Substance Designer from Pluralsight. That page has so many good tutorials. I really enjoy how my texture ended up. I posted it on my Art station https://www.artstation.com/artwork/592aJ. Got a like and a new follower right away. That’s nice. I made this texture by following the tutorial but adjusting it for my needs. I will use this for my mountain texture.
