How can I change the order of layers if I have a static mesh superimposed on me?

How can I change the order of layers if I have a static mesh superimposed on me?

can you give an example? I don’t follow what you mean by “superimposed”, and “Layers” can mean a bunch of different things.

is this a separate Actor with a Static Mesh overlapping a given Actor/Pawn/Character?
is this Static Mesh a component of the Actor/Pawn/Character that is overlapping something else in the Hierarchy?
is there something else I don’t understand?
