00:00:25.525 --> 00:00:27.125
 Today, we will model

3
00:00:27.125 --> 00:00:29.325
a polygon example directly

4
00:00:29.325 --> 00:00:31.125
Before starting the modeling process,

5
00:00:31.125 --> 00:00:34.375
we will first discuss camera settings

6
00:00:34.375 --> 00:00:37.375
Additionally, we will look at practical approaches

7
00:00:37.375 --> 00:00:39.975
to polygon modeling and its applications

8
00:00:39.975 --> 00:00:43.825
We will create a simple wooden boat as an example

9
00:00:43.825 --> 00:00:47.825
Camera Settings

10
00:00:48.975 --> 00:00:51.325
Let's try and understand

11
00:00:51.325 --> 00:00:54.425
the modeling environment

12
00:00:54.425 --> 00:00:58.875
before diving into modeling

13
00:00:58.875 --> 00:01:03.525
Let's start by looking at the camera settings

14
00:01:04.125 --> 00:01:06.225
As you see here,

15
00:01:06.225 --> 00:01:09.475
a camera’s lens value changes how an image looks

16
00:01:10.426 --> 00:01:14.076
I have brought a sample image to explain this

17
00:01:14.076 --> 00:01:17.926
When we set up the lens value,

18
00:01:17.926 --> 00:01:23.576
Values like 24mm, 35mm, 50mm,

19
00:01:23.576 --> 00:01:26.526
or 300mm

20
00:01:26.526 --> 00:01:31.576
affect the distortion of the subject

21
00:01:33.226 --> 00:01:37.526
People naturally see in the 50mm to 55mm range

22
00:01:37.526 --> 00:01:42.976
So let's say this 55mm is the natural view we have

23
00:01:42.976 --> 00:01:44.626
Maya’s default setting

24
00:01:44.626 --> 00:01:47.026
is about 35mm

25
00:01:47.026 --> 00:01:49.076
If you use reference images

26
00:01:49.076 --> 00:01:52.526
or other images from an external source,

27
00:01:52.526 --> 00:01:54.926
setting the lens to 50mm or 55mm

28
00:01:54.926 --> 00:01:57.926
gives a more natural look

29
00:01:57.926 --> 00:02:02.826
Understanding lens values helps with accurate modeling

30
00:02:02.826 --> 00:02:05.026
For example, a 300mm lens

31
00:02:05.026 --> 00:02:08.226
makes objects look flat

32
00:02:08.226 --> 00:02:11.826
A 24mm lens creates a fisheye effect

33
00:02:11.826 --> 00:02:16.826
Let's take this photo as an example

34
00:02:18.876 --> 00:02:23.826
An 18mm and 300mm image look very different

35
00:02:24.526 --> 00:02:28.826
Let's look at the camera settings

36
00:02:28.826 --> 00:02:31.376
before we move on

37
00:02:31.376 --> 00:02:37.376
I will load a sample image to the Scene

38
00:02:39.526 --> 00:02:41.976
Here is the sample image

39
00:02:41.976 --> 00:02:44.626
Let's check the camera settings

40
00:02:44.626 --> 00:02:49.276
Press Ctrl + A to open the Attribute Editor

41
00:02:49.726 --> 00:02:53.176
In the first tab, no need for other things,

42
00:02:53.176 --> 00:02:58.026
but you will find the Camera Attributes section

43
00:02:58.026 --> 00:03:01.926
The Focal Length value is currently set to 35mm

44
00:03:01.926 --> 00:03:06.326
I usually change this to 55mm
for better accuracy in modeling

45
00:03:06.926 --> 00:03:09.376
Pressing F frames the view to fit the screen

46
00:03:09.376 --> 00:03:13.476
Setting the focal length to 55mm helps

47
00:03:13.476 --> 00:03:17.876
keep the proportions more natural
and prevents distortion while working

48
00:03:19.176 --> 00:03:23.226
Now, let’s test different focal lengths

49
00:03:24.526 --> 00:03:27.427
with the camera settings

50
00:03:29.777 --> 00:03:34.927
I will change the Focal Length to 24mm and press F

51
00:03:34.927 --> 00:03:38.877
It is now more distorted than at 55mm

52
00:03:38.877 --> 00:03:45.027
Next, I will try 15mm, something more extreme

53
00:03:46.177 --> 00:03:48.977
Pressing F and zooming in

54
00:03:48.977 --> 00:03:50.927
shows an even stronger distortion,

55
00:03:50.927 --> 00:03:54.177
similar to a fisheye lens

56
00:03:55.227 --> 00:03:58.527
Now, I will set it to 5mm

57
00:04:00.727 --> 00:04:04.177
Pressing F again, full frame,

58
00:04:04.177 --> 00:04:06.727
and it shows an extreme fisheye effect

59
00:04:08.327 --> 00:04:12.427
Let’s try 300mm this time

60
00:04:13.427 --> 00:04:16.127
This creates a telephoto effect

61
00:04:17.177 --> 00:04:20.177
Pressing F frames the image,

62
00:04:20.177 --> 00:04:24.477
and you can see that it looks flatter,

63
00:04:24.827 --> 00:04:26.427
much flatter than before

64
00:04:26.427 --> 00:04:29.077
So what I do is this

65
00:04:30.077 --> 00:04:35.627
Using 55mm generally produces the best results for me,

66
00:04:35.627 --> 00:04:40.677
And I'm sure it's a nice place to start for you too

67
00:04:40.677 --> 00:04:44.677
Applying Polygon Models

68
00:04:44.677 --> 00:04:47.527
That was a brief explanation about the camera

69
00:04:47.527 --> 00:04:53.177
Now, let’s move on to polygon modeling

70
00:04:53.177 --> 00:04:55.427
I have prepared a sample for this,

71
00:04:55.427 --> 00:04:57.827
so let me explain briefly

72
00:04:57.827 --> 00:05:01.077
I downloaded this image from the internet

73
00:05:02.677 --> 00:05:05.377
It's something I downloaded

74
00:05:05.377 --> 00:05:11.277
Let's try modeling this wooden boat

75
00:05:11.977 --> 00:05:15.427
I will go through each step

76
00:05:15.427 --> 00:05:18.627
so you can follow along for the modeling process

77
00:05:18.627 --> 00:05:21.727
and create the model together

78
00:05:23.627 --> 00:05:27.327
First, in Photoshop,

79
00:05:27.327 --> 00:05:31.377
I have a side view,

80
00:05:31.377 --> 00:05:35.077
a top view,

81
00:05:35.077 --> 00:05:38.327
a front view, and a rear view

82
00:05:38.327 --> 00:05:43.227
Let's prepare four images

83
00:05:43.227 --> 00:05:49.328
by cutting them separately

84
00:05:50.278 --> 00:05:54.278
I have the four images ready

85
00:05:54.278 --> 00:05:56.928
The top view,

86
00:05:56.928 --> 00:06:03.728
the side view,

87
00:06:03.728 --> 00:06:09.228
the front view,

88
00:06:09.228 --> 00:06:13.178
and the rear view

89
00:06:14.578 --> 00:06:18.078
Those are the four I have

90
00:06:18.078 --> 00:06:22.278
So go ahead and do the same

91
00:06:23.078 --> 00:06:26.828
Now, let’s bring these images into Maya
and use them for modeling

