00:00:23.719 --> 00:00:26.920
Hello, this is the fourth lecture of Unreal Cinematics

2
00:00:26.920 --> 00:00:29.970
Creating the environment level for cinematics in Unreal

3
00:00:31.070 --> 00:00:34.920
The object of this lecture is to learn and understand

4
00:00:34.920 --> 00:00:37.759
making the environment level for cinematics in Unreal

5
00:00:37.759 --> 00:00:42.639
Then starting now, I'll explain about ways to create the environment

6
00:00:42.639 --> 00:00:45.439
First is collecting reference images

7
00:00:45.439 --> 00:00:49.279
We can't create a cinematic environment right away, from scratch

8
00:00:49.279 --> 00:00:53.240
Therefore, choose a well-made reference

9
00:00:53.240 --> 00:00:56.520
and we need to practice making that reference in Unreal

10
00:00:56.520 --> 00:00:58.570
The image you see here

11
00:00:58.570 --> 00:01:01.160
is a screenshot of a Japanese artist's video on Instagram

12
00:01:01.160 --> 00:01:04.360
We'll try making this environment the same way

13
00:01:04.360 --> 00:01:06.210
First, in the shown image

14
00:01:06.210 --> 00:01:09.320
we need to analyze what sources we need

15
00:01:09.320 --> 00:01:12.919
Analyze the large props first, and once the analysis is over

16
00:01:12.919 --> 00:01:15.119
sequentially analyze the detailed props

17
00:01:15.119 --> 00:01:16.919
and organize the needed sources

18
00:01:16.919 --> 00:01:20.019
When the needed sources go through modeling and texture job

19
00:01:20.019 --> 00:01:21.879
it will take too much time

20
00:01:21.879 --> 00:01:24.229
So search for the environment sources

21
00:01:24.229 --> 00:01:27.360
in the Market Place that Epic Games provides

22
00:01:27.360 --> 00:01:30.239
and purchase sources similar to the corresponding reference

23
00:01:30.239 --> 00:01:32.489
After you obtain the ingredients

24
00:01:32.489 --> 00:01:34.519
let's produce the environment in the project

25
00:01:34.519 --> 00:01:35.969
When you start environment production

26
00:01:35.969 --> 00:01:38.680
the layout arrangement is very important

27
00:01:38.680 --> 00:01:40.880
Therefore, it's good to set the layout of the floor

28
00:01:40.880 --> 00:01:43.680
which can decide the corresponding areas

29
00:01:43.680 --> 00:01:46.130
For me, in order to depict water on the floor

30
00:01:46.130 --> 00:01:48.760
I used the function called blend material

31
00:01:48.760 --> 00:01:50.710
In order to use blend material

32
00:01:50.710 --> 00:01:53.279
the floor mesh has to have lots of vertex

33
00:01:53.279 --> 00:01:55.929
And using the function of vertex painting

34
00:01:55.929 --> 00:01:59.360
you can express the feeling of water of blend material realistically

35
00:01:59.360 --> 00:02:02.260
For this image, blend material was produced

36
00:02:02.260 --> 00:02:04.959
and the water effect was added on the floor surface

37
00:02:04.959 --> 00:02:06.800
Next is creating the sidewalk

38
00:02:06.800 --> 00:02:09.559
I used the source provided by Megascan

39
00:02:09.559 --> 00:02:12.909
In Unreal, with the spline format made with blueprint

40
00:02:12.909 --> 00:02:14.960
the corresponding source can be easily arranged

41
00:02:14.960 --> 00:02:17.960
Expressions of linear lines and curves are possible

42
00:02:17.960 --> 00:02:20.310
However, when path tracing is used

43
00:02:20.310 --> 00:02:24.800
sources of spline type are not rendered on the screen

44
00:02:24.800 --> 00:02:27.300
If you're going to use path tracing

45
00:02:27.300 --> 00:02:30.440
it's possible if you change the spline actor to mesh

