00:00:27.100 --> 00:00:28.000
Hello

4
00:00:28.000 --> 00:00:31.700
This is Hwang Seong-min, in charge of 3D Blender lectures

5
00:00:31.700 --> 00:00:34.150
In the previous lecture, we modeled

6
00:00:34.150 --> 00:00:37.099
a small space using Blender

7
00:00:37.099 --> 00:00:40.749
Due to time constraints, we kept the space simple

8
00:00:40.749 --> 00:00:43.799
and arranged only a few objects

9
00:00:43.799 --> 00:00:48.000
However, with more practice and
by referencing various samples

10
00:00:48.000 --> 00:00:51.200
 you will be able to create more complex models

11
00:00:51.200 --> 00:00:54.000
In this session, we will focus on

12
00:00:54.000 --> 00:00:57.799
making the modeled space look aesthetically pleasing

13
00:00:57.799 --> 00:01:02.000
This involves setting up proper lighting
and positioning the camera at the right angles

14
00:01:02.000 --> 00:01:05.099
to produce a well-rendered final image

15
00:01:05.099 --> 00:01:07.399
We will cover material creation and application,

16
00:01:07.399 --> 00:01:10.099
lighting, and rendering

17
00:01:10.099 --> 00:01:13.300
The lecture will proceed step by step,

18
00:01:13.300 --> 00:01:16.500
so you can follow along at a comfortable pace

19
00:01:17.130 --> 00:01:21.004
Creating and Applying Materials

20
00:01:22.400 --> 00:01:24.300
Before applying materials,

21
00:01:24.300 --> 00:01:27.037
I will first demonstrate how an object appears

22
00:01:27.037 --> 00:01:29.500
when a material is applied

23
00:01:29.500 --> 00:01:35.300
Selecting an object, I will create a new material

24
00:01:35.300 --> 00:01:41.400
and then adjust the color for better visibility

25
00:01:41.400 --> 00:01:45.000
Although the material and color are applied,

26
00:01:45.000 --> 00:01:49.099
the change does not immediately appear in the viewport

27
00:01:49.099 --> 00:01:53.000
 This is because, in Solid view,

28
00:01:53.000 --> 00:01:56.500
objects are displayed with only basic shading

29
00:01:56.500 --> 00:02:01.000
We need to switch the viewport mode by pressing Z

30
00:02:01.000 --> 00:02:04.300
and change it to Material Preview

31
00:02:04.300 --> 00:02:07.300
After pressing the shortcut for viewport mode, you get

32
00:02:07.300 --> 00:02:12.100
Wireframe, Material Preview, Solid, and Rendered

33
00:02:12.100 --> 00:02:14.399
There are four viewport modes

34
00:02:14.399 --> 00:02:18.199
The first two modes, Wireframe and Solid,

35
00:02:18.199 --> 00:02:21.300
are useful during modeling,

36
00:02:21.300 --> 00:02:24.800
while Material Preview is what we will use now

37
00:02:24.800 --> 00:02:27.637
The Rendered view will be used later

38
00:02:27.637 --> 00:02:29.399
during the rendering process

39
00:02:29.399 --> 00:02:33.699
By switching between Solid and Material Preview modes,

40
00:02:33.699 --> 00:02:38.000
we can immediately observe the differences

41
00:02:38.000 --> 00:02:40.300
To work more efficiently when applying materials,

42
00:02:40.300 --> 00:02:43.500
I will adjust the viewport layout

43
00:02:43.500 --> 00:02:47.000
I will add a new window by dragging

44
00:02:47.000 --> 00:02:50.399
the boundary between the layout and the outliner

45
00:02:50.399 --> 00:02:54.600
This allows for a dual-window setup

46
00:02:54.600 --> 00:02:57.600
Drag to the  left,

47
00:02:57.600 --> 00:03:02.399
and it easily creates a new window

48
00:03:02.399 --> 00:03:06.500
I will set the left window by pressing Z

49
00:03:06.500 --> 00:03:09.300
to Material Preview

50
00:03:09.300 --> 00:03:12.600
and change the right window to Shader Editor

51
00:03:12.600 --> 00:03:15.800
through the header menu

52
00:03:15.800 --> 00:03:19.699
This layout setup is not mandatory

53
00:03:19.699 --> 00:03:23.221
You can adjust it according to your preferences

54
00:03:27.310 --> 00:03:30.199
Now, I will explain the material functions

55
00:03:30.199 --> 00:03:32.899
before applying them to our objects

56
00:03:32.899 --> 00:03:35.600
Before I explain,

57
00:03:35.600 --> 00:03:38.168
I will demonstrate first

58
00:03:38.168 --> 00:03:41.361
so that it helps with the understanding

59
00:03:41.361 --> 00:03:45.399
To illustrate, I will select a wall-mounted light

60
00:03:45.399 --> 00:03:49.000
and remove its current material,

61
00:03:49.000 --> 00:03:52.399
then assign a new one

62
00:03:52.399 --> 00:03:55.949
This action generates a corresponding material node

63
00:03:55.949 --> 00:03:57.800
in the Shader Editor

64
00:03:57.800 --> 00:04:01.000
Blender provides multiple material types,
each with different settings

65
00:04:01.000 --> 00:04:07.000
For this session, we will focus on the Principled BSDF material

66
00:04:07.000 --> 00:04:11.105
and explore its key parameters,
such as Metallic, Roughness, IOR, and Alpha

67
00:04:11.105 --> 00:04:14.600
I will demonstrate how adjusting these values
affects the appearance of the material,

68
00:04:14.600 --> 00:04:19.799
while briefly introducing the remaining settings

