Trying to run “Cursor over event” in particle system

I want to create simple thing.
When cursor passes over the actor, in the corner a sign appears with information about him, like this (cursor on cube).
enter image description here
But when I try to doing same for particle system nothing happens (cursor on PS)

enter image description here
Some settings:

  • Generate overlap events in PS blueprint enabled
  • PS doesn’t have collision module in emitter
  • Overlap events in controller enabled
  • I’m also Set collision enabled in construction script for PS

Particle system has own On begin cursor over event, it means (as I understand), that I can implement this mechanic without adding sphere collison as child. Or I cant?

Thanks for help!
