What is the best way to create many levels with similar aspects (child level), 4-23

I am making a game with many levels but they all share many common aspects including lighting, volumes, and more. I found the “child” blueprint function really helpful as it allowed me to create many child blueprints that inherit from the parent. Is there a way for me to do this with levels? Is there a way with level streaming?

Yes. You do it with level streaming. You create a main level and this level you can load several sublevels.

There are also lighting levels possible with pre backed lighting which you can switch on/off etc.
