00:00:00.06 --> 00:00:01.07

- [Instructor] In this

movie, I'll show you



2

00:00:01.07 --> 00:00:03.04

how to light your 3D object



3

00:00:03.04 --> 00:00:06.01

to achieve an effect

more like this one here



4

00:00:06.01 --> 00:00:09.04

complete with highlights and shading.



5

00:00:09.04 --> 00:00:10.08

All right, so even though we're not seeing



6

00:00:10.08 --> 00:00:13.06

this selection edges,

my notes are selected



7

00:00:13.06 --> 00:00:15.08

and I can verify that by pressing Ctrl + H



8

00:00:15.08 --> 00:00:17.07

or Command + H on the Mac.



9

00:00:17.07 --> 00:00:18.09

So there they are.



10

00:00:18.09 --> 00:00:22.03

I'm going to press Command or

Ctrl + H again to hide them.



11

00:00:22.03 --> 00:00:25.00

Then I'll go ahead and click

on the setting right here



12

00:00:25.00 --> 00:00:27.02

3D Extrude & Bevel.



13

00:00:27.02 --> 00:00:30.05

And by the way, if it bothers

you that this 3D Rotate



14

00:00:30.05 --> 00:00:33.05

is still sitting here, you can

just go ahead and select it



15

00:00:33.05 --> 00:00:35.01

and then click on the trash can icon



16

00:00:35.01 --> 00:00:37.09

down here at the bottom

of the Appearance panel.



17

00:00:37.09 --> 00:00:40.05

All right, now I'll click

on 3D Extrude & Bevel



18

00:00:40.05 --> 00:00:43.02

to bring up this by now

familiar dialogue box



19

00:00:43.02 --> 00:00:45.00

and I'll turn on the Preview check box



20

00:00:45.00 --> 00:00:47.00

so I can see what I'm doing.



21

00:00:47.00 --> 00:00:50.04

Now what you want to do is

click on the More Options button



22

00:00:50.04 --> 00:00:53.04

in order expand the

size of the dialogue box



23

00:00:53.04 --> 00:00:57.05

to include all of these

sliding options down here.



24

00:00:57.05 --> 00:01:01.00

Now notice that we currently

have just one light



25

00:01:01.00 --> 00:01:03.04

that's appearing on the sphere.



26

00:01:03.04 --> 00:01:06.04

And you can move that light

to any location you like.



27

00:01:06.04 --> 00:01:09.08

I'm going to drag it up a

little bit to right about there.



28

00:01:09.08 --> 00:01:11.06

Then I'm going to add another light



29

00:01:11.06 --> 00:01:13.09

by clicking on this little page icon.



30

00:01:13.09 --> 00:01:16.02

And so then you just drag that new light



31

00:01:16.02 --> 00:01:17.08

to a different location.



32

00:01:17.08 --> 00:01:19.05

Now I'm going to add a third one



33

00:01:19.05 --> 00:01:21.05

by once again clicking on the page icon.



34

00:01:21.05 --> 00:01:24.04

I'll go ahead and move

it up to the top here.



35

00:01:24.04 --> 00:01:27.07

I'm going to send it to back of the object



36

00:01:27.07 --> 00:01:31.04

by clicking on this left

hand icon below this sphere



37

00:01:31.04 --> 00:01:33.06

and notice that's going

to give us a little bit



38

00:01:33.06 --> 00:01:36.06

of additional lighting

along the tops of the notes.



39

00:01:36.06 --> 00:01:41.00

Again you can move these guys

to any location you like.



40

00:01:41.00 --> 00:01:42.04

Now I want to direct your attention



41

00:01:42.04 --> 00:01:44.04

to these various numerical options



42

00:01:44.04 --> 00:01:46.04

starting with light intensity.



43

00:01:46.04 --> 00:01:49.05

Now light intensity is the

only option that affects



44

00:01:49.05 --> 00:01:51.08

each light source independently.



45

00:01:51.08 --> 00:01:54.09

All the other options

affect the overall lighting.



