Those controller scripts are used in all example scenes for assigning proper dissolve keywords and properties to the materials.

Controller scripts update only those materials that are in the **Materials** array of those scripts.  To easily add materials to the controller scripts, lock their Inspector window, then select required game objects and from script's menu choose **Add Materials From Selection**.
