1
00:00:00.06 --> 00:00:02.01
- [Voiceover] In this movie I'll show you

2
00:00:02.01 --> 00:00:03.07
how to introduce some texture into your

3
00:00:03.07 --> 00:00:06.02
custom gradient, using dynamic effects.

4
00:00:06.02 --> 00:00:08.06
Specifically, we'll be
going for this grass texture

5
00:00:08.06 --> 00:00:11.05
right here, but there's all
kinds of stuff you could do.

6
00:00:11.05 --> 00:00:13.06
Alright, so I'll go ahead
and switch over to my

7
00:00:13.06 --> 00:00:17.01
pre texture file and I'll
click on those rolling hills

8
00:00:17.01 --> 00:00:20.04
with the black arrow tool, in
order to select that blend.

9
00:00:20.04 --> 00:00:22.07
You know it's a blend because
it's identified as such

10
00:00:22.07 --> 00:00:25.03
in the far left side of the control panel.

11
00:00:25.03 --> 00:00:27.06
Alright, so lets say you
want the hills to bob up

12
00:00:27.06 --> 00:00:29.03
and down a little more aggressively.

13
00:00:29.03 --> 00:00:32.01
The first thing I'll do is
press Ctrl + H or Command + H

14
00:00:32.01 --> 00:00:34.02
on the Mac in order to
hide my anchor points.

15
00:00:34.02 --> 00:00:37.01
In that way we can just see
things better on screen.

16
00:00:37.01 --> 00:00:39.09
And then, I'll go up to
the Effect menu, choose

17
00:00:39.09 --> 00:00:43.05
Distort and Transform, and
let's start with Tweak.

18
00:00:43.05 --> 00:00:45.09
I'll go ahead and choose
that command and then I'll

19
00:00:45.09 --> 00:00:48.00
turn on the preview
checkbox so you can see how

20
00:00:48.00 --> 00:00:50.08
things are buffeting up
and down in the background.

21
00:00:50.08 --> 00:00:53.09
I'm gonna go ahead and switch
from relative to absolute.

22
00:00:53.09 --> 00:00:56.02
And I'll take the
horizontal line down to zero

23
00:00:56.02 --> 00:00:58.07
because we really don't need
things moving back and forth.

24
00:00:58.07 --> 00:01:01.05
We need the gradient
intervals to move up and down.

25
00:01:01.05 --> 00:01:03.01
And we can do that by raising

26
00:01:03.01 --> 00:01:04.08
this vertical value right here.

27
00:01:04.08 --> 00:01:08.01
And I'm pressing shift + up
arrow in order to increase

28
00:01:08.01 --> 00:01:10.05
the value in increments of 10 points.

29
00:01:10.05 --> 00:01:13.01
And as you can see at 60 points we get

30
00:01:13.01 --> 00:01:15.01
a whole lot of action going on.

31
00:01:15.01 --> 00:01:17.06
It pretty much ruins
any smooth color effect

32
00:01:17.06 --> 00:01:19.02
we might have had previously.

33
00:01:19.02 --> 00:01:22.08
But, it gives us a lot of extra
action in those intervals.

34
00:01:22.08 --> 00:01:24.08
You also have the option of deciding

35
00:01:24.08 --> 00:01:26.01
what it is your modifying.

36
00:01:26.01 --> 00:01:28.07
Anchor points controls the
placement of anchor points,

37
00:01:28.07 --> 00:01:32.05
so if you turn that off,
you're just going to move

38
00:01:32.05 --> 00:01:34.09
the so called control points here.

39
00:01:34.09 --> 00:01:37.05
Those are really the
control handles however.

40
00:01:37.05 --> 00:01:40.02
And you can even decide
well I actually just want to

41
00:01:40.02 --> 00:01:42.08
move the handles that are
going out of the points,

42
00:01:42.08 --> 00:01:44.07
not the ones that are going in.

43
00:01:44.07 --> 00:01:48.02
Or you can try the
opposite effect like so.

44
00:01:48.02 --> 00:01:49.09
And each time you're
going to get something

45
00:01:49.09 --> 00:01:50.09
different out of it.

46
00:01:50.09 --> 00:01:53.04
So it really depends if
you want gentle rolling,

47
00:01:53.04 --> 00:01:56.00
in which case you want to
modify the control handles

48
00:01:56.00 --> 00:01:59.03
and not the anchor points,
or if you want a bunch

49
00:01:59.03 --> 00:02:02.03
spikey action, in which
case you want to modify

50
00:02:02.03 --> 00:02:04.03
the anchor points and possibly

51
00:02:04.03 --> 00:02:05.08
leave the control handles alone.

