How to Make Reflections in Roblox Studio — Transcript

Full transcript

1. 0:00Okay, so this is how to make reflections
2. 0:01like this and this in Roblox Studio.
3. 0:03Let's begin. Do you want to learn how to
4. 0:04make these reflections? Well, before we
5. 0:06begin, it's important to know that these
6. 0:08only work on interiors. If you bring
7. 0:10them outside, it will just reflect the
8. 0:11skybox. But inside, they look pretty
9. 0:13cool. But how do we make them? So first,
10. 0:15you want to make a new material variant.
11. 0:17So go up to here, click on the material
12. 0:18manager, and then create material
13. 0:20variant. Add that, find it. Now, all we
14. 0:22need is to change the metalness and the
15. 0:24roughness map. The metalness, you want
16. 0:25to import or use a white image. And for
17. 0:28the roughness, you want to import or use
18. 0:30a black image. And if I just duplicate
19. 0:32this, apply it, you see that it's
20. 0:33reflective. And that's really it. But
21. 0:35there are a lot of cool little things
22. 0:36that you can do to tweak the texture.
23. 0:38Like as you can see all of these here.
24. 0:40Let's first talk about the normal maps.
25. 0:42Now, the normal maps warp how the light
26. 0:44is reflected. So I would only recommend
27. 0:46using these in very specific
28. 0:48circumstances. So you can see it can
29. 0:49create some pretty weird-looking
30. 0:51results. [music] Now, to get normal
31. 0:52maps, all you want is one of these
32. 0:54colors and just plug it into the normal
33. 0:56map. Just copy the decal and paste it in
34. 0:59here. Then you wait for it to load, and
35. 1:00it will create a normal map. Now, all of
36. 1:02these different colors will warp the
37. 1:04reflection differently. Now, to create
38. 1:05these different variants like this, like
39. 1:07a little less sharp, a little more dull,
40. 1:09what you want to do is to darken or
41. 1:10lighten the color of the roughness and
42. 1:12metalness maps. Now, to do that, as you
43. 1:14can see here, the roughness is gray
44. 1:16instead of black, and that creates a
45. 1:18more dulled, a less sharp result. Now,
46. 1:20to make it dull out like this, what you
47. 1:22want to do is decrease the metalness. As
48. 1:24you can see here, this just goes through
49. 1:26the gradient, slightly less reflective
50. 1:28each time. So I would recommend creating
51. 1:30a little color palette like this, and
52. 1:31then just plug in the decal values into
53. 1:33the materials to see how they look. Now,
54. 1:35I will be making some model and linking
55. 1:37it in the description. So if you want to
56. 1:39know how to quickly create these
57. 1:40materials, just open up the model I
58. 1:42linked, go to this folder, select all of
59. 1:44these, copy it, then just paste it into
60. 1:46the material service, then you'll see
61. 1:48all of these pop up. That's how to
62. 1:49quickly do it. Okay, so if you want
63. 1:51reflections that reflect outside, you'll
64. 1:53have to do a couple little tricks.
65. 1:55First, just add in a part, just scale it
66. 1:57like that. Then, make sure this part is
67. 2:00set to a glass material like that. Then,
68. 2:02make sure the transparency is two. Has
69. 2:05to be at least two. [music] You can go
70. 2:06up to 200 or something, but it has to be
71. 2:08at least two. Then, go in and add in a
72. 2:10highlight. Then, set this highlight
73. 2:12transparency to one, the outline
74. 2:14transparency to one, and boom. As you
75. 2:16can see, there's a weird little effect
76. 2:18going on as if it's like magnifying it a
77. 2:20little bit. To increase this effect, you
78. 2:21can go into this part transparency. Just
79. 2:24set this to like 30. You see it becomes
80. 2:25more distorted, more warped, creates a
81. 2:28weird little reflection. But, there are
82. 2:30ways to improve this. So, first we need
83. 2:31to make a custom material. So, you can
84. 2:33just Google in. I'm just going to do an
85. 2:35asphalt texture. Then, just download any
86. 2:37of these. I'll just do this one. Save
87. 2:39it. Then, go into a photo editing
88. 2:41software. I'll be using Photopea. Then,
89. 2:43just open up that texture you
90. 2:45downloaded. Here it is. Now, to create a
91. 2:46puddle-like effect, you want to add in a
92. 2:48little transparent areas. Now, the way I
93. 2:50typically do that is I just duplicate
94. 2:52this, hide that, add in a raster mask.
