How to Create a City, Covered with Fog in Blender?

For all of you, Silent Hill fans, here is the tutorial about creating the City in Blender.

Discover how to create a city from scratch and enhance it with volumetric fog and lighting.

The process of city building can be a pain in the ass, but using the shortcuts like going into draft mode and texturing everything in one go cut the production time down tremendously.

In this video, we’re doing exactly that: using various tricks to make Silent Hill-ish scene.

A brief overview of the city generation stages:

1. Go to and Export the .OSM file

To be able to import this file into Blender, we need to download and activate the addon.

After importing .OSM file to Blender, we should have the outlines of the buildings.


2. Import .OSM file to Blender and Extrude the Buildings
