Hey, I want to create the effect of clouds being lit from underneath by ambient city lights, however the light source options seem fairly limited. So far I've tried a light source, but placing the light where I want the light to emit from makes it look like I've just set off a nuclear bomb. I've also tried to using the surface shader on the whole planet and turned luminosity on, which didn't work either. Is it possible to import and obj like a plane, and turn it in to a light?