92
00:06:27.628 --> 00:06:31.278
I will close the reference images and open a new scene

93
00:06:31.278 --> 00:06:34.178
New Scene, and open it up

94
00:06:34.978 --> 00:06:39.978
To get an idea of the boat’s size,

95
00:06:39.978 --> 00:06:42.428
 will start by creating a polygon cube

96
00:06:42.428 --> 00:06:44.578
as a rough template model

97
00:06:44.578 --> 00:06:49.278
Pressing spacebar splits the view
into four different perspectives

98
00:06:49.278 --> 00:06:52.778
I will now use the scale tool to adjust the size of the cube

99
00:06:53.878 --> 00:07:00.028
Looking at the side view, the boat seems

100
00:07:00.028 --> 00:07:10.278
to be a bit longer, so I will scale it up accordingly

101
00:07:11.978 --> 00:07:16.678
You can manually adjust each of the four views,

102
00:07:16.678 --> 00:07:18.728
but pressing Shift + A

103
00:07:18.728 --> 00:07:26.128
will frame the entire object to full screen

104
00:07:27.828 --> 00:07:34.178
Looking at the front view, the boat shape is roughly set

105
00:07:39.478 --> 00:07:41.778
 I'll adjust the size accordingly,

106
00:07:41.778 --> 00:07:46.828
but it doesn't need to be perfectly precise

107
00:07:46.828 --> 00:07:52.228
Just keep in mind that the reference image
will fit within this range

108
00:07:52.228 --> 00:07:56.128
Next, I’ll template this object

109
00:07:56.128 --> 00:08:02.878
Press spacebar, right-click,

110
00:08:02.878 --> 00:08:04.229
and select Toggle Template

111
00:08:04.229 --> 00:08:07.429
You can also use the Toggle Template option manually

112
00:08:08.429 --> 00:08:12.979
Alternatively, Ctrl +  Z, now press Ctrl + A,

113
00:08:14.679 --> 00:08:17.779
go to the first tab,

114
00:08:17.779 --> 00:08:21.779
click Display Options, and you will find

115
00:08:21.779 --> 00:08:24.929
the Template option there as well

116
00:08:24.929 --> 00:08:26.729
That's another way of doing it

117
00:08:28.229 --> 00:08:30.529
A common method used in practice

118
00:08:32.179 --> 00:08:37.379
is through the Display Layer panel

119
00:08:37.379 --> 00:08:39.879
With the object selected,

120
00:08:40.779 --> 00:08:44.429
click the last icon

121
00:08:44.429 --> 00:08:47.779
Create a new layer and assign the selected object

122
00:08:47.779 --> 00:08:50.779
This works similarly to layers in Photoshop

123
00:08:50.779 --> 00:08:52.629
It's the concept of layers

124
00:08:52.629 --> 00:08:54.329
just like in Photoshop

125
00:08:54.329 --> 00:08:57.929
So the object is

126
00:08:57.929 --> 00:08:59.629
now in a display layer,

127
00:08:59.629 --> 00:09:03.779
allowing you to toggle its visibility

128
00:09:03.779 --> 00:09:08.729
If you look at the layer, you’ll see a P symbol

129
00:09:08.729 --> 00:09:11.079
Clicking it

130
00:09:11.079 --> 00:09:12.179
changes it to T,

131
00:09:12.179 --> 00:09:14.229
which stands for Template

132
00:09:14.229 --> 00:09:16.779
So with this simple setup,

133
00:09:16.779 --> 00:09:21.079
now the object is locked as a reference

134
00:09:21.079 --> 00:09:25.279
for us to look at its size

135
00:09:26.529 --> 00:09:30.479
Now, I’ll import the four prepared reference images

136
00:09:30.479 --> 00:09:33.329
First, in the 4-view layout,

137
00:09:33.329 --> 00:09:36.979
select the side view

138
00:09:36.979 --> 00:09:39.729
Go with Select Camera

139
00:09:39.729 --> 00:09:43.029
to make sure the side camera is selected

140
00:09:43.029 --> 00:09:45.529
You can check in Outliner

141
00:09:45.529 --> 00:09:47.529
that the side view camera is selected

142
00:09:47.529 --> 00:09:50.529
This is the default camera in Maya

143
00:09:50.529 --> 00:09:52.779
View - Select Camera

144
00:09:52.779 --> 00:09:54.579
Now, Ctrl + A

145
00:09:54.579 --> 00:09:58.979
Go to the second Shape tab, scroll down,

146
00:09:58.979 --> 00:10:03.529
and find the small triangle

147
00:10:03.529 --> 00:10:06.779
next to Environment

148
00:10:06.779 --> 00:10:11.279
Click to expand the menu

149
00:10:11.279 --> 00:10:13.529
Now, we can make the image plane

150
00:10:13.529 --> 00:10:16.380
Click Create Image Plane

151
00:10:16.880 --> 00:10:21.980
to generate an image plane for the side view

152
00:10:27.730 --> 00:10:29.780
With the image plane selected,

153
00:10:32.330 --> 00:10:35.930
go to the second Shape tab in the Attribute Editor

154
00:10:36.930 --> 00:10:39.280
Under Texture Filter, you’ll find Image Name

155
00:10:39.280 --> 00:10:42.130
Click the directory folder

156
00:10:42.130 --> 00:10:43.980
to import an image

157
00:10:43.980 --> 00:10:47.680
I have already copied my images

158
00:10:47.680 --> 00:10:48.830
into this directory

159
00:10:48.830 --> 00:10:53.330
If you don’t see your file, change the filter to All Files

160
00:10:55.930 --> 00:10:58.130
Since this is the side view,

161
00:10:58.130 --> 00:11:01.480
I’ll select the side view image

162
00:11:02.330 --> 00:11:05.230
It didn’t load correctly

163
00:11:05.230 --> 00:11:10.030
That’s because the file format is not JPG

164
00:11:10.030 --> 00:11:12.880
or another supported format

165
00:11:12.880 --> 00:11:16.330
I’ll go back to Photoshop

166
00:11:16.330 --> 00:11:18.830
and convert all four images to JPG format

167
00:11:20.180 --> 00:11:24.480
Now that I’ve completed the conversion

168
00:11:24.480 --> 00:11:27.180
for all four images,

169
00:11:27.180 --> 00:11:30.330
I’ll reload the side view image in JPG format

170
00:11:31.580 --> 00:11:36.380
Side view, let's open the image

171
00:11:37.330 --> 00:11:42.680
The image has been loaded, but it appears too small

