I am wanting to make Hartsfield-Jackson International Airport in UE4 with the most accuracy as possible. I have floor plans and some general images for references, but I don’t know how to start designing the floors.
There are multiple levels to the Airport and there are 8 terminals with at least 3 levels per terminal. The terminals also have stairwells, elevators, and escalators that connect them. Under the whole airport runs a train that transports people between terminals.
How do you suggest approaching this so that all levels work together and are as accurate as can be?
How would you suggest to build walls, insert windows, and add openings for level changes?
