00:00:00.010 --> 00:00:01.240
Good day, everybody.

2
00:00:01.240 --> 00:00:04.320
In this video, I'm going to go over the Cloud lattice rig type

3
00:00:04.320 --> 00:00:06.560
and how you can use that to create

4
00:00:06.560 --> 00:00:08.720
lattice-based controls for your rigs.

5
00:00:08.720 --> 00:00:11.320
So if you don't know what a lattice-based control is,

6
00:00:11.320 --> 00:00:13.640
I want to show you this lattice setup

7
00:00:13.640 --> 00:00:16.640
that we have on our main Spite Flight character, Ali.

8
00:00:16.640 --> 00:00:19.020
First things first, let me just isolate these two controls

9
00:00:19.020 --> 00:00:20.920
because these are the most important things

10
00:00:20.920 --> 00:00:22.280
that I want to show you.

11
00:00:22.280 --> 00:00:25.080
And if I move this cube, you see that nothing happens,

12
00:00:25.080 --> 00:00:26.960
which is actually a really good thing, as you'll

13
00:00:26.960 --> 00:00:29.640
see in a minute, because when I move this sphere,

14
00:00:29.640 --> 00:00:31.880
it will actually deform the mesh.

15
00:00:31.880 --> 00:00:33.360
So why is that interesting?

16
00:00:33.360 --> 00:00:36.240
Any old armature deformation bone can do that.

17
00:00:36.240 --> 00:00:38.240
However, if I move the cube now, you

18
00:00:38.240 --> 00:00:41.560
can see that this deformation sort of slides along

19
00:00:41.560 --> 00:00:44.360
the surface wherever I put it.

20
00:00:44.360 --> 00:00:46.800
So I can even move this to her forehead.

21
00:00:46.800 --> 00:00:49.000
It's not strictly a cheek control,

22
00:00:49.000 --> 00:00:51.560
even though it is called that way.

23
00:00:51.560 --> 00:00:53.360
But technically speaking, the animator

24
00:00:53.360 --> 00:00:55.600
can use this for whatever they want.

25
00:00:55.600 --> 00:01:00.320
And all this needs to function is a lattice object, which

26
00:01:00.320 --> 00:01:03.560
is this one, which is very hard to make out

27
00:01:03.560 --> 00:01:05.880
what the hell is happening because it's a giant mess.

28
00:01:05.880 --> 00:01:08.060
But the good news is you actually pretty much

29
00:01:08.060 --> 00:01:10.480
don't need to worry about this at all because Cloud Rig is

30
00:01:10.480 --> 00:01:12.760
going to create this object for you.

31
00:01:12.760 --> 00:01:14.160
So I can just hide that.

32
00:01:14.160 --> 00:01:16.200
And the other thing that will be needed

33
00:01:16.200 --> 00:01:20.560
is a lattice modifier, which I think in our case is this one.

34
00:01:20.560 --> 00:01:24.520
So this lattice modifier is on Ali's face mesh,

35
00:01:24.520 --> 00:01:27.360
and it targets that lattice object that I just showed you.

36
00:01:27.360 --> 00:01:28.960
And this lattice modifier will actually

37
00:01:28.960 --> 00:01:31.880
need to be created by you, the rigger.

38
00:01:31.880 --> 00:01:34.160
This does not get automatically created by Cloud Rig,

39
00:01:34.160 --> 00:01:36.000
but I will show you how to set this up.

40
00:01:36.000 --> 00:01:39.200
So I think because I don't want to use this as an example

41
00:01:39.200 --> 00:01:41.280
because I think it would be quite confusing with all

42
00:01:41.280 --> 00:01:42.820
this other stuff going on, I'm going

43
00:01:42.820 --> 00:01:46.000
to head over to a simpler file and show you guys how this

44
00:01:46.000 --> 00:01:46.480
works.

