Sorry if this topic has been answered before, I can't seem to find anything using the forum's search. I create a simple hollow box in WED and when I build a map, I get 2 walls that are brightly lit even though I haven't added any lights. When I uncheck "create meshes" and rebuild the map, everything turns up fine. My understanding is that for A7, it's best to leave the "create meshes" option checked ... can someone tell me why this is happening?
