Always start the file with the track section, followed by flags/settings, of course replacing param and value for the parameter and the value. After the track table comes the segments table. Here you define the segments, from one to a maximum of 40.

Where all numbers are unsigned integers, p1 and p3 are bezier curve anchors, p2 is a bezier curve control point. pNx and pNy are unsigned 32-bit integers, and their unit is millimetres ‘shape_outer’ describes the outer outline of the track segment ‘shape_inner’ describes the inner outline of the track segment

Aditionally, you can add special properties for that segment with local_param.


name trckname

The name must be an eight character alphanumerical string that is not ’_DEFAULT’

time night/day

biome = snow/lava/lake/desert/forest/rosegarden

An additional “color - while/red/blue/yellow/green/pink” parameter will be generated from the biome.
