Hi,
If you’re doing this in C++, then in your actor’s constructor, you must have this two enabled:
PrimaryActorTick.bCanEverTick = true;
PrimaryActorTick.bStartWithTickEnabled = true;
If this is a BP class or you’ve created a BP based on this c++ class, you must make sure that the same settings are also enabled in your blueprints. Open your BP, on the right panel, under Actor Tick, make sure Start With Tick Enabled is checked.
Hope this helps.
