Duplicates VS Prefabs in Unreal 4?

Hi all,

I’m creating my first environment in UE4, but wanted to clarify the difference between Duplicating an Object vs Prefabing it then adding more prefabs of that object to fill the scene.

I know in Unity, duplicating models is like adding more geometry as the duplicate is translated as another object. I’m not sure if Unreal does something differently with duplicates or if it’s the same concept.

Please let me know your thoughts.
Thanks in advance!

If you’re duplicating a mesh in the content browser/library then that would be an additional mesh that wouldn’t be referencing the original at all so having both the duplicate and the original in a scene would take up 2x as much memory.
