You can delete a specific material using the Object List, or right-click a model to delete any unused materials in your scene.

To delete a material

1. Right-click the material in the Object List, then select Delete Material from the menu that appears.

To delete all unused materials in the scene

1. Right-click a mesh and select Delete Unused Materials.
   NoteIf the deleted material(s) have previously saved texture maps, the maps are still left in the associated <filename>-files directory with your model file. (See Save or export paint layers for information on how Mudbox saves textures with your scene.)
