Material Studies: Minerals

Hello everyone, a brief breakdown of my approach to preparing and shading a mineral asset inside of SideFX's Houdini, using ZBrush and rendered in Arnold. Hope this is informative, so please let me know! Always keen to hear about how this kind of information can be delivered better, as well as any suggestions for further studies.
You can grab the mineral asset here: https://drive.google.com/file/d/1bk7h67TT7DMUcdvWpLQdKRxaHknK6qdk/view?usp=sharing
