How to Make Realistic Lighting in Roblox Studio — Transcript

Full transcript

1. 0:00My name's Blackeyes, and I believe you
2. 0:01can become a better developer. In this
3. 0:03video, you'll be learning about
4. 0:05realistic lighting. We'll be going over
5. 0:06the different properties and effects
6. 0:08available, so you can turn your
7. 0:09creations from this to this in only a
8. 0:12few minutes.
9. 0:14So, right here I just have the regular
10. 0:16default baseplate. So, what I'm going to
11. 0:18do is [music] open the toolbox and just
12. 0:20look for a free model city that I can
13. 0:22use, because I can't be bothered to
14. 0:24model my own right now.
15. 0:25Let me see what this looks like.
16. 0:29I'd say I can make this work.
17. 0:31I would already say this scene looks
18. 0:33pretty decent as it is, but it can
19. 0:36definitely be elevated. So, I'm just
20. 0:38going to go and delete all of these so I
21. 0:40can start at a blank slate. Now, what I
22. 0:43typically start with is with the sky
23. 0:45texture. So, I go to this plugin called
24. 0:47HDRI Insert, and I just
25. 0:51insert an HDRI. Boom, it already set up
26. 0:54the lighting a little bit, which is
27. 0:56nice. Don't need that old sky anymore.
28. 0:58Now, I want to orientate the sky for the
29. 1:01sun to be like right there. I think
30. 1:03that'd look pretty nice. So, we can do
31. 1:05that by going to the skybox orientation.
32. 1:07Let me just see where the sun [music]
33. 1:08is.
34. 1:10The sun would be right there, so we can
35. 1:12just go into the sky.
36. 1:14Set this to like -45.
37. 1:17I don't know about this one.
38. 1:19How was it before? It was like that
39. 1:20before. [music] That would be pretty
40. 1:22dramatic lighting if I do say so myself.
41. 1:26Honestly, I do like that.
42. 1:28Next, let's add in atmosphere.
43. 1:32Decrease the density by quite a bit.
44. 1:35Say something like that. That's pretty
45. 1:36good. Now, let's tweak these settings.
46. 1:40Now, the ambient affects the shadows and
47. 1:43how dark they will be. And if we want to
48. 1:45add a little color tint, it will show
49. 1:47up. So, we're going to add a little blue
50. 1:50tint to our shadows. Let's increase its
51. 1:52brightness so it can create some better
52. 1:55contrast between that and the shadows.
53. 1:58So, I like turning that up a little bit.
54. 2:00Set to 4.5. Now, I'm going to ignore the
55. 2:03color shift at the bottom. The color
56. 2:05shift top is the parts where the sun
57. 2:07hits. So, I'm going to increase it like
58. 2:09that.
59. 2:10Make it nice and bright, nice and warm.
60. 2:14So, that looks pretty good.
61. 2:15Now, if you go like this, it increases
62. 2:17the shadows and increases the saturation
63. 2:19of where the sun hits. And then,
64. 2:21environmental diffuse. I'm sure there's
65. 2:23something technical that it does, but
66. 2:25that's just what I care about. It's
67. 2:26about how it affects the shadows and
68. 2:28such. I like decreasing it quite a bit.
69. 2:30The sun's too saturated now, so I'm
70. 2:32going to decrease it like that. So,
71. 2:34something like that works. Go back to
72. 2:36the ambient. You can put it like right
73. 2:39there.
74. 2:40Next is the specular, which I tend to
75. 2:44decrease very slightly. Like right
76. 2:47there.
77. 2:48Set the lighting style to realistic and
78. 2:51keep the shadow softness the same.
79. 2:54The outdoor environment, just make it a
80. 2:55little more blue, like that. Next, let's
81. 2:58do
82. 3:00do color correction. Now,
83. 3:03brightness in this one just makes
84. 3:04everything bright instead of just making
85. 3:07the lighter areas brighter. I typically
86. 3:10just leave brightness to how it was, but
87. 3:12that's zero. Now, for contrast, I
88. 3:15typically like making it a little more
89. 3:18punchy by increasing it a little. Make
90. 3:21sure you don't go over the top with it.
91. 3:23Saturation, realistically,
92. 3:26it's a little more desaturated. That
93. 3:28looks better.
94. 3:29But, you know, that's just personal
95. 3:30preference.
96. 3:31Now, for the tint, this makes the tint
97. 3:33of everything.
98. 3:34So, if you do anything here, you want it
99. 3:36to be very subtle. I think I want it to
100. 3:39be just slightly warm.
101. 3:41>> [music]
102. 3:41>> So, I'll bring it up a little bit in the
103. 3:43yellow.
104. 3:44Next,
105. 3:45let's go into the bloom effect. Now,
106. 3:48there's nothing really in the scene that
107. 3:50requires bloom. I'm just going to do a
108. 3:53little trick that I do is turn the
109. 3:54threshold really far down.
110. 3:57Then decrease the size a lot and
111. 4:00decrease the intensity a [music] lot.
112. 4:02So, it just adds a little bit.
113. 4:05A little bit of subtle glowing,
114. 4:07I think it looks pretty good.
115. 4:09Next is the
116. 4:11depth of field effect. Now, the
117. 4:14difference between depth of field and
118. 4:15blur is that blur blurs everything
119. 4:19equally. So, it just makes it look
120. 4:21pretty gross in my opinion. But, the
121. 4:23depth of field only blurs things that
122. 4:26are farther away from the camera. So,
123. 4:28[music] if we just decrease the near
124. 4:30intensity, increase the focus distance,
125. 4:33you can see the things in the background
126. 4:35become more blurry.
127. 4:37You don't want to go over the top with
128. 4:38this effect cuz it can make things look
129. 4:41pretty smudgy and bad.
130. 4:43I'd say that looks good enough.
131. 4:45Now, I would say this looks
132. 4:48pretty good. Pretty good. Pretty good.
133. 4:51And that only took like 10 minutes, so.
134. 4:54I forgot to mention in the recording,
135. 4:55but every environment is different, so
136. 4:57don't copy exactly what I did. Make sure
137. 4:59you tweak the different settings to fit
138. 5:01what you have. Also, the building and
139. 5:03textures can significantly amplify how
140. 5:06your lighting looks. Anyways, make sure
