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.

Mapping methods
When you map a 2D or 3D texture to an object, you connect it to an attribute of the object’s material. If you are selecting a 2D texture, you can right-click the texture to select the Mapping method you want to use. Normal mapping is the default, but you can also select Create as projection, or Create as stencil.