46
00:02:30.440 --> 00:02:33.590
A way to change it is shown on the screen

47
00:02:33.590 --> 00:02:36.039
Follow after it, and you'll be able to change it

48
00:02:36.039 --> 00:02:42.679
First, I'll show you how I made the floor

49
00:02:42.679 --> 00:02:45.679
Like this, the floors were first arranged

50
00:02:45.679 --> 00:02:47.839
in a tile form

51
00:02:47.839 --> 00:02:51.389
As for the sidewalk

52
00:02:51.389 --> 00:02:55.080
the mesh was downloaded from Quixel bridge

53
00:02:55.080 --> 00:03:00.999
The downloaded mesh has been mapped as blueprint

54
00:03:00.999 --> 00:03:09.399
And they have been arranged like a sidewalk

55
00:03:09.399 --> 00:03:12.849
As for the floor tile mesh

56
00:03:12.849 --> 00:03:16.479
as you can see, there's a lot of vertex

57
00:03:16.479 --> 00:03:20.930
There's a lot of vertex because

58
00:03:24.800 --> 00:03:30.320
later in Quixel bridge

59
00:03:30.320 --> 00:03:32.920
you can make something called blend material

60
00:03:32.920 --> 00:03:36.620
There, in the texture

61
00:03:36.620 --> 00:03:39.880
you can express the feeling of wet water

62
00:03:39.880 --> 00:03:42.530
To use this function in a detailed way

63
00:03:42.530 --> 00:03:44.720
the tile needs to have a lot of vertices

64
00:03:44.720 --> 00:03:49.520
The water gets expressed based on this vertex

65
00:03:49.520 --> 00:03:54.880
so if there's a small number of vertices, it won't be expressed naturally

66
00:03:56.320 --> 00:04:03.479
Until here, I explained about the floor tile setting method

67
00:04:03.479 --> 00:04:06.479
Now, we'll arrange the large props

68
00:04:06.479 --> 00:04:08.520
just like the reference layout image

69
00:04:08.520 --> 00:04:10.220
The sources used here

70
00:04:10.220 --> 00:04:12.670
were purchased in Unreal Marketplace

71
00:04:12.670 --> 00:04:16.480
The props relatively located towards the back of the layout

72
00:04:16.480 --> 00:04:18.830
don't require a high level of detail

73
00:04:18.830 --> 00:04:22.580
So using simple sources for them

74
00:04:22.580 --> 00:04:25.920
will help with preventing the project from becoming too heavy

75
00:04:25.920 --> 00:04:29.320
The props located in the front of the layout require detail

76
00:04:29.320 --> 00:04:31.520
There are many ways for expressing

77
00:04:31.520 --> 00:04:33.220
but the method I chose this time

78
00:04:33.220 --> 00:04:36.119
uses modeling data expressed in individual pieces

79
00:04:36.119 --> 00:04:38.669
And I've expressed the building by stacking blocks

80
00:04:38.669 --> 00:04:42.069
Like this, I put together each individual prop

81
00:04:42.069 --> 00:04:44.920
and made it look like the layout as much as possible

82
00:04:44.920 --> 00:04:47.120
Just for arranging the layout

83
00:04:47.120 --> 00:04:50.270
it took me about 2 days

84
00:04:50.270 --> 00:04:53.320
When you create your own sources

85
00:04:53.320 --> 00:04:55.760
it will take longer work days than this

86
00:04:55.760 --> 00:04:59.810
Therefore, when you practice cinematic expression in Unreal

87
00:04:59.810 --> 00:05:02.560
rather than doing the modeling and texture job yourself

88
00:05:02.560 --> 00:05:05.359
bringing in the provided sources and expressing them

89
00:05:05.359 --> 00:05:08.239
will save you a lot of time

90
00:05:08.239 --> 00:05:15.989
This time, for the arrangement of large props

91
00:05:15.989 --> 00:05:18.399
I'll show you the method of how I made it

92
00:05:18.399 --> 00:05:23.549
If you see here, in order to make it look similar to the layout