172
00:11:43.280 --> 00:11:48.480
I’ll use the Scale Tool to enlarge it

173
00:11:50.680 --> 00:11:52.680
I'll adjust the size

174
00:11:52.680 --> 00:11:56.230
to match the template model

175
00:11:57.930 --> 00:12:02.280
Since having the image in the center

176
00:12:02.280 --> 00:12:03.830
would obstruct modeling,

177
00:12:03.830 --> 00:12:05.630
I’ll move it slightly to the side

178
00:12:05.630 --> 00:12:08.230
using the Move Tool

179
00:12:08.880 --> 00:12:13.880
Now, let’s import the top view image

180
00:12:16.130 --> 00:12:20.030
Switch to the top view,

181
00:12:20.030 --> 00:12:24.180
go to View → Select Camera,

182
00:12:24.180 --> 00:12:27.380
and make sure the top camera is selected

183
00:12:27.380 --> 00:12:29.330
Press Ctrl + A

184
00:12:29.330 --> 00:12:34.030
to open the Attribute Editor again

185
00:12:34.681 --> 00:12:41.081
Just like before, go to Environment,
click Create Image Plane,

186
00:12:41.081 --> 00:12:43.181
and load the image

187
00:12:43.681 --> 00:12:45.781
Switch to Perspective View to check the placement

188
00:12:46.431 --> 00:12:49.131
Now, I’ll import the top view image and open it

189
00:12:50.231 --> 00:12:52.831
This is the top view

190
00:12:53.681 --> 00:12:57.481
Again, the image appears too small,

191
00:12:57.481 --> 00:13:00.531
so I’ll use the Scale Tool to resize it

192
00:13:06.681 --> 00:13:09.031
Since it’s hard to determine the exact size,

193
00:13:09.031 --> 00:13:14.031
I’ll align the side view image to the center grid for reference

194
00:13:14.031 --> 00:13:18.331
Using Grid Snap, or the X key,

195
00:13:18.331 --> 00:13:21.031
I’ll snap it to the center to ensure accuracy

196
00:13:21.031 --> 00:13:23.281
With the side view properly aligned,

197
00:13:23.831 --> 00:13:29.481
I can now adjust the top view size more accurately

198
00:13:30.781 --> 00:13:35.231
The front-to-back length seems too short,
so I’ll stretch it using Scale

199
00:13:40.331 --> 00:13:43.081
That looks about right

200
00:13:46.081 --> 00:13:51.181
Let's move it slightly to fit it perfectly

201
00:13:51.181 --> 00:13:53.331
Let's enlarge it a little more

202
00:13:56.881 --> 00:14:02.405
Now it looks perfectly in size

203
00:14:05.981 --> 00:14:09.381
If it's difficult to match the sizes precisely,

204
00:14:11.781 --> 00:14:15.731
press Ctrl + A, scroll down,

205
00:14:18.781 --> 00:14:23.731
and adjust the Width and Height values

206
00:14:23.731 --> 00:14:25.431
under Placement Extras

207
00:14:25.431 --> 00:14:29.081
This allows for finer adjustments

208
00:14:29.081 --> 00:14:33.281
for the Width and the Height values

209
00:14:40.331 --> 00:14:42.481
I'll increase the size slightly

210
00:14:46.031 --> 00:14:50.332
and align it at the bottom

211
00:14:50.832 --> 00:14:58.782
Now, let's load the front view image

212
00:14:58.782 --> 00:15:02.232
Go to the front view,

213
00:15:02.232 --> 00:15:07.832
then select View → Select Camera to confirm

214
00:15:07.832 --> 00:15:09.982
that the front camera is selected in Outliner

215
00:15:09.982 --> 00:15:13.782
With the camera selected, press Ctrl + A

216
00:15:13.782 --> 00:15:16.832
to open the Attribute Editor

217
00:15:16.832 --> 00:15:23.532
In the Shape tab, click Environment,

218
00:15:23.532 --> 00:15:26.032
then select Create Image Plane

219
00:15:28.382 --> 00:15:31.232
Now, I'll load the front view image

220
00:15:32.682 --> 00:15:35.905
The image appears at the top, so open

221
00:15:37.782 --> 00:15:40.782
Switching to Perspective View,
I'll scale the image to the appropriate size

222
00:15:46.432 --> 00:15:51.982
Since it's not centered properly, I'll align it to the center

223
00:15:54.282 --> 00:15:59.282
Placing it in front might be more convenient for modeling

224
00:16:03.832 --> 00:16:06.882
Before moving it,

225
00:16:06.882 --> 00:16:08.932
I'll adjust the size

226
00:16:08.932 --> 00:16:12.232
to match the boat’s widest section

227
00:16:12.232 --> 00:16:16.782
Let's use the widest part

228
00:16:16.782 --> 00:16:21.482
The boat's widest part appears to be around here,

229
00:16:21.482 --> 00:16:29.082
so I'll scale it accordingly to fit it perfectly

230
00:16:34.782 --> 00:16:37.282
Since the pivot point is off-center,

231
00:16:37.282 --> 00:16:42.382
press D to move the pivot and align it with the center

232
00:16:42.382 --> 00:16:45.332
To the center, press D to align

233
00:16:45.332 --> 00:16:47.632
Release the D key, and the pivot will be set

234
00:16:47.632 --> 00:16:50.032
With grid snapping,

235
00:16:51.282 --> 00:16:53.182
or the X key, I'll lock the object to the X-axis

236
00:16:53.182 --> 00:16:56.932
and snap it to the correct position

237
00:16:57.632 --> 00:17:03.082
Once the front view is properly aligned,

238
00:17:03.082 --> 00:17:05.733
modeling should be easier

239
00:17:08.033 --> 00:17:10.933
I'll also adjust the height to align the bottom of the boat

240
00:17:13.183 --> 00:17:22.083
The bottom edge now roughly matches the reference

241
00:17:34.133 --> 00:17:39.483
If needed, you can also

242
00:17:39.483 --> 00:17:42.783
load a rear view later,

243
00:17:42.783 --> 00:17:46.533
but these three images

244
00:17:46.533 --> 00:17:47.683
should be enough for modeling

245
00:17:47.683 --> 00:17:51.033
In Perspective View, the grid can be distracting,

246
00:17:51.033 --> 00:17:54.233
so I'll turn it off

247
00:17:55.783 --> 00:17:58.083
Now, the initial setup

248
00:17:58.083 --> 00:18:01.033
for modeling is complete

249
00:18:01.733 --> 00:18:04.883
Let's start modeling

250
00:18:04.883 --> 00:18:09.383
Since the template object is no longer needed,

251
00:18:09.383 --> 00:18:15.733
I'll hide it in the Display Layer settings under Channel Box

252
00:18:15.733 --> 00:18:18.733
by disabling Visibility

253
00:18:19.133 --> 00:18:21.433
Also, everyone,

254
00:18:21.433 --> 00:18:24.283
make sure to save your work as you go

255
00:18:25.733 --> 00:18:31.483
To begin modeling the basic shape,

256
00:18:32.783 --> 00:18:35.233
I'll define the overall structure

257
00:18:36.133 --> 00:18:44.605
I'll use a polygon cube to form the base shape

258
00:18:55.333 --> 00:18:57.683
Enabling wireframe mode

259
00:18:57.683 --> 00:18:59.183
will make editing easier

260
00:19:07.933 --> 00:19:13.583
That's how it has been shaped

261
00:19:15.033 --> 00:19:17.433
We can halve this here

262
00:19:17.433 --> 00:19:19.033
Since the boat

263
00:19:19.033 --> 00:19:23.783
is a symmetrical object,

264
00:19:23.783 --> 00:19:25.633
because of that,

265
00:19:25.633 --> 00:19:28.633
I do not need to model everything

266
00:19:28.633 --> 00:19:32.483
I only need to model one half and mirror it later

