creation of materials, texture nodes allow
the creation of textures, while compositing
nodes provide a means of assembling and
enhancing images or movies.
Before attempting to use nodes for any
specific task, it is essential to know how to
add, arrange, and link nodes. The first step
is to open the node editor window. By de-
fault, the material node category is select-
ed, so to demonstrate the process of using
nodes we will start with this category. Make
sure an object is selected in the 3D window
and that a material has been assigned. If you
use the default Blender scene, the default
cube object is selected and in the properties
window - “Material” button, the preview
panel shows a gray sphere; this sphere is
showing the default color of the default ma-
terial named “Material,” which is applied to
the cube (Figure 18.2).