93
00:05:23.549 --> 00:05:24.949
For the front parts

94
00:05:24.949 --> 00:05:29.299
I wanted to make it detailed

95
00:05:29.299 --> 00:05:31.300
So like this

96
00:05:34.120 --> 00:05:36.020
rather than a building made with one piece

97
00:05:36.020 --> 00:05:43.440
I put together various meshes to express the building form

98
00:05:43.440 --> 00:05:46.740
And the relatively less important parts

99
00:05:46.740 --> 00:05:49.140
The parts that are not important in the angle

100
00:05:49.140 --> 00:05:56.220
were arranged in big chunks like this

101
00:05:56.220 --> 00:05:58.070
If you look at the back side

102
00:05:58.070 --> 00:06:04.670
The mesh itself has all the expressions of buildings included

103
00:06:04.670 --> 00:06:07.000
These are normally called Lowpoly buildings

104
00:06:07.000 --> 00:06:11.190
Just like this, in order to arrange the layers on the back

105
00:06:13.279 --> 00:06:20.399
I used Lowpoly buildings

106
00:06:20.399 --> 00:06:26.519
Then after arranging the large props

107
00:06:26.519 --> 00:06:30.869
I added middle sized props

108
00:06:30.869 --> 00:06:37.079
and even smaller sized props on the arrangement

109
00:06:37.160 --> 00:06:41.640
I decorated it like this

110
00:06:41.640 --> 00:06:44.140
There's no correct answer here

111
00:06:44.140 --> 00:06:47.340
For this, look at the reference image

112
00:06:47.340 --> 00:06:52.399
and decide for yourself to what level

113
00:06:52.399 --> 00:06:56.799
you'll decorate the environment, when you're arranging them

114
00:06:56.799 --> 00:07:00.600
So the important part here is

115
00:07:00.600 --> 00:07:04.650
arrange the large props to set the layout first

116
00:07:04.650 --> 00:07:06.850
and then the middle props

117
00:07:06.850 --> 00:07:10.450
and then arrange the smallest props

118
00:07:10.450 --> 00:07:11.959
Going down to the details

119
00:07:11.959 --> 00:07:15.259
This process is very important

120
00:07:15.259 --> 00:07:21.359
so remember the order of this method when you practice

121
00:07:21.359 --> 00:07:25.709
After arranging the front of the layout with assembled building

122
00:07:25.709 --> 00:07:28.880
this is how it looks after arranging the detail props

123
00:07:28.880 --> 00:07:31.780
This is the state without the environment lightings

124
00:07:31.780 --> 00:07:35.280
Unreal's material method that generates its own light

125
00:07:35.280 --> 00:07:37.959
called emissive lighting, is only applied

126
00:07:37.959 --> 00:07:40.459
The project setting is in lumen

127
00:07:40.459 --> 00:07:43.159
and just by arranging the props in emissive

128
00:07:43.159 --> 00:07:45.320
there's still a bit of lighting

129
00:07:45.320 --> 00:07:48.420
However, we can't have lighting with just emissive

130
00:07:48.420 --> 00:07:51.600
we must arrange the light source provided by Unreal

131
00:07:51.600 --> 00:07:54.200
Like the left picture, when only emissive is used

132
00:07:54.200 --> 00:07:57.679
the expression is weak in the cinematic perspective

133
00:07:57.679 --> 00:08:00.029
Here, add Unreal light

134
00:08:00.029 --> 00:08:01.920
and we need to increase the quality

135
00:08:01.920 --> 00:08:03.920
These are the expression methods before adding the lighting effect

136
00:08:03.920 --> 00:08:06.480
and after adding the lighting effect

137
00:08:06.480 --> 00:08:09.080
As you can see, the way of expressing can be freely done