69
00:04:19.799 --> 00:04:22.899
The Principled BSDF material

70
00:04:22.899 --> 00:04:26.200
is Blender’s standard shader

71
00:04:26.200 --> 00:04:30.399
based on the Open PBR Surface Shading model

72
00:04:30.399 --> 00:04:33.600
It follows principles similar to those found in materials

73
00:04:33.600 --> 00:04:36.100
used by Disney and other 3D software

74
00:04:36.100 --> 00:04:40.000
The Base Color setting determines the material’s color

75
00:04:40.000 --> 00:04:44.200
By clicking on Base Color, a color picker appears,

76
00:04:44.200 --> 00:04:46.650
allowing for precise adjustments

77
00:04:46.650 --> 00:04:50.700
through direct selection or dragging

78
00:04:50.700 --> 00:04:53.700
To better observe material changes,

79
00:04:53.700 --> 00:04:58.000
I will isolate the object by adjusting the viewport

80
00:04:58.000 --> 00:05:00.600
As soon as the color is modified,

81
00:05:00.600 --> 00:05:03.650
the change is instantly reflected

82
00:05:03.650 --> 00:05:07.100
in Material Preview

83
00:05:07.100 --> 00:05:09.154
The Metallic setting controls

84
00:05:09.154 --> 00:05:11.700
how metallic an object appears

85
00:05:11.700 --> 00:05:15.399
A value closer to 0 means the object
will not have a metallic appearance,

86
00:05:15.399 --> 00:05:18.706
whereas increasing the value toward 1
gives it a more reflective metal-like look

87
00:05:27.131 --> 00:05:31.000
The Roughness parameter determines the surface’s texture

88
00:05:31.000 --> 00:05:34.799
A value near 0 results in sharp, mirror-like reflections,

89
00:05:34.799 --> 00:05:38.200
while a value closer to 1 diffuses reflections,
making the surface appear rougher

90
00:05:38.200 --> 00:05:41.899
When applying materials to our modeled environment,

91
00:05:41.899 --> 00:05:44.499
we will use Roughness

92
00:05:44.499 --> 00:05:47.200
to create softer-looking objects

93
00:05:47.200 --> 00:05:50.299
The IOR setting affects
how light bends when passing through the material

94
00:05:50.299 --> 00:05:56.859
Most objects have an IOR between 1.0 and 4.0

95
00:05:56.859 --> 00:06:00.399
The Alpha setting controls transparency,

96
00:06:00.399 --> 00:06:02.849
with values near 0 making the material fully transparent

97
00:06:02.849 --> 00:06:05.249
and values close to 1 making it opaque

98
00:06:11.700 --> 00:06:14.517
Subsurface scattering is useful for materials

99
00:06:14.517 --> 00:06:16.600
like skin or milk,

100
00:06:16.600 --> 00:06:21.000
giving them a soft, organic appearance

101
00:06:21.000 --> 00:06:23.500
Specular controls the intensity

102
00:06:23.500 --> 00:06:27.100
of reflections on a metallic surface layer

103
00:06:27.100 --> 00:06:30.400
Transmission is used for rendering transparent materials

104
00:06:30.400 --> 00:06:33.500
such as glass or liquids

105
00:06:33.500 --> 00:06:37.100
The Coat parameter functions similarly to Roughness

106
00:06:37.100 --> 00:06:39.031
but adds a clear coat effect,

107
00:06:39.031 --> 00:06:41.600
making the surface appear as if it has a glossy finish

108
00:06:41.600 --> 00:06:45.799
The Sheen setting simulates the tiny fibers seen in fabric,

109
00:06:45.799 --> 00:06:48.699
particularly enhancing reflections

110
00:06:48.699 --> 00:06:54.000
along the edges of cloth, giving it a velvety texture

111
00:06:54.000 --> 00:06:56.350
Emission allows objects to emit light directly from their material,

112
00:06:56.350 --> 00:06:59.600
making them appear as self-illuminating

113
00:06:59.600 --> 00:07:02.300
Thin Film creates a layered effect,

114
00:07:02.300 --> 00:07:04.899
simulating materials that have a thin reflective coating

115
00:07:04.899 --> 00:07:06.815
Adjusting the film's thickness

116
00:07:06.815 --> 00:07:09.380
and refractive index changes how light interacts with the surface

117
00:07:13.399 --> 00:07:17.197
If a created material is no longer needed, it can be removed

118
00:07:17.197 --> 00:07:20.700
Let's learn how to remove it

119
00:07:20.700 --> 00:07:24.300
The usual method is to go in the Shader Editor header

120
00:07:24.300 --> 00:07:26.799
and use the Unlink Data button

121
00:07:26.799 --> 00:07:31.899
It detaches the material from the object

122
00:07:31.899 --> 00:07:36.299
However, the material remains stored and can be reused later

123
00:07:36.299 --> 00:07:38.299
To permanently delete a material,

124
00:07:38.299 --> 00:07:40.899
you could do this instead

125
00:07:40.899 --> 00:07:43.499
Switch the Outliner display mode

126
00:07:43.499 --> 00:07:47.100
to Blender File,

127
00:07:47.100 --> 00:07:51.500
navigate to the Current File section,

128
00:07:51.500 --> 00:07:56.000
and find the materials in the list

129
00:07:56.000 --> 00:08:00.500
These have been something previously created

130
00:08:00.500 --> 00:08:04.700
Select the material we want to remove,

131
00:08:04.700 --> 00:08:06.850
right-click,

132
00:08:06.850 --> 00:08:10.571
and select Delete

133
00:08:10.571 --> 00:08:15.299
The first object to receive a material is the wall