46

00:01:54.09 --> 00:01:57.09

For example, if I want

this, like right here,



47

00:01:57.09 --> 00:02:01.08

to be less intense, then I

could select it and reduce



48

00:02:01.08 --> 00:02:05.08

the light intensity value

down to 30% let's say



49

00:02:05.08 --> 00:02:08.06

which is going to dim down

the front of the objects.



50

00:02:08.06 --> 00:02:10.02

Now I don't really want that



51

00:02:10.02 --> 00:02:12.06

so I'm going to change it back to 100%.



52

00:02:12.06 --> 00:02:15.08

Notice that I'm not seeing

any change on screen



53

00:02:15.08 --> 00:02:17.04

out here on the document window,



54

00:02:17.04 --> 00:02:21.02

In fact, if I were to switch

to this light source right here



55

00:02:21.02 --> 00:02:23.01

whose light intensity is 100%,



56

00:02:23.01 --> 00:02:25.04

then switch back to the one I modified,



57

00:02:25.04 --> 00:02:28.08

you can see that my

adjustment didn't take.



58

00:02:28.08 --> 00:02:30.05

If you have that problem,

then just go ahead



59

00:02:30.05 --> 00:02:32.03

and select the offending light source



60

00:02:32.03 --> 00:02:35.02

and click on the little trash

can icon to get rid of it



61

00:02:35.02 --> 00:02:37.01

and then just add a new one.



62

00:02:37.01 --> 00:02:38.07

By clicking on the page icon, once again,



63

00:02:38.07 --> 00:02:41.04

it will automatically come in

with the light intensity value



64

00:02:41.04 --> 00:02:44.07

of 100% at which point we

can then move these guys



65

00:02:44.07 --> 00:02:46.03

at different locations.



66

00:02:46.03 --> 00:02:50.00

Now you're not going to have

a lot of precision control



67

00:02:50.00 --> 00:02:52.05

where the positions of

the lights are concerned



68

00:02:52.05 --> 00:02:55.04

because we're working

with this tiny preview.



69

00:02:55.04 --> 00:02:56.08

So you're just going

to have to do your best



70

00:02:56.08 --> 00:02:58.03

where that's concerned.



71

00:02:58.03 --> 00:03:00.03

All right, now we've got ambient light



72

00:03:00.03 --> 00:03:02.09

and that's going to control

how much general sunlight



73

00:03:02.09 --> 00:03:04.08

is available to the scene.



74

00:03:04.08 --> 00:03:06.01

Notice if you take this value up,



75

00:03:06.01 --> 00:03:08.08

you really going to flat on the lighting



76

00:03:08.08 --> 00:03:11.02

and it might be it doesn't

really tend to look that great



77

00:03:11.02 --> 00:03:13.04

which is why I typically

take the ambient light



78

00:03:13.04 --> 00:03:15.00

down to zero percent



79

00:03:15.00 --> 00:03:18.00

so we have this much contrast as possible.



80

00:03:18.00 --> 00:03:20.08

You can also control the

intensity of the highlights



81

00:03:20.08 --> 00:03:23.00

to make them very bright indeed



82

00:03:23.00 --> 00:03:24.07

as we're seeing at a hundred percent



83

00:03:24.07 --> 00:03:28.04

or to dim them down

like so at zero percent.



84

00:03:28.04 --> 00:03:30.00

Now again, I want a lot of contrast



85

00:03:30.00 --> 00:03:32.06

so I'm going to create

that guy up to its maximum.



86

00:03:32.06 --> 00:03:34.05

Then we've got highlight size



87

00:03:34.05 --> 00:03:37.00

so you can either have very big highlights



88

00:03:37.00 --> 00:03:38.09

as we're seeing here at a 100%



89

00:03:38.09 --> 00:03:41.02

or you can reduce the size



90

00:03:41.02 --> 00:03:43.04

of the highlights at smaller values.



91

00:03:43.04 --> 00:03:46.04

I'm going to take this value

to 50% this time around.



92

00:03:46.04 --> 00:03:49.00

Finally we have Blend Steps.



