- [Instructor] In this movie, I'll show you
how to light your 3D object
to achieve an effect more like this one here
complete with highlights and shading.
All right, so even though we're not seeing
this selection edges, my notes are selected
and I can verify that by pressing Ctrl + H
or Command + H on the Mac.
So there they are.
I'm going to press Command or Ctrl + H again to hide them.
Then I'll go ahead and click on the setting right here
3D Extrude & Bevel.
And by the way, if it bothers you that this 3D Rotate
is still sitting here, you can just go ahead and select it
and then click on the trash can icon
down here at the bottom of the Appearance panel.
All right, now I'll click on 3D Extrude & Bevel
to bring up this by now familiar dialogue box
and I'll turn on the Preview check box
so I can see what I'm doing.
Now what you want to do is click on the More Options button
in order expand the size of the dialogue box
to include all of these sliding options down here.
Now notice that we currently have just one light
that's appearing on the sphere.
And you can move that light to any location you like.
I'm going to drag it up a little bit to right about there.
Then I'm going to add another light
by clicking on this little page icon.
And so then you just drag that new light
to a different location.
Now I'm going to add a third one
by once again clicking on the page icon.
I'll go ahead and move it up to the top here.
I'm going to send it to back of the object
by clicking on this left hand icon below this sphere
and notice that's going to give us a little bit
of additional lighting along the tops of the notes.
Again you can move these guys to any location you like.
Now I want to direct your attention
to these various numerical options
starting with light intensity.
Now light intensity is the only option that affects
each light source independently.
All the other options affect the overall lighting.
For example, if I want this, like right here,
to be less intense, then I could select it and reduce
the light intensity value down to 30% let's say
which is going to dim down the front of the objects.
Now I don't really want that
so I'm going to change it back to 100%.
Notice that I'm not seeing any change on screen
out here on the document window,
In fact, if I were to switch to this light source right here
whose light intensity is 100%,
then switch back to the one I modified,
you can see that my adjustment didn't take.
If you have that problem, then just go ahead
and select the offending light source
and click on the little trash can icon to get rid of it
and then just add a new one.
By clicking on the page icon, once again,
it will automatically come in with the light intensity value
of 100% at which point we can then move these guys
at different locations.
Now you're not going to have a lot of precision control
where the positions of the lights are concerned
because we're working with this tiny preview.
So you're just going to have to do your best
where that's concerned.
All right, now we've got ambient light
and that's going to control how much general sunlight
is available to the scene.
Notice if you take this value up,
you really going to flat on the lighting
and it might be it doesn't really tend to look that great
which is why I typically take the ambient light
down to zero percent
so we have this much contrast as possible.
You can also control the intensity of the highlights
to make them very bright indeed
as we're seeing at a hundred percent
or to dim them down like so at zero percent.
Now again, I want a lot of contrast
so I'm going to create that guy up to its maximum.
Then we've got highlight size
so you can either have very big highlights
as we're seeing here at a 100%
or you can reduce the size
of the highlights at smaller values.
I'm going to take this value to 50% this time around.
Finally we have Blend Steps.
What illustrators are doing is creating blends on the fly.
So notice if I take that steps value down to five,
we get a ton of bending.
So what you want to do is click inside that value
and press Shift + Up Arrow until the bending goes away.
Now the value of 30 steps, things look pretty good
but if you want the image to be smoother still,
then you might want to take it as high as, say 150,
bearing in mind that more steps is going to potentially
slow down illustrators performance.
You can also control the shading color
which by default is black
but if you want to use a different color,
then you can select Custom
and then click on the little color Swatch
and dial in something different
presumably not red of course
but maybe a dark shade of purple.
At which point I'll click OK in order to apply that change.
That is an option.
In my case however, I'm going to stick with black.
All right, now I want to show you how you have
four different surface settings.
So notice if I switch to wire frame,
I lose all those numerical options
and I'm just seeing a wire frame preview out here
in the document window.
You also have the option of no shading
which is going to go ahead and fill in the object
but you're not going to have any highlights or shadows.
Not sure if you're ever going to follow these for that
but there it is.
The third option is the Diffuse Shading
which is going to give you darker colors
than the specified fills.
So notice my fill is set to the shaded purple.
We are seeing shading
but we're not seeing anything brighter than the color
and we lose the two highlight values.
Finally, if you want both shading and highlights,
you want to switch to plastic shading
which is the default setting.
And which why I'll go ahead and click OK
to accept those changes.
That's how you light your objects here inside illustrator.
In the next movie,
I'll show you how to create beveled edges.
