Zbrush Materials - Bark Explorations

Zbrush sculpts used as a base.

Various bark studies made for my personal practice and enjoyment. My goal was to study the shape of different bark types.
Since I am using a Zbrush/SD combo to get the most accurate results I could, those materials are not procedural.
Renders are made with marmoset toolbag and PBR Render in SD.
