00:00:02,960 --> 00:00:09,880
Redshift interface and Objects

2
00:00:09,880 --> 00:00:14,000
In this lesson I will show you
where to find Redshift menus and objects

3
00:00:14,000 --> 00:00:16,799
and I will talk about
each one individually.

4
00:00:16,799 --> 00:00:20,559
Let's take a look.

5
00:00:20,559 --> 00:00:23,360
I have experienced
many different render engines

6
00:00:23,360 --> 00:00:26,479
and, honestly, Redshift is my favorite

7
00:00:26,479 --> 00:00:31,159
because it is very fast
and also very easy to work with.

8
00:00:31,159 --> 00:00:33,720
Once you install Redshift in Cinema 4D,

9
00:00:33,720 --> 00:00:39,080
you will have this menu here
and everything will be here.

10
00:00:39,080 --> 00:00:42,240
It's not complicated.

11
00:00:42,240 --> 00:00:46,639
To make this lesson more interesting,
I have created this setup

12
00:00:46,639 --> 00:00:48,959
and I will show you how I made that.

13
00:00:48,959 --> 00:00:52,520
But before that,
I recommend creating your own layout

14
00:00:52,520 --> 00:00:56,319
when you are working with Redshift.

15
00:00:56,319 --> 00:00:57,840
Because I have one monitor,

16
00:00:57,840 --> 00:01:00,639
I'd like just to put that here
in the same monitor.

17
00:01:00,639 --> 00:01:05,720
Redshift, click on Redshift RenderView,

18
00:01:05,720 --> 00:01:09,000
and then I can grab this

19
00:01:09,000 --> 00:01:13,959
and dock this window
somewhere like here.

20
00:01:13,959 --> 00:01:16,519
I can also change this size

21
00:01:16,519 --> 00:01:22,239
to make sure it is getting
the best crop for me, for this layout.

22
00:01:22,239 --> 00:01:27,080
If I click on this icon
and go to Output,

23
00:01:27,080 --> 00:01:33,680
and I change this
to something like 540 and 960,

24
00:01:33,680 --> 00:01:38,199
now you can see
I have this object here,

25
00:01:38,199 --> 00:01:41,720
and if I just press
this Play button here,

26
00:01:41,720 --> 00:01:43,879
I can see my object.

27
00:01:43,879 --> 00:01:47,879
REDSHIFT
Interface

28
00:01:47,879 --> 00:01:51,400
Here I can access the preferences.

29
00:01:51,400 --> 00:01:57,360
This will not a separate thing
from Cinema 4D preferences.

30
00:01:57,360 --> 00:02:01,000
Thankfully, Redshift works very well

31
00:02:01,000 --> 00:02:06,040
with most of the native Cinema 4D
objects and parameters.

32
00:02:06,040 --> 00:02:09,119
If I click on this, it opens up
Cinema 4D preferences,

33
00:02:09,119 --> 00:02:10,520
but it shows me Redshift.

34
00:02:10,520 --> 00:02:16,880
You can see your graphic cards
and all the options here.

35
00:02:16,880 --> 00:02:19,279
I would like to bring in one light

36
00:02:19,279 --> 00:02:23,679
and start a real-time rendering
done that way.

37
00:02:23,679 --> 00:02:27,279
I'll talk about each individual element.

38
00:02:27,279 --> 00:02:30,759
Here, in Lights, I will bring
one Area Light.

39
00:02:30,759 --> 00:02:37,160
I will talk about each individual light
in the next lesson,

40
00:02:37,160 --> 00:02:43,199
but for now, I can just grab and move it
and put it somewhere like here.

41
00:02:43,199 --> 00:02:49,960
Let me scale the light a little bit
and put it somewhere like here.

42
00:02:49,960 --> 00:02:52,479
Now, if I press this Play button,

43
00:02:52,479 --> 00:02:58,679
as you see,
this is a real-time rendering.

44
00:02:58,679 --> 00:03:05,240
I can just very easily
rotate around the Viewport

45
00:03:05,240 --> 00:03:10,240
and see the result in real time.

46
00:03:10,240 --> 00:03:14,800
I already have a beautiful
bouncing effect of the light

47
00:03:14,800 --> 00:03:17,639
in between all these objects.

48
00:03:17,639 --> 00:03:21,080
This is because I already have turned on

49
00:03:21,080 --> 00:03:27,080
the Global Illumination in my rendering.
What is Global Illumination?

50
00:03:27,080 --> 00:03:33,320
If I open up Render Settings here
and switch to Redshift

51
00:03:33,320 --> 00:03:39,000
and click on Redshift,
you can see I have a GI tab here.

52
00:03:39,000 --> 00:03:42,000
By default it's set to None.

