  1. 0:00So, in this video, I'm going to show you
  2. 0:02how to make UGC hair in Blender. We'll
  3. 0:05start by importing the Roblox dummy. So,
  4. 0:07we have some guide for shaping the hair.
  5. 0:10So, let's go to the Roblox Studio. Just
  6. 0:13go into the this upper panel, go to
  7. 0:15avatar, go to rig builder, select R six,
  8. 0:20and select block avatar. Then you will
  9. 0:22see avatar appears in the explorer tab.
  10. 0:25Go into the rig, right click on the rig,
  11. 0:27and save and export. export selection
  12. 0:31and then you will just save it somewhere
  13. 0:32on the desktop and name it I don't know
  14. 0:35dummy. Uh then we can open the blender.
  15. 0:37When you will open the blender you will
  16. 0:39see this scene. So we're going to just
  17. 0:42delete all of it. So press press A and
  18. 0:44delete. Then we want to import the the
  19. 0:47dummy. So let's just go to the file
  20. 0:49import obj and just select the OBJ file
  21. 0:53of a dummy and select and then go to the
  22. 0:56front view. I would just use the
  23. 0:58shortcuts but you can also go here to
  24. 1:00the view. You can just select views from
  25. 1:02here. Then select our character go to go
  26. 1:05to object sect origin and select origin
  27. 1:08to geometry. And then what we want to do
  28. 1:12is basically just just snap selection to
  29. 1:15the cursor. So it's so our dummy is in
  30. 1:18in the center. I will just be make a
  31. 1:20collection and name it dummy. We're
  32. 1:23going to move this model to the dummy
  33. 1:26collection. So we can everything is more
  34. 1:29is uh much more organized. So I can just
  35. 1:32I press shift A go to mesh and select
  36. 1:35circle under this panel. Select vertices
  37. 1:38and type three. Press enter. And you
  38. 1:40will see if you go to the top view we
  39. 1:43have this triangle. I will go to edit
  40. 1:46mode. Select this vert G and Y. And I
  41. 1:50will just
  42. 1:52slightly move a bit down. So it's so our
  43. 1:56hair strand will be a little bit
  44. 1:58thinner. So with that I can go here and
  45. 2:01name it hair shape.
  46. 2:06Hair shape go under object select
  47. 2:09convert and convert it to curve. We can
  48. 2:12hide this one. So now we will make air.
  49. 2:16You will press shift A. Go to curve
  50. 2:19under the and select pet. I will rotate
  51. 2:21this pad 90° by typing R and 90. Now you
  52. 2:27select the path, go to curve properties
  53. 2:31under the GI geometry
  54. 2:34under the object and select air shape.
  55. 2:36You will see that our shape is rotated
  56. 2:39to the wrong way. So go to edit mode,
  57. 2:42press A to select all, press CtrlT, 90.
  58. 2:46We will right click on it and shade it
  59. 2:48flat. And you can see this will be our
  60. 2:51hair. I will basically tell you the main
  61. 2:53controls. You can select whatever vert
  62. 2:56you want in edit mode and press G. And
  63. 2:59you can see you will you can move it.
  64. 3:01You can move this one, this one, this
  65. 3:03one, what whatever vert you want. And we
  66. 3:06will also use CtrlT to rotate the verts
  67. 3:11to basically tilt the verts. And we will
  68. 3:14use alt s alt s to basically shrink the
  69. 3:19hair. So with that we will make a hair.
  70. 3:21I will select this vert. Press alt s and
  71. 3:24zero. shrink it to the zero. And we will
  72. 3:27select this one. This vert. And we will
  73. 3:30do the same. And I can see this too
  74. 3:32thick. I will select all. And just
  75. 3:35shrink it a little bit. And this will be
  76. 3:38our hair. So now we'll start with
  77. 3:40modeling the hair.
  78. 3:42uh we will start modeling from the back
  79. 3:44of the hat and work way to the front.
  80. 3:46And after the main shape of the hair is
  81. 3:48done, we're going to add some details.
  82. 3:51So what we want to do is unhide the
  83. 3:54dummy and basically as you can see our
  84. 3:57hair is too long and it's rotated the
  85. 4:01wrong way. So I will select this one,
  86. 4:03shrink it a little bit, move move it up
  87. 4:07and with in edit mode I will basically
  88. 4:11Ctrl T 90
  89. 4:16once more and you can see it's basically
  90. 4:19here in the back of the head. I will
  91. 4:21just use G
  92. 4:26to
  93. 4:28basically make a shape that I want.
