Data Structures

FCWorldMakerStruct

Configuration structure for world generation parameters.

Name	Description
cellSize	Size of a single terrain tile in world units (default 20000.0)
nbTileAround	Number of tiles to generate around the tracked pawn
nbMinPointPerSide	Minimum number of vertices per tile side at LOD 1
maxLODFactor	Maximum LOD multiplier for closest tiles
doNotTrackPawn	If true, generates tiles once at origin and stops tracking
removeFurthestTiles	If true, removes tiles that fall outside the generation radius
curvaturLODReduction	LOD reduction factor based on distance (0.0 disables LOD variation)
calculateNormal	Whether to compute normals on generated meshes
poolSizeStart	Number of tiles per pool batch on first generation pass
poolSizeRun	Number of tiles per pool batch on subsequent passes
collisionOnClosePMCOnly	If true, only the closest tiles (max LOD) have collision enabled
easeMethod	Easing function used for noise blending between zones (default QuinticInOut)
shadowBehavior	Shadow definition for the generated terrain
noiseMeshMaterial	Material applied to generated terrain meshes
worldMakerClass	Subclass of `UCAbstractWorldmaker` to instantiate (ProceduralMesh or DynamicMesh)
waterActorClass	Actor class spawned as water plane, follows the pawn at the lowest Z
fogActorClass	Actor class spawned as fog volume

// FCWorldMakerStruct is typically configured in a DataTable row
// and referenced by ACWorldSpawner via a FDataTableRowHandle.

FCWorldSpawnerDataStruct

DataTable row structure combining world maker configuration with a noise asset.

Name	Description
worldMakerStruct	The `FCWorldMakerStruct` configuration for this world
worldNoiseDataAsset	`UCNoiseDataAsset` defining the noise layers for terrain generation

// FCWorldSpawnerDataStruct is a FTableRowBase, designed to be used in a DataTable.
// ACWorldSpawner references a row via FDataTableRowHandle (worldMakerRH).

// If no data is found at runtime, a default flattened world is used.
// If no worldNoiseDataAsset is set, a default flat noise is used.
