In this recipe, we will create a gray alien-like skin shader as shown in the following screenshot, using Cycles procedural textures:
Start Blender and open the 9931OS_08_alienskin_start.blend
file, where there is an already set scene with an unwrapped Suzanne primitive object.
The
Suzanne_unwrapped_alien mesh has been modified by a shape key, to morph its monkey features into the head of a gray alien–like creature; in fact, in the Object data window, under the Shape Keys subpanel, there are the alien shape keys, with Value of 1.000
; sliding the slider towards 0.000
gradually restores the original Suzanne shape.
The Suzanne mesh also has a Vertex Colors layer named Col and is obtained by the Dirty Vertex Colors tool.
On the second layer, there are two Planes tracked (by a Damped Track constraint, in the Object Constraints window) to the Camera to stay perpendicular to its point...
