To save material layers:

1) Navigate to or create the material library folder to store your materials

2) Click the + button in the bottom of the library window to create a new material set

3) Set a name for the material layer (Like V4 Vascularity Layer or some such)

4) Click the Material Layers radio button

5) Click the Select Layers button. A dialog opens and lists all the layers in each of the materials you created. You can Select All, Select None, or check only the ones you want to include. Then click OK.

The material layer preset will be saved into the location you choose, using an MLC extension
