Landscape is sorted now (note this is from Max so not rendered in game) luckily this was totally worth doing
The white outline isn't the road yet.. I overlayed the trackmap I made before... in game, over the terrain mask and used a width section of road to smooth out a path, smoothing elevations between the road edge and mountains...
As the road bed is now much much smoother, when I select the points on the mesh for the road splines... They will have a much better flow
Be my guest if you'd like to count how many corners there are... I have no idea still
