Real-time mesh deformation along splines

I am currently exploring working with splines and spline-meshes in Unreal Engine 4. They enable a level designer to sketch out advanced level designs in real-time, in the editor without ever touching 3D software. I was able to create this small scene in about half an hour. I will continue exploring this exciting area of game design.

In theory this method could be expanded to create entire cities with blueprints.
