Combined all from the two previous uploads and the foder names are correct. It has to be right this time.
Sorry for the mess!

If you did not get it to work managing the mess by yourself, I cleaned it up and added the possibility of spawning 60 cars in Track day for traffic. Beware - when the VRAM of your graphics card gets overfilled, the framerate drops a lot. For 6 GB that means ~48 cars of decent quality (CSP 0.1.51 and Sol 1.5.1 with 2d clouds, dynamic weather).
