ial window but is visible only in the Node Editor window); the new nodes
appear already selected.
4. Again press Shift + A in the Node Editor window and this time add a Mix
Shader node.
5. Press G to move it on the link connecting the Diffuse BSDF node to the
Material Output node (you'll probably need to first adjust the position of
the two nodes to make room between them). The Mix Shader node gets
automatically pasted in between, the Diffuse node output connected to
the first Shader input socket, as shown in the following screenshot:
6. Left-click with the mouse on the green dot output of the Glossy BSDF
shader node and grab the link to the second input socket of the Mix
Shader node. Release the mouse button now and see the nodes being
connected.
7. Because the blending Fac ( factor ) value of the Mix Shader node is set
by default to 0.500 , the two shader components, Diffuse and Glossy ,
are now showing on the cube's surface in equal parts, that is, each one
at 50 percent. Left-click on the Fac slider with the mouse and slide it to
0.000 . The cube's surface is now showing only the Diffuse component,
because the Diffuse BSDF shader is connected to the first Shader input
socket that is corresponding to a value set to 0.000 .
