APIs below are verified against the 5.8 headers; older forms are listed under \"Deprecated — do not use\".\r\n\r\nThis skill covers how a `UWorld` is composed and swapped at runtime: World Partition grids, data layers, HLOD, level instances, classic sub-level streaming, streaming volumes, and map travel. Everything here lives in the `Engine` module (`Engine/Source/Runtime/Engine`), so `Core`, `CoreUObject` and `Engine` in `PublicDependencyModuleNames` is all that is needed. The one exception is the Level Streaming Persistence plugin, which adds the `LevelStreamingPersistence` module.\r\n\r\nFor end-to-end configurations per game type (open world, hub-and-spoke, procedural, chapter-based, volume-driven, dedicated server), see [streaming patterns](references/streaming-patterns.md).\r\n\r\n## Context\r\n\r\nRead `.agents/ue-project-context.md` if it exists (module names, conventions, enabled plugins, GAS/networking setup). Do not stop if it is missing.\r\n\r\nIdentify the area from the request and the codebase. Ask only when two plausible readings would produce different code.\r\n\r\n| Request is about… | Go to |\r\n|---|---|\r\n| Picking between World Partition and sub-levels | [Choosing a Streaming Model](#choosing-a-streaming-model) |\r\n| Grid streaming, streaming sources, blocking loads, CVars | [World Partition Runtime](#world-partition-runtime) |\r\n| Turning content on and off inside a partitioned world | [Data Layers](#data-layers) |\r\n| Reusable level chunks placed in the editor, packed actors | [Level Instances](#level-instances) |\r\n| `LoadStreamLevel`, `ULevelStreaming`, volumes, runtime instancing | [Sub-Level Streaming](#sub-level-streaming) |\r\n| `OpenLevel`, `ServerTravel`, `ClientTravel`, seamless travel | [Level Travel](#level-travel) |\r\n| Distant proxies for streamed-out cells | [HLOD](#hlod) |\r\n| Keeping actor changes across a streaming cycle | [Level Streaming Persistence](#level-streaming-persistence) |\r\n| Per-world managers, state that must survive travel | [World Subsystems and Cross-Level State](#world-subsystems-and-cross-level-state) |\r\n\r\n## Choosing a Streaming Model\r\n\r\n| Situation | Use | Why |\r\n|---|---|---|\r\n| One large continuous map | World Partition grid | Automatic spatial cells, no manual sub-level bookkeeping |\r\n| Optional content inside a partitioned map | Data layers | `EDataLayerRuntimeState` toggles without travel |\r\n| The same level asset placed many times in the editor | `ALevelInstance` / `APackedLevelActor` | Edited as a unit, packed into instanced meshes |\r\n| The same level package spawned many times at runtime | `ULevelStreamingDynamic::LoadLevelInstance` | Creates a uniquely named package per instance |\r\n| Discrete hand-authored zones in a non-partitioned map | `ULevelStreaming` sub-levels | Explicit load and visibility control per zone |\r\n| Proximity-driven interiors in a non-partitioned map | `ALevelStreamingVolume` | Camera-position driven, no gameplay code |\r\n| A different map entirely | `OpenLevel` / `ServerTravel` | Tears down and rebuilds the world |\r\n\r\nWorld Partition and sub-level streaming are mutually exclusive on the same persistent level. `UWorld::IsPartitionedWorld()` (`Engine/World.h:2968`) reports which one is in play; `AWorldSettings::GetWorldPartition()` (`GameFramework/WorldSettings.h:837`) returns the partition object (the `WorldPartition` member is protected).\r\n\r\n## World Partition Runtime\r\n\r\n`UWorldPartition` (`WorldPartition/WorldPartition.h`) owns the runtime hash that turns actors into cells. `UWorldPartitionSubsystem` is the per-world entry point and is a `UTickableWorldSubsystem`.\r\n\r\n```cpp\r\n#include \"WorldPartition/WorldPartition.h\"\r\n#include \"WorldPartition/WorldPartitionSubsystem.h\"\r\n\r\nUWorldPartitionSubsystem* Subsystem = GetWorld()->GetSubsystem<UWorldPartitionSubsystem>();\r\nif (Subsystem && Subsystem->IsAllStreamingCompleted())\r\n{\r\n    // Every cell has finished loading, adding to or removing from the world.