No, this scene is not published anywhere, was made specifically for video capture, and contains a lot of cached things to minimize possible response delays from tile providers and services.

The buildings were implemented using the Buildings component.
The problem with slow buildings is probably because you are using too small a minimum zoom.
In cities when the zoom is small it can put a very large load on the OSM Overpass server and in some cases the response can be tens or hundreds of megabytes in size.
As an alternative you can use MapboxBuildingManager.
It works much faster.

The fog settings I showed in this video:

I am specifically interested in the way the buildings were implemented, and the fog. I found the building example scene but the assets are created in real time which can be slow.
