Creating a Gray Alien skin material with
procedurals
In this recipe, we will create a Gray Alien-like skin shader using Cycles procedural
textures, as shown here:
Getting ready
Start Blender and open the
1301OS_07_alienskin_start.blend
file, where
there is an already set scene with an unwrapped
Suzanne
primitive object. The
Suz-
anne
mesh has been "alienizated" by a shape key to morph its monkey-like features
into the head of a Gray Alien-like creature (in the
Object Data
window, under the
Shape Keys
tab, the
alien
shape keys with a
Value
of
1.000
, and sliding the slider
towards
0.000
gradually restore the original
Suzanne
shape).
On the second layer, there is a plane tracked (by a
Damped Track
constraint, in the
Object Constraints
window) to the
Camera
to stay perpendicular to the point of view,
which we'll use to create a simple star backdrop for our alien
Suzanne
.
How to do it...
Let's start by setting the background image material first:
1. Select the background plane and click on the
New
button in the
Node Ed-
itor
window's header or in the
Material
window. Rename the material as
star_backdrop
and in the
Material
window switch the
Diffuse BSDF
shader with an
Emission
shader. Set the
Strength
value to
0.500
.
2. Add an
Image Texture
node (press
Shift
+
A
and go to
Texture
|
Image
Texture
) and connect the
Color
output to the
Color
input socket of the
Emission
node. Click on the
Open
button and browse to the
textures