134
00:08:15.299 --> 00:08:19.399
Selecting the connected wall and floor object,

135
00:08:19.399 --> 00:08:23.799
create a new material through the Shader Editor

136
00:08:23.799 --> 00:08:25.749
Then, the currently selected object

137
00:08:25.749 --> 00:08:28.399
will have a new material applied

138
00:08:28.399 --> 00:08:31.000
Each material can be renamed for easier identification,

139
00:08:31.000 --> 00:08:33.809
which is helpful when managing multiple materials

140
00:08:33.809 --> 00:08:35.299
later on

141
00:08:35.299 --> 00:08:37.599
The name can be changed in the header of the Shader Editor

142
00:08:37.599 --> 00:08:39.249
Adjusting the Base Color

143
00:08:39.249 --> 00:08:42.400
in the Material Preview mode immediately updates

144
00:08:42.400 --> 00:08:45.500
the object's appearance in the viewport

145
00:08:45.500 --> 00:08:47.700
I will set the wall color to a beige tone

146
00:08:47.700 --> 00:08:50.099
and, to create a softer look,

147
00:08:50.099 --> 00:08:52.946
increase the Roughness value to 0.8

148
00:09:03.500 --> 00:09:07.299
Next, I will apply a material to the window frame

149
00:09:07.299 --> 00:09:10.299
To view the frame more closely, I will select it

150
00:09:10.299 --> 00:09:13.799
and use the View Selected function to zoom in

151
00:09:13.799 --> 00:09:16.549
After opening the Shader Editor,

152
00:09:16.549 --> 00:09:19.893
I will create a new material and rename it

153
00:09:26.900 --> 00:09:31.400
Adjusting the Base Color to a darker shade can be done

154
00:09:31.400 --> 00:09:34.700
by using the color selection tool

155
00:09:34.700 --> 00:09:36.700
and dragging the scroll bar downward

156
00:09:45.599 --> 00:09:49.900
Finally, I will set the Roughness value to 0.8

157
00:09:49.900 --> 00:09:53.099
I will select both the main frame

158
00:09:53.099 --> 00:09:55.799
and the inner object

159
00:09:55.799 --> 00:09:58.900
Using the shortcut Ctrl+L

160
00:09:58.900 --> 00:10:01.799
opens the Link/Transfer Data menu,

161
00:10:01.799 --> 00:10:04.700
where I will choose Link Materials

162
00:10:04.700 --> 00:10:08.100
This ensures that all selected objects

163
00:10:08.100 --> 00:10:10.400
share the same material

164
00:10:10.400 --> 00:10:13.900
Let me stay here at Link/Transfer Data menu

165
00:10:13.900 --> 00:10:18.099
and talk a little about Link Materials

166
00:10:18.099 --> 00:10:21.099
Link Materials apply the material

167
00:10:21.099 --> 00:10:25.099
from the last selected object to all others

168
00:10:25.099 --> 00:10:28.099
First, select the object that needs the material

169
00:10:28.099 --> 00:10:30.440
Then, select the last object

170
00:10:30.440 --> 00:10:33.200
that already has the desired material applied

171
00:10:33.200 --> 00:10:35.950
Press Ctrl + L

172
00:10:35.950 --> 00:10:38.900
Choose Link Materials

173
00:10:38.900 --> 00:10:41.300
This will apply the material of the last selected object

174
00:10:41.300 --> 00:10:43.200
to the previously selected ones

175
00:10:43.200 --> 00:10:46.600
Make sure you follow the steps correctly,

176
00:10:46.600 --> 00:10:48.099
and it will be helpful

177
00:10:48.099 --> 00:10:50.200
Selecting multiple objects

178
00:10:50.200 --> 00:10:52.343
and then choosing a material from the Shader Editor

179
00:10:52.343 --> 00:10:53.900
might seem like it would apply the material

180
00:10:53.900 --> 00:10:56.829
to all of them at once

181
00:10:56.829 --> 00:11:00.599
However, when removing the existing material

182
00:11:00.599 --> 00:11:02.721
from the window frame bars

183
00:11:02.721 --> 00:11:05.299
and selecting a new material from the material list,

184
00:11:05.299 --> 00:11:08.099
only the last selected object

185
00:11:08.099 --> 00:11:11.700
receives the new material

186
00:11:11.700 --> 00:11:14.424
Because of this, using Link/Transfer Data

187
00:11:14.424 --> 00:11:17.619
is a better approach

188
00:11:17.619 --> 00:11:22.200
Selecting Link/Transfer Data and choosing Link Materials again,

189
00:11:22.200 --> 00:11:27.000
I will apply the material to the window frame

190
00:11:27.000 --> 00:11:30.299
Now, moving on to the bookshelf,

191
00:11:30.299 --> 00:11:33.799
I will select it and open the Shader Editor

192
00:11:33.799 --> 00:11:38.799
Pressing New, I will create a new material and rename it

193
00:11:38.799 --> 00:11:41.049
Then, I will adjust the Base Color

194
00:11:41.049 --> 00:11:43.324
to match the intended look of the scene

195
00:11:50.421 --> 00:11:52.221
After selecting the desired color,

196
00:11:52.221 --> 00:11:55.993
I will modify the Roughness value to 0.8

197
00:11:55.993 --> 00:11:59.472
Once the Roughness is set, I will check the color again

198
00:11:59.472 --> 00:12:02.598
and make any necessary adjustments to refine the appearance

199
00:12:06.079 --> 00:12:08.668
Next, I will select the top section of the bookshelf

