@Jacky (Jacky) posted a new topic, subject "Is it possible to hide an emitter when its line of sight to the camera is blocked?". It read:

   Use Custom Bounds. Select anywhere on the empty area in cascade and then check out Occlusion tab in Details panel.

So @UndyingSpartan (UndyingSpartan) replied

    Hi, folks. I'm trying to create a lens flare, using a particle system, but I can't seem to figure out how to ‘hide' it when something blocks the actor's line of sight to the camera (like in picture #2).
    
    Is this possible in Cascade or would it need to be done in Blueprints, somehow?
    
    Any help is appreciated, thanks.

    @Jacky: You, sir, are a life saver. That worked perfectly, thank you!
