EWallKind

Why a formation edge holds a vertical step: a retaining wall the terrain reports.

Declaration

enum class EWallKind : uint8_t

Header: #include "Native/EarthworksResult.h"
Module: PublicDependencyModuleNames.Add("OrreryTerrainCore"); in your module’s Build.cs.
Stability: Stable: changes within a major version only add.

The terrain only reports walls; the owner of the formation draws them (rail: a retaining-wall kit, as it draws portals).

Value	Meaning
`Shoulder` = 0	Another feature's formation lies across a gap too narrow for the steepest slope: the ground falls from the upper shoulder at the steepest slope, and the rest is a step at the lower one.
`Daylight`	The batter found no daylight within MaxDaylight, even steepened to the steepest slope (a mountainside rising faster than it, or a valley side falling faster): the batter stops at the formation edge and the step to the natural ground there is a wall.
`PortalFold`	A tunnel approach cutting folded to its portal's width (openings, a later piece).