45
00:01:46.480 --> 00:01:49.320
OK, so here I have this weird capsule thingy,

46
00:01:49.320 --> 00:01:51.800
or call it a bean or whatever you wish.

47
00:01:51.800 --> 00:01:54.040
And I just rigged this with a chain rig

48
00:01:54.040 --> 00:01:56.960
with some smooth settings enabled.

49
00:01:56.960 --> 00:01:58.480
So here's my meta rig.

50
00:01:58.480 --> 00:02:02.000
And this is just a Cloud FK chain, so it can bend.

51
00:02:02.000 --> 00:02:03.880
And there is no lattice set up yet whatsoever,

52
00:02:03.880 --> 00:02:05.320
so let's create it.

53
00:02:05.320 --> 00:02:07.960
So I'm just going to go in the meta rig, enter edit mode,

54
00:02:07.960 --> 00:02:11.840
make a new bone with Shift-A, which is invisible.

55
00:02:11.840 --> 00:02:13.200
But there it is.

56
00:02:13.200 --> 00:02:15.920
And I'll just put that one here.

57
00:02:15.920 --> 00:02:17.280
And since it's going to be there,

58
00:02:17.280 --> 00:02:21.080
let's say that I will want to parent it to this default bone,

59
00:02:21.080 --> 00:02:22.720
but I will do that a bit later.

60
00:02:22.720 --> 00:02:27.920
So first things first, let's name this lattice,

61
00:02:27.920 --> 00:02:32.520
and then assign it the rigify type Cloud underscore lattice.

62
00:02:32.520 --> 00:02:34.080
And let's see what settings we have.

63
00:02:34.080 --> 00:02:36.200
We ignore the parenting settings for now.

64
00:02:36.200 --> 00:02:38.040
So as you can see, it's not a whole lot.

65
00:02:38.040 --> 00:02:40.160
And even the option that we do have,

66
00:02:40.160 --> 00:02:42.480
which is the lattice object, is actually optional.

67
00:02:42.480 --> 00:02:44.160
You don't have to specify it because, as you

68
00:02:44.160 --> 00:02:47.160
can see on the tooltip, as long as regenerate is enabled,

69
00:02:47.160 --> 00:02:49.360
we will just get a lattice created for us.

70
00:02:49.360 --> 00:02:50.800
So that's exactly what we want.

71
00:02:50.840 --> 00:02:54.560
So let's just hit Generate, which is Control-Alt-R.

72
00:02:54.560 --> 00:02:55.480
And there you go.

73
00:02:55.480 --> 00:02:57.880
We have a lattice right here, which actually

74
00:02:57.880 --> 00:02:59.360
has a hook modifier.

75
00:02:59.360 --> 00:03:01.240
And what that hook modifier is responsible for

76
00:03:01.240 --> 00:03:03.200
is to make sure that when you move this bone,

77
00:03:03.200 --> 00:03:06.120
the inside part of the lattice actually gets deformed.

78
00:03:06.120 --> 00:03:09.920
And the lattice is also actually parented to the root lattice

79
00:03:09.920 --> 00:03:12.280
lattice bone, which now that I realize

80
00:03:12.280 --> 00:03:13.680
it's a bit of an unfortunate name,

81
00:03:13.680 --> 00:03:16.320
but that is, of course, referring to our cube.

82
00:03:16.320 --> 00:03:18.440
So when you move the cube, the entire lattice

83
00:03:18.440 --> 00:03:19.840
moves along with it.

84
00:03:19.840 --> 00:03:21.120
I hope that makes sense so far.

85
00:03:21.120 --> 00:03:23.920
But as you can see, of course, this does not deform our mesh.

86
00:03:23.920 --> 00:03:26.960
And this is where the modifier that I mentioned comes in.

87
00:03:26.960 --> 00:03:30.920
So if we select our mesh and add the modifier,

88
00:03:30.920 --> 00:03:33.720
we can find eventually the lattice modifier.

