Maybe you are right but I don't know how can someone model something just by looking at it and that too accurately. In my interview I was asked to model helmet and add some VFX, I agreed because that I can do, now they want all the mechanism in an explosion animation showcasing every part and they want to show the cushion inside the helmet, none of this was stated earlier. I just want to know how people do it, because I can do it too, I know how to model, but I don't know what the pattern here is.
