Would Unity support local GI like the new NavMesh Component in future?

Not only rely on a scene.

 

I think this approach - leaving the scene structure as much as possible - is pretty important. In my opinion, occlusion, GI, and others should be detached from the scene. Not sure if the data structures for these things, specifically GI, would be able to work in a component form, but it'd be the best if that would be possible. With all the focus on squeezing as much optimization as possible, it's odd we still have slow load times due to not having much control on scene loading and scene data.

I personally see a future where we can completely drop Unity's Scene structure, and create our own system, if we so desire. That fits Unity very well, in my opinion. but this is just a dream at the moment.

Of course, the Navigation Components are still unfinished. Which is odd as well. Unity is generally very good at getting features out, other than I guess the Input System and Navigation Components. (Probably others I missed)
