Create bar
When you first open Hypershade, the Create Bar panel appears at the left. From this panel, you can choose among nodes that let you create different types of rendering effects.
Click one of the two categories to display the nodes that you want: Maya or Mental Ray. Different types of nodes are nested in sections.
Select one or more sections.
Only the nodes in the selected sections are displayed in the right
panel. To clear your selection, press 
in the search area.
Use the scroll bar to navigate through the Create bar and click to create the node that you want.
You can hide or resize the Create bar, or, you can customize the display of its icons. For more information, see Hide, resize or customize the Create bar.
Enter the keyword for the render node that you want to create. As you enter a keyword, the right panel of the Create bar updates in real time and only render nodes with names that match what you entered are displayed.
You can create a Favorites list so you can easily access your most commonly used nodes.
To add a shader to your Favorites list, 
drag
the shader to Favorites. Alternatively, you
can 
the
shader and select Add to favorites. The Hypershade sorts
your favorites in categories to enable you to locate your shaders
easily.