138
00:08:09.080 --> 00:08:13.580
but in order to make the environment closer to a cinematic expression

139
00:08:13.580 --> 00:08:15.920
lighting job is mandatory

140
00:08:15.920 --> 00:08:19.620
This time, for the lighting arrangement

141
00:08:19.620 --> 00:08:22.799
I'll show you the way I did it

142
00:08:22.799 --> 00:08:31.040
At this state, only the emissive is arranged

143
00:08:31.040 --> 00:08:32.590
so it's relatively dark

144
00:08:32.590 --> 00:08:39.159
So first, to show you how to arranged the lighting

145
00:08:39.159 --> 00:08:41.040
Like this

146
00:08:46.950 --> 00:08:51.520
I added a bit of more light elements

147
00:08:51.520 --> 00:08:56.970
Just like I showed on the slides

148
00:08:56.970 --> 00:09:01.070
if only the existing emissive is used for lights

149
00:09:01.070 --> 00:09:03.520
It may look okay up close

150
00:09:03.520 --> 00:09:06.559
but from far away

151
00:09:06.559 --> 00:09:08.659
that fluorescent lamp

152
00:09:08.659 --> 00:09:14.559
That light that provides light doesn't look that strong

153
00:09:14.559 --> 00:09:20.709
The light expression isn't that strong

154
00:09:20.709 --> 00:09:26.800
and it looks relatively dark, so definitely

155
00:09:28.200 --> 00:09:31.200
by arranging lights like this

156
00:09:31.200 --> 00:09:37.950
Showing that there are lights coming out of here

157
00:09:40.100 --> 00:09:43.679
is what I expressed

158
00:09:43.679 --> 00:09:46.999
There's no correct answer to this

159
00:09:47.960 --> 00:09:54.149
If you like this vibe, then you can go with it

160
00:09:54.149 --> 00:09:58.089
But later, when you make the overall environment

161
00:09:58.089 --> 00:10:02.039
only using this, definitely

162
00:10:02.039 --> 00:10:05.639
won't look as pretty later

163
00:10:05.639 --> 00:10:08.239
So always use sources like light

164
00:10:08.239 --> 00:10:11.589
and arrange them in the environment like this

165
00:10:11.589 --> 00:10:17.880
I recommend adding additional lights and arranging them

166
00:10:17.919 --> 00:10:19.869
Next is about setting up the main light

167
00:10:19.869 --> 00:10:22.520
I arranged directional light and sky light

168
00:10:22.520 --> 00:10:24.620
As you can see, I made the image bright because

169
00:10:24.620 --> 00:10:27.470
when expressing the dark parts in Unreal

170
00:10:27.470 --> 00:10:31.440
I wanted to reduce noise as much as possible, so I aimed high

171
00:10:31.440 --> 00:10:34.240
This is my own personal method

172
00:10:34.240 --> 00:10:36.590
I arranged atmosphere and fog

173
00:10:36.590 --> 00:10:39.440
For fog, I used volumetric fog

174
00:10:39.440 --> 00:10:40.790
This is post volume arrangement

175
00:10:40.790 --> 00:10:42.640
These are the adjusted items for post volume

176
00:10:42.640 --> 00:10:45.790
Bloom, Exposure, Chromatic Aberration

177
00:10:45.790 --> 00:10:48.479
Lens Flare, Image Effect, and Color Grading

178
00:10:48.479 --> 00:10:50.279
By arranging post volume

179
00:10:50.279 --> 00:10:53.329
we can see how we can express the cinematics

180
00:10:53.329 --> 00:10:55.729
and based on how we use post volume

181
00:10:55.729 --> 00:10:58.079
whether we can create the cinematic quality or not

182
00:10:58.079 --> 00:10:59.919
gets decided

183
00:10:59.919 --> 00:11:02.369
Here, the results from the test job

184
00:11:02.369 --> 00:11:03.719
will be shown on the computer screen

185
00:11:03.719 --> 00:11:06.440
and we'll review them again

186
00:11:06.440 --> 00:11:10.690
This time, I'll show you how I added the main light and fog

