Description

Tier 3 configuration, read once when the terrain is created. Changing it on a live terrain takes effect on the next CreateTerrain.

Properties

Name	Type	Default	Meaning
`ResidencyRadius_m`BlueprintReadOnly	`double`	`2000.0`	Full-resolution residency radius around each streaming source and invoker, metres.
`bUseWorldPartitionSources`BlueprintReadOnly	`bool`	`true`	Use World Partition streaming sources; without World Partition the player cameras are the sources.
`MaxConcurrentLoads`BlueprintReadOnly	`int32`	`8`	Base-tile loads in flight on the task system at once.
`MaxBakeRequestTiles`BlueprintReadOnly	`int32`	`200`	Base tiles beyond ResidencyRadius_m the terrain may load at once so ground near a plate or corridor can bake. That ground needs everything within about 720 m resident; the terrain asks for what is missing and lets it go once baked. One window is up to 49 tiles at a 1 m cell, and a tile holds about 33 KB of heights plus its paint and ground class, so the default is about 6.6 MB and 3 km². A single window larger than this still gets its turn alone. 0 asks for none: such ground then bakes only once a source comes near, and GetBakeWait answers OverBudget.
`CollisionProfile`BlueprintReadOnly	`FCollisionProfileName`	`FCollisionProfileName(UCollisionProfile::BlockAll_ProfileName)`	Collision of every chunk. BlockAll keeps host traces (rail's floor) hitting the terrain.
`ClassPhysicalMaterials`BlueprintReadOnly	`TArray<TObjectPtr<UPhysicalMaterial>>`	—	Physical material per ground class, indexed by class (0 up to kGroundClasses - 1). An empty list, a missing index or a null entry means the engine's default physical material. Read when a chunk's collision is created; a hole cell (kTerrainHoleClass) has no material.
`bGenerateNavigation`BlueprintReadOnly	`bool`	`true`	Export chunks to the navigation system.
`SculptRefreshHz`BlueprintReadOnly	`float`	`4.f`	Collision swaps and proxy re-creates per second while a sculpt stroke is live.
`SculptLimits`BlueprintReadOnly	`FOrreryTerrainSculptLimits`	—	What the authority accepts from a player's brush: radius, strength, the keep-out margin around tunnel bores and viaducts, and what may be painted. The margin shapes the posts a brush writes, so the server and every client must run the same limits.
`SculptUndoStrokes`BlueprintReadOnly	`int32`	`32`	Strokes the sculpt undo ring keeps; an older stroke becomes permanent. A client world keeps none: its undo arrives as state.
`SculptUndoMegabytes`BlueprintReadOnly	`int32`	`0`	Memory the sculpt undo and redo images may keep alive, MiB, height codes and painted channels together; whichever limit is reached first. 0 = no byte limit (the default since the images hold compact codes).
`bSculptPaging`BlueprintReadOnly	`bool`	`true`	Page sculpt codes to the session page file (Saved/OrreryTerrain/Pages) and let the memory governor keep only nearby codes in RAM when the machine is short. Memory decides when a code is in RAM, never what the ground is. Off keeps every code in RAM. Console variables: `OrreryTerrain.Sculpt.Paging` (0 turns it off for every terrain), `.GovernSeconds`, `.MemoryAvailableMB` and `.MemoryTotalMB` (replace the machine's numbers), `.PageFileMaxMB` (a cap; beyond it the file answers disk full).
`RenderStride`BlueprintReadOnly	`int32`	`1`	v0 fixed LOD: one vertex every RenderStride posts (1, 2 or 4).
`bRegisterGroundProvider`BlueprintReadOnly	`bool`	`true`	Register this terrain as the Orrery.Ground.V3 provider.
