Okay is in SR repo.
Changed terrain blendmap. Generally a bit darker. Road materials, more gravel, other for pipes.
On pipes are now wider, rather easy. Made more room, so concrete bariers are easier, high top.
Changed building to the new 0AD ancient chinese buildings, ugh I'm still dealing with 2nd half of them.
Lastly checkpoints, and some FPS improvements.
It's a very cool interesting track.
