Couldn't get the right coffee color and the thickness of glass cup I was trying to follow the coffee cup tutorial by Blender Guru on https://www.youtube.com/watch?v=fdWUjEMzDhg&amp;t=235s
However, I have two major problems with my own project:
1， I couldn't get the right coffee color changing the &quot;Color&quot; and &quot;Density&quot; in Materials -&gt; Volume (Volume absorption), I've also tried changing Base color in Principled BSDF but I got nothing close to real coffee color. Both colors don't work the way I thought.
2, There's no gap between liquid and the cup outer wall (no thinkness of the glass cup).
I've given a try for the glass material, it's not completely accurate but in my opinion it creates the illusion. I haven't changed the coffee material itself.
