Won’t a real place have stairs instead?
We could do something like the thing which is done in CS, adding invisible clips to the stairs so they function as ramps but look like stairs, so your RC problem will be fixed.
I don’t think the lobby will look good if the stairs were replaced with ramps.
Not replace. Add sections, like in the second screenshot.
I hope they do this with the subway escalator though. I always assumed they’ve remained unfinished and static because they want to make it “real” instead of a conveyor belt.