89
00:03:33.720 --> 00:03:37.520
And here we can just use the picker to find our lattice.

90
00:03:37.520 --> 00:03:38.160
And there you go.

91
00:03:38.160 --> 00:03:40.120
Suddenly it's being deformed.

92
00:03:40.120 --> 00:03:42.400
And from there, you can hide this lattice

93
00:03:42.400 --> 00:03:45.040
because it's ugly and unnecessary.

94
00:03:45.040 --> 00:03:48.440
So, ma'am, now it will no longer bother you.

95
00:03:48.440 --> 00:03:49.280
And there you go.

96
00:03:49.360 --> 00:03:51.080
You have a lattice deformer that you

97
00:03:51.080 --> 00:03:54.800
can slide around your mesh and scale as well

98
00:03:54.800 --> 00:03:57.000
to change its area of influence.

99
00:03:57.000 --> 00:03:59.320
And yeah, that's pretty much it.

100
00:03:59.320 --> 00:04:01.400
But just as an extra little bonus,

101
00:04:01.400 --> 00:04:04.480
even though I did explain the parenting settings

102
00:04:04.480 --> 00:04:06.800
in a different video, just for the sake of it,

103
00:04:06.800 --> 00:04:09.840
let's parent this to def chain 2.

104
00:04:09.840 --> 00:04:11.480
So I just put it on my clipboard.

105
00:04:11.480 --> 00:04:13.040
And I come back here.

106
00:04:13.040 --> 00:04:15.360
And I will paste it in here.

107
00:04:15.360 --> 00:04:16.120
There we go.

108
00:04:16.120 --> 00:04:19.240
So we can see that this is going to use a bandy parenting

109
00:04:19.360 --> 00:04:24.600
setup, which means the parent of this bone is going to have,

110
00:04:24.600 --> 00:04:27.800
or rather the parent of the parent of this bone,

111
00:04:27.800 --> 00:04:30.040
is going to have an armature constraint, which targets

112
00:04:30.040 --> 00:04:31.760
the bone that we specified.

113
00:04:31.760 --> 00:04:34.200
And that means I just enabled the mechanism layer.

114
00:04:34.200 --> 00:04:36.800
So let me hide that again and this thing.

115
00:04:36.800 --> 00:04:40.120
So when you bend your bendy bones,

116
00:04:40.120 --> 00:04:43.480
the lattice follows the exact deformation precisely.

117
00:04:43.480 --> 00:04:46.600
And that also works for when you use the strategy chain

118
00:04:46.600 --> 00:04:48.400
or whatever it is that you want to do.

119
00:04:48.400 --> 00:04:50.360
And then you can deform with the lattice

120
00:04:50.360 --> 00:04:52.120
on top of your bone deformation.

121
00:04:52.120 --> 00:04:54.400
So this is why I said that I think

122
00:04:54.400 --> 00:04:57.560
lattices work really nicely in cooperation with armature

123
00:04:57.560 --> 00:04:59.200
deformation.

124
00:04:59.200 --> 00:05:00.960
Because, yeah, I mean, just look at it.

125
00:05:00.960 --> 00:05:02.200
It's wonderful.

126
00:05:02.200 --> 00:05:04.320
So yeah, I hope you like it as well.

127
00:05:04.320 --> 00:05:06.960
And if you didn't know how to appreciate lattices before,

128
00:05:06.960 --> 00:05:08.720
then I hope now you do.

129
00:05:08.720 --> 00:05:12.520
And yeah, just slap hundreds of these on your rigs.

130
00:05:12.520 --> 00:05:14.760
Every time there's a problem, we would fix it

131
00:05:14.760 --> 00:05:16.320
by slapping one of these on it.

132
00:05:16.320 --> 00:05:18.040
So yeah, go ham.

133
00:05:18.040 --> 00:05:18.920
Thank you for watching.

134
00:05:18.920 --> 00:05:21.200
And see you in the next one.
