Event Actor Begin Overlap Only Triggering BP Actors

How can i get the Event Actor Begin Overlap node to detect any actors, even those that are not blueprints, i am trying to change the material of an object when it overlaps anything, but it only works when it overlaps blueprint objects.

Double check the collision channel settings of both your blueprint and the object in question. Also make sure you have set ‘Generate overlap events’ to true. Finally see if your objects have a collision volume (simple or complex).
