[Q] Procedural City Generator with Spline-based Roads?

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?

Also Houdini is a great procedural tools for unity…

Im not sure if this is what your looking for. Its more specialized in its current form and wont be getting major updates for awhile until im done with my current demo design project. Synstasis. https://synstasis.com CiDy is unity integrated and allows you to create and edit city blocks. https://www.assetstore.unity3d.com/en/#!/content/55298
