@EvanHammel - I checked all attributes of the actors that appeared in the render and those that were not and they were identical, BUT this actual lead me to consider the logic that I have done so far in the level blueprint and once I disconnected EventBeginPlay, the actors appeared again, so I guess the logic for OnActorBeginOverlap (which would toggle the actor hidden in the game attribute) would affect the visibility in the render; anyway I’m glad I found the root cause and thank you for your support