53
00:03:42,000 --> 00:03:45,479
If I change them to None,
now you can see the difference.

54
00:03:45,479 --> 00:03:47,279
I have very harsh shadows

55
00:03:47,279 --> 00:03:52,080
and I don't see
any bouncing of the light.

56
00:03:52,080 --> 00:03:54,679
Basically when you have a light source

57
00:03:54,679 --> 00:03:58,880
it emits some light rays
onto the object,

58
00:03:58,880 --> 00:04:05,000
and then it will rebounce again
and rebounce again a million times.

59
00:04:05,000 --> 00:04:09,720
That's why you get
that beautiful global illumination

60
00:04:09,720 --> 00:04:14,199
which is called GI in 3D rendering.

61
00:04:14,199 --> 00:04:17,679
I always recommend adding some GI.

62
00:04:17,679 --> 00:04:19,920
It can be one of these objects,

63
00:04:19,920 --> 00:04:24,000
but I recommend using Brute Force
for the primary engine,

64
00:04:24,000 --> 00:04:27,760
and you can use Brute Force as well
for the secondary

65
00:04:27,760 --> 00:04:33,399
or Irradiance Point Cloud.
It depends on your scene.

66
00:04:33,399 --> 00:04:37,359
Most of the time, Irradiance Point Cloud
mixed with Brute Force

67
00:04:37,359 --> 00:04:40,760
gives you a faster and cleaner result.

68
00:04:40,760 --> 00:04:44,640
For now I just put it on Brute Force.

69
00:04:44,640 --> 00:04:48,519
You can see again
light has too much emission,

70
00:04:48,519 --> 00:04:52,959
so maybe I can just select the light,
go to General,

71
00:04:52,959 --> 00:05:00,000
and here I can change this intensity
to something like 40.

72
00:05:00,000 --> 00:05:05,040
You can also scale the lights,
and when you scale the light,

73
00:05:05,040 --> 00:05:10,519
you get more intensity,
but the shadows will be softer.

74
00:05:10,519 --> 00:05:14,640
And to compensate that,
I will put this in a lower number.

75
00:05:14,640 --> 00:05:18,519
As you see,
I have this beautiful result.

76
00:05:18,519 --> 00:05:23,760
REDSHIFT
Objects

77
00:05:23,760 --> 00:05:25,839
In Redshift and Objects

78
00:05:25,839 --> 00:05:28,679
I have one object
called Redshift BakeSet.

79
00:05:28,679 --> 00:05:32,720
This helps you to bake your textures.

80
00:05:32,720 --> 00:05:37,320
If I bring in one Redshift Environment,
you don't see any result.

81
00:05:37,320 --> 00:05:41,760
Basically it creates some fog effect
in your scene.

82
00:05:41,760 --> 00:05:43,359
To enable that

83
00:05:43,359 --> 00:05:49,200
you need to emit some volume rays
from your light source.

84
00:05:49,200 --> 00:05:52,040
If I get back to this Area Light

85
00:05:52,040 --> 00:05:57,040
and go to the Volume tab
and give it even a small number,

86
00:05:57,040 --> 00:05:58,959
it turns to white,

87
00:05:58,959 --> 00:06:02,559
but here I can get back
to the environment

88
00:06:02,559 --> 00:06:07,519
and now I can give it a color
and a lower value.

89
00:06:07,519 --> 00:06:11,760
Now it'll start to show me the result.

90
00:06:11,760 --> 00:06:14,239
This is the volumetric effect

91
00:06:14,239 --> 00:06:18,880
and I don't wanna use it
for this rendering.

92
00:06:18,880 --> 00:06:21,720
Let me turn off my Area Light here

93
00:06:21,720 --> 00:06:27,559
and use another object
called Redshift Sun & Sky Rig.

94
00:06:27,559 --> 00:06:31,320
We'll create just one Sky
without any light source,

95
00:06:31,320 --> 00:06:38,839
but you can delete that
and create one Sun & Sky Rig.

96
00:06:38,839 --> 00:06:41,559
It gives you light, as well,

97
00:06:41,559 --> 00:06:45,160
and you can simply click
the Redshift Sun

98
00:06:45,160 --> 00:06:49,480
and easily rotate the sun,

99
00:06:49,480 --> 00:06:54,359
change the direction
and change the look and feel.

100
00:06:54,359 --> 00:07:00,000
REDSHIFT
Materials

101
00:07:00,000 --> 00:07:01,720
Here in Redshift

102
00:07:01,720 --> 00:07:05,720
you can go to Materials
and select materials here.

103
00:07:05,720 --> 00:07:09,320
We have different types
of materials in Redshift.

104
00:07:09,320 --> 00:07:13,399
Or you can also go
to your Material Manager

105
00:07:13,399 --> 00:07:18,959
and Create, Redshift and Materials.