52
00:02:05.08 --> 00:02:08.09
Alright, so doing this for
the sake of demonstration,

53
00:02:08.09 --> 00:02:10.00
I'm going to cancel out here.

54
00:02:10.00 --> 00:02:12.07
And now let's say we want a wavy effect.

55
00:02:12.07 --> 00:02:15.05
So for example, imagine that
instead of editing grass

56
00:02:15.05 --> 00:02:17.05
this were supposed to water.

57
00:02:17.05 --> 00:02:19.08
In that case, you would
go up to the Effect menu

58
00:02:19.08 --> 00:02:23.07
and choose Distort and Transform
and choose Zig Zag instead.

59
00:02:23.07 --> 00:02:26.00
And now I'll go ahead and
turn on the preview checkbox.

60
00:02:26.00 --> 00:02:29.03
And you can see a bunch of
spikes going on in the background

61
00:02:29.03 --> 00:02:31.08
and you can increase the
size of those spikes by

62
00:02:31.08 --> 00:02:35.03
switching from relative to
absolute if indeed relative

63
00:02:35.03 --> 00:02:37.06
is selected for you in the
first place, and then we

64
00:02:37.06 --> 00:02:39.09
can increase that size value
to something like 20 points.

65
00:02:39.09 --> 00:02:41.09
And notice we're getting all kinds

66
00:02:41.09 --> 00:02:43.05
of additional spiking going on.

67
00:02:43.05 --> 00:02:45.07
If you want these to be more gentle waves,

68
00:02:45.07 --> 00:02:48.09
then switch your points from
corner to smooth like so,

69
00:02:48.09 --> 00:02:51.00
and you'll get more of a rippling effect.

70
00:02:51.00 --> 00:02:54.00
And if you want soften things
down a little bit further,

71
00:02:54.00 --> 00:02:57.00
then decrease this
ridges per segment value.

72
00:02:57.00 --> 00:02:59.08
And I'm gonna take it down
to either one or I think two.

73
00:02:59.08 --> 00:03:01.02
I think two ends up looking better.

74
00:03:01.02 --> 00:03:04.06
And then I might take that
size value back down to 10.

75
00:03:04.06 --> 00:03:06.09
And so you have all
sorts of options there.

76
00:03:06.09 --> 00:03:09.01
I'll go ahead and click
okay to apply this option.

77
00:03:09.01 --> 00:03:11.07
And then I'll show you what
happens if we follow this up.

78
00:03:11.07 --> 00:03:13.00
By going to the Object menu,

79
00:03:13.00 --> 00:03:16.08
choosing Blend and then
choosing Blend Options.

80
00:03:16.08 --> 00:03:19.05
And lets switch spacing
to specified steps, turn

81
00:03:19.05 --> 00:03:21.08
on the preview checkbox
and then take this value

82
00:03:21.08 --> 00:03:24.01
down to something like 10,

83
00:03:24.01 --> 00:03:26.06
or I might even take it down to five

84
00:03:26.06 --> 00:03:28.06
just so we can really see what's going on.

85
00:03:28.06 --> 00:03:31.03
And now notice the rolling
action that is associated

86
00:03:31.03 --> 00:03:33.01
with each one of these intervals.

87
00:03:33.01 --> 00:03:35.01
Alright, I'm gonna go
ahead and cancel out.

88
00:03:35.01 --> 00:03:37.09
And also press Ctrl + Z
or Command + Z on the Mac

89
00:03:37.09 --> 00:03:40.05
a couple of times apparently in order

90
00:03:40.05 --> 00:03:42.00
to undo that zig zag effect.

91
00:03:42.00 --> 00:03:45.06
For a grassy effect what
we need to do is return

92
00:03:45.06 --> 00:03:46.07
to the Effect menu,

93
00:03:46.07 --> 00:03:49.02
choose Distort and Transform
and choose Roughen.

94
00:03:49.02 --> 00:03:51.08
And now I'll go ahead and
turn on the preview checkbox

95
00:03:51.08 --> 00:03:53.05
so that you can see that we have a ton

96
00:03:53.05 --> 00:03:56.01
of very rough intervals indeed.

97
00:03:56.01 --> 00:03:58.09
Alright, I'm gonna switch
from relative to absolute

98
00:03:58.09 --> 00:04:01.03
to start things out here
and I'm gonna leave the size

99
00:04:01.03 --> 00:04:02.07
value set to five points.

100
00:04:02.07 --> 00:04:06.00
That's the size of each one
of these ripples by the way.

