Stadium Builder - Procedurally generated from an input curve and a point wrangle driven profile.
Here’s the stadium builder functioning within Unity as a Houdini Digital Asset. Rendered using the latest verified HDRP in Unity 2020.1.
Procedural Road Generator - Given an input terrain / heightfield, generate a network of roads entirely procedurally that conform to the terrain and avoid slopes. Minor height adjustment matches the terrain to the resulting roads.
