A runtime module: in the editor and in packaged games. 3 public headers.

Build.cs: PublicDependencyModuleNames.Add("OrbdaleTerrainPCG");
Type: Runtime

OrbdaleTerrainPCGData.h

The terrain as a UPCGSurfaceData that samples the ground through one SampleGround call per batch, with height, slope, ground class, holes, precision and one attribute per paint layer.

#include "OrbdaleTerrainPCGData.h"

EOrbdaleTerrainPCGSurface enum
Which ground a terrain surface data reads.
EOrbdaleTerrainPCGAccuracy enum
How exact a sample must be.
FOrbdaleTerrainPCGAttributes struct
Which attributes the points carry (the Z, rotation and density are always written).
FOrbdaleTerrainPCGParams struct
How a terrain surface data samples.
UOrbdaleTerrainPCGData class
The terrain as PCG surface data (Tier 3).

OrbdaleTerrainPCGRefresh.h

Experimental

The opt-in re-run on edit: UOrbdaleTerrainPCGRefreshComponent on the actor that owns the PCG components, and UOrbdaleTerrainPCGSubsystem, which reads the ground journal and re-runs the components an edit reached.

#include "OrbdaleTerrainPCGRefresh.h"

EOrbdaleTerrainPCGRefreshMode enum
When a PCG component re-runs over ground that changed.
EOrbdaleTerrainPCGRefreshKind enum
How the subsystem re-ran one PCG component.
UOrbdaleTerrainPCGRefreshComponent class
Opt-in: re-run the PCG components on this actor when the ground under them changes (Tier 3).
UOrbdaleTerrainPCGSubsystem class
The listener behind UOrbdaleTerrainPCGRefreshComponent: one per world, game thread.

OrbdaleTerrainPCGSettings.h

Experimental

The PCG node Get Orbdale Terrain Data: outputs the world's terrain as one surface data over the component's bounds.

#include "OrbdaleTerrainPCGSettings.h"

UPCGGetOrbdaleTerrainDataSettings class
Get Orbdale Terrain Data: outputs the world's terrain as one surface data over the component's bounds.
FPCGGetOrbdaleTerrainDataElement class
Runs on the game thread; not cached, because the data's own CRC carries the edit revision.
