How do I recreate these cutscenes' background?

So I want a cheap and empty background for my actions kinda like this without stressing out the performance with models, how would I go about that?

I tried to use an inverted ball and make reflectance 1 then set the skybox to urban city, but that doesn’t work well.

And how should I go with the edge of the base? Cause if I use fog you probably cant see backgrounds and I want it to be usable in multiple areas. (Example: Urban area will use urban background and Forest area will use wilderness background)

just use a skybox with some fog and a floor. if that’s not enough, you should consider billboards

Billboards solution doesn’t work anymore. Also normal skybox wouldn’t work cause I’m accounting for spaces incase the cutscene overlaps with other models/buildings vertically

What do you mean by the last one?

Because I spawn in cutscenes in the workspace I thought if I spawn it sometimes it might cause some mishaps like in the cutscene you can see a building in the background that you’re not supposed to see

Oh, just use fog like in the game for that. Or if you have an issue, the only option you have is using UI (SurfaceGUI, BillboardGUI)

Yeah, but fog looks rather bland no? And I do want it to have some background (like the skyscrapers in the video) Oh well, ill keep looking
