Title says it all. Where can I find the shader with the city skyline seen in the banner below? Is the shader part of the built-in ones, did someone from the community make it, or was the skyline just edited into the picture?

I think it's just art.. (Edited in)

I think a generic shader like sunlight or something was used then the skyline edited in

I am 100% sure it's the shader called "heaven finally" but edited.
