Did you "render all lightprobes" ?
Also the "quality" of light seems to depend on the atmosphere being used. Some won't show any lightsources at all except for the default atmosphere light.
Publishing something with the "ATM_Default" atmosphere is generally a bad idea in my expeience.

GM Mode supports both see through, fading and non-fading walls and roofs.
I suggest using "see hrough" for all walls, and fading for roofs and/or upper floors.
You could experiment with opacity to contain the illusion of tall buildings.

It's tricky to get right , but works rather well once you do.
