GhostTown is an amazing tool for city generation with plenty of control but it’s only available for 3DS Max.
CityGine is still in development and we likely won’t see a release until later this year.
RoadBuilder has some potential but isn’t a complete package.
ESRI City Engine is a phenomenal tool but I can’t find any modern support for Unity integration.
Are there any procedural city tools currently available for Unity that offers spline-based control over roads?