187
00:11:10.690 --> 00:11:15.280
and I'll also show you how I arranged the post volume

188
00:11:15.280 --> 00:11:19.350
Before that, first of all

189
00:11:22.799 --> 00:11:28.179
At the state of emissive arrangement and emissive light added

190
00:11:28.179 --> 00:11:33.179
I first added directional light

191
00:11:33.179 --> 00:11:36.529
As you can see, there isn't much difference

192
00:11:36.529 --> 00:11:41.559
And next, sky light for expressing indirect light

193
00:11:41.559 --> 00:11:45.509
Once I added sky light, as for me

194
00:11:45.509 --> 00:11:48.359
I set the intensity scale to 20

195
00:11:48.359 --> 00:11:51.650
and this is actually a large value in Unreal

196
00:11:51.650 --> 00:11:55.350
But I made it like this in this environment because

197
00:11:55.350 --> 00:11:59.600
this environment is overall dark

198
00:11:59.600 --> 00:12:01.840
It's a dark environment

199
00:12:01.840 --> 00:12:06.960
So later, in post volume, I wanted to lower the exposure value

200
00:12:08.559 --> 00:12:12.609
I was planning to express it by lowering the exposure value

201
00:12:12.609 --> 00:12:16.640
Like I wrote on the slides, first of all

202
00:12:16.640 --> 00:12:20.990
in Unreal, the dark parts have noise

203
00:12:20.990 --> 00:12:24.040
have lots of issues with noise

204
00:12:24.040 --> 00:12:26.440
So in order to reduce that as much as possible

205
00:12:26.440 --> 00:12:29.440
I just made it very bright

206
00:12:29.440 --> 00:12:31.240
Then, in latter adjustments

207
00:12:31.240 --> 00:12:34.390
I would lower the exposure

208
00:12:34.390 --> 00:12:38.000
That's the choice I made

209
00:12:38.000 --> 00:12:40.350
So to continue explaining

210
00:12:40.350 --> 00:12:43.350
I first arranged the sky light like this

211
00:12:43.350 --> 00:12:48.119
And then I added exponential fog

212
00:12:48.119 --> 00:12:53.490
Then finally, I arranged post volume

213
00:12:54.038 --> 00:12:55.738
Just like this

214
00:12:58.440 --> 00:13:01.140
You can see how the look was completed

215
00:13:01.140 --> 00:13:05.750
Now I'll tell you good habits to have

216
00:13:05.750 --> 00:13:08.250
First is organizing the outliner

217
00:13:08.250 --> 00:13:11.900
During the environment job, so many actors get arranged on the level

218
00:13:11.900 --> 00:13:14.300
So if you don't organize the outliner

219
00:13:14.300 --> 00:13:16.080
When you need to make corrections later on

220
00:13:16.080 --> 00:13:17.980
or need to find a particular actor

221
00:13:17.980 --> 00:13:20.430
you will end up wasting time

222
00:13:20.430 --> 00:13:23.980
Therefore, you need to get into the habit of organizing them as you work

223
00:13:23.980 --> 00:13:27.380
And same thing for this, you need to get into the habit of organizing them

224
00:13:27.380 --> 00:13:29.680
In this lecture, in order to show you

225
00:13:29.680 --> 00:13:32.180
what happens if you don't organize

226
00:13:32.180 --> 00:13:34.089
I showed you an instance of a disorganized state

227
00:13:34.089 --> 00:13:38.339
We'll learn about this through the computer screen

228
00:13:38.339 --> 00:13:41.200
Good things to keep in mind during environment work