200
00:12:08.668 --> 00:12:11.145
and apply a material to it

201
00:12:11.145 --> 00:12:13.995
I will create and rename a new material,

202
00:12:13.995 --> 00:12:16.700
then adjust the Base Color

203
00:12:16.700 --> 00:12:20.799
to complement the rest of the scene

204
00:12:20.799 --> 00:12:23.699
I will try some options

205
00:12:23.699 --> 00:12:26.156
and fine the best color for me

206
00:12:33.188 --> 00:12:35.489
After confirming the color choice,

207
00:12:35.490 --> 00:12:37.590
I will set the Roughness

208
00:12:37.590 --> 00:12:41.700
to 0.8, ensuring consistency across the materials

209
00:12:41.700 --> 00:12:44.822
Select the table legs and apply

210
00:12:44.822 --> 00:12:47.799
the same material as the tabletop

211
00:12:47.799 --> 00:12:52.400
Press Ctrl+L to open the Link/Transfer Data menu

212
00:12:52.400 --> 00:12:55.697
and use the Link Materials function to apply the material

213
00:12:59.000 --> 00:13:03.900
Next, let’s apply the material to the drawer next to the desk

214
00:13:03.900 --> 00:13:08.099
Select the previously applied object materials,

215
00:13:08.099 --> 00:13:12.299
then use the Link/Transfer Data and Link Materials functions

216
00:13:12.299 --> 00:13:16.199
to apply different materials to the exterior, interior,

217
00:13:16.199 --> 00:13:20.500
and handles of the drawer separately

218
00:13:20.500 --> 00:13:23.900
The desk’s material color looks slightly off,

219
00:13:23.900 --> 00:13:28.099
so I will select all its components one by one while holding Shift

220
00:13:28.099 --> 00:13:30.606
and apply the same color as the window frame

221
00:13:34.000 --> 00:13:37.500
Since the repeated color makes it look unnatural, I will revert the change

222
00:13:37.500 --> 00:13:41.299
I also noticed that one of the desk legs
does not have the correct material applied,

223
00:13:41.299 --> 00:13:43.699
so I will select the corresponding material from the material list

224
00:13:43.699 --> 00:13:45.989
and apply it to match the other legs

225
00:13:48.500 --> 00:13:52.500
Next, I will apply materials to the chair
using the previously applied materials

226
00:13:52.500 --> 00:13:55.850
By using the Link/Transfer Data and Link Materials functions,

227
00:13:55.850 --> 00:13:59.500
I will efficiently apply the materials

228
00:14:06.520 --> 00:14:08.461
Now, I will apply material

229
00:14:08.461 --> 00:14:11.331
to the pages of the books on the bookshelf

230
00:14:11.331 --> 00:14:15.440
After selecting the pages, I will create a new material

231
00:14:15.440 --> 00:14:19.589
and choose a slightly darker shade than white

232
00:14:19.589 --> 00:14:23.549
Then, I will set the Roughness value to 0.8

233
00:14:23.549 --> 00:14:26.896
To quickly apply the material to multiple book pages,

234
00:14:26.896 --> 00:14:30.746
I will select all relevant pages and use the Link/Transfer Data

235
00:14:30.746 --> 00:14:32.440
and Link Materials functions

236
00:14:35.470 --> 00:14:39.544
Moving on, I will apply the material to the book covers

237
00:14:39.544 --> 00:14:41.544
irst, I will select one book cover,

238
00:14:41.544 --> 00:14:44.049
create a new material,

239
00:14:44.049 --> 00:14:47.613
and rename it

240
00:14:47.613 --> 00:14:49.055
After selecting the desired color,

241
00:14:49.055 --> 00:14:52.237
I will set the Roughness value to 0.8

242
00:14:52.237 --> 00:14:54.980
Just as I created a red book cover,

243
00:14:54.980 --> 00:14:58.336
I will now create blue, green, and yellow

244
00:14:58.336 --> 00:14:59.881
book cover materials

245
00:15:27.976 --> 00:15:31.126
With four different book cover materials prepared,

246
00:15:31.126 --> 00:15:33.000
I will distribute them evenly

247
00:15:33.000 --> 00:15:36.728
Using the Link/Transfer Data and Link Materials functions,

248
00:15:36.728 --> 00:15:38.659
I will apply the materials to the books

249
00:15:51.549 --> 00:15:55.002
After finishing the materials for the books inside the bookshelf,

250
00:15:55.002 --> 00:15:56.802
I will apply materials

251
00:15:56.802 --> 00:15:59.619
to the books on the desk as well

252
00:15:59.619 --> 00:16:02.019
By reusing the page material from the bookshelf,

253
00:16:02.019 --> 00:16:06.561
I will apply it to the book pages on the desk

254
00:16:06.561 --> 00:16:08.325
To do this quickly,

255
00:16:08.325 --> 00:16:10.368
I will use the Link/Transfer Data

256
00:16:10.368 --> 00:16:13.539
and Link Materials functions

257
00:16:13.539 --> 00:16:16.539
Similarly, I will apply the cover materials using the same process

258
00:16:16.539 --> 00:16:19.299
while adjusting the color distribution for a natural look

259
00:16:19.299 --> 00:16:22.821
Make sure to assign appropriate colors to each

260
00:16:32.681 --> 00:16:34.831
For the final touch,

261
00:16:34.831 --> 00:16:37.020
check the material list

262
00:16:37.020 --> 00:16:39.605
and assign appropriate colors to the book covers

263
00:16:39.605 --> 00:16:41.314
and pages on the desk

264
00:16:46.960 --> 00:16:50.820
Next, I will apply materials to the sofa

265
00:16:50.820 --> 00:16:54.199
I will create a new material in the Shader Editor

