Blender add-on for automatically finding and removing duplicates of materials from the scene.
When you add objects from previously saved blend-files, external libraries, various asset- and kitbash- sets to the scene, your scene filled with a large number of identical materials. With dozens of them in complex scenes. “M-Cleaner” finds the equal materials in the scene and removes duplicates, reassigning the single unique material to the objects.
