Awesome. Another pretty track. Will be as Sur2 in 2.5. I'll try to balance the jumps a bit better since it seems problematic to land well on other side on half of them.
Done. Is on master. Fixed all jumps, less speed needed. For pipe jump opened on-pipe below (half-on-pipe ) to not go onto road below, and made it broader to land easier, still a bit tricky.
Added height fog with light, more road/pipe materials, 1 more grass, made crystals vegetation a bit bigger, added 2 black pyramids.
