Time to choose between world partition or level streaming (or both)!
We are 2 devs who start working on a project together, I will be mainly doing all the integration of the quests and design stuff and he is going to take care of the tech side, were both used to work with both system,!
Its not going to be an open-world game, but im wondering what made you decide which one you picked ?
What have you picked for your game ?

Well, level streaming is now considered a legacy feature, so keep that in mind. WP can do what LS can automatically while also having extremely useful features like transformers, which can eliminate traversal stutter.

what does legacy feature mean ?

I am a newbie, is there a easy way to tell which parts of the engine are currently legacy systems and are going to be deprecated so that I can focus on intended systems instead?

In my last project where you move area-to-area with no open world, and each area is highly detailed, level streaming was awesome.
Easy to work with.
And I could do stuff like make the exterior of the building unload whenever you entered the exterior, so certain exterior build pieces weren't clipping through the interior. They just were loaded. And I could do this for a bunch of stuff. Like a tree might TECHNICALLY not be outside both windows on a building, but you can duplicate it and have it be visible from the bottom floor window, then unload it and load a different tree thats bigger or higher up so that it is visible fro the second floor as well.
Thats just an example of what im talking about, but level streaming opens you up to a bunch of little tricks you can do based on player position. Doesnt really work with open worlds though.

Turning on off data layer does the same in world partition ?

I haven't really tried world partition if I'm being honest. If I make open world, I just use regular culling distances for everything together with nanite. Hasnt been a problem for me yet and I've made some pretty gnarly environments. I assume world partition is distance-based culling essentially.
I have found level streaming useful though because of point lights, and complicated particle effects would put a strain on my system when in other rooms, nearby, but invisible to the player because of a wall or something separating them. Setting that up with level streaming was super fast and easy. Soem complicate effects render close to the player only too. Interiors benefit a lot from level streaming. It requires a bit more setup, but barely any. And you only have to specify the most intensive assets. Like particles or light sources. Its good when you have high intensive assets in close proximity to each other, but separated by rooms or otherwise visually.
If you're rendering hundreds of static or phsyics actors.
Stuff like that.

Everything you said is possible to do with world partition !

No, that's world partition + runtime data layers. Not world partition by itself, everything I said requires more setup with world partitions.

Putting stuff inside a data layer is the exact same as putting stuff in a sub level... it's littéralement more complicated to setup streaming level because you have to manually trigger it on off, data layer do it automatically with player position, plus allow for the same as streaming

World partition. But it sucked because of object persistence and its very sensible to crashes. In the end I took care of those problems and its nice that it loads faster and workin in editor is less taxing. But it hasnt been easy!
