ActiveAssets	TSet< UObject * >	Assets that were added/retrieved since the last call to MarkAssetsAsSlate();.	USDAssetCache.h
bAllowPersistentStorage	bool		USDAssetCache.h	EditAnywhere Category="Assets" AdvancedDisplay
CriticalSection	FCriticalSection	Used to ensure thread safety.	USDAssetCache.h
OwnedAssets	TSet< TWeakObjectPtr< UObject > >	Points to the assets in primary storage, used to quickly check if we own an asset.	USDAssetCache.h	NonPIEDuplicateTransient
