Material Editor > Material Name field

The Material Name field displays the name of the map or material. Default material names are "01 − Default," and so on, the number changing to reflect the material's sample slot. Maps are named "Map #1," and so on.
You can edit this field to change the name of the material in the active sample slot. You can also edit the names of maps and sub-materials assigned at lower levels of the map or material hierarchy.
In prior releases, material names were limited to 16 characters. Now you can assign material names of arbitrary length. The name of the material is not a file name: it can contain spaces, numbers, and special characters.
This field also functions as a drop-down list. At the top level, it shows only the material or map name. At lower levels of the hierarchy, drop the list down to see the names of ancestors to the map or material. The top level is at the top of the list, the current level is at the bottom, and intermediate levels appear between them.
To give a material a different name:
Edit the name field that appears below the Material Editor toolbar.
The name of the active material appears in the title bar of the Material Editor dialog.
If a material that you want to change has been saved in the scene but not in the Material Editor, you can load the material by getting it from the scene.