101
00:04:06.00 --> 00:04:07.06
So if you wanted more spikeyness

102
00:04:07.06 --> 00:04:09.03
you would increase that value.

103
00:04:09.03 --> 00:04:12.01
But a size of five is going to
work fine for this document.

104
00:04:12.01 --> 00:04:15.00
And then I'll tab over to
the detail value and take

105
00:04:15.00 --> 00:04:17.01
it up to 30 per inches.

106
00:04:17.01 --> 00:04:19.08
So in other words, 30
blades of grass per inch.

107
00:04:19.08 --> 00:04:23.01
And if you wanted things to
be smoother, that is to say

108
00:04:23.01 --> 00:04:25.00
you want to use smooth points
instead of corner points,

109
00:04:25.00 --> 00:04:26.04
you could go ahead and switch this

110
00:04:26.04 --> 00:04:28.02
points option if you want to.

111
00:04:28.02 --> 00:04:31.01
But I want the spikier action
associated with corner points,

112
00:04:31.01 --> 00:04:35.07
so I'll leave this option set
to its default and click ok.

113
00:04:35.07 --> 00:04:37.07
Now I'll just go ahead
and zoom in a little bit,

114
00:04:37.07 --> 00:04:39.06
so we can see things a little better.

115
00:04:39.06 --> 00:04:42.04
You can undoubtedly see these
spikes up here at the top.

116
00:04:42.04 --> 00:04:44.05
But if you're working along
with me you should be able

117
00:04:44.05 --> 00:04:46.07
to see some action inside
the gradient as well.

118
00:04:46.07 --> 00:04:48.09
To make the grass effect
a little more obvious,

119
00:04:48.09 --> 00:04:51.06
go to the Object menu, choose Blend,

120
00:04:51.06 --> 00:04:53.07
and then choose Blend Options

121
00:04:53.07 --> 00:04:56.08
and then switch the spacing
options to Specified Steps

122
00:04:56.08 --> 00:05:00.07
and take this value all
the way down to five

123
00:05:00.07 --> 00:05:02.05
and turn on the preview checkbox.

124
00:05:02.05 --> 00:05:04.09
And now you can see an awful lot of

125
00:05:04.09 --> 00:05:08.04
cartoon grass action inside this document.

126
00:05:08.04 --> 00:05:10.01
In which point, I'll go ahead and click OK

127
00:05:10.01 --> 00:05:11.07
to accept that effect.

128
00:05:11.07 --> 00:05:14.03
And of course because you're
working with a dynamic effect,

129
00:05:14.03 --> 00:05:16.09
you can revisit your
settings anytime you like by

130
00:05:16.09 --> 00:05:19.08
going to the Window menu
and choosing the Appearance

131
00:05:19.08 --> 00:05:22.02
command and then here
inside the appearance panel,

132
00:05:22.02 --> 00:05:23.09
just go ahead and click the word Roughen.

133
00:05:23.09 --> 00:05:26.08
Turn on the preview checkbox
and then for example and take

134
00:05:26.08 --> 00:05:29.08
this detail value up to
60 per inch, at which

135
00:05:29.08 --> 00:05:33.02
point we'll see even more blades of grass.

136
00:05:33.02 --> 00:05:35.01
I'm pretty happy with 30 however.

137
00:05:35.01 --> 00:05:37.00
So I'm just gonna go ahead and cancel out.

138
00:05:37.00 --> 00:05:40.00
And then you might want to
press Ctrl + H or Command + H

139
00:05:40.00 --> 00:05:43.00
on a Mac in order to bring
back those selection outlines

140
00:05:43.00 --> 00:05:45.03
because after all whether
they're visible or not

141
00:05:45.03 --> 00:05:47.08
is saved along with the illustration.

142
00:05:47.08 --> 00:05:50.03
And then finally I'll go
ahead and zoom out by pressing

143
00:05:50.03 --> 00:05:53.06
Ctrl + zero and I'll
press Ctrl + Shift + A or

144
00:05:53.06 --> 00:05:54.07
Command + Shift + A on a Mac in order

145
00:05:54.07 --> 00:05:56.05
to deselect the artwork.

146
00:05:56.05 --> 00:05:59.02
And that's how you add text
to your custom gradient.

147
00:05:59.02 --> 00:06:01.03
By going to the Effect menu and choosing

148
00:06:01.03 --> 00:06:03.09
Distort and Transform
and then experimenting

149
00:06:03.09 --> 00:06:05.07
with either Tweak, Zig Zag

150
00:06:05.07 --> 00:06:08.06
or Roughen here inside Illustrator.
