Hey prof - can you point me to any solid resources on building PBR materials from real-world reference? I’m just kind of going by eye and intuition right now but I know it’s more of a science than that.
Blender’s Principled BSDF is based on Disney’s work. Maybe you’re looking for something more advanced, but Andrew Price (Blender Guru, the donut guy) has some decent videos talking about how to create realistic materials with it. I don’t have any links at the moment, but they should be easy to find on YouTube.
