Functions
static const TArray< FString > &	UCarlaStatics_GetMapFiles ()
static TArray< FAssetData >	UCarlaStatics_GetRegistryWorlds ()
	UWorld assets the asset registry knows outside /Engine (project content, mounted plugins, content packs).
static bool	UCarlaStatics_IsHiddenMap (const FString &PathOrPackage)
	Maps that get_available_maps must not list: the OpenDRIVE-generated scratch map, sub-levels and World Partition helper packages, and the test maps — except EmptyMap, which is a supported empty sandbox (it ships with an empty OpenDRIVE file so get_map() works).

Variables
static bool	UCarlaStatics_bMapFilesDirty = true
static TArray< FString >	UCarlaStatics_CachedMapFiles
	The recursive .umap walk over the project and plugin content dirs is expensive (tens of thousands of files in an editor tree) and runs on the game thread for get_available_maps / load_world, so its result is cached keyed on the set of content dirs; content pack mount/unmount invalidates it.

UCarlaStatics_GetRegistryWorlds()

static TArray< FAssetData > UCarlaStatics_GetRegistryWorlds ( )

static

UWorld assets the asset registry knows outside /Engine (project content, mounted plugins, content packs).

Cooked base maps live inside Pak/IoStore containers where the .umap walk finds nothing; the premade AssetRegistry.bin of a packaged build still lists them. The registry asserts on non-game threads, so off-thread callers get an empty list.
