Re: There's something very weird looking about that
Now it makes sense.
The article was just confusing because it talked about how Fortnite is the only game where breasts behave like they do in real life instead of bouncing around all the time, then it talked about how perfectly somebody had modelled the physics of these ones, to be just like real life.
The issue is that they're the only realistic part of a cartoony character, that's more understandable.
As for how long they spent modelling them, I'd suggest they wrote #include <libraryname> and then added two flags to the model. Breast jiggle is modelled using the same algorithms as hair jiggle so it's not like the libraries aren't out there.