229
00:13:41.200 --> 00:13:44.150
Those are what I will be explaining right now

230
00:13:44.150 --> 00:13:49.940
Right now, I organized it a bit clumsily

231
00:13:52.520 --> 00:13:55.720
Later, when the environment is made

232
00:13:55.720 --> 00:13:57.670
there will be a lot of actors

233
00:13:57.670 --> 00:14:02.200
Even now, it says that there are 442 actors

234
00:14:02.200 --> 00:14:05.050
If these are arranged without organization

235
00:14:05.050 --> 00:14:06.519
as you can see right now

236
00:14:09.039 --> 00:14:11.489
you will take forever to just find them

237
00:14:11.489 --> 00:14:15.389
So in order to prevent these

238
00:14:15.389 --> 00:14:17.239
The things that you use often

239
00:14:17.239 --> 00:14:20.199
should be placed at the very top

240
00:14:20.199 --> 00:14:23.599
It's good to organize them in a folder at the very top

241
00:14:23.599 --> 00:14:31.190
For the other items as well, if you organize them like this

242
00:14:31.190 --> 00:14:34.540
Later when you need to adjust the environment

243
00:14:34.540 --> 00:14:38.359
it will definitely take less time

244
00:14:38.359 --> 00:14:43.359
And same thing for content browser

245
00:14:43.359 --> 00:14:47.000
If you look here, I used so many things

246
00:14:47.000 --> 00:14:49.400
so the folder is very messy right now

247
00:14:49.400 --> 00:14:52.900
For this too, you may remember it at the time of work

248
00:14:52.900 --> 00:14:56.200
but when you open this project later on

249
00:14:56.200 --> 00:15:00.550
you won't remember what was in which folder

250
00:15:00.550 --> 00:15:03.450
For these too, so that you'll be able to know later on

251
00:15:03.450 --> 00:15:06.479
it will be good to organize them

252
00:15:06.479 --> 00:15:09.229
Now we'll try making the sequence

253
00:15:09.229 --> 00:15:11.079
For camera and animation

254
00:15:11.079 --> 00:15:14.239
set up the corresponding source and do the keyframe job

255
00:15:14.239 --> 00:15:16.589
Then add camera shake in Cine Camera Actor

256
00:15:16.589 --> 00:15:19.339
Add additional characters and add animations

257
00:15:19.339 --> 00:15:23.200
And then sequence animation

258
00:15:23.200 --> 00:15:28.229
I set it up like this

259
00:15:30.559 --> 00:15:32.609
When I play this guy

260
00:15:34.059 --> 00:15:39.419
You can see that it appears like this

261
00:15:39.419 --> 00:15:43.319
In OCIO, color changes can be made between softwares

262
00:15:43.319 --> 00:15:45.269
and in order to use images created in Unreal

263
00:15:45.269 --> 00:15:48.930
in other softwares, you must have this setting

264
00:15:48.930 --> 00:15:51.080
Create OCIO in Unreal

265
00:15:51.080 --> 00:15:53.880
Search for OpenColor in content browser

266
00:15:53.880 --> 00:15:56.200
Move the downloaded OCIO file

267
00:15:56.200 --> 00:16:00.450
move the downloaded OCIO source into the Unreal project folder

268
00:16:00.450 --> 00:16:04.159
The source destination can be set to whatever is preferred by the user

269
00:16:04.159 --> 00:16:05.909
And then when you open the OCIO window

270
00:16:05.909 --> 00:16:09.359
the location where the source can be mapped appears

271
00:16:09.359 --> 00:16:13.479
For this OCIO source, I'll use ACES-1.2

272
00:16:13.479 --> 00:16:14.879
After setting the location

273
00:16:14.879 --> 00:16:18.779
in Color Space and Display View, 'Add Element' was done

274
00:16:18.779 --> 00:16:22.200
by clicking each add button, and index was added

