Exporting stock buildings to add lights

Hi, Is there a way to export the scenery object in the sdk so I can mod the buildings with night lights. I use gen_hangar buildings for my airport creation and only can use the sdk warm,cold light to light the buildings. I have some understanding of creating lighting effects in blender. I wish not to create something new as it may takes time and just try to disassemble the windows of the generic hangar and give it lights. Anyone can give a light on this? thanks!
