I got the chance to work with Jonas Ronnegard on his first Substance Masters Pack! I built a mossy rock material for the tutorial pack, with graph commenting, recordings of the development process and even some marmoset files for presenting. I tried to build the graph as cleanly and flexible as possible to illustrate good working practices. The renders you see here are of different random seed values of the same graph. Quick time lapse video at the end!