266
00:16:54.199 --> 00:16:57.099
and name it accordingly

267
00:16:57.099 --> 00:16:59.549
Let's change the name

268
00:16:59.549 --> 00:17:01.900
and color it beige

269
00:17:01.900 --> 00:17:05.219
The Roughness value will be set to 0.8

270
00:17:05.219 --> 00:17:09.939
For the rest of the sofa, I will generate new materials, rename them,

271
00:17:09.939 --> 00:17:13.099
and select similar beige shades

272
00:17:13.099 --> 00:17:16.056
The Roughness value will be set to 0.8 for all

273
00:17:24.081 --> 00:17:26.859
For the sofa legs, I will apply a wood-like texture

274
00:17:26.859 --> 00:17:29.109
by reusing a previously assigned material

275
00:17:29.109 --> 00:17:32.900
Using the Link/Transfer Data and Link Materials functions,

276
00:17:32.900 --> 00:17:35.217
I will quickly apply the material to all sofa legs

277
00:17:49.390 --> 00:17:52.739
Now, I will apply materials to the table

278
00:17:52.739 --> 00:17:56.020
First, I will create a new material

279
00:17:56.020 --> 00:17:59.020
in the Shader Editor,

280
00:17:59.020 --> 00:18:02.699
rename it, and keep the default base color

281
00:18:02.699 --> 00:18:05.260
The Roughness value will be set to 0.5,

282
00:18:05.260 --> 00:18:07.110
and the Alpha value will be set to 0.25

283
00:18:07.110 --> 00:18:09.884
to create a slightly transparent table

284
00:18:23.859 --> 00:18:27.009
I will also adjust any areas where the sofa’s Roughness value

285
00:18:27.009 --> 00:18:29.660
was not properly set to 0.8

286
00:18:29.660 --> 00:18:34.219
before moving on to defining the table leg materials

287
00:18:34.219 --> 00:18:38.109
I will create a new material and rename it accordingly

288
00:18:48.900 --> 00:18:53.300
To achieve a metallic appearance,
I will set the base color’s Metallic value to 0.6

289
00:18:53.300 --> 00:18:57.020
and the Roughness value to 0.2

290
00:18:57.020 --> 00:18:59.819
To prevent the legs from looking too starkly white,

291
00:18:59.819 --> 00:19:03.660
I will slightly darken the color

292
00:19:03.660 --> 00:19:06.099
Finally, I will select the remaining table legs

293
00:19:06.099 --> 00:19:09.939
and use the Link/Transfer Data and Link Materials functions

294
00:19:09.939 --> 00:19:11.536
to apply the same material

295
00:19:30.900 --> 00:19:34.420
Next, I will apply materials to the TV

296
00:19:34.420 --> 00:19:37.339
In the Shader Editor, I will create a new material

297
00:19:37.339 --> 00:19:40.339
and rename it

298
00:19:40.339 --> 00:19:42.619
The base color will be adjusted to a dark shade,

299
00:19:42.619 --> 00:19:45.280
and the Roughness value will be set to 0.8

300
00:19:52.979 --> 00:19:55.229
For the TV screen glass,

301
00:19:55.229 --> 00:19:57.219
I will simulate a turned-off screen

302
00:19:57.219 --> 00:19:59.495
by setting the color to black

303
00:19:59.495 --> 00:20:02.216
and the Roughness value to 0.8

304
00:20:12.238 --> 00:20:16.600
For the TV stand, I will apply the same material
used for the drawer handles

305
00:20:16.600 --> 00:20:22.200
by utilizing the Link/Transfer Data and Link Materials functions

306
00:20:22.200 --> 00:20:25.400
The legs of the TV will be assigned the same material as the TV body,

307
00:20:25.400 --> 00:20:30.122
also using the Link/Transfer Data and Link Materials functions

308
00:20:43.599 --> 00:20:48.400
Next, I will apply materials to the picture frames hanging on the wall

309
00:20:48.400 --> 00:20:52.599
Using the Link/Transfer Data and Link Materials functions,

310
00:20:52.599 --> 00:20:57.489
I will assign the book page material to the inner part of the frame
and the table material to the outer frame

311
00:21:12.757 --> 00:21:14.887
Moving on to the wall-mounted lights,

312
00:21:14.887 --> 00:21:18.089
I will apply materials to them

313
00:21:18.089 --> 00:21:19.789
First, I will select one of the lights

314
00:21:19.789 --> 00:21:23.599
and create a new material in the Shader Editor

315
00:21:23.599 --> 00:21:27.614
I will rename it and set the color to a dark shade

316
00:21:34.900 --> 00:21:39.050
I will then adjust the Metallic value to 0.8

317
00:21:39.050 --> 00:21:41.900
and the Roughness value to 0.25

318
00:21:41.900 --> 00:21:43.900
The remaining three lights

319
00:21:43.900 --> 00:21:47.400
will be assigned the same material

320
00:21:47.400 --> 00:21:50.199
To do this efficiently, I will first select the three other lights,

321
00:21:50.199 --> 00:21:54.400
then select the already assigned light last,

322
00:21:54.400 --> 00:21:58.100
press Ctrl + L,

323
00:21:58.100 --> 00:22:01.400
and choose Link Materials to apply the same material to all of them

324
00:22:01.400 --> 00:22:05.800
The picture frames placed on the drawer

325
00:22:05.800 --> 00:22:09.500
will be assigned the same material as the wall-mounted frames

326
00:22:09.500 --> 00:22:11.972
using the Link/Transfer Data and Link Materials functions

327
00:22:27.798 --> 00:22:31.699
Next, I will apply material to the desk

328
00:22:31.699 --> 00:22:35.100
The lower support and columns will receive
the same material as the table legs

