Spawn new Object after the existing left the area

Hello together :slight_smile:

i need your help^^
Im working on a little VR project for the work.
What i need is a Blueprint that respawns an object (pipes in my case) after u took it away from place. Ive tried to use a trigger Box and let it spawn a new Pipe at a TargetPoint, after the existing left the trigger Box, but nothing happens… And google couldn’t help me until now :confused:

Im very new in working with UE blueprint so explaining pictures would be great ;D (if possible^^)
