How to create same level but with changes

[lost trout]

Unsure if this needs a really long complex answer but I am unsure how to effectively google this so I have come up with 0 helpfull results thusfar. I am mainly looking for a global/fundamental answer rather than super specific

For the gamejam my project (unreal engine) will contain the same house except for different events happening, different item locations, and some stuff like that (Think 2016 Tattletail or P.T.). Initial idea was to create a level with the house, and then duplicate that level and make changes there to what I need it to be. Problem with this is that if I make changes to 1 level (let's say I change an entire room after testing) I would have to repeat this same change over multiple levels rather than just changing it in one place. How could I create this to where I only have to change 1 thing, but it updates everywhere?

Currently looking into Level Streaming. If this does what I want i'll update this thread to fixed

Never used levelstreaming, so I can't tell much about this tbh. A quick creative but probably not optimal solution that comes to my mind is to make the rooms each a blueprint themselves. So you just place the roomblueprint that includes the items etc in the level. You could then just make charges in the same blueprint like on a simple book switch (change the Position of the New items) or change the whole blueprint, like kitchen1 to kitchen2 at the same Position. Both could would work without needing a whole new level.

Ok, so you’re talking about having variations for the same level correct?