\r\n}\r\n\r\nSubsystem->ForEachWorldPartition([](UWorldPartition* Partition)\r\n{\r\n    return Partition->IsStreamingEnabled(); // return false to stop iterating\r\n});\r\n```\r\n\r\n`UWorldPartitionRuntimeCell` is the unit the hash produces. Query readiness at an arbitrary point with a query source instead of polling actors:\r\n\r\n```cpp\r\n#include \"WorldPartition/WorldPartitionRuntimeCell.h\"\r\n#include \"WorldPartition/WorldPartitionStreamingSource.h\"\r\n\r\nTArray<FWorldPartitionStreamingQuerySource> QuerySources;\r\nQuerySources.Emplace(TargetLocation); // FVector\r\n\r\nconst bool bReady = Subsystem->IsStreamingCompleted(\r\n    EWorldPartitionRuntimeCellState::Activated, QuerySources, /*bExactState=*/false);\r\n```\r\n\r\n`EWorldPartitionRuntimeCellState` is `Unloaded`, `Loaded`, `Activated` (`WorldPartitionRuntimeCell.h:202`).\r\n\r\n### Streaming sources\r\n\r\nAny object can drive streaming by implementing `IWorldPartitionStreamingSourceProvider` (a plain interface struct in `WorldPartitionStreamingSource.h`) and registering it with the subsystem. For the common \"this actor pulls cells in\" case, add a `UWorldPartitionStreamingSourceComponent` instead — it already implements the provider and registers itself.\r\n\r\nThe two virtuals to override are `virtual bool GetStreamingSources(TArray<FWorldPartitionStreamingSource>& StreamingSources) const` and `virtual const UObject* GetStreamingSourceOwner() const`. Register in `BeginPlay` with `UWorldPartitionSubsystem::RegisterStreamingSourceProvider(this)` and release in `EndPlay` with `UnregisterStreamingSourceProvider(this)`. A complete actor implementation is in [streaming patterns](references/streaming-patterns.md#custom-streaming-source-provider).\r\n\r\n- `EStreamingSourceTargetState`: `Loaded` (in memory, not added to the world) or `Activated`.\r\n- `EStreamingSourcePriority`: `Highest`, `High`, `Normal`, `Low`, `Lowest`, `Default` (equals `Normal`).\r\n- `TargetGrids` plus `EStreamingSourceTargetBehavior` (`Include` / `Exclude`) restrict a source to named runtime grids.\r\n- `bBlockOnSlowLoading` opts the source into the engine's blocking path when streaming falls behind. Leave it false for cosmetic sources.\r\n- `UWorldPartitionSubsystem::GetStreamingSources(const UWorldPartition*, TArray<FWorldPartitionStreamingSource>&)` reads back everything currently registered.\r\n\r\n### Runtime CVars\r\n\r\n| CVar | Effect |\r\n|---|---|\r\n| `wp.Runtime.EnableServerStreaming` | Server-side cell streaming on dedicated and listen servers |\r\n| `wp.Runtime.EnableServerStreamingOut` | Lets the server stream cells back out |\r\n| `wp.Runtime.BlockOnSlowStreaming` | Blocks the game thread when a blocking source falls behind |\r\n| `wp.Runtime.MaxLoadingStreamingCells` | Caps concurrent cell loads |\r\n| `wp.Runtime.OverrideRuntimeLoadingRange` | Overrides a grid's loading range for testing |\r\n| `wp.Runtime.ToggleDrawRuntimeHash2D` | Draws the cell grid on screen |\r\n| `wp.Runtime.DumpStreamingSources` | Logs every registered streaming source |\r\n| `wp.Runtime.HLOD` | Enables and disables HLOD proxies at runtime |\r\n\r\n## Data Layers\r\n\r\nActors reference data layers through `AActor::DataLayerAssets` (`TArray<TSoftObjectPtr<UDataLayerAsset>>`, `GameFramework/Actor.h:1123`). `UDataLayerAsset` is the authored asset, `UDataLayerInstance` is its per-world instance, and `UDataLayerManager` is the runtime accessor, reachable from any object inside a partitioned world.