How can I have windows in my level all break when I reach a point in that level?

how can i for example be walking in a small hallway and when i reach a point that all glasses (windows) breaks in the same direction?
so somewhere with many windows that will kind a explode or breaks, so im thinking with the box trigger but what can i do to link it and let all those windows break if i walk in that box?

In your level blueprint you can call the overlap event for the box trigger(whose specific name is in your scene outlier when you are in the viewport for the level) and then call whichever functions you need to make windows explode.

Do I need to animate that window in an different program or can I do it with a destructible mesh in unreal engine?

You could probably use a destructible mesh if you have the performance to spare. I haven’t dealt with them much but I think you can use them wherever you can afford to.

Ok thanks for the help
