Road elevation is now sampled at the point on the road segment nearest the column being carved, instead of at the segment's midpoint. The old behaviour gave every column near a segment that segment's single midpoint height, so each stretch of road was one flat plank and consecutive planks stepped like a staircase wherever the road crossed a gradient. Elevation now varies continuously along the segment, and because neighbouring segments share an end point the height matches exactly at the joins. A new ROAD_GRADE_SMOOTHING constant dials between holding a straight grade (cut-and-fill) and hugging the land, per D-021. Untouched: density field, Marching Cubes, chunk dimensions, the .dat contract, and the 2D A* road network itself. Only how existing paths are carved into 3D.

// --- ROAD GRADE TUNING ---------------------------------------------
|

// How much a road "holds a grade" instead of following every bump in
|

// the ground underneath it. Roads exist to be DRIVEN on, so this is a
|
|
// driveability setting, not a cosmetic one.
|
|
//
|
|
// 0.0 = hugs the land: the roadbed follows the terrain exactly.
|
|
// Never steps, but inherits every lump the ground has.
|
|
// 1.0 = holds a grade (default): each stretch of road is a straight
|
|
// ramp between its two path points, cutting through small
|
|
// bumps and filling small dips. Smoothest to drive.
|
|
//
|
|
// Values in between mix the two. Raise toward 1.0 for a more
|
|
// engineered road, lower toward 0.0 for a more rustic one.
|
|
//
|
|
// NOTE: this affects road ELEVATION (terrain shape under the road),
|
|
// not colour. Tune it properly once vehicles exist to drive on it.