275
00:16:22.200 --> 00:16:23.850
2 were added for color space

276
00:16:23.850 --> 00:16:26.400
and 1 was added for display view

277
00:16:26.400 --> 00:16:29.000
In order to select the item, in index

278
00:16:29.000 --> 00:16:31.300
click the down arrow

279
00:16:31.300 --> 00:16:34.179
And the color setting list that you can choose will appear

280
00:16:34.179 --> 00:16:39.479
Here in Color space, add Utility - Curve - sRGB

281
00:16:39.479 --> 00:16:42.879
and add ACES - ACEScg

282
00:16:42.879 --> 00:16:47.979
In Display view, I added ACES - rec.709

283
00:16:47.979 --> 00:16:52.150
In viewport, in the list that you get after selecting Lit mode

284
00:16:52.150 --> 00:16:55.200
Scroll to the way bottom and go to OCIO display

285
00:16:55.200 --> 00:16:58.150
and you'll see the window where you can select OCIO

286
00:16:58.150 --> 00:17:01.280
Here, you can apply the OCIO that you just created

287
00:17:01.280 --> 00:17:05.730
After selecting Curve-sRGB and ACES-ACESsg

288
00:17:05.730 --> 00:17:07.980
this is the viewport screen you'll see

289
00:17:07.980 --> 00:17:10.780
From the left, it's before applying OCIO

290
00:17:10.780 --> 00:17:15.319
then after applying rec.709, then after applying ACEScg

291
00:17:15.319 --> 00:17:18.419
As you can see there's a huge difference

292
00:17:18.419 --> 00:17:23.760
This time, I'll explain how to apply OCIO

293
00:17:23.760 --> 00:17:26.360
As for me

294
00:17:26.360 --> 00:17:32.030
as I explained, I downloaded the OCIO file

295
00:17:33.199 --> 00:17:36.849
After linking the file, I added the item

296
00:17:36.849 --> 00:17:42.359
Then in viewport, select Lit, then OCIO display

297
00:17:42.359 --> 00:17:47.400
Activate it first

298
00:18:03.040 --> 00:18:04.890
Activate it

299
00:18:05.490 --> 00:18:06.790
Like this

300
00:18:07.640 --> 00:18:11.140
The source I'll read is sRGB

301
00:18:11.140 --> 00:18:14.290
and the exporting source is rec.709

302
00:18:14.290 --> 00:18:17.319
Then this is the viewport screen you'll get

303
00:18:17.319 --> 00:18:22.019
Here, if you change rec.709 to ACEScg, like this

304
00:18:22.969 --> 00:18:29.739
You'll get a completely look from what I intended

305
00:18:29.739 --> 00:18:31.739
As for this setting

306
00:18:31.739 --> 00:18:41.139
as I'll explain later, when making adjustments in the later processes

307
00:18:41.139 --> 00:18:44.339
matching the color space is very important

308
00:18:44.339 --> 00:18:47.410
Then this function will have to be used then

309
00:18:47.410 --> 00:18:51.210
But without those

310
00:18:51.210 --> 00:18:55.210
if you're going to end it in Unreal

311
00:18:55.210 --> 00:18:58.940
you don't necessarily need to use this function

312
00:19:00.239 --> 00:19:05.789
It won't matter to just set the look in the basic settings

313
00:19:05.789 --> 00:19:07.689
Just like the other softwares

314
00:19:07.689 --> 00:19:09.939
in order to match the color space

315
00:19:09.939 --> 00:19:11.959
OCIO setting is mandatory

316
00:19:11.959 --> 00:19:15.709
Then when should OCIO be made and applied?

