ONLY WORKS WITH 2018 or higher versions of Zbrush. This is the 3rd dragon scale brush available by me AND its also the most robust: including 37 different VDMs. This is how I created the scales on many of my creatures. If you like the brush. Happy sculpting!!! IF YOU LIKE THE BRUSH, if would really help to give it a 5 star rating so we can get this brush visible to more artists.
