Balancing reflections with Specular Roughness

“

- [Instructor] Carrying on from the previous movie, I've got these sculptures selected in the viewport. I'm displaying the standard service attributes, and I've got the Arnold render view running in interactive production render mode. Let's talk about specular roughness. Roughness is a measure of how porous a surface is. And with a value of one, the surface will be rendered as if it had many tiny, micro-fine deviations in its surface. And that will cause the light to scatter around. It's easier to see if we have no diffuse or base color. I'll set the base weight down to its minimum of zero. With a specular roughness of one, we get this kind of matte finish in which the light is being scattered around in all directions. As we reduce the roughness, we increase the glossiness or shininess of that surface. If we bring it down to around 0.4 or 0.5, we get a kind of semi-gloss surface. If we bring the roughness down to its…
