Reply To: Unable to reproduce results with Principled BSDF
Well, if this is to learn, then great!
Practically, when you want fast and easy PBR, then the Principled Shader is often the way to go, but you lose a bit of control..
Just for educational fun, here are a few renders; from left to right: your Node setup, Kent’s Node setup and finally mine:
You seem to lose some definition (shape information) in the dark areas, they become a bit ‘muddy’. Overall it looks a bit more flat (less highlights in the orange and green).
But still a great effort! (You did forget to connect the Normal Map to the Diffuse Shader…I connected that in this render..)
