I’ll be honest: we are actually quite proud of this workflow. We developed it for our “Lustica Bay” Project, where a complete new village was built on a hillside.
Anyhow, this workflow will help you to create a new hybrid mesh, that combines a loop based road mesh with a “chaotic” triangle mesh for the terrain – sounds weird, but in fact not so stupid after all :).
Check it out – it’s in two parts:
Part 1: Creating the base mesh
Part 2: Texturing the mesh, Refining, Detailing and animating vehicles
and last but not least … if you want to learn a completely different approach – from 2011 but still totally valid :): Conforming a Road onto a Terrain