329
00:22:35.100 --> 00:22:39.300
through the Link/Transfer Data and Link Materials functions,

330
00:22:39.300 --> 00:22:43.399
while the main body of the desk will be assigned a new material

331
00:22:43.399 --> 00:22:47.100
In the Shader Editor, I will create a new material, rename it,

332
00:22:47.100 --> 00:22:49.370
and change the color to gray

333
00:22:53.699 --> 00:22:55.899
I will then set the Roughness value to 0.8

334
00:22:55.899 --> 00:22:58.452
and the Alpha value to 0.25

335
00:23:10.899 --> 00:23:14.800
Now, I will apply materials to the tiles

336
00:23:14.800 --> 00:23:17.804
Since the tiles were modeled as a single grid-shaped object

337
00:23:17.804 --> 00:23:19.919
during the modeling stage,

338
00:23:19.919 --> 00:23:22.367
I can easily apply materials

339
00:23:22.367 --> 00:23:25.300
in a checkerboard pattern

340
00:23:25.300 --> 00:23:30.800
First, I will select one tile and create a new material in the Shader Editor

341
00:23:30.800 --> 00:23:33.199
After renaming it,

342
00:23:33.199 --> 00:23:36.800
I will adjust the color to a slightly darker shade than white

343
00:23:36.800 --> 00:23:40.300
and set the Roughness value to 0.8

344
00:23:40.300 --> 00:23:44.000
Then, I will duplicate the tile material

345
00:23:44.000 --> 00:23:46.406
and change only the color

346
00:24:14.699 --> 00:24:18.399
Finally, I will apply material to the cup

347
00:24:18.399 --> 00:24:21.899
In the Shader Editor, I will create a new material,

348
00:24:21.899 --> 00:24:23.453
rename it,

349
00:24:32.000 --> 00:24:35.600
and adjust the color to be slightly darker than the default

350
00:24:35.600 --> 00:24:38.406
The Roughness value will be set to 0.8

351
00:24:43.045 --> 00:24:46.777
Lighting Types and Placement

352
00:24:47.299 --> 00:24:51.000
Now, I will explain lighting

353
00:24:51.000 --> 00:24:55.250
In Blender, there are four main types of lights:
Point Light, Sun Light,

354
00:24:55.250 --> 00:24:59.600
Spot Light, and Area Light

355
00:24:59.600 --> 00:25:02.100
After covering their basic properties,

356
00:25:02.100 --> 00:25:06.600
I will place lights in the scene

357
00:25:06.600 --> 00:25:08.950
To explain lighting,

358
00:25:08.950 --> 00:25:12.600
I have set up a simple scene

359
00:25:12.600 --> 00:25:16.500
I will go over each light type while demonstrating them on screen

360
00:25:16.500 --> 00:25:18.550
Point Light

361
00:25:18.550 --> 00:25:21.200
emits light evenly in all directions,

362
00:25:21.200 --> 00:25:24.700
similar to an indoor lightbulb

363
00:25:53.368 --> 00:25:56.618
Sun Light projects light in a single direction

364
00:25:56.618 --> 00:25:58.730
from a far distance, simulating sunlight

365
00:25:58.730 --> 00:26:01.888
Because it represents the sun,

366
00:26:01.888 --> 00:26:04.988
even a low strength value

367
00:26:04.988 --> 00:26:09.160
produces a bright effect, making it ideal for outdoor lighting

368
00:26:09.160 --> 00:26:11.369
The Sun Light’s angle can be adjusted to change

369
00:26:11.369 --> 00:26:13.477
the direction of the light,

370
00:26:13.477 --> 00:26:17.626
but moving its position will not affect the rendering

371
00:26:37.406 --> 00:26:42.934
Spot Light emits light in a cone shape toward a specific direction

372
00:26:42.934 --> 00:26:47.360
It works similarly to a flashlight or a car’s headlights

373
00:27:33.838 --> 00:27:37.488
Area Light is used for light that spreads

374
00:27:37.488 --> 00:27:39.625
from a surface

375
00:27:39.625 --> 00:27:43.902
It creates soft-edged shadows and is useful for simulating objects

376
00:27:43.902 --> 00:27:46.252
that emit light, such as

377
00:27:46.252 --> 00:27:48.611
TV screens or fluorescent lamps

378
00:27:48.611 --> 00:27:50.519
emitting LED light

379
00:28:12.022 --> 00:28:14.472
Let's cover a fundamental setup widely used in film and photography,

380
00:28:14.472 --> 00:28:17.933
which is three-point lighting

381
00:28:17.933 --> 00:28:21.319
This method involves placing three lights

382
00:28:21.319 --> 00:28:23.962
and is one of the most popular methods

383
00:28:23.962 --> 00:28:27.873
As for the name goes, there are three light sources here

384
00:28:27.873 --> 00:28:31.556
The first light is the Key Light, the primary light source

385
00:28:31.556 --> 00:28:34.806
that determines overall brightness

386
00:28:34.806 --> 00:28:36.626
and shadow direction

387
00:28:36.626 --> 00:28:40.319
The second is the Fill Light,

388
00:28:40.319 --> 00:28:44.685
which reduces contrast by illuminating darker areas of the subject

389
00:28:44.685 --> 00:28:47.497
Since the fill light is responsible for illuminating the darkest areas,

390
00:28:47.497 --> 00:28:51.527
it reduces the contrast between the brightest and darkest

391
00:28:51.527 --> 00:28:53.933
The third light is the backlight,

392
00:28:53.933 --> 00:28:57.873
which shines from behind the subject

393
00:28:57.873 --> 00:29:02.200
Because it illuminates from
the opposite direction of the camera’s perspective,

