Syntax
EActorUpdateOverlapsMethod UpdateOverlapsMethodDuringLevelStreaming
Remarks
Condition for calling UpdateOverlaps() to initialize overlap state when loaded in during level streaming. If set to 'UseConfigDefault', the default specified in ini (displayed in 'DefaultUpdateOverlapsMethodDuringLevelStreaming') will be used. If overlaps are not initialized, this actor and attached components will not have an initial state of what objects are touching it, and overlap events may only come in once one of those objects update overlaps themselves (for example when moving). However if an object touching it does initialize state, both objects will know about their touching state with each other. This can be a potentially large performance savings during level loading and streaming, and is safe if the object and others initially overlapping it do not need the overlap state because they will not trigger overlap notifications.
Note that if 'bGenerateOverlapEventsDuringLevelStreaming' is true, overlaps are always updated in this case, but that flag determines whether the Begin/End overlap events are triggered.