  94. 4:36I think it's a little bit too thick.
  95. 4:40We I will add thickness with alt s on
  96. 4:42the vert and basically just shrink it a
  97. 4:44little bit. I will also add thickness
  98. 4:48here
  99. 4:49[Music]
  100. 4:53and see it's a bit a bit too thick.
  101. 5:00[Music]
  102. 5:07Now I will duplicate this hair by shift
  103. 5:11D and I will go to the edit mode and
  104. 5:14just I will just move it a little bit.
  105. 5:17So this will be our second hair. It's a
  106. 5:20little bit too thick.
  107. 5:23[Music]
  108. 5:28As you can see from the top it's a
  109. 5:30little bit too further from the this
  110. 5:32main shape from this hair strand. So I
  111. 5:36will go to side view, select these ones
  112. 5:40and just put it a little bit
  113. 5:45a little bit further.
  114. 5:58I want to mirror this hair to the other
  115. 6:01side. We will do this like that. So
  116. 6:03press A. Go to empty, select plane axis.
  117. 6:08We can hide the empty. Select this pair.
  118. 6:12Go to modifiers. Add modifier and select
  119. 6:15mirror modifier. And under the mirror
  120. 6:18object, select select the empty. And you
  121. 6:20can see we added the left side. And
  122. 6:23basically when we are going to control
  123. 6:25this part, the other half will behave
  124. 6:27like that too. So I'm just basically
  125. 6:29here aligning these edges. So basically
  126. 6:34when we're going to merge all of these
  127. 6:36it will be a much it will be much
  128. 6:38easier. So the back is I think it's
  129. 6:41okay. Now we're going to add a pet
  130. 6:45because I will do the different
  131. 6:48uh the different hair.
  132. 6:54[Music]
  133. 7:00Go to curve properties under object
  134. 7:04select hair shape shade it flat and we
  135. 7:07can see it's rotated to the wrong side.
  136. 7:09Uh we will go to edit mode press a ctrl
  137. 7:14t and press 90. We need to rotate it in
  138. 7:19our way. Press a alt s and shrink it a
  139. 7:22little bit. This for this hair, this
  140. 7:25curve will be shrink to the zero. But
  141. 7:28this one will be open like that but a
  142. 7:32little bit
  143. 7:34less
  144. 7:37cuz we want to make like this one. Let's
  145. 7:41see.
  146. 7:43Go like that.
  147. 7:50[Music]
  148. 8:01We will do the same as we did before
  149. 8:03with the mirror modifier. So just select
  150. 8:06this one. Go to modifiers and select
  151. 8:09mirror modifier. Press mirror object and
  152. 8:12select empty. And you will see there is
  153. 8:15another one. We'll select clipping.
  154. 8:32[Music]
  155. 8:45[Music]
  156. 8:55[Music]
  157. 8:57Heat. Hey, Heat.
  158. 9:00[Music]
  159. 9:06[Music]
  160. 9:18So if we if we have holes like that,
  161. 9:20don't worry because we will we will
  162. 9:23merge them together anyway. So it
  163. 9:25doesn't matter.
  164. 9:27[Music]
  165. 9:30But we can always check how is how does
  166. 9:32it look when the dummy is selected. So
  167. 9:35we will add one more hair here and then
  168. 9:38we will add uh basically the front part
  169. 9:41of the hair and then bangs. I will
  170. 9:44duplicate this one. So by selecting this
  171. 9:47and shift D I will move it just a little
  172. 9:50bit further.
  173. 9:52I will shrink it a little bit. Select
  174. 9:55this birds and tilt it a little bit.
  175. 10:00So it's open.
  176. 10:02[Music]
  177. 10:14[Music]
  178. 10:25[Music]
  179. 10:37So with that set, we're going to add
  180. 10:39pet.
  181. 10:41Rotate it 90°. Select. I would just
  182. 10:45shrink it a little bit. Go to front view
  183. 10:49and try to align
  184. 10:52that flow of this hair.
  185. 11:00So, let's just go to curve properties,
  186. 11:03go to geometry and under bevel, select
  187. 11:06object shape. Um, we need to shade it
  188. 11:10flat and rotate it. Just go select A
  189. 11:13with alt S. Shrink it a little bit.
  190. 11:18And I want this vert to scale to zero.
  191. 11:33[Music]
  192. 11:44[Music]
  193. 11:56[Music]
  194. 11:57So now I will start the banks. I will
  195. 12:00make error as we did before.
