Adapting a basic material from Specular setup to Metallic

For a better understanding of the differences between Metallic and Specular workflows, we will modify theAlbedo and Specular/Smoothness maps that are used on a Specularsetup 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

This recipe builds on the previous one, so make a copy of that project and use the copy for this recipe.

How to do it...

To create a basic Material using the Metallic workflow, follow these steps:

1. From the Project panel, select the battery_prefab element. From the Inspector, access its Material (named Battery_MAT) and change its Shader to Standard (as opposed to its current shader – Standard (Specular setup):

2. In the Projectpanel, find the Battery_specular map and rename it Battery_metallic. Open it in your image editor (we'll use Adobe Photoshop to illustrate the following steps).
3. Find...
