Values

Name	Description
RF_NoFlags	No flags, used to avoid a cast.
RF_Public	Object is visible outside its package.
RF_Standalone	Keep object around for editing even if unreferenced.
RF_MarkAsNative	Object (UField) will be marked as native on construction (DO NOT USE THIS FLAG in HasAnyFlags() etc)
RF_Transactional	Object is transactional.
RF_ClassDefaultObject	This object is its class's default object.
RF_ArchetypeObject	This object is a template for another object - treat like a class default object.
RF_Transient	Don't save object.
RF_MarkAsRootSet	This group of flags is primarily concerned with garbage collection.
RF_TagGarbageTemp	This is a temp user flag for various utilities that need to use the garbage collector. The garbage collector itself does not interpret it.
RF_NeedInitialization	The group of flags tracks the stages of the lifetime of a uobject.
RF_NeedLoad	During load, indicates object needs loading.
RF_KeepForCooker	Keep this object during garbage collection because it's still being used by the cooker.
RF_NeedPostLoad	Object needs to be postloaded.
RF_NeedPostLoadSubobjects	During load, indicates that the object still needs to instance subobjects and fixup serialized component references.
RF_NewerVersionExists	Object has been consigned to oblivion due to its owner package being reloaded, and a newer version currently exists.
RF_BeginDestroyed	BeginDestroy has been called on the object.
RF_FinishDestroyed	FinishDestroy has been called on the object.
RF_BeingRegenerated	Flags.
RF_DefaultSubObject	Flagged on subobjects that are defaults.
RF_WasLoaded	Flagged on UObjects that were loaded.
RF_TextExportTransient	Do not export object to text form (e.g. copy/paste). Generally used for sub-objects that can be regenerated from data in their parent object.
RF_LoadCompleted	Object has been completely serialized by linkerload at least once. DO NOT USE THIS FLAG, It should be replaced with RF_WasLoaded.
RF_InheritableComponentTemplate	Archetype of the object can be in its super class.
RF_DuplicateTransient	Object should not be included in any type of duplication (copy/paste, binary duplication, etc.)
RF_StrongRefOnFrame	References to this object from persistent function frame are handled as strong ones.
RF_NonPIEDuplicateTransient	Object should not be included for duplication unless it's being duplicated for a PIE session
RF_WillBeLoaded	This object was constructed during load and will be loaded shortly.
RF_HasExternalPackage	This object has an external package assigned and should look it up when getting the outermost package.
RF_AllocatedInSharedPage	Allocated from a ref-counted page shared with other UObjects.
