Is they a way for box collider to run the event when not active

Hi I am trying create a floor using cubes that show when the player stands on them and are destroyed when not. The floor goes for infinite distance in the x-y plane.
The only way I have been able to do it so far is to create blueprint of the cube and another blueprint to cerate the floor using for loops and spawn actor form class to make the floor and make visible and invisible when the player on or off the cube but can only make a small floor before it wont load. I am hoping there is away to spawn the actor at a trigger box location if nothing triggers the box
Any help would be great Thanks Rob:)
