Since obsidian is dark, reflective and blends with my background template, the final presentation was a challenge.
Bonus animated gif.
With all unused nodes discarded, the final graph is really simple.
Thank you for viewing!
SD Material study: Obsidian
This is my take on pure obsidian.
As with other materials, I aimed for aesthetics over realism.
This study took a long time, but I'm happy with amount of new knowledge gained from it!
