I'm trying to figure out how to determine if a actor has a parent ref in a script, i've tried things like: if Target.GetParentRef == 0 and if Target.GetParentRef.GetFormIDString == "00000000" I can't find anything that really works. Is there something obvious I'm missing? Also, is there a way to determine if an actor is unique? (As in, "Cass", not "Wasteland Settler") Thanks.