  196. 12:08For the banks, I will only shrink the
  197. 12:11bottom vert.
  198. 12:13And I will shrink it a little bit and
  199. 12:16make it.
  200. 12:19I will bring it to the front.
  201. 12:29We must align the edges.
  202. 12:39Something like that. And we will mirror
  203. 12:42this part. And now we will start with
  204. 12:44the inner part.
  205. 12:50[Music]
  206. 12:58[Music]
  207. 13:07[Music]
  208. 13:16With that we can and use proportional
  209. 13:19editing too to make it more like flowy
  210. 13:21more realistic. So for that we're going
  211. 13:24to this upper panel. Select this one and
  212. 13:27basically I will just smooth. I will
  213. 13:29just use this smooth one and select on
  214. 13:32it only. You can see I can grab it and
  215. 13:34with mouse wheel up and down I can
  216. 13:37control the influence of it.
  217. 13:40[Music]
  218. 13:53[Music]
  219. 13:55Move this part a little bit in. This one
  220. 13:57a little bit out. Make that O shape.
  221. 14:08[Music]
  222. 14:16You can make it easier and just just
  223. 14:19select this part and press shift D to
  224. 14:21duplicate it. And I can just move it out
  225. 14:24of the way. And we have another one
  226. 14:26without repeating the creating path and
  227. 14:29all of that. So, it's much much faster
  228. 14:31and much easier.
  229. 14:38[Music]
  230. 14:49[Music]
  231. 15:23[Music]
  232. 15:34[Music]
  233. 15:37So, we've just ended with the base. So,
  234. 15:40I'm going to start with some with adding
  235. 15:42some details. So after that we'll start
  236. 15:44with margin.
  237. 15:46[Music]
  238. 15:57[Music]
  239. 16:08[Music]
  240. 16:19[Music]
  241. 16:58[Music]
  242. 17:11[Music]
  243. 17:21[Music]
  244. 17:28So now we need to basically select the
  245. 17:31hair and lower resolution of the hair.
  246. 17:34So for that we're going to go curve
  247. 17:37properties and we will just in this tab
  248. 17:41where there is 12 we're going to type
  249. 17:42six and we will repeat this step with
  250. 17:46all the hairs.
  251. 17:48[Music]
  252. 18:06[Music]
  253. 18:08After we finish with lowering
  254. 18:09resolution, we can start merging the
  255. 18:12hairs. And for that, we need to we need
  256. 18:14to basically turn off the mirror
  257. 18:16modifier for all of the hairs.
  258. 18:20I I will only disable this one first and
  259. 18:22I will do the others later. I will hide
  260. 18:25the details and I will start with this
  261. 18:27one. Basically we what we want to do is
  262. 18:30just to align we need to align the edges
  263. 18:33more because they are not aligned good.
  264. 18:35I think that's good. So now we want to
  265. 18:38go to we want to select this hair go to
  266. 18:41object and select convert and converted
  267. 18:44to mesh. And we want to do this same
  268. 18:46with this hair. Now when both of these
  269. 18:49hairs are converted to mesh we want to
  270. 18:51select both of them press right click
  271. 18:54and join. Now we can go to edit mode and
  272. 18:56basically we go a clue press M and merge
  273. 18:59it at center. So we can repeat that with
  274. 19:02all of the hair.
  275. 19:06By merging all of these uh verts we will
  276. 19:09make that hair has a lot less tries and
  277. 19:13there won't be any holes in the mesh. So
  278. 19:15it will be perfect for Roblox Studio. If
  279. 19:18we have vert like that can just press
  280. 19:20CtrlR we can basically add an edge loop
  281. 19:24can just select both of these verts and
  282. 19:26merge it at center. We can do the same
  283. 19:29here and we successfully merge this
  284. 19:32hair. We want to repeat this process
  285. 19:34with all of the hair.
  286. 19:36[Music]
  287. 19:48[Music]
  288. 19:59[Music]
  289. 20:10[Music]
  290. 20:22[Music]
  291. 20:27After we merge all of this part, we can
  292. 20:29go to mirror modifier and apply it. We
  293. 20:33can basically we can also select this
  294. 20:37clipping and go to edit mode and slide
  295. 20:40all of these birds to the center.
  296. 20:46So the mesh is even cleaner. And
  297. 20:48basically this part is done. We can hide
  298. 20:52this part and this one. Now we have this
  299. 20:55part to merge. It's the same process as
  300. 20:57before. We need to hide the mirror
  301. 21:00modifier. Select this object and convert
  302. 21:03it to mesh. We do the same with this
  303. 21:06part.
