KeyShot Material Study: Bead Blasted Aluminum. In this KeyShot tutorial I’ll walk you through how to create the look of a bead blasted aluminum material. This is the one you’ll typically see on i.e. macbooks, on the bose soundlink mini and on a bunch of other product. I’ll create the material using the metal material type with two procedural noise textures in the bump channel and a noise texture in the roughness channel.
