Unreal Lighting / Optimization Expert Wanted for Disney Theme Park Project

Hi everyone!
I’ve been recreating EPCOT Center’s Future World as of opening day 1982. My primary experience is in 3d modeling, so I’m looking for knowledgeable Unreal folks to help sand off some of the rough edges.

In particular, I would love to improve both the lighting/atmosphere, and also the optimization. I feel the project can look quite a bit better than it currently does, and it’s also tough to run on anything other than a top gaming PC right now.

I’m hopeful this won’t involve a tremendous amount of effort, as everything is already inside Unreal, connected to a github upload. It’s mainly about polishing what’s already in there.

I’ve attached some images, and you can see the progress of the project at