394
00:29:02.200 --> 00:29:05.388
it enhances the object’s silhouette

395
00:29:05.388 --> 00:29:07.288
By emphasizing the outline,

396
00:29:07.288 --> 00:29:10.022
the backlight helps create a more three-dimensional effect,

397
00:29:10.022 --> 00:29:14.200
making it an essential element in 3D space composition

398
00:29:14.200 --> 00:29:16.950
Although I will not be applying

399
00:29:16.950 --> 00:29:20.358
a full three-point lighting setup in this particular scene,

400
00:29:20.358 --> 00:29:23.258
I wanted to introduce the concept
since it serves as a fundamental guideline

401
00:29:23.258 --> 00:29:24.685
for placing lights effectively

402
00:29:24.685 --> 00:29:28.085
Before setting up the lights,
I will switch back to a single view,

403
00:29:28.085 --> 00:29:30.160
similar to the modeling workspace,

404
00:29:30.160 --> 00:29:33.560
and prepare a wide floor area to ensure

405
00:29:33.560 --> 00:29:36.794
that the lighting appears correctly in the final render

406
00:29:36.794 --> 00:29:41.636
Press Shift+A to bring up the Add shortcut and add a cube

407
00:29:41.636 --> 00:29:45.633
Then, in the Properties panel, change the Scale values

408
00:29:45.633 --> 00:29:47.853
for X, Y, and Z to 3

409
00:29:47.853 --> 00:29:50.603
Next, press the Tab key

410
00:29:50.603 --> 00:29:52.992
to switch to Edit Mode

411
00:29:52.992 --> 00:29:56.542
Using the Delete shortcut X key,

412
00:29:56.542 --> 00:29:58.893
remove three faces of the cube

413
00:29:58.893 --> 00:30:02.193
Then, switch back to Object Mode

414
00:30:02.193 --> 00:30:06.675
and adjust its position and size as needed

415
00:30:06.675 --> 00:30:11.249
Switch back to Edit Mode, select the cube’s edges,

416
00:30:11.249 --> 00:30:14.399
nd press Ctrl+B to apply a Bevel

417
00:30:14.399 --> 00:30:16.744
to split the edges

418
00:30:16.744 --> 00:30:20.378
Set the Segment value to 5

419
00:30:20.378 --> 00:30:23.428
Finally, right-click

420
00:30:23.428 --> 00:30:26.200
and select Shade Smooth to smooth out the edges

421
00:30:35.200 --> 00:30:38.700
Now, switch the view mode using the Z shortcut

422
00:30:38.700 --> 00:30:41.041
and select Rendered View

423
00:30:41.041 --> 00:30:42.891
Add a Point Light

424
00:30:42.891 --> 00:30:44.408
and position it accordingly

425
00:31:06.760 --> 00:31:09.202
 Open the Properties panel

426
00:31:09.202 --> 00:31:11.760
and navigate to the light settings

427
00:31:11.760 --> 00:31:15.160
to adjust the Power and Radius values

428
00:31:24.360 --> 00:31:26.257
Create an additional Point Light

429
00:31:26.257 --> 00:31:28.360
and position it

430
00:31:28.360 --> 00:31:30.760
Turn off the Shade function

431
00:31:30.760 --> 00:31:33.959
and modify the Power and Radius values to suit the scene

432
00:32:08.396 --> 00:32:10.846
Next, add an Area Light and position it

433
00:32:10.846 --> 00:32:15.107
to simulate light coming in through the window

434
00:32:15.107 --> 00:32:20.404
Adjust the Size to 3m, refine the positioning,

435
00:32:20.404 --> 00:32:24.204
and tweak the light color

436
00:32:24.204 --> 00:32:27.385
to create a warm atmosphere

437
00:33:23.778 --> 00:33:27.560
Rendering in Blender

438
00:33:27.960 --> 00:33:31.960
We will now cover rendering settings

439
00:33:31.960 --> 00:33:35.287
There are two main rendering methods available

440
00:33:35.287 --> 00:33:37.919
One is Eevee rendering

441
00:33:37.919 --> 00:33:40.826
Eevee is a real-time rendering engine

442
00:33:40.826 --> 00:33:43.137
focused on speed

443
00:33:43.137 --> 00:33:45.887
It does not calculate each light direction precisely

444
00:33:45.887 --> 00:33:48.087
but instead uses an approximate rendering method,

445
00:33:48.087 --> 00:33:51.206
skipping some calculations

446
00:33:51.206 --> 00:33:56.493
This makes it much faster but less accurate in terms of realism

447
00:33:56.493 --> 00:33:59.305
Next is Cycles rendering

448
00:33:59.305 --> 00:34:03.919
Cycles is a ray-tracing-based rendering engine

449
00:34:03.919 --> 00:34:07.019
It calculates light directions and intensity

450
00:34:07.019 --> 00:34:09.078
in a physically accurate way,

451
00:34:09.078 --> 00:34:12.078
producing high-quality results

452
00:34:12.078 --> 00:34:13.978
However, it requires much more computing power,

453
00:34:13.978 --> 00:34:16.880
making the rendering process slower

454
00:34:16.880 --> 00:34:20.280
Cycles rendering allows you to choose

455
00:34:20.280 --> 00:34:25.296
between using the CPU or GPU for computation

456
00:34:25.296 --> 00:34:28.546
When rendering in Camera view,

457
00:34:28.546 --> 00:34:30.870
you can preview the output before finalizing your work

