microroughness control
can we add microroughness controls for materials? Maybe as a part of upcoming principled shader?

Re: microroughness control
What is the purpose of micro roughness? How is it different from current roughness
Re: microroughness control
Yes microroughness is present.
But if you know of a better solution please, suggest, advise...
I'm still looking for best shader model, one that would be worth of implementing successfully (for starters, more efficient with specularity - producing less noise & less energy loss).

Re: microroughness control
So, for example in fstorm you have this "angle affect" parameter in material that allows to controll roughness at grazing angles. There is similar feature in thea render and it can be somewhat emulates with nodes for cycles.
Re: microroughness control
Isn't it called "sheen" in Disney's principled shader? Otherwise I don't get what you're after
Re: microroughness control
A surface with micro-roughness has several reflection contributions, sheen is an additional specular component at grazing angles to model e.g. light interacting with cloth fibers. Retro-reflection and diffuse components are the other ones. Disney's Principled Shader implements them.

here's basicaly what I'm looking for: https://blenderartists.org/t/micro-angl ... 691900/340
I know this feature is present in fstorm material. It's a nice fancy effect that helps boost realism in some materials.
