Creating an expanded polystyrene material
In this recipe, we will create a classic white expanded polystyrene material, as shown in
this screenshot:

Getting ready...
First, let's prepare the scene:
1.
Start Blender and load the
9931OS_Suzanne_start.blend
file. Add a Cube
primitive to the scene and place it leaning on the Plane, close to Suzanne. Move
it upwards by 1 Blender unit.
2.
With the mouse arrow in the Camera view, press
Shift
+
F
to enter Walk Mode
(in this mode, you can press the
W
key to go forward, press
S
to go back, move
the mouse to decide the direction, and click or press
Enter
to confirm). Adjust
the Camera position so as to center the two objects in the frame.
3.
Select the Cube object and go to the Object modifiers window. Assign a
Boolean modifier.
4.
Press
Shift
+
D
to duplicate the Cube, and move it a bit upward (press
G
, then
press
Z
, enter
.4
, and press
Enter
). Reselect the first Cube, and in the Object field
of the Boolean modifier panel, select the second Cube (Cube.001). Set Operation
to Difference. Go to Edit Mode and scale all the vertices a bit larger on the
x
and
y
axes (press
S
, then press
Shift
+
Z
, enter
1.200
, and press
Enter
).
5.
Exit Edit Mode and reselect Cube.001. Move it a bit on the
x
axis (press
G
, then
press
X
, enter
.4
, and press
Enter
).
6.
Go to the Object window and set Maximum Draw Type to Wire. Then go to the
Ray Visibility subpanel (usually at the bottom) and uncheck all the items. This way,
Cube.001 becomes visible in the 3D view, but is not yet rendered in the preview.
7.
Just to be sure that the second cube is not visible (the previous step should be
enough for the final rendering), go to Outliner and click on the camera icon to
the right of the Cube.001 item.
