uint32 bCanBlueprintsTickByDefault: 1
Controls whether Blueprint subclasses of actors or components can tick by default.
Blueprints that derive from native C++ classes that have bCanEverTick=true will always be able to tick Blueprints that derive from exactly AActor or UActorComponent will always be able to tick Otherwise, they can tick as long as the parent doesn't have meta=(ChildCannotTick) and either bCanBlueprintsTickByDefault is true or the parent has meta=(ChildCanTick)
