This material was created by Sanctus and will soon be added to the Sanctus Library add-on.
Procedural Artist Sanctus has demonstrated a new procedural material that will soon be added to the Sanctus Library add-on, the artist's downloadable collection of procedural materials made in Blender. This time, the artist teased a cool-looking destroyed brick wall material that will be added to the library with the next update. According to a short demo shared by Sanctus, the material promises to come with customizable settings that will allow you to tweak the destructions and fallen-off pieces of plaster to your heart's content.
Recently, the artist also released the 2.0 update to Sanctus Library. The update brought several new materials, an improved asset browser, the ability to create and modify your own materials, a new shader tools panel, and more. You can check out Sanctus Library 2.0 here.