267
00:19:32.483 --> 00:19:36.184
It will create one whole object

268
00:19:36.184 --> 00:19:39.134
This method is common for characters

269
00:19:39.134 --> 00:19:42.384
We model half and mirror it to complete the full shape

270
00:19:42.384 --> 00:19:47.584
To split the object in half, I'll use the Multi-Cut Tool

271
00:19:48.984 --> 00:19:51.334
Hold Shift,

272
00:19:52.334 --> 00:19:53.934
select Multi-Cut Tool,

273
00:19:53.934 --> 00:19:59.034
then right-click to confirm selection

274
00:19:59.034 --> 00:20:01.484
Release to confirm the selection

275
00:20:02.384 --> 00:20:10.284
So the color is, not exactly blue,

276
00:20:10.284 --> 00:20:16.034
but something closer to being cyan

277
00:20:16.984 --> 00:20:20.484
In top view, I'll press Shift

278
00:20:20.484 --> 00:20:21.984
and drag downward

279
00:20:21.984 --> 00:20:24.434
to snap the cut vertically

280
00:20:24.434 --> 00:20:27.084
Since this is the vertical view,

281
00:20:27.084 --> 00:20:29.334
set it to vertical, and click

282
00:20:29.334 --> 00:20:32.784
Now, go to Perspective View to check

283
00:20:32.784 --> 00:20:36.134
The top and bottom are now evenly split

284
00:20:36.634 --> 00:20:41.634
Since the center isn't perfectly aligned,

285
00:20:41.634 --> 00:20:50.684
I'll select vertices in top view

286
00:20:50.684 --> 00:20:55.334
and snap them to the center grid

287
00:20:55.334 --> 00:20:58.184
So it is all aligned

288
00:21:02.384 --> 00:21:05.734
Switching to shaded mode, I can check the shape

289
00:21:07.884 --> 00:21:10.384
To see the wireframe,

290
00:21:10.384 --> 00:21:13.284
press Alt + 5 to toggle wireframe mode

291
00:21:14.784 --> 00:21:16.834
We are starting with the big shapes

292
00:21:16.834 --> 00:21:20.884
I will show you in top view

293
00:21:20.884 --> 00:21:23.434
The widest section of the boat appears to be around here,

294
00:21:23.434 --> 00:21:29.684
so I'll add another cut using the Multi-Cut Tool

295
00:21:33.184 --> 00:21:36.934
Since only half of the boat needs to be modeled,

296
00:21:36.934 --> 00:21:39.685
I'll delete one half

297
00:21:41.385 --> 00:21:44.235
Selecting one side,

298
00:21:44.235 --> 00:21:47.335
either left or right, doesn't really matter,

299
00:21:47.335 --> 00:21:51.435
I'll delete the unnecessary half

300
00:21:52.135 --> 00:21:57.235
To check the polygon’s boundary edges,

301
00:21:57.235 --> 00:22:01.985
press Ctrl + A, go to the Shape tab,

302
00:22:01.985 --> 00:22:04.635
and click Mesh Component Display

303
00:22:05.485 --> 00:22:07.785
As I mentioned last time,

304
00:22:07.785 --> 00:22:12.535
click Display Borders to highlight the boundaries

305
00:22:12.535 --> 00:22:17.935
This makes it easier to check the polygon,

306
00:22:17.935 --> 00:22:20.935
for open edges or closed seams

307
00:22:20.935 --> 00:22:25.085
when you need to later

308
00:22:26.485 --> 00:22:32.085
Now, I'll mirror the other half of the model

309
00:22:34.335 --> 00:22:40.435
Go to Edit, then scroll down

310
00:22:41.435 --> 00:22:44.835
to Duplicate Special

311
00:22:44.835 --> 00:22:46.885
Open the Duplicate Special options

312
00:22:46.885 --> 00:22:50.235
by clicking the settings icon

313
00:22:53.935 --> 00:22:58.555
The Duplicate Special options window will appear

314
00:23:02.235 --> 00:23:05.335
First, reset the settings to default

315
00:23:05.335 --> 00:23:08.185
in case previous adjustments were made

316
00:23:08.185 --> 00:23:10.335
You may have been testing

317
00:23:10.335 --> 00:23:12.585
for different options before this

318
00:23:12.585 --> 00:23:15.885
So just in case, let's reset it

319
00:23:15.885 --> 00:23:17.235
And here,

320
00:23:18.335 --> 00:23:20.535
you need to check the key values

321
00:23:20.535 --> 00:23:23.685
The first one is Translate,

322
00:23:23.685 --> 00:23:28.085
then Rotate, and finally Scale

323
00:23:28.085 --> 00:23:31.735
The first one is X, second Y,

324
00:23:31.735 --> 00:23:35.935
and the last one is Z

325
00:23:36.735 --> 00:23:41.385
So down here, we need the x-axis

326
00:23:41.385 --> 00:23:46.585
And for the x-axis, we need to do the following

327
00:23:46.585 --> 00:23:49.735
This is the positive one, and we require its negative X copy

328
00:23:49.735 --> 00:23:52.685
Since we've scaled the model,

329
00:23:52.685 --> 00:23:59.186
mirroring now might cause errors

330
00:23:59.186 --> 00:24:00.836
It will not look accurate

331
00:24:00.836 --> 00:24:03.886
So let's clear the history

332
00:24:03.886 --> 00:24:07.286
by pressing Alt + Shift + D

333
00:24:07.286 --> 00:24:09.136
Now, the history is removed

334
00:24:09.136 --> 00:24:12.786
Now, we need to freeze transformations

335
00:24:14.536 --> 00:24:18.186
You can check for the values here in this Channel Box

336
00:24:18.186 --> 00:24:20.836
It has all the values we've been working with

337
00:24:21.886 --> 00:24:25.536
What we need is to set the model's scale to 1:1

338
00:24:25.536 --> 00:24:29.236
before mirroring, which will go to -1

339
00:24:29.236 --> 00:24:30.336
to mirror the one we have

340
00:24:30.336 --> 00:24:33.686
Since we have all the changed values,

341
00:24:33.686 --> 00:24:36.586
we need to freeze these to reset

342
00:24:36.586 --> 00:24:38.936
Then we get 1

343
00:24:38.936 --> 00:24:43.786
We also covered this in the last session

344
00:24:43.786 --> 00:24:47.236
Open Modify and go to Freeze Transformations

345
00:24:47.236 --> 00:24:50.586
Click it, and you'll see the transformation values

346
00:24:50.586 --> 00:24:51.586
reset in the Channel Box

347
00:24:51.586 --> 00:24:56.786
I will click on Freeze Transformations

348
00:24:56.786 --> 00:24:59.586
Now, it is all reset

349
00:24:59.586 --> 00:25:03.086
The scale is now 1:1

350
00:25:03.086 --> 00:25:06.936
What we need is the minus value

351
00:25:06.936 --> 00:25:09.986
So this is the first one of X, Y, and Z, which is X

