This video will describe the required steps to get Road Architect from github properly installed in a fresh Unity project. It's quick and painless one you know what to do. Road Architect is a very powerful procedural road creation tool for Unity, it's one of the best, and it's free! Try it today, I don't think you'll regret it. I'll share my personal workflow for getting started with a new road project, creating a terrain and laying down my first piece of a road system.
