[Level design] Static Mesh prefabs, To blueprint or not?

Hey Folks,

So currently we are experimenting a bit with our Level design workflow.
At the moment our artist has made a bunch of level pieces (Corridors, Rooms, etc).
These pieces consist out of static meshes and are put together in a Blueprint. Example, a wall + floor + ceiling piece would make up part of a room.

This would mean though, that after a while there will be a extensive amount of blueprints in the scene.
Now I have noticed it is possible to convert these to a single static mesh.

So my question is, for optimization sake.
Would it be a good idea to convert these Blueprint prefabs/Level design pieces to a static mesh?
Or is it not worth the bother?

Thanks in advance!

From what I’ve read so far, using Static Meshes should be heavily less CPU expensive, but I also believe it’s related to the “complexity” of the meshes.
Of course if you’re planning to use over and over and over the same set pieces (room, floor, etc) using a blueprint is definetely a better option, otherwise you end up spending hours creating the same level multiple times.

Yea we figured that as well. Even though the Blueprints are empty, I was wondering if it would make a big impact on memory usage etc.
