Roughness

A node of the Style graph, in the Inputs group.

The material channel: how rough each pixel's surface is.

Takes: render (render) · Gives: scalar

What it wires to

Its render input takes a render, which these give: Render.

What it gives, a scalar, goes into: Lines, Shading, To palette, Add, Blur, By material, By part, Cavity, Divide, Edges, Fraction, Glint, and 19 more.

In the app, drag a wire from one of its dots: every dot the wire fits is ringed.

How it fits with the rest: the Style graph in the manual.
