OK, thanks for pointing those out!
Many years ago when I was trying to render my first projects, I used Physical, but then, V-ray gave better results in terms of realism. So I kind of never looked back. So comparing to other renderers (Redshift, Corona, Vray) C4D physical renderer can offer same results in terms of realism?
But I do archviz only.. so I don´t know does that plays a role.
