My understanding is that if I untick the box then that component shouldn’t be overlapped by any overlap function, however I am seeing that SphereOverlapActors (therefore also SphereOverlapComponents) still overlaps my component. Am I missing something or is this intended?

Hello! This option touches only notification events, virtual functions, blueprint callbacks, but not overlapping itself. So, component can overlap in both situations of option is TRUE or FALSE. However, If option is FALSE, this component will NOT call OnComponentBeginOverlap, NotifyActorBeginOverlap, OnActorBeginOverlap when starting to overlap something… If you want to exclude component from collision calcs for some logic then just set NO\_COLLISION type to it…

Kehel18, you should change this to an answer instead of a comment so that the OP can mark it as answered.