352
00:25:09.986 --> 00:25:14.436
What we need is not +1 but -1

353
00:25:14.436 --> 00:25:18.486
So enter -1

354
00:25:19.936 --> 00:25:22.986
Now, apply this Duplicate Special

355
00:25:24.736 --> 00:25:27.886
Now, the mirrored copy is created

356
00:25:29.436 --> 00:25:35.136
Let's move the mirrored object

357
00:25:35.136 --> 00:25:37.886
But it does not follow the original

358
00:25:37.886 --> 00:25:45.136
We need it to be linked dynamically,

359
00:25:45.136 --> 00:25:47.386
so that it works as a perfect mirror

360
00:25:47.386 --> 00:25:50.886
So let's set it up again

361
00:25:50.886 --> 00:25:53.436
Remove this copy

362
00:25:53.436 --> 00:25:55.736
Go back to the Duplicate Special Settings

363
00:25:59.336 --> 00:26:03.086
Here, instead of Copy, select Instance

364
00:26:03.086 --> 00:26:06.336
Select Instance, and once again,

365
00:26:06.886 --> 00:26:09.136
click Duplicate Special

366
00:26:11.236 --> 00:26:13.837
Now, let's move the original

367
00:26:15.087 --> 00:26:18.637
Now, the mirrored half is

368
00:26:18.637 --> 00:26:20.487
also moving in perfect symmetry

369
00:26:20.487 --> 00:26:26.887
Switch to top view and adjust the shape

370
00:26:27.787 --> 00:26:34.237
Refine the top and side shapes to match the image

371
00:26:37.037 --> 00:26:39.637
Now, the boat appears very big

372
00:26:40.237 --> 00:26:45.087
Even from the back,

373
00:26:45.087 --> 00:26:47.937
the back view is misaligned, so let's reposition it

374
00:26:54.387 --> 00:26:57.437
So, let's refine the polygon shape

375
00:26:57.437 --> 00:26:59.737
This is the most prominent part

376
00:26:59.737 --> 00:27:03.737
So use Multi-Cut Tool to add a division

377
00:27:03.737 --> 00:27:08.737
Hold Shift, then cut along the shape

378
00:27:10.337 --> 00:27:14.837
Grab on the vertex

379
00:27:15.587 --> 00:27:18.187
Since the image plane is active,

380
00:27:18.187 --> 00:27:21.237
right-clicking over it

381
00:27:21.237 --> 00:27:22.237
brings up unwanted options

382
00:27:22.237 --> 00:27:26.687
Make sure to right-click on an empty area

383
00:27:26.687 --> 00:27:30.887
while the polygon is selected,

384
00:27:30.887 --> 00:27:32.987
before choosing Vertex mode

385
00:27:32.987 --> 00:27:35.837
If this is too much work,

386
00:27:35.837 --> 00:27:39.587
go to Show under View panel

387
00:27:39.587 --> 00:27:42.887
Go to Viewport and go down

388
00:27:43.937 --> 00:27:46.687
to find Image Planes

389
00:27:46.687 --> 00:27:49.687
Disable it to remove it, which is more convenient

390
00:27:49.687 --> 00:27:53.987
It also says Alt + 4 can do the same thing

391
00:27:53.987 --> 00:27:55.687
Let's try the Alt + 4 method

392
00:27:56.937 --> 00:27:59.687
You can work on it without the image

393
00:28:00.987 --> 00:28:03.237
I don't mind having it, so I will keep it here

394
00:28:10.137 --> 00:28:15.987
So let's shape the boat

395
00:28:20.387 --> 00:28:22.737
Now, on the side view,

396
00:28:29.637 --> 00:28:32.187
let's use the Scale key

397
00:28:32.187 --> 00:28:37.005
You could also use Rotate

398
00:28:42.338 --> 00:28:44.755
Use Move to align

399
00:28:49.188 --> 00:28:53.438
From the top view, the boat has a streamlined shape

400
00:28:53.438 --> 00:28:56.638
So I'll split it twice, once near the top

401
00:28:56.638 --> 00:28:57.738
and once near the bottom

402
00:28:57.738 --> 00:29:01.938
Hold Shift, use the Multi-Cut Tool,

403
00:29:01.938 --> 00:29:06.488
and cut vertically along the shape

404
00:29:07.788 --> 00:29:10.755
Now the shape is divided

405
00:29:13.938 --> 00:29:16.555
Adjust the shape as needed

406
00:29:29.538 --> 00:29:34.838
If some sections are unnecessary, select and delete them

407
00:29:35.138 --> 00:29:37.938
for a cleaner workflow

408
00:29:42.488 --> 00:29:44.938
As you work,

409
00:29:44.938 --> 00:29:47.038
you’ll see a history log in the Channel Box

410
00:29:47.038 --> 00:29:50.738
under the Input Nodes

411
00:29:50.738 --> 00:29:55.838
If you don’t need this history,

412
00:29:55.838 --> 00:29:57.988
 it's best to clear it periodically

413
00:29:57.988 --> 00:30:02.238
Press Alt + Shift + D to delete the history

414
00:30:04.438 --> 00:30:08.588
This helps prevent unnecessary data buildup

415
00:30:08.588 --> 00:30:14.138
The inside of the model might appear too dark

416
00:30:14.138 --> 00:30:17.638
To improve visibility, enable default lighting,

417
00:30:17.638 --> 00:30:20.538
then check Two-Sided Lighting

418
00:30:20.538 --> 00:30:22.488
This ensures

419
00:30:22.488 --> 00:30:25.838
the inside and outside display correctly

420
00:30:25.838 --> 00:30:29.138
This makes modeling smoother

421
00:30:29.838 --> 00:30:32.388
And, let's go back and see

422
00:30:32.388 --> 00:30:35.588
what I wanted to explain further

423
00:30:35.588 --> 00:30:37.838
before I continued modeling

424
00:30:37.838 --> 00:30:40.538
This is completely fine

425
00:30:40.538 --> 00:30:43.638
to model it like this

426
00:30:44.638 --> 00:30:47.889
But I like to use a more advanced approach

427
00:30:47.889 --> 00:30:50.639
Rather than this basic method,

428
00:30:50.639 --> 00:30:52.989
there are other modeling techniques,

429
00:30:54.589 --> 00:30:58.239
something more advanced

430
00:30:58.239 --> 00:31:02.439
Let me demonstrate that

431
00:31:02.839 --> 00:31:05.839
To explain more about curves,

432
00:31:05.839 --> 00:31:07.589
I will open a new scene

433
00:31:08.139 --> 00:31:09.689
and enable the grid

434
00:31:10.539 --> 00:31:13.339
Let me talk about curves now

435
00:31:13.739 --> 00:31:16.639
Mastering curves

436
00:31:16.639 --> 00:31:21.689
makes polygon modeling more efficient

437
00:31:21.689 --> 00:31:24.789
It speeds up the process

438
00:31:26.039 --> 00:31:29.139
Technically, curves belong to NURBS modeling,

439
00:31:29.139 --> 00:31:32.239
and they are similar to NURBS modeling

440
00:31:32.239 --> 00:31:34.389
But, mastering these

441
00:31:34.389 --> 00:31:39.039
can still enhance polygon modeling

442
00:31:39.039 --> 00:31:43.039
for a quicker and a more accurate work

443
00:31:43.039 --> 00:31:45.989
Let's go to the side view

444
00:31:48.639 --> 00:31:55.289
and draw a basic profile shape using the CV Curve Tool

