Over the past few months I've created a procedural framework in Houdini in my spare time, with which you can relatively easy create tracks from scratch. It is procedural, which means it could load whatever Openstreetmap data and generate Amsterdam, New York or London.Since it's a procedural, it's non-destructive, meaning that everything remains live so the developer can keep iterating without destroying previous steps.A proof of concept is this track called Wijchen, a track situated in this small town in the Netherlands. I want to emphasize that most of it is programmer art; my focus was on the framework, not on high-quality assets.
