This piece is based on an actual plant that I visited in 2012 :
A steel factory, located on an island in Tokyo Bay, not far from the Haneda airport or the town Yokohama, for the people familiar with Japan.
I can recommend the boat tour to see it upclose : )
For the assets : the tubes, chimney, handrails, lamps and platform were done this week.
Scaffolding : CC0 assets from feivelyn on sketchfab.
Character and most of the pipes : Ian Hubert
