Can I recreate this sky in UE5 from old assets?

I am trying to recreate this sky from assets from a game that was created on version 4.12.

Is this actually possible?

I ripped the files from the game and there are a number of files that reference the sky.

any help would be greatly appreciated

The name of the asset would be nice to be able to verify.

What name are you referring to, can you elaborate?
