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 is 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. 

Add-on functionality

  • Just press the "Clear materials" button
  • M-Cleaner will automatically clear your scene of duplicates
  • "Merge by name" cleans materials only by their names (destructive!). It clears materials with .001, .002, etc names.
  • If the "Remove unused" checkbox is on, duplicates will be removed from the scene immediately. If this checkbox is off, duplicates will remain in the scene with 0 users and will be deleted using regular Blender tools during the scene saving.
