How to import cities into UR4?

I was wonder if there is an easier way to make a city without having to build each building. Also without having to pay for prebuilt buildings. The city I’m making is about as big as Skyrim, So I’ll need a faster way to make my city.

You need a procedural approach:

On the other hand, you say import indicating you’ve already made it and just need to bring it into the engine. So which one is it?
