Substance Designer beginner tutorial: Making an ice floe PBR material

I decided to make some Substance Designer tutorials for beginners from time to time, where I show how to make good looking materials with a relativly small graph. These are not timelapsed and I am explaining some stuff. What do you think about this? Should I make some of these more often, or should I stay with more complex materials and timlapses? However, in this one I want to show you how to make an Ice floe PBR Material without much effort. Hope you like it! ******************************* Music: Talkline Nr. 7 by https://musicfox.com *******************************
