hi there, it s there to use normal maps.
that aims to add lots of details, without adding geometry. (kind of advanced bump with 3 dimensions)
more info there;

those maps are “blue looking” like these :https://www.google.fr/search?q=normal+maps&client=firefox-b&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiE2YjC4M3OAhUD1hoKHeY1CXsQ_AUICCgB&biw=954&bih=463

try to download one and apply it to see what it does :wink:
