How to Import Mesh from Blender to Roblox with Textures — Transcript

Full transcript

1. 0:00In this video, I'll show you how to
2. 0:02bring your models from Blender into
3. 0:03Roblox Studio with textures. In other
4. 0:06words, this tutorial will show you how
5. 0:08to bake materials into images so you can
6. 0:11drop them onto your meshes in Roblox
7. 0:13Studio. I'm using Blender 3.2, but the
8. 0:16steps will be similar in other versions.
9. 0:18This is the model I'll be using. It's
10. 0:20got multiple parts, and we want to bring
11. 0:22them into Roblox Studio separately. So,
12. 0:25I'll show you how to do that. First, we
13. 0:27need to apply any modifiers. If you
14. 0:29haven't used any modifiers, then just
15. 0:31skip ahead. But before we do anything,
16. 0:33I'd suggest you save a copy of the file.
17. 0:43To apply the modifier, just hover your
18. 0:46mouse over it and press Ctrl+ A. We're
19. 0:48doing this so any geometry introduced by
20. 0:51the modifier can be unwrapped.
21. 0:58The next thing you need to do is make
22. 1:00sure every part in your model has unique
23. 1:02materials. In this case, I've used the
24. 1:05same material for both eyes. This would
25. 1:07be fine if each eye were identical, but
26. 1:10the right eye has a slightly different
27. 1:11shape. So, to do that, in the materials
28. 1:14panel, click the duplicate icon. And
29. 1:17this will create a new material with the
30. 1:19exact same nodes.
31. 1:22I don't think there's any other shared
32. 1:23materials, but I'll check just in case.
33. 1:31Now go to the UV editing layout. We're
34. 1:34going to unwrap the model. Select one of
35. 1:36the parts. Make sure you've only
36. 1:38selected a single part, not multiple
37. 1:41parts. Then go into edit mode. You can
38. 1:43also do this by pressing tab on your
39. 1:45keyboard. And then go into face select.
40. 1:48You can do that by pressing three. Then
41. 1:50press A to select every face. Press U to
42. 1:53open the UV menu and select smart UV
43. 1:57project. This is going to automatically
44. 1:59map out all the faces onto a 2D image
45. 2:02for us. Then this menu will open. The
46. 2:05two settings that you might need to play
47. 2:07around with are angle limit and island
48. 2:10margin. Angle limit is the maximum angle
49. 2:13between two faces for those two faces to
50. 2:15be considered part of the same island.
51. 2:18So if you reduce this number, you'll
52. 2:20have more islands and this will reduce
53. 2:22stretching, but each face will have less
54. 2:24pixels. So the resolution will suffer.
55. 2:27Island margin is how much distance is
56. 2:29placed between separate islands.
57. 2:31Increasing this will reduce bleeding
58. 2:33between different islands, but again the
59. 2:36resolution will suffer because each
60. 2:38island has to be scaled down to make
61. 2:40room between them. I'm going to leave
62. 2:41angle limit at 66°. And for island
63. 2:45margin, I'll use a really small value of
64. 2:470.001.
65. 2:49If you go with a smaller resolution for
66. 2:51your textures, you'll need a higher
67. 2:53island margin.
68. 2:56On the left, you can see the unwrapped
69. 2:58mesh. Do this for each part one by one.
70. 3:11And now I've unwrapped all the parts.
71. 3:14Now go into the shading layout.
72. 3:18Here we can see the materials.
73. 3:23Select one of the parts. Then click
74. 3:26inside this area with all the nodes.
75. 3:29Press shift A and search for image
76. 3:31texture.
77. 3:35Then click new to create a new image.
78. 3:37This is where we can decide the
79. 3:39resolution for the texture.
80. 3:43and you should name it something
81. 3:44relevant to keep everything organized.
82. 3:49You want to make sure the image texture
83. 3:50node is selected. On the right, you can
84. 3:53open this menu that shows what node is
85. 3:55selected and it should say image
86. 3:57texture. If you deselect the node by
87. 3:59clicking off, it'll still say image
88. 4:01texture, but you need the node to be
89. 4:03actively selected. So, make sure you
90. 4:05click on the node and then avoid
91. 4:07clicking anywhere else in this window.
92. 4:09And this will just tell Blender which
93. 4:11image you want to bake the materials
94. 4:12onto. This step is really important.
95. 4:15Don't select some other node. Make sure
96. 4:17it's the image texture node that you've
97. 4:19just created.
98. 4:21For the head, I have multiple materials.
99. 4:23We'll want to bake both materials onto a
100. 4:26single image. And I'll show you how to
101. 4:28do that.
102. 4:29First, let's make the image texture node
103. 4:31for one of the materials. For each
104. 4:33separate part, you need to create a new
105. 4:35image. And if you want, you can use
106. 4:38different resolutions for different
107. 4:39parts.
108. 4:41Then let's go into the next material for
109. 4:44the head. Create the image texture node.
110. 4:47This time, click the drop- down menu and
111. 4:49find the image you just created. This is
112. 4:52because we want both materials to be
113. 4:54baked onto a single image. Again, make
114. 4:56sure the image texture node is selected.
115. 4:59And now I'm doing the eyes. Remember
116. 5:01that I created a copy of the eyes
117. 5:03material. If I didn't, then I wouldn't
118. 5:05be able to create an image texture node
119. 5:08for the left and right eyes
120. 5:09individually.
121. 5:24And that's all the image texture nodes
122. 5:26created. Now on the right, click the
123. 5:28camera icon. You'll need to use the
124. 5:30cycles render engine. If we change it to
125. 5:33something else, the baker menu won't be
126. 5:35there anymore.
127. 5:43And in here, you want to set bake type
128. 5:45to the fuse. This bake type will give us
129. 5:47just the color and ignore other
130. 5:49properties.
131. 5:51The direct and indirect options are for
132. 5:54lighting. In this case, I don't want to
133. 5:56bake lighting into the texture. So, I'm
134. 5:59going to uncheck these, leaving just
135. 6:00color.
136. 6:02Before you click bake, make sure you
137. 6:04select every part you're going to bake
138. 6:06the textures for.
139. 6:09Now we can click the bake button.
140. 6:12At the bottom, you can see the progress
141. 6:14for the current texture. This will take
142. 6:16some time, so while you're waiting, make
143. 6:18sure you like and subscribe.
144. 6:22The first texture has finished baking,
145. 6:24which we can see on the left. As more
146. 6:26textures finish baking, you'll see them
147. 6:28pop up there. Now all the textures have
148. 6:30finished baking. Find the textures
149. 6:33you've baked and for each of them you'll
150. 6:35need to save the image. So click the
151. 6:37three bars and under image select save
152. 6:40as. You can also press shift alt s. This
153. 6:43will open the file explorer so you can
154. 6:45choose where to save the image. Before
155. 6:47you save you can change some settings
156. 6:49for the image. I like to set the
157. 6:51compression to zero so saving the image
158. 6:54is a little quicker. Compression won't
159. 6:56affect the image quality for PNG files,
160. 6:59but if you're using something else like
161. 7:00JPEG, then it will have an effect on the
162. 7:03quality. And then let's save. Do this
163. 7:05for the rest of the images you've baked.
164. 7:16And here's all the textures in the file
165. 7:18explorer. All that's left is to export
166. 7:21the meshes. In this case, there's many
167. 7:23parts. It'll take a lot of effort to
168. 7:26export each part one by one. So we can
169. 7:28instead do a batch export. Go to the
170. 7:31scripting layout. In templates under
171. 7:35Python, find batch export.
172. 7:39This is the line that's important. Here
173. 7:42is where we determine the type of file.
174. 7:44Roblox supports FBX, OBJ, or glTF. So we
175. 7:48want to use one of those. For example,
176. 7:51if you want OBJ, you can just swap out
177. 7:53FBX for OBJ. Make sure it's in lower
178. 7:56case.
179. 7:58I'm just going to go with FBX, but it
180. 8:01doesn't really matter what you go with.
181. 8:03Also, make sure all the parts you want
182. 8:05to export are selected. Then, click the
183. 8:08run button.
184. 8:11And here's all the exported parts in the
185. 8:14file explorer.
186. 8:17Now we can open Roblox Studio.
187. 8:21I'm going to create a new place for
188. 8:22this, but you can open any place you
189. 8:24want. First, we need to import the
190. 8:26meshes. Under the home tab, select
191. 8:29import 3D. If you don't have this
192. 8:31button, you can also go to file and
193. 8:33select import 3D. There the file
194. 8:35explorer will open. Just select all the
195. 8:38files you've exported. And in the import
196. 8:40Q window, you can see all the parts
197. 8:42ready to be imported. If we click import
198. 8:45now, the parts won't be in the right
199. 8:47positions. So click on one of the parts
200. 8:49names and in this menu check insert
201. 8:52using scene position. Then click the
202. 8:54three dots and select save as new. Name
203. 8:57this whatever you want. Then click save.
204. 9:00We now have an import preset we can
205. 9:02apply to the rest of the models so they
206. 9:04are in the correct positions. Let's
207. 9:06close this menu. Then right click on the
208. 9:08row with the new preset and select apply
209. 9:11settings to all. Now every part has the
210. 9:13new preset. Let's click import. Once
211. 9:16it's done, we can close this menu.
212. 9:19You'll find all the imported meshes in
213. 9:21the workspace. They'll all be in
214. 9:23separate models.
215. 9:25It's a little big right now, but we can
216. 9:27resize it later. Let's group them all
217. 9:30together by pressing Ctrl G. And I'm
218. 9:32just going to rename it. Then I'll
219. 9:35ungroup the individual models by
220. 9:37pressing CtrlU. Let's resize the model.
221. 9:46Now we need to add the textures. Select
222. 9:48one of the parts. We'll need to put the
223. 9:50texture in this property. We can do this
224. 9:53much easier if we first publish the game
225. 9:55to Roblox. If you've already done that,
226. 9:58you can skip ahead.
227. 10:00Go to file and select publish to Roblox.
228. 10:04Then click create. And you'll have to
229. 10:07wait a bit for the game to publish. Now
230. 10:10select one of the parts again.
231. 10:13And now when we click the property, this
232. 10:16menu pops up. Click add image. Then
233. 10:18choose file and find the image in the
234. 10:20file explorer. Then click create. It'll
235. 10:23take some time for the image to be
236. 10:25uploaded. And now we have the texture on
237. 10:28the mesh. Let's do this for the rest of
238. 10:31the parts.
239. 10:45And now we've brought a model from
240. 10:47Blender into Roblox Studio with
241. 10:50textures. If this video helped you, make
242. 10:52sure you like and subscribe. Thanks for
243. 10:54watching and have a wonderful
