This city was built in minutes entirely inside Unreal 5 using Geometry script Blueprints (Dynamic Meshes). All blueprints used to create this city are 100% procedural.
The tools are incredibly easy to use. It's simply drag, drop and adjust parameters. See video.
Geometry Script is a built in plugin inside Unreal Engine 5.
These blueprints will be made available on the FAB market place if there is enough interest.
Enjoy!
