M-Cleaner

What is this for

"M-Cleaner" is the 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 (non-destructive)
• M-Cleaner will automatically clear your scene of duplicates
• "Merge by name" joins materials by name (destructive) - joins materials with .001, .002, etc.
  
• 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.
