Working with the tutorial, I built the house, added the textures, saved it, now I added a 'light' in the middle of the floor. Rebuilt it - File > Build WMB

Then I Previewed the Level - I am still getting the full lightning however, I do see the pool of brighter light on the floor. Is the engine suppose to automatically adjust the lighting (go darker) when you add a light (except for the spot of light) or is there some adjustment in settings I have to make somewhere?

Thank you!
