Why fracture (chaos mode) is not played

I created simple fracture (chaos mode) on my static mesh window.

I put. thisGeometryCollectionComponent on my game map but after the game start, nothing happend.

I created simple BP with only one item - GeometryCollection (my created collection) and put into my game, nothing happend.

Why?

I know it’s not a lot of information, but I don’t know what else to write.

Looks like, that problem is that object is to small, I am using static mesh window
