Roughness Control on specular material

[Flyx]

Hi !

is there a way to control both refraction and reflection roughness separatly ?

I understand that it is the correct physical way to do it, but when working on an packshot or animation, i always find myself needing to set different value for the both, less realistic, but much nicer to the eyes !

Try using a scattering medium and using scattering as the refractive "roughness". Adding a Schlick node with a high value (0.5-0.9) will also help recreate the standard "roughness" look as opposed to a foggy look.