95. 2:55Then, I select this brush, make sure it
96. 2:57works good, increase the size a little
97. 2:59bit, just create little splotches like
98. 3:01this. Okay, that's good enough for me.
99. 3:02If this was for an actual game,
100. 3:04obviously, you could spend more time.
101. 3:05Then, I just add in a little dodge and
102. 3:08blur to feather out the edges a little
103. 3:10bit better. The more you do this, the
104. 3:11more subtle the puddle will look, the
105. 3:14less drop-off it will have. Then, for
106. 3:15this background one, you want to set it
107. 3:17to like about 30% transparency like
108. 3:19that. Yeah, honestly, set it a little
109. 3:21bit more. Set it to like 40. Okay, then
110. 3:23just download this texture. And another
111. 3:25thing you can do is create a normal map.
112. 3:27So, to do that, go into this website.
113. 3:30I'll link it below in case you want to
114. 3:32use it. So, just load in the image you
115. 3:34created. Then, I like increasing the
116. 3:36bias a little bit. I'd say about 70
117. 3:38works. Just save it. Also, create a
118. 3:40normal map of just a regular texture
119. 3:42without the holes in it. Save that, too.
120. 3:44Okay, once you're back here, add in a
121. 3:46mesh part to workspace. Now, I add in a
122. 3:48mesh part instead of regular part
123. 3:50because I can add in a surface
124. 3:52appearance, which is what I want to use
125. 3:54for this. Go to surface appearance and
126. 3:55on the color map add in that image you
127. 3:58just downloaded and wait for it to load.
128. 4:00Okay, once it loads in like this, you
129. 4:02can increase this part size as much as
130. 4:04you want. Okay, make sure the alpha mode
131. 4:06is set to transparency, let that load.
132. 4:08Now you can also add in your normal map,
133. 4:10so just add in the image, choose the
134. 4:12file, like that. That way it creates
135. 4:14just a little bit more depth. Okay, once
136. 4:15you're done with that, what I typically
137. 4:17do is make this pretty thin. Now we want
138. 4:19to use this reflective material that we
139. 4:20made before. Make sure this is scaled
140. 4:23accordingly. Okay, then also make this
141. 4:25one thin, too. Then what we want to do
142. 4:27is move this one on top of that
143. 4:28transparent material, like that. You can
144. 4:30already see that there are some
145. 4:32reflections going on, but what I
146. 4:34typically do is duplicate this material
147. 4:36and make this surface appearance the
148. 4:38original image without any holes. So
149. 4:40just add in the normal and the original
150. 4:42image, then you'll see the holes go
151. 4:44away. Okay, now with this texture, you
152. 4:46want to drag it underneath the top layer
153. 4:48and the reflective layer, so it's at the
154. 4:50bottom, like that. And there you go,
155. 4:52that's how you make it. Now to change
156. 4:53how it reflects, you can always just
157. 4:55decrease its transparency. There you go.
158. 4:57Player models will reflect in this as
159. 4:59well, so that's another neat bonus.
160. 5:01Also, what you should do with the
161. 5:03reflective part, since it has a
162. 5:04highlight, Roblox Studio only limits 50
163. 5:07highlights, so what you can do is just
164. 5:09disable it there. The effect will still
165. 5:11work, but you can just stack as many of
166. 5:12these as you want now. And that's how
167. 5:14you make it. If you found this video
