The
Eyes Have It
[Page 4 of 7]
The 'Inner'
object
The "Inner" object is the white of your eye and the
one to which we will be applying the veins texture map.
1 . As with
the "Innerinner" object, we're first going to do a little
shape changing. So switch over to FX mode, select the Flatten
effect and create a depression whose diameter is about 1/3 the
total diameter of the visible area of the "Inner" object,
just as you did with the "Innerinner" object..
2. Switch
to the Material mode.
2a. For
Diffuse color and Specular Color, choose White, and leave the
setting at 100 percent. (If you'd like to add veins to your
eyeball, this would be the place to do it, choosing a veins
texture map for the Diffuse Color, and a veins bump map for
Specular and Bump.)
2b. Set
your Specular Roughness to something like 10.
2c. Set
your Transparency to 10 percent. A higher number creates more
transparency; a lower number will make the object more opaque.
This setting will determine how much of the blue "Innerinner"
object you'll be able to see in the final render.
2d. Keep
your refraction low, not exceeding 1.090. I have mine set at
1.090, which might even be a bit too high, since the actual
white of the eye doesn't do much refracting.
2e. Set
your Reflectivity below 30. (I have mine at 10.)
All done with
the "Inner" object. Time to move on to the "Outer."
The 'Outer'
object
The "Outer" object is the clear goo on the outside of
your eye, including the lens of the eye. Unlike the previous two
objects, this one will not be tweaked in the FX workspace. Rather,
we're going to use our Tools mode to pull out a rounded bulge
on the front of our eye to represent the lens.
1. Go into
Tool mode and choose "Outer" from the Choose menu at
the bottom of your screen. You're going to use the Brush tool,
but we're going to have to set both the radius and the direction
of the brush. In the Brush palette, make sure the direction arrow
is pointing left. Set the Radius to something like a third the
diameter of the object.
With the
Direction arrow pointing
left, the Brush tool pulls out
on your geometry rather
than pushing in.
2. Slowly
apply the tool until you have a small protrusion. It would be
best to use a pressure tablet, but you can also just turn down
the default pressure in the Brush palette.
