Context :

A side project on my free time, still working on it.
It's a propotype for a procedural generated racegame.
I work on the track generation, with an algorythm genearting a circular way with random turns.

To generate the meshs and Uvs maps of the road I use the "It's A Road Tool" by Parabox, LLC on the asset store :

Car controller come from the Unity's Standards Assets.
