Making maps is really difficult as they contain a lot of art. Blender modifiers save so much time and with the automation they improve the general quality of the mesh in general. Often on these models I defined a single window and it repeated itself all over the building. I have about another building to create and then I will start working on putting all these buildings into a standalone map. Once I have the map made I will start working on Godot again. Once the map is made I will make a video of me driving around my custom cars around the Soviet town.
