Blender tutorial shows how to delete materials from object and from project in Blender. In Blender, we can delete unused materials from object in material slot, also we can delete unused material from project in Outliner. If there are there many material in one object, we can delete the material directly by below steps. Sometimes there are too many unused materials and shaders in the scene in Blender, to speed up our work process or to optimize the scene for minimizing the file size. We can remove unused material in Outliner by few steps shown below part of article. This is the scene that we set previous for metal material setup, for this case study, we are going to remove “Shiny Gold” Material in the second ring. Hope this helps.
