Hi,
Right now RPR's material presets are complex node setups that are not very accessible / editable. In my humble opinion it would be more user-friendly and yield a faster workflow if the material presets would use the Uber Shader whenever possible, unless a material requires a scientifically accurate approach.
Thanks,
Metin
Well whadya know, the just released RPR version features this. You guys can read my mind, I'm in awe.
Thanks!
