The blockout geometry in Unreal Engine

Creating the Building Structures

The building structure is generally just a set of cubes that are extruded.

As you can see on the screenshot below the geometry has a lot of edge loops that may seem unnecessary at first, but they’re actually used later on in the engine for vertex painting.

The unwrapping process was fairly simple as well, and since we’re gonna be using a lot of decals, trim sheets and other objects on top of this structure, there won’t be any seams problem.
