This is my fourth make a race track tutorial in blender. I know.. but it's got new ideas in it like: how to stop the twist when adding hills, how to make the track smoother with no polygons in the curving, plus I have integrated a matching low poly landscape setting in the background with the track.
The tutorials is broken up into chapters for easier navigation.
