Creating a snake-like scaly material
with image maps and procedurals
In this recipe we will create a snake-like scaly skin material, as shown here:
Getting ready
Start Blender and open the 1301OS_07_start.blend file, where there is an
already set scene with an unwrapped Suzanne primitive object.
How to do it...
Let's go straight to the material creation:
1. Click on New in the Node Editor window's header or in the Material win-
dow on the right and rename the new material as scales .
2. Press Tab to go in the edit mode and select the eyes' vertexes (put the
mouse pointer on the part and press the L key to select all the connected
vertexes). Click on the + icon in the top-left corner of the Material window
to add a new material. Click on New , rename the material as eyes , and
click on the Assign button. Press Tab to come out of the edit mode.
3. In the Material window, switch the Diffuse shader with a Mix Shader
node. In the first Shader slot, select a Diffuse BSDF node and in the
second one, a Glossy BSDF shader node.
4. Set the Diffuse shader's Color value to a yellowish hue ( R 0.800 , G 0.655 ,
B 0.105 ) and the Glossy shader's Color value to pure white. Set the
Glossy shader's Roughness value to 0.200 .
5. Now, in the Material window, select the scales material. Switch the Dif-
fuse shader with a Mix Shader node. In the first Shader slot, select a Dif-
fuse BSDF shader node and in the second one, a Glossy BSDF shader
