Occlusion Culling in Unity

[vagrant atlas]

I'm trying to wrap my head around occlusion culling and how it works. My usecase is that I have several maps created as prefabs, how do I go about using Occlusion Culling?

I tried baking OC by editing the prefab but it wouldn't complete and throw an error, only got it done when I pulled the map prefab to the scene.

Would anyone clarify this to me?

Can it be made per map prefab? Do I need multiple cameras?

If you're spawning things into the scene as prefabs, it won't work at all

Unity's occlusion culling solution requires occluders to be in the scene, static, and prebaked

[vagrant atlas]

So if I have multiple maps and I need different occlusion culling data, I am going to need multiple scenes?

yes

That's if you use Unity's built in occlusion culling solution

other solutions are available on the asset store that have different sets of requirements afaik