106
00:07:18,959 --> 00:07:26,399
If I create one Standard material,
I can easily grab this material

107
00:07:26,399 --> 00:07:31,239
and assign it to my object
in my Viewport.

108
00:07:31,239 --> 00:07:35,000
Or you can just go to the Object Manager

109
00:07:35,000 --> 00:07:39,160
and if I create a new Object,
for example,

110
00:07:39,160 --> 00:07:45,640
in Redshift, Material,
I can assign it to the cone.

111
00:07:45,640 --> 00:07:49,160
And now you can see
I have these materials.

112
00:07:49,160 --> 00:07:51,679
To access all the options
of the material,

113
00:07:51,679 --> 00:07:55,200
you have to double-click
on the Material,

114
00:07:55,200 --> 00:08:06,799
and it opens up one window
called Redshift Shader Graph.

115
00:08:06,799 --> 00:08:12,320
This is where you can access
all the parameters.

116
00:08:12,320 --> 00:08:15,799
You have this material
and you have this output.

117
00:08:15,799 --> 00:08:21,279
This output tells you
where this material has been connected.

118
00:08:21,279 --> 00:08:26,440
If I select this,
I can change the Diffuse

119
00:08:26,440 --> 00:08:29,720
and give it a different color.

120
00:08:29,720 --> 00:08:32,359
Now I can see the result immediately.

121
00:08:32,359 --> 00:08:35,599
Again, don't forget this is
a real-time rendering engine,

122
00:08:35,599 --> 00:08:37,719
which is fantastic.

123
00:08:37,719 --> 00:08:45,080
I can also give some translucency
to my object.

124
00:08:45,080 --> 00:08:49,080
Change the reflection.

125
00:08:49,080 --> 00:08:53,320
The glossiness
or the roughness is different here.

126
00:08:53,320 --> 00:08:58,880
Or you can give it
some Soft Surface Scattering effect.

127
00:08:58,880 --> 00:09:06,559
This effect will be an object like skin
or candle material.

128
00:09:06,559 --> 00:09:12,200
And I can click on the other one
and change that as well.

129
00:09:12,200 --> 00:09:20,599
I can change the Diffuse
to, let's say, a yellowish color.

130
00:09:20,599 --> 00:09:25,559
You can do whatever you want
just playing with the parameters here.

131
00:09:25,559 --> 00:09:30,000
Let's say you want to make
something like glass material.

132
00:09:30,000 --> 00:09:32,880
You can easily change this refraction,

133
00:09:32,880 --> 00:09:38,239
and when you add some weight to it,
it will be like glass material.

134
00:09:38,239 --> 00:09:48,840
You can also give it a color.

135
00:09:48,840 --> 00:09:57,359
Or you can give some tint
and it applies the tint here.

136
00:09:57,359 --> 00:09:59,520
You also have some presets.

137
00:09:59,520 --> 00:10:02,840
If I change it to Glass,
it turns to glass.

138
00:10:02,840 --> 00:10:08,919
It can be Tinted Glass
or Plastic material,

139
00:10:08,919 --> 00:10:14,799
Aluminum or Paper...

140
00:10:14,799 --> 00:10:19,359
or Copper material,
this is one of my favorites.

141
00:10:19,359 --> 00:10:25,679
I zoom in, now you can see
it has a very nice, polished reflection.

142
00:10:25,679 --> 00:10:29,640
That's how you can access
your materials,

143
00:10:29,640 --> 00:10:32,840
but it's not the only types of material
you can assign.

144
00:10:32,840 --> 00:10:39,039
If I go here to Redshift, Material,
you can see I have Car Paint.

145
00:10:39,039 --> 00:10:41,440
Now, if I assign this to the cone,

146
00:10:41,440 --> 00:10:45,679
you can see it's
a double layered material.

147
00:10:45,679 --> 00:10:49,200
And again, if I click on that,

148
00:10:49,200 --> 00:10:55,159
you see some different windows
and parameters here.

149
00:10:55,159 --> 00:11:01,280
I can also create
Incandescent materials.

150
00:11:01,280 --> 00:11:03,440
This can be very helpful

151
00:11:03,440 --> 00:11:08,159
when you are going to apply
some emission.

152
00:11:08,159 --> 00:11:16,679
If I bring in one sphere here,

153
00:11:16,679 --> 00:11:21,200
and assign this Incandescence,

154
00:11:21,200 --> 00:11:24,679
even if I turn off my Area Light here,

155
00:11:24,679 --> 00:11:28,599
I can see...

156
00:11:28,599 --> 00:11:34,840
this result
and I can even add some intensities.

157
00:11:34,840 --> 00:11:39,479
I can add even more.

158
00:11:39,479 --> 00:11:47,000
Let's make sure I have enough GI here.

