Adapting a basic material from Specular setup to Metallic

For a better understanding of the differences between Metallic and Specular workflows, we will modify the Albedo and Specular/Smoothness maps that are used on a Specular setup material, in order to adapt them to the Metallic workflow. The material to be generated will feature both metallic and non-metallic parts, with various smoothness levels.

Getting ready

For this recipe, we have prepared a Unity package containing a battery model and its original material (made with Standard Shader—Specular setup).

1. Import the battery_prefab Unity package into a new project.
2. From the Project view, select the battery_prefab element. Then, from Inspector, access its...
