Kenny Lammers walks through the fundamentals of using Houdini to create procedural systems to rapidly generate Large Scale Environments in Houdini and Houdini Engine.
This gives you a more hands-on look at how to construct a pipeline for Large Scale Environments in Unity. By the end we will have built up a procedural tiled terrain system, complete with erosion, a smart foliage scattering system, and implemented a basic road to demonstrate how all these elements interact with each other.