445
00:31:55.289 --> 00:31:59.989
Let's say this is the rough shape

446
00:32:00.389 --> 00:32:02.789
Let's duplicate it

447
00:32:04.789 --> 00:32:08.089
Now, we have two NURBS curves

448
00:32:08.089 --> 00:32:11.305
I will enable component display

449
00:32:11.939 --> 00:32:18.739
Now, using EP Curve Tool,

450
00:32:18.739 --> 00:32:21.839
I will create a path between the two curves

451
00:32:21.839 --> 00:32:24.639
By holding C, I can snap to the curve

452
00:32:24.639 --> 00:32:28.439
Now, it's properly connected

453
00:32:28.889 --> 00:32:30.889
Press Enter to confirm

454
00:32:30.889 --> 00:32:33.239
Press G to repeat the command

455
00:32:35.489 --> 00:32:37.989
Let me explain with what we have

456
00:32:38.989 --> 00:32:42.689
Let's enable the component

457
00:32:46.855 --> 00:32:48.555
What I am about to discuss

458
00:32:49.689 --> 00:32:53.189
is generating a surface

459
00:32:53.189 --> 00:32:55.339
along these curves

460
00:32:55.339 --> 00:32:59.039
Maya has a tool for this,

461
00:32:59.039 --> 00:33:01.239
though it is still in the realm of NURBS

462
00:33:01.239 --> 00:33:04.390
Still, let's go for it

463
00:33:04.390 --> 00:33:08.140
Go to the modeling menu

464
00:33:08.140 --> 00:33:12.840
and find Surfaces, and go down

465
00:33:12.840 --> 00:33:14.390
to find Birail

466
00:33:14.390 --> 00:33:16.940
Let me separate the Birail Tool menu

467
00:33:16.940 --> 00:33:22.340
So here, we have Birail 1, Birail 2,

468
00:33:22.340 --> 00:33:25.890
and Birail 3+, plus alpha

469
00:33:25.890 --> 00:33:30.240
Let me demonstrate how one could use this

470
00:33:31.440 --> 00:33:34.040
Let's try Birail 1 Tool

471
00:33:35.390 --> 00:33:39.940
The help line at the bottom

472
00:33:41.090 --> 00:33:42.640
says, Select the profile curve

473
00:33:42.640 --> 00:33:45.990
So it wants me to select a curve

474
00:33:45.990 --> 00:33:50.090
So these two curves

475
00:33:50.090 --> 00:33:52.490
are rail curves

476
00:33:52.490 --> 00:33:55.840
I will set this one as the profile curve

477
00:33:55.840 --> 00:33:59.240
So select profile curve

478
00:33:59.240 --> 00:34:03.790
The help line says, now,

479
00:34:05.440 --> 00:34:09.590
select two rail curves, which can be one, and now two

480
00:34:09.590 --> 00:34:12.140
So now we have a surface

481
00:34:12.140 --> 00:34:13.990
Since this is flipped,

482
00:34:14.940 --> 00:34:19.590
enable Two-Sided Lighting in the Lighting menu

483
00:34:19.590 --> 00:34:23.190
This technique is useful

484
00:34:23.190 --> 00:34:26.590
because it preserves history

485
00:34:27.790 --> 00:34:30.240
Toggle the wireframe

486
00:34:30.840 --> 00:34:32.890
Now, let's edit this

487
00:34:32.890 --> 00:34:34.740
What happens is this

488
00:34:34.740 --> 00:34:38.740
Moving the profile curve

489
00:34:38.740 --> 00:34:42.090
automatically updates the surface

490
00:34:43.890 --> 00:34:46.755
Let's try moving it like this

491
00:34:49.890 --> 00:34:53.690
Now, let's add

492
00:34:53.690 --> 00:34:55.540
another profile curve

493
00:34:58.240 --> 00:35:03.040
Create - Curve Tools - EP Curve Tool

494
00:35:03.040 --> 00:35:08.440
Snap to the center again

495
00:35:08.440 --> 00:35:14.590
Now, I'll extend the bottom

496
00:35:14.590 --> 00:35:17.790
The two rail curves and the profile curve

497
00:35:17.790 --> 00:35:21.391
should always meet

498
00:35:21.391 --> 00:35:25.341
No, let's work on this Birail 2 Tool

499
00:35:25.341 --> 00:35:27.291
Now, the system asks

500
00:35:27.291 --> 00:35:30.041
for two profile curves

501
00:35:30.041 --> 00:35:33.091
So select two

502
00:35:33.091 --> 00:35:35.941
Now, it says we need two more rail curves

503
00:35:35.941 --> 00:35:39.341
So select everything

504
00:35:40.591 --> 00:35:45.691
Now, we get this surface

505
00:35:45.691 --> 00:35:50.391
Because of the second profile curve,
the shape bends downward

506
00:35:50.391 --> 00:35:53.991
 Since the history is still active, we can edit it freely

507
00:35:56.541 --> 00:35:58.941
Using profile and rail curves,

508
00:35:58.941 --> 00:36:06.241
we can create various complex shapes

509
00:36:06.541 --> 00:36:08.291
Let’s try another example

510
00:36:09.891 --> 00:36:13.591
Go to Create → Curve Tools → EP Curve Tool

511
00:36:17.041 --> 00:36:20.791
This time, I’ll snap the curve at this position

512
00:36:24.091 --> 00:36:29.041
Toggle the visibility

513
00:36:32.841 --> 00:36:38.441
and adjust the shape accordingly

514
00:36:41.341 --> 00:36:45.991
Now, we have the third one

515
00:36:45.991 --> 00:36:48.491
We have Birail 1, Birail 2, and Birail 3+

516
00:36:48.491 --> 00:36:51.441
If there are three or more profile curves, we use Birail 3+

517
00:36:51.441 --> 00:36:54.591
Let’s test it now

518
00:36:54.591 --> 00:36:57.791
First, select all profile curves as instructed

519
00:36:57.791 --> 00:37:01.091
Any number of profile curves

520
00:37:01.091 --> 00:37:06.441
Now we need to select the rail curves

521
00:37:06.441 --> 00:37:12.441
Then, select the rail curves and press Enter

522
00:37:12.741 --> 00:37:14.341
Now, the shape is generated

523
00:37:15.891 --> 00:37:22.491
If we select the third profile curve and modify it,

524
00:37:22.491 --> 00:37:26.091
we can create any desired shape

525
00:37:26.091 --> 00:37:29.341
We can scale it like this too

526
00:37:32.291 --> 00:37:36.091
Since we are working with polygon modeling,

527
00:37:36.091 --> 00:37:39.191
we need to convert the NURBS surface into polygons

528
00:37:39.191 --> 00:37:40.791
Maya has a conversion tool for this

529
00:37:40.791 --> 00:37:44.691
Let's take a look at this converting process

530
00:37:44.691 --> 00:37:47.241
It's an important detail

531
00:37:47.241 --> 00:37:52.992
Go to Modify → Convert,

532
00:37:52.992 --> 00:37:57.992
then select NURBS to Polygons

533
00:37:57.992 --> 00:38:00.992
Open the options window

534
00:38:02.492 --> 00:38:07.792
Currently, this object is recognized as a NURBS surface,

