Check out a crazy city material in Substance Designer created by Jan Trubač. 

It all started will his friend challenging the artist to make an entire city in Substance Designer.

The artist noted that this way appeared to be quite convenient. Looks like it features a number of parameters that allow setting up all sorts of layouts procedurally in no time.

"This is by far my biggest Substance project so far. The process of creating such a complex material was absolutely crazy."

Once again, it's 100% Substance Designer. The final shots were rendered with Corona Renderer. You can learn more here.
