ArtStation – Substance Fundamentals Tutorial

Could the title be changed for some like:
ArtStation – Substance Fundamentals Tutorial Part 1-4 by Daniel Thiger ?
So if someone is searching for the missing
Gumroad – Substance Fundamentals Part 3: Voronoi Cells and Shapes by Daniel Thiger
could know that is possible to find it here as this is just a collection of the first 4 parts of his tutorials

Unless the Artstation tutorials and the Gumroad ones differ by a lot
Thx