535
00:38:09.242 --> 00:38:12.042
I am showing it like this

536
00:38:12.042 --> 00:38:16.242
We can know that this is a NURBS object

537
00:38:16.242 --> 00:38:18.242
which can be confirmed in the Outliner

538
00:38:18.242 --> 00:38:20.692
It says, NURBS object

539
00:38:20.692 --> 00:38:22.192
So this is not a polygon

540
00:38:22.792 --> 00:38:27.542
It must be converted before polygon-based editing

541
00:38:27.542 --> 00:38:30.892
First, reset the settings to avoid unintended changes

542
00:38:30.892 --> 00:38:34.442
Now, go to the options, and we get this

543
00:38:34.442 --> 00:38:39.492
We want a quadrilateral mesh, so go for quad

544
00:38:39.492 --> 00:38:42.692
Now, Tessellation method

545
00:38:42.692 --> 00:38:44.742
determines how the surface is divided into polygons

546
00:38:44.742 --> 00:38:48.192
Choosing General allows manual control

547
00:38:48.192 --> 00:38:51.242
Ignore most settings

548
00:38:52.242 --> 00:38:54.292
and focus on Per Span number

549
00:38:54.292 --> 00:38:57.792
of Isoparms for precise control

550
00:38:57.792 --> 00:38:59.492
Also, for the second one,

551
00:38:59.492 --> 00:39:02.542
NURBS has U and V axes

552
00:39:03.642 --> 00:39:05.342
Go for the lower one for U

553
00:39:05.342 --> 00:39:08.592
And for V, go for Per Span # Isoparms

554
00:39:08.592 --> 00:39:12.242
Now we see 3, 3, so this adds three each

555
00:39:12.242 --> 00:39:14.192
Let's apply

556
00:39:14.942 --> 00:39:19.042
Select the NURBS object and click Apply

557
00:39:19.042 --> 00:39:23.242
Now, we have a polygon surface

558
00:39:23.942 --> 00:39:29.392
To avoid confusion, go to Outliner,

559
00:39:29.392 --> 00:39:31.442
and to see the polygon,

560
00:39:31.442 --> 00:39:33.292
let's hide the original NURBS object

561
00:39:33.292 --> 00:39:35.042
by pressing H

562
00:39:35.042 --> 00:39:39.392
Now, we see the converted polygon

563
00:39:39.392 --> 00:39:41.092
This is the polygon

564
00:39:41.492 --> 00:39:45.192
It still retains history

565
00:39:45.192 --> 00:39:49.292
So if I edit the original curves,

566
00:39:49.292 --> 00:39:53.043
the polygon automatically updates

567
00:39:59.743 --> 00:40:04.493
We can select and edit it like this

568
00:40:10.393 --> 00:40:13.893
Now, after finalizing the editing,

569
00:40:14.843 --> 00:40:16.793
Select polygon object

570
00:40:16.793 --> 00:40:20.493
and clear history using Alt + Shift + D

571
00:40:20.493 --> 00:40:22.043
Now that the history is removed,

572
00:40:22.043 --> 00:40:24.893
the polygon remains unaffected

573
00:40:24.893 --> 00:40:26.343
by this curve adjustment

574
00:40:27.693 --> 00:40:32.043
That's an alternative method of polygon modeling

575
00:40:32.043 --> 00:40:37.393
Instead of manually cutting and hsaping

576
00:40:37.393 --> 00:40:39.993
one big object,

577
00:40:39.993 --> 00:40:42.243
we can also use NURBS curves

578
00:40:42.243 --> 00:40:46.593
and covert into polygons

579
00:40:46.593 --> 00:40:47.993
Using this,

580
00:40:47.993 --> 00:40:50.293
we could model this boat

581
00:40:50.293 --> 00:40:54.693
faster and more efficiently

582
00:40:55.293 --> 00:40:58.493
So for modeling projects like for this boat,

583
00:40:58.493 --> 00:41:00.793
this allows us a very fast method

584
00:41:00.793 --> 00:41:03.443
to shape whatever we want

585
00:41:03.443 --> 00:41:06.693
It is widely used in professional workflows too

586
00:41:07.893 --> 00:41:10.443
Back to our boat modeling,

587
00:41:11.793 --> 00:41:17.093
I'll hide the old polygon model

588
00:41:18.793 --> 00:41:23.443
Next, I'll create four curves

589
00:41:23.443 --> 00:41:26.343
by doing what I just showed you

590
00:41:26.343 --> 00:41:28.893
To generate the polygon surface,

591
00:41:29.743 --> 00:41:31.793
I will create four curves

592
00:41:31.793 --> 00:41:35.893
So, I will prepare two profile and two rail curves

593
00:41:35.893 --> 00:41:38.893
and show you from there

594
00:41:38.893 --> 00:41:43.293
I just paused to prepare the curves

595
00:41:43.293 --> 00:41:46.243
I have two rail curves

596
00:41:46.243 --> 00:41:49.843
and three profile curves

597
00:41:49.843 --> 00:41:53.593
Let's apply the Birail command

598
00:41:54.843 --> 00:41:59.993
Go to Surfaces - Birail

599
00:41:59.993 --> 00:42:01.543
Detach the menu

600
00:42:02.293 --> 00:42:05.693
Since we have three profile curves, go for Birail 3+ Tool