317
00:19:15.709 --> 00:19:21.040
Actually, you need to set it up as soon as you create the project

318
00:19:21.040 --> 00:19:25.490
That way, you can create the cinematic look that fits that particular color space

319
00:19:25.490 --> 00:19:28.640
In this lecture, in order to show you examples of what happens

320
00:19:28.640 --> 00:19:31.679
when OCIO is worked on later

321
00:19:31.679 --> 00:19:34.579
I tried making the settings after creating the environment

322
00:19:34.579 --> 00:19:36.929
If I don't use other softwares

323
00:19:36.929 --> 00:19:40.959
and I only work in Unreal and make the image sequences

324
00:19:40.959 --> 00:19:43.359
then OCIO setting isn't needed

325
00:19:43.359 --> 00:19:46.609
But even though Unreal is a powerful tool

326
00:19:46.609 --> 00:19:48.909
in order to create a more cinematic quality

327
00:19:48.909 --> 00:19:52.239
you need to understand that you need to use other softwares

328
00:19:52.239 --> 00:19:53.789
The work produced in Unreal

329
00:19:53.789 --> 00:19:55.589
will be further worked on in Davinci Resolve

330
00:19:55.589 --> 00:19:57.339
And this is how to do it

331
00:19:57.339 --> 00:19:58.839
This is the link and the source

332
00:19:58.839 --> 00:20:00.889
This link leads to a video

333
00:20:00.889 --> 00:20:04.540
where Unreal sequence image is sent to Davinci Resolve to work on

334
00:20:04.579 --> 00:20:06.029
In order to derive the corresponding image

335
00:20:06.029 --> 00:20:08.279
we need to carry out the Movie Render Queue setting

336
00:20:08.279 --> 00:20:12.300
Set the image format to png and export the image

337
00:20:12.300 --> 00:20:15.550
Comparing the original video and the video that we just made

338
00:20:15.550 --> 00:20:17.650
although it's not completely different

339
00:20:17.650 --> 00:20:19.900
it has a pretty similar environment

340
00:20:19.900 --> 00:20:22.850
Remember the environment production method I showed you

341
00:20:22.850 --> 00:20:25.250
and please practice it in the same way

342
00:20:25.250 --> 00:20:28.020
And I hope you produce your own awesome environment

343
00:20:28.020 --> 00:20:30.670
In order to give you a lot of information

344
00:20:30.670 --> 00:20:33.339
I did explain pretty fast

345
00:20:33.339 --> 00:20:36.089
Be sure to review it, make it your own

346
00:20:36.089 --> 00:20:38.389
produce your own videos

347
00:20:38.389 --> 00:20:41.083
And I hope you become a great artist

348
00:20:41.083 --> 00:20:43.933
I'll end the lecture here. Thank you

349
00:20:44.425 --> 00:20:45.425
Creating the environment level for cinematics in Unreal
Creating the environment
Way to arrange the layout is important, and layout setting has to start from the floor

350
00:20:45.425 --> 00:20:46.325
In blend material, in order to give the water effect, create the mask map at the part where vertex paint is applied

351
00:20:46.325 --> 00:20:47.275
At the top part of Unreal menu, use the function of Actor -> Merge actors to make it into Mesh, and rendering will be possible even in Path Tracing

352
00:20:47.275 --> 00:20:48.225
For the props relatively in the back, use simple sources to prevent the project from becoming too heavy

353
00:20:48.225 --> 00:20:49.225
Emissive is a lighted state using the Unreal material method that makes its own light

354
00:20:49.225 --> 00:20:50.075
However, only using Emissive isn't enough for lighting, and the light sources provided by Unreal must be arranged

355
00:20:50.075 --> 00:20:51.075
By arranging post volume, the possible cinematic expressions can be viewed
Outliner organization and content browser list organization are needed

356
00:20:51.175 --> 00:20:52.475
Detailed functions of sequencer
Creating the sequencer
Make the settings and keyframes for the corresponding sources such as camera and animations
Add camera shake in Cine Camera Actor
Add additional characters and add animations

357
00:20:52.475 --> 00:20:53.775
Setting Movie Render Queue
OCIO: can change colors between softwares, and in order to work on the image produced by Unreal in other softwares, this setting is mandatory

358
00:20:53.775 --> 00:20:54.975
In order to create OCIO in Unreal, search for OpenColor in content browser
