Allright done, is in SR repo.
I did many things. Scaled down a bit, is 24 km now, not a big difference. Doesn't feel too streched, still there are few fast straights.
Changed road materials, to more natural, added 2nd asphalt.
Decorated terrain, looks nice. And used it in few places as road support, no columns otherwise.
Also made some simple obstacles with terrain. Added some small terrain jumps (in straight parts). And few water/mud ponds.
Checkpoints, yeah have to do them myself always.
Great stunt track. Definitely wins for having 4 loops in same place.
