Fabrice, I built my track using a topdown image of a race track. I then used a bitmapmaterial using that bitmapdata and applied it to a plane.
I want to do what you suggested with the paths. Is there an easy way for me to work out the path coordinates around this track? I could drive around the track with my camera and trace out the coordinates but there is probably an easier way right?
