Create a Blueprint Interface.
In the Actor/Actors that you want to use this interface on, Edit your blueprint and click on Class Settings.
In the DETAILS panel you will see a section called Interfaces, Add the BluePrint Interface you just made.
Now on your Overlapping BOX/VOLUME Trigger event the overlapping actor drag off and type in does implement interface? Select your interface and use a branch that if true use the lighting or w/e.
Hello good people, i was wondering how you would go about triggering an event (light visability) by having spesific actors overlapping a collision box in BP’s? Im pretty new to ue4 so i dont see an obvious way to do this, i have tried “has tag” and “is child” (with childing(?) the actors to the triggerbox), but i feel like i am missing something…
The easiest way to set this up would be very much appreaciated 
Thanks for the swift reply, unfortunately that didnt work ;/
But! I did manage to get the “Is Child?” node to work when i carry the objects, but i am launching these children with “Add Impulse”, and then it seems to ignore them,… Any idea why that is? Almost like it doesnt register them in time to call the event?
