From step 8 to step 18, we built the HULL frame group by superimposing two
differently scaled versions of the same image. Then they could be used for the color,
bump, and specular components. These components were obtained by contrasting
the paneling through a ColorRamp node and then going straight to the Glossy BSDF
shader's roughness and the Anisotropic BSDF shader, to add a metallic look. The
mixture of both Glossy BSDF and Anisotropic BSDF is made on the ground of a
Fresnel node set to
100.000
. A very high value like this is needed because the
specularity is then mixed again with the Diffuse BSDF component to the purpose
to obtain a slider to tweak the effect.
F
From step 19 to step 24, we added the red hull's logo, ARGUS, using its own
alpha channel to overimpose it on the hull surface's panels..
F
From step 25 to step 30, we built the WINDOWS frame group.
F
In step 31, we merged (averaged) the bump effect of the windows with the
bump effect of the hull's panels.
F
From step 32 to step 38, we made the masking for the windows to give them
a random appearance.
F
From step 39 to step 41, we simply connected the various frames' output.
F
From step 42 to step 44, we created the light-emitting material for the windows.
Note that the WINDOWS_ MASK frame group provides the masking for the windows'
positions. The WINDOW frame group provides the whiteness values for the windows,
the bump, and the last nodes added to the SHADER frame the light emission based
on the output of the previous frame groups.

The appearance of the hull can be improved even further using some displacement to add
geometric details to the spaceship surface, which (at the moment) is a bit too smooth:
1.
Go to the Object modifiers window and assign a second Subdivision Surface
modifier to Torus. Set the Subdivisions levels to
2
for both View and Render.
2.
Assign a Displace modifier. Then click on the Show texture in texture tab button
on the right side of the Texture slot. In the Textures window, click on the New button.
Then replace the default Clouds texture with an Image or Movie texture.