93

00:03:49.00 --> 00:03:52.05

What illustrators are doing

is creating blends on the fly.



94

00:03:52.05 --> 00:03:56.04

So notice if I take that

steps value down to five,



95

00:03:56.04 --> 00:03:58.07

we get a ton of bending.



96

00:03:58.07 --> 00:04:01.04

So what you want to do is

click inside that value



97

00:04:01.04 --> 00:04:05.03

and press Shift + Up Arrow

until the bending goes away.



98

00:04:05.03 --> 00:04:08.02

Now the value of 30 steps,

things look pretty good



99

00:04:08.02 --> 00:04:10.09

but if you want the image

to be smoother still,



100

00:04:10.09 --> 00:04:14.05

then you might want to take

it as high as, say 150,



101

00:04:14.05 --> 00:04:16.09

bearing in mind that more

steps is going to potentially



102

00:04:16.09 --> 00:04:19.06

slow down illustrators performance.



103

00:04:19.06 --> 00:04:21.08

You can also control the shading color



104

00:04:21.08 --> 00:04:23.05

which by default is black



105

00:04:23.05 --> 00:04:25.01

but if you want to use a different color,



106

00:04:25.01 --> 00:04:26.08

then you can select Custom



107

00:04:26.08 --> 00:04:28.08

and then click on the little color Swatch



108

00:04:28.08 --> 00:04:31.00

and dial in something different



109

00:04:31.00 --> 00:04:33.02

presumably not red of course



110

00:04:33.02 --> 00:04:35.07

but maybe a dark shade of purple.



111

00:04:35.07 --> 00:04:38.09

At which point I'll click OK

in order to apply that change.



112

00:04:38.09 --> 00:04:40.01

That is an option.



113

00:04:40.01 --> 00:04:43.07

In my case however, I'm

going to stick with black.



114

00:04:43.07 --> 00:04:45.07

All right, now I want

to show you how you have



115

00:04:45.07 --> 00:04:47.07

four different surface settings.



116

00:04:47.07 --> 00:04:50.01

So notice if I switch to wire frame,



117

00:04:50.01 --> 00:04:52.05

I lose all those numerical options



118

00:04:52.05 --> 00:04:55.06

and I'm just seeing a wire

frame preview out here



119

00:04:55.06 --> 00:04:57.01

in the document window.



120

00:04:57.01 --> 00:04:59.03

You also have the option of no shading



121

00:04:59.03 --> 00:05:01.09

which is going to go ahead

and fill in the object



122

00:05:01.09 --> 00:05:04.05

but you're not going to have

any highlights or shadows.



123

00:05:04.05 --> 00:05:06.06

Not sure if you're ever going

to follow these for that



124

00:05:06.06 --> 00:05:08.00

but there it is.



125

00:05:08.00 --> 00:05:10.06

The third option is the Diffuse Shading



126

00:05:10.06 --> 00:05:12.08

which is going to give you darker colors



127

00:05:12.08 --> 00:05:14.08

than the specified fills.



128

00:05:14.08 --> 00:05:17.03

So notice my fill is set

to the shaded purple.



129

00:05:17.03 --> 00:05:19.00

We are seeing shading



130

00:05:19.00 --> 00:05:21.09

but we're not seeing anything

brighter than the color



131

00:05:21.09 --> 00:05:24.03

and we lose the two highlight values.



132

00:05:24.03 --> 00:05:27.01

Finally, if you want both

shading and highlights,



133

00:05:27.01 --> 00:05:29.04

you want to switch to plastic shading



134

00:05:29.04 --> 00:05:31.07

which is the default setting.



135

00:05:31.07 --> 00:05:33.05

And which why I'll go ahead and click OK



136

00:05:33.05 --> 00:05:36.03

to accept those changes.



137

00:05:36.03 --> 00:05:39.06

That's how you light your

objects here inside illustrator.



138

00:05:39.06 --> 00:05:40.06

In the next movie,



139

00:05:40.06 --> 00:05:43.03

I'll show you how to create beveled edges.
