Before you can start on modeling the eye you are going to create a Sphere
which will act as the eyeball and thus make modeling the shapes of the eyelids
easier. There is also a tutorial that deals with the making of an eyeball. You can
jump to that part first if you want, but here you are going to use a simple Sphere.
Create a Sphere (Objects=>Primitives=>Sphere). The default Sphere has to be
adjusted first. Double click on its icon in the Object Manager and change the
radius to 13.35m and click OK. Double click on the name of the Sphere and
rename it 'Eyeball'. With the Eyeball still selected in the Object Manager go to
the Coordinates Manager and change the Position to X=29.5m, Y=22m, and Z=-
58m. You need the Eyeball to be transparent when modeling around it. What
you need to do is create a transparent material and apply it to the Eyeball. In the
Material Manager create a New Material (File=>New Material). Double click on
its icon and in the Material dialog change the Color setting to a yellow color by
dragging the B (Blue) slider to 0%. Check the Transparency channel's setting,
and set the Brightness to 4%. Check the Fog channel, change the Color setting
to a yellow color by dragging the B slider to 0%. As the last change, uncheck the
Specular channel. Close the Material dialog. Apply the texture to the Eyeball by
dragging it over the eyeball in the Object Manager. Accept the default settings
from the Texture dialog and click OK.