458
00:34:30.870 --> 00:34:34.126
So let's set the camera first

459
00:34:34.126 --> 00:34:37.244
To begin, add a camera

460
00:34:37.244 --> 00:34:39.433
by pressing Shift + A

461
00:34:39.433 --> 00:34:42.033
You can move the camera using the G shortcut

462
00:34:42.033 --> 00:34:44.334
or adjust its angle with R,

463
00:34:44.334 --> 00:34:47.374
to set up the camera,

464
00:34:47.374 --> 00:34:50.839
but setting it up while in Camera view is more convenient

465
00:34:50.839 --> 00:34:54.156
So let's switch to Camera view

466
00:34:54.156 --> 00:34:57.056
To switch to Camera view,

467
00:34:57.056 --> 00:34:59.839
press the ~ key

468
00:34:59.839 --> 00:35:04.800
If you move the view with your mouse or keyboard,

469
00:35:04.800 --> 00:35:08.800
it will switch back to Perspective view

470
00:35:08.800 --> 00:35:12.200
To lock the Camera view while making adjustments,

471
00:35:12.200 --> 00:35:14.800
you need to set an option

472
00:35:14.800 --> 00:35:17.100
If sidebar is not enabled,

473
00:35:17.100 --> 00:35:20.800
first enable the sidebar with N

474
00:35:20.800 --> 00:35:25.106
Then, under the View tab,

475
00:35:25.106 --> 00:35:27.756
check Camera to View

476
00:35:27.756 --> 00:35:30.948
in the Lock menu

477
00:35:30.948 --> 00:35:35.760
Switch to Camera View using the ~ shortcut

478
00:35:35.760 --> 00:35:38.978
If you move the view using the mouse or keyboard,

479
00:35:38.978 --> 00:35:40.978
it will remain in Camera View

480
00:35:40.978 --> 00:35:43.760
and will not switch back to Perspective View

481
00:35:43.760 --> 00:35:46.760
At this stage, I will proceed with

482
00:35:46.760 --> 00:35:48.265
setting up the camera for rendering

483
00:35:54.162 --> 00:35:56.162
Rendering offers various options

484
00:35:56.162 --> 00:35:59.627
to produce different output styles,

485
00:35:59.627 --> 00:36:01.927
but capturing the exact scene visible

486
00:36:01.927 --> 00:36:05.333
in Camera View is straightforward

487
00:36:05.333 --> 00:36:08.759
In the Properties panel, navigate to the Render tab,

488
00:36:08.759 --> 00:36:12.769
adjust a few basic settings, and then proceed with rendering

489
00:36:12.769 --> 00:36:16.502
There are many available settings, but to achieve high-quality results,

490
00:36:16.502 --> 00:36:19.690
I will switch the Render Engine to Cycles

491
00:36:19.690 --> 00:36:22.956
and set the Device to GPU

492
00:36:22.956 --> 00:36:25.456
In the Sampling section under Render Settings,

493
00:36:25.456 --> 00:36:28.114
I will configure the Max Samples to 2048

494
00:36:28.114 --> 00:36:29.738
before starting the rendering process.

495
00:36:40.402 --> 00:36:43.640
The shortcut key for rendering is F12

496
00:36:43.640 --> 00:36:45.540
Alternatively, in the Top Bar Menu,

497
00:36:45.540 --> 00:36:48.887
clicking Render > Render Image

498
00:36:48.887 --> 00:36:51.127
will render the current

499
00:36:51.127 --> 00:36:53.462
Camera View scene

500
00:36:53.462 --> 00:36:55.512
Once rendering begins,

501
00:36:55.512 --> 00:36:58.462
the image may initially appear noisy

502
00:36:58.462 --> 00:37:02.482
In the Status Bar, you can check the Sample Count,

503
00:37:02.482 --> 00:37:05.310
which shows the progress out

504
00:37:05.310 --> 00:37:07.402
of 2048 total samples

505
00:37:07.402 --> 00:37:10.164
Once all 2048 samples are completed,

506
00:37:10.164 --> 00:37:12.464
a clean and fully rendered image

507
00:37:12.464 --> 00:37:15.095
will be displayed

508
00:37:15.095 --> 00:37:18.907
To save the rendered result, go to the Top Menu,

509
00:37:18.907 --> 00:37:23.244
click Image > Save As, and choose a save location

510
00:37:23.244 --> 00:37:25.644
The Left and Center Panels

511
00:37:25.644 --> 00:37:28.016
allow selecting the file path,

512
00:37:28.016 --> 00:37:31.317
while the Right Panel provides options

513
00:37:31.317 --> 00:37:33.887
to adjust image settings before saving

514
00:37:33.887 --> 00:37:38.095
Let's continue with the default setting

515
00:37:38.095 --> 00:37:41.295
By default, the image will be saved as a PNG file

516
00:37:41.295 --> 00:37:45.026
in the specified directory

517
00:37:45.026 --> 00:37:47.956
This method allows exporting the rendered view

518
00:37:47.956 --> 00:37:52.303
in different formats for further use

519
00:37:52.303 --> 00:37:55.953
In this session, we covered creating

520
00:37:55.953 --> 00:37:58.937
and applying materials, lighting, and rendering in Blender

521
00:37:58.937 --> 00:38:01.637
As you may have noticed during practice,

522
00:38:01.637 --> 00:38:03.600
lighting plays a crucial role

523
00:38:03.600 --> 00:38:08.313
in enhancing depth and realism

524
00:38:08.313 --> 00:38:10.263
By practicing with various exercises

525
00:38:10.263 --> 00:38:12.966
using the techniques learned today,

526
00:38:12.966 --> 00:38:16.768
3D rendering skills can be further improved

527
00:38:16.768 --> 00:38:20.966
Let’s summarize what we learned in this session

528
00:38:20.966 --> 00:38:21.772
