One of my personal project that I have finally been able to finish!
Used Google maps, and my trip to Italy as a reference, started the project in UE4.26 and completed in UE 5.0 to make use of Lumen and have Realtime dynamic lighting in the scene.
Created most of the assets and textures in the scene including the Cathedral, used Quixel for some of the Textures and generic assets along with borrowing some assets from free unreal projects.