\r\n\r\n```cpp\r\n// MyDataLayerController.h\r\n#pragma once\r\n\r\n#include \"CoreMinimal.h\"\r\n#include \"GameFramework/Actor.h\"\r\n#include \"MyDataLayerController.generated.h\"\r\n\r\nclass UDataLayerAsset;\r\n\r\nUCLASS()\r\nclass MYGAME_API AMyDataLayerController : public AActor\r\n{\r\n    GENERATED_BODY()\r\n\r\npublic:\r\n    UFUNCTION(BlueprintCallable, Category = \"MyGame|Streaming\")\r\n    void SetDungeonActive(bool bActive);\r\n\r\n    UFUNCTION(BlueprintCallable, Category = \"MyGame|Streaming\")\r\n    bool IsDungeonActivated() const;\r\n\r\nprotected:\r\n    UPROPERTY(EditAnywhere, Category = \"MyGame|Streaming\")\r\n    TObjectPtr<const UDataLayerAsset> DungeonLayer;\r\n};\r\n```\r\n\r\n```cpp\r\n// MyDataLayerController.cpp\r\n#include \"MyDataLayerController.h\"\r\n#include \"WorldPartition/DataLayer/DataLayerAsset.h\"\r\n#include \"WorldPartition/DataLayer/DataLayerInstance.h\"\r\n#include \"WorldPartition/DataLayer/DataLayerManager.h\"\r\n\r\nvoid AMyDataLayerController::SetDungeonActive(bool bActive)\r\n{\r\n    UDataLayerManager* Manager = UDataLayerManager::GetDataLayerManager(this);\r\n    if (!Manager || !DungeonLayer)\r\n    {\r\n        return;\r\n    }\r\n\r\n    const EDataLayerRuntimeState NewState =\r\n        bActive ? EDataLayerRuntimeState::Activated : EDataLayerRuntimeState::Unloaded;\r\n\r\n    Manager->SetDataLayerRuntimeState(DungeonLayer, NewState, /*bInIsRecursive=*/true);\r\n}\r\n\r\nbool AMyDataLayerController::IsDungeonActivated() const\r\n{\r\n    UDataLayerManager* Manager = UDataLayerManager::GetDataLayerManager(this);\r\n    if (!Manager || !DungeonLayer)\r\n    {\r\n        return false;\r\n    }\r\n\r\n    const UDataLayerInstance* Instance = Manager->GetDataLayerInstanceFromAsset(DungeonLayer);\r\n    return Instance && Manager->GetDataLayerInstanceRuntimeState(Instance) == EDataLayerRuntimeState::Activated;\r\n}\r\n```\r\n\r\n`EDataLayerRuntimeState` (`DataLayerInstance.h:23`): `Unloaded`, `Loaded` (in memory but not visible — use it to pre-warm), `Activated` (loaded and visible).\r\n\r\nOther manager entry points: `SetDataLayerInstanceRuntimeState(const UDataLayerInstance*, EDataLayerRuntimeState, bool bInIsRecursive)`, `GetDataLayerInstanceEffectiveRuntimeState`, `GetDataLayerInstances()`, `GetDataLayerInstanceFromName(const FName&)`, and the `BlueprintAssignable` delegate `OnDataLayerInstanceRuntimeStateChanged`. To sweep every instance:\r\n\r\n```cpp\r\nManager->ForEachDataLayerInstance([](UDataLayerInstance* Instance)\r\n{\r\n    return Instance->IsRuntime(); // return false to stop early\r\n});\r\n```\r\n\r\n**Authority:** a runtime data layer with no load filter only responds to state changes made on the server, and the resulting state replicates. Client-only layers must be changed on the client, server-only layers on the server. The old world-subsystem accessor still exists as a deprecated shim — see [Deprecated — do not use](#deprecated--do-not-use); route everything through `UDataLayerManager`.\r\n\r\n## Level Instances\r\n\r\n`ALevelInstance` (`LevelInstance/LevelInstanceActor.h`) places a `.umap` as a reusable chunk and implements `ILevelInstanceInterface`. `ULevelInstanceSubsystem` is the `UWorldSubsystem` that tracks them.\r\n\r\n```cpp\r\n#include \"Engine/World.h\"\r\n#include \"LevelInstance/LevelInstanceActor.h\"\r\n#include \"LevelInstance/LevelInstanceSubsystem.h\"\r\n\r\nvoid AMyLevelInstanceDriver::ShowRoom(ALevelInstance* RoomInstance)\r\n{\r\n    if (!RoomInstance)\r\n    {\r\n        return;\r\n    }\r\n\r\n    RoomInstance->LoadLevelInstance(); // queued; loads on the subsystem's next streaming update, so IsLoaded() is false this frame\r\n\r\n    ULevelInstanceSubsystem* Subsystem = GetWorld()->GetSubsystem<ULevelInstanceSubsystem>();\r\n    if (Subsystem && Subsystem->IsLoaded(RoomInstance))\r\n    {\r\n        Subsystem->ForEachActorInLevelInstance(RoomInstance, [](AActor* LevelActor)\r\n        {\r\n            LevelActor->SetActorTickEnabled(true);\r\n            return true;\r\n        });\r\n    }\r\n}\r\n```\r\n\r\n- `ILevelInstanceInterface` runtime ","tagline":"Use when streaming levels in and out, setting up World Partition, or moving between maps.
