scene

I have some weird lighting problems and they are pretty clear when i disable all the lights. Here’s what ti looks like:

What’s the problem?

is there any lights in your level? is theres lights outside the room they could be bleeding in. this is a real possibility when using planes as walls for instance.

No I did check everything outside and I also used boxes as walls. Anyway I changed the lighting to real-time and it seems okay now. Thanks anyway!
