I spent tonight creating a 3 part substance set of Snow.
I've always wanted to have a tackle at snow but I didn't want to do one state of snow since it may have been too easy so I felt it would have been a fun exercise to build 3 versions of it... Soft, Rough and Slushy.
This was roughly a 3-4 hour build time and other iterations came quickly after the first initial constructed graph.
Built entirely within Substance 6. Rendered in Marmoset Toolbag 3.