159
00:11:47,000 --> 00:11:54,679
You can see I have this emission
coming from this sphere.

160
00:11:54,679 --> 00:12:01,679
In Material, you can also give
some Skin material.

161
00:12:01,679 --> 00:12:06,479
This is a ready-to-go material
for a skin type.

162
00:12:06,479 --> 00:12:12,159
I'll turn on my light again,
let me delete this.

163
00:12:12,159 --> 00:12:16,719
This gives me this beautiful result.

164
00:12:16,719 --> 00:12:20,640
We can also add more intensity
to see the result better.

165
00:12:20,640 --> 00:12:25,559
So I'll set this to maybe 15.

166
00:12:25,559 --> 00:12:29,159
So far we have worked
with the real-time rendering,

167
00:12:29,159 --> 00:12:34,520
but what if I want to make
a bucket rendering or finished render.

168
00:12:34,520 --> 00:12:37,039
By pressing this button here...

169
00:12:37,039 --> 00:12:41,599
If I press that,
it starts to render in bucket mode.

170
00:12:41,599 --> 00:12:43,239
I can see some noise here.

171
00:12:43,239 --> 00:12:47,080
To fix that, you can just open up
your render settings here

172
00:12:47,080 --> 00:12:51,200
and in Redshift Basic...
This is very important.

173
00:12:51,200 --> 00:12:54,200
You have Samples Max and Samples Min.

174
00:12:54,200 --> 00:12:58,919
The minimum and maximum
is set to 4 to 16 by default,

175
00:12:58,919 --> 00:13:03,719
but usually if you just set this
to 16 and 64,

176
00:13:03,719 --> 00:13:06,840
it helps a lot to have
a better sampling.

177
00:13:06,840 --> 00:13:13,880
You can also go to the GI,
because GI always creates noise.

178
00:13:13,880 --> 00:13:16,679
Let's open up Brute Force GI.

179
00:13:16,679 --> 00:13:20,440
The number of GI is set to 16,
which is very low.

180
00:13:20,440 --> 00:13:25,200
I can change it to something like 256.

181
00:13:25,200 --> 00:13:30,919
And also the other place
that you have to change that...

182
00:13:30,919 --> 00:13:37,799
All the lights also
have their own samples.

183
00:13:37,799 --> 00:13:39,559
Right now, it's set to 16.

184
00:13:39,559 --> 00:13:45,799
I can change it to 512 for now.

185
00:13:45,799 --> 00:13:52,039
And now, as you see, they start
getting cleaner and cleaner.

186
00:13:52,039 --> 00:13:56,679
You can add more Number here.

187
00:13:56,679 --> 00:14:02,719
You will have a longer render time now.

188
00:14:02,719 --> 00:14:04,840
When you are happy with the result,

189
00:14:04,840 --> 00:14:09,440
you can just stop
this real-time rendering

190
00:14:09,440 --> 00:14:14,599
and then instead of that,
just by pressing this button,

191
00:14:14,599 --> 00:14:22,320
I can turn this to one single image
and then just go to File...

192
00:14:22,320 --> 00:14:24,239
and Save Image as.

193
00:14:24,239 --> 00:14:28,679
You can also send this image
to your RenderView,

194
00:14:28,679 --> 00:14:33,559
or if I just press Shift and R
on my keyboard,

195
00:14:33,559 --> 00:14:37,960
it will send the image
to the RenderView.

196
00:14:37,960 --> 00:14:39,719
You can also press this button

197
00:14:39,719 --> 00:14:44,520
just to send the image
to the Picture Viewer.

198
00:14:44,520 --> 00:14:49,479
In the RenderView again, this button
starts the real-time rendering.

199
00:14:49,479 --> 00:14:52,719
This will create a crop off that render.

200
00:14:52,719 --> 00:14:56,559
If I rotate it,
it just updates that part.

201
00:14:56,559 --> 00:15:00,039
This one will start bucket-rendering,

202
00:15:00,039 --> 00:15:04,880
but just for real-time render,
it's not progressive rendering anymore.

203
00:15:04,880 --> 00:15:08,080
And this will save the render.

204
00:15:08,080 --> 00:15:11,840
If I click on this one,
it can save my render.

205
00:15:11,840 --> 00:15:14,960
And then if I Rotate,

206
00:15:14,960 --> 00:15:19,239
we save again
and I can compare these two together.

207
00:15:19,239 --> 00:15:27,440
It is very nice.
I'll change the material here.

208
00:15:27,440 --> 00:15:30,760
I'll change it to something like Silver.

209
00:15:30,760 --> 00:15:36,840
Now I assign this material.

210
00:15:36,840 --> 00:15:49,679
I can save this and now I can compare
these two together.