601
00:42:05.693 --> 00:42:11.044
Click, one, two, three, press Enter,

602
00:42:11.744 --> 00:42:14.794
then select two rail curves

603
00:42:14.794 --> 00:42:18.544
Now, we generated the NURBS surface

604
00:42:19.444 --> 00:42:24.194
Let me add another point here

605
00:42:24.194 --> 00:42:28.144
If we proceed with modeling directly,

606
00:42:28.144 --> 00:42:32.344
the span intervals are inconsistent,

607
00:42:32.894 --> 00:42:35.644
creating an irregular surface like this

608
00:42:35.644 --> 00:42:37.794
To fix this,

609
00:42:37.794 --> 00:42:39.944
let me teach you this method

610
00:42:39.944 --> 00:42:47.144
Ctrl + A gives you the Attribute Editor

611
00:42:47.144 --> 00:42:48.954
In the second tab,

612
00:42:50.694 --> 00:42:53.694
locate the parameter values,

613
00:42:53.694 --> 00:42:56.744
including UV and Degree values

614
00:42:56.744 --> 00:42:58.744
The Degree value should remain 3,

615
00:42:58.744 --> 00:43:02.744
while the UV values are currently 42 and 5

616
00:43:02.744 --> 00:43:06.644
By setting similar parameter values,

617
00:43:06.644 --> 00:43:08.694
we can achieve a more uniform structure

618
00:43:10.444 --> 00:43:13.644
Go to Surfaces and go down

619
00:43:13.644 --> 00:43:15.494
to find Rebuild

620
00:43:16.744 --> 00:43:20.894
Reset the settings, choose O to # Spans,

621
00:43:20.894 --> 00:43:22.594
set Degree to 3,

622
00:43:22.594 --> 00:43:28.594
and input U = 40,

623
00:43:28.594 --> 00:43:32.544
and V = 5

624
00:43:32.544 --> 00:43:36.794
Clicking Rebuild evens out the surface,

625
00:43:36.794 --> 00:43:39.844
like this

626
00:43:39.844 --> 00:43:44.994
Now, we can proceed with polygon conversion

627
00:43:44.994 --> 00:43:47.894
Let's convert this into polygons

628
00:43:48.744 --> 00:43:51.294
Open Modify, go down

629
00:43:51.294 --> 00:43:55.394
to Convert and NURBS to Polygons

630
00:43:57.044 --> 00:43:59.594
Select Quad Output and choose General

631
00:44:00.744 --> 00:44:03.294
Select Per span # Isoparms

632
00:44:03.294 --> 00:44:06.694
Click on the third option

633
00:44:06.694 --> 00:44:14.094
I think we can use 1 for U

634
00:44:14.094 --> 00:44:22.544
For V, let's try 2

635
00:44:23.394 --> 00:44:26.895
Okay, now close it

636
00:44:26.895 --> 00:44:31.395
Since the NURBS surface

637
00:44:32.795 --> 00:44:35.195
is no longer needed, let's hid it

638
00:44:35.195 --> 00:44:37.395
using H

639
00:44:37.395 --> 00:44:41.945
Now, we have a polygon mesh,

640
00:44:41.945 --> 00:44:44.995
which we will mirror to complete the shape

641
00:44:46.695 --> 00:44:55.645
Go to Edit - Duplicate Special, set Instance,

642
00:44:55.645 --> 00:44:59.795
and enter -1 in the Scale X field

643
00:44:59.795 --> 00:45:03.145
Click Duplicate Special,

644
00:45:03.145 --> 00:45:06.245
and the bottom of the boat is looking more complete

645
00:45:06.245 --> 00:45:12.295
This is a very fast method for the modeling process

646
00:45:13.045 --> 00:45:17.895
With our basic boat body shape completed,

647
00:45:18.495 --> 00:45:23.045
we can not hide the reference images

648
00:45:26.095 --> 00:45:28.245
as well as the NURBS curves

649
00:45:28.795 --> 00:45:32.245
Now, we almost have the complete shape of the boat

650
00:45:32.245 --> 00:45:35.195
Let's disable wireframe mode to confirm

651
00:45:36.045 --> 00:45:37.645
This looks like a boat

652
00:45:37.645 --> 00:45:39.445
Toggle wireframe mode again

653
00:45:40.345 --> 00:45:42.445
Since the boat should be thicker,

654
00:45:42.445 --> 00:45:44.745
select the object,

655
00:45:49.795 --> 00:45:52.795
hold Shift + Right Click

656
00:45:52.795 --> 00:45:56.695
Choose Extrude Face

657
00:45:57.645 --> 00:46:01.795
We can adjust the thickness using this

658
00:46:06.695 --> 00:46:09.995
Let's bring back the reference images

659
00:46:10.995 --> 00:46:15.895
Other parts aren't too difficult

660
00:46:15.895 --> 00:46:19.795
So I will add details

661
00:46:19.795 --> 00:46:23.645
and components to this boat

662
00:46:23.645 --> 00:46:27.795
before I come back in a second

663
00:46:27.795 --> 00:46:30.795
I will pause now and be back with the complete shape

664
00:46:32.845 --> 00:46:35.745
I am finally done building the boat

665
00:46:35.745 --> 00:46:39.745
It took some time, but it is finally ready

666
00:46:39.745 --> 00:46:46.604
Viewing it in wireframe mode, this is how it looks like

667
00:47:16.046 --> 00:47:19.146
This session demonstrated a step-by-step

668
00:47:19.146 --> 00:47:22.646
boat modeling process

669
00:47:24.396 --> 00:47:27.546
In just five lessons, we covered

670
00:47:27.546 --> 00:47:31.546
the fundamentals of polygon modeling

671
00:47:31.546 --> 00:47:33.346
If any parts were unclear,

672
00:47:33.346 --> 00:47:37.146
please re-watch the lessons from the beginning

673
00:47:37.146 --> 00:47:42.196
The more you watch it, the better you will get

674
00:47:42.196 --> 00:47:45.446
This concludes the fifth session

675
00:47:45.446 --> 00:47:47.046
of the Polygon Modeling Course

676
00:47:47.046 --> 00:47:50.646
Let's summarize what we've learned today

677
00:47:50.646 --> 00:47:52.896
Today, we explored various

678
00:47:52.896 --> 00:47:55.346
modeling approaches,

679
00:47:55.346 --> 00:47:58.296
focusing on Birail surface generation

680
00:47:58.296 --> 00:48:01.396
and polygon conversion,

681
00:48:01.396 --> 00:48:03.196
to be more specific

682
00:48:03.446 --> 00:48:06.696
Through these five lessons, we covered

683
00:48:06.696 --> 00:48:09.596
the fundamentals of Autodesk Maya's polygon modeling

684
00:48:09.596 --> 00:48:12.346
While polygon modeling includes many additional

685
00:48:12.346 --> 00:48:14.496
advanced features,

686
00:48:14.496 --> 00:48:16.996
this course focused on establishing

687
00:48:16.996 --> 00:48:20.946
a solid foundation of the concept

688
00:48:20.946 --> 00:48:24.246
Understanding the core principles of polygon modeling

689
00:48:24.246 --> 00:48:26.846
and practicing multiple exercises

690
00:48:26.846 --> 00:48:29.396
will help reinforce your skills

691
00:48:29.396 --> 00:48:30.346
Camera Settings

692
00:48:30.346 --> 00:48:31.346
The lens value affects how the subject is distorted

693
00:48:31.346 --> 00:48:32.346
The human eye sees objects similar to a 55mm lens

694
00:48:32.346 --> 00:48:33.346
A higher lens value makes the subject appear flatter,
while a lower value increases distortion

695
00:48:33.346 --> 00:48:34.346
Background images also vary significantly
based on lens values

696
00:48:34.346 --> 00:48:34.846
Applying Polygon Models

697
00:48:34.846 --> 00:48:35.346
Use polygons to prepare separate images
for the top, front, back, and side of the boat

698
00:48:35.346 --> 00:48:35.846
Create a Template Model to estimate the boat's siz

699
00:48:35.846 --> 00:48:36.346
Use Side Shape → Environment → Create
to generate an Image Plane

700
00:48:36.346 --> 00:48:36.846
Click the folder icon to import the edited reference images

701
00:48:36.846 --> 00:48:37.346
Use Multi-Cut to split the Polygon Cube in half
Adjust the Polygon Cube to match the boat's shape

702
00:48:37.346 --> 00:48:37.846
Understanding Birail

703
00:48:37.846 --> 00:48:38.346
Birail 1 Tool: Select one Profile Curve, then two Rail Curves

704
00:48:38.346 --> 00:48:38.846
Birail 2 Tool: Select two Profile Curves, then two Rail Curves

705
00:48:38.846 --> 00:48:39.346
Birail 3+ Tool: Used when there are three
or more Profile Curves