  304. 21:10And so we can see I can only work on one
  305. 21:13half and the other half is doing the
  306. 21:15same. So it's much faster. For now,
  307. 21:18we're going to leave this part and we're
  308. 21:20just going to focus on this one. So for
  309. 21:22that one, we need to merge all of this
  310. 21:26part so there won't be any holes on it.
  311. 21:34[Music]
  312. 21:45[Music]
  313. 21:48Uh go to object convert it to mesh. And
  314. 21:52now I will join these parts. Right click
  315. 21:55and select join. And I can merge this by
  316. 21:59pressing M and select at the center
  317. 22:06[Music]
  318. 22:11with this vert with this edges which
  319. 22:15basically don't have any connecting any
  320. 22:17verts that I can connect. I will I can
  321. 22:20just dissolve this edge. So basically go
  322. 22:22to edge selection, hold alt, press on
  323. 22:25the edge and click ctrl and x and you
  324. 22:28can see the edge is dissolved and repeat
  325. 22:30this with all of these edges here.
  326. 22:34[Music]
  327. 22:35That's it. Now I can apply mirror
  328. 22:37modifier.
  329. 22:39Now I can focus on this part this and
  330. 22:41this. Go to object convert it to mesh
  331. 22:45and now press. We can also use the
  332. 22:48shortcut Ctrl J to join them. And now I
  333. 22:51can merge them.
  334. 23:04[Music]
  335. 23:15[Music]
  336. 23:38Same with this one. If we want to
  337. 23:40disable the mirror modifier to just
  338. 23:42focus on one part and then after we
  339. 23:44merge it, we can uh mirror it then. So
  340. 23:48it's much easier. So I would just adjust
  341. 23:51a little a little better this edges so I
  342. 23:53can it will be a lot more easier for
  343. 23:56merging. I will select this and this. I
  344. 23:59will go under object and under convert I
  345. 24:02will convert it to mesh. And I will also
  346. 24:05press Ctrl J to join them. Go to uplute
  347. 24:10and to edit mode and I will just start
  348. 24:12merging this at center by clicking M and
  349. 24:16at center. This one is a little bit
  350. 24:18trickier.
  351. 24:23I think this will this will be okay. And
  352. 24:26now we can apply mirror modifier. If we
  353. 24:29want to publish this hair on the Roblox
  354. 24:31marketplace and make some money and make
  355. 24:34some Robuxes, we need to lower our
  356. 24:37triangle count. So, it must be under
  357. 24:394,000 tries. I can show you how you can
  358. 24:42see this how much you have. So,
  359. 24:44basically, you will go up here in
  360. 24:46overlays and you will select statistic.
  361. 24:49And now you can see in the left corner
  362. 24:52we have 4,56
  363. 24:54tries. So, this is too much. We need to
  364. 24:57go, we need to lower it under the 4,000
  365. 25:00tries. So, I will show you how to do
  366. 25:02that. First of all, we will select this
  367. 25:04big part and we will go to edit mode and
  368. 25:07to edge selection. We can select it
  369. 25:09here. And as you can see, there is a lot
  370. 25:12of this edge loops. So, we can dissolve.
  371. 25:15The better edges to dissolve are the
  372. 25:18ones that are on the flat surface like
  373. 25:20like that. So, by clicking alt and
  374. 25:22selecting them, you're selecting the
  375. 25:24whole edge. Then you're going to press
  376. 25:26Ctrl and X and you will see the edges
  377. 25:29deleted. I will I will delete this edge.
  378. 25:31I will delete this edge. We also don't
  379. 25:34need this one and this one. This and
  380. 25:36this. We can go into the side view. We
  381. 25:39don't need this one.
  382. 25:44So as you can see in this in this part
  383. 25:46there is too many loops. We can dissolve
  384. 25:50many of those. So I can do this and this
  385. 25:53and this. I will do this with with other
  386. 25:56art.
  387. 26:01[Music]
  388. 26:13[Music]
  389. 26:35[Music]
  390. 26:48After we reach triangle count under four
  391. 26:514,000 tries, we can start merging all
  392. 26:55the part that we didn't convert it to
  393. 26:57mesh and basically join the whole mesh
  394. 27:01together.
  395. 27:09[Music]
  396. 27:12Um, now I can apply apply this uh mirror
  397. 27:15modifier so I can so I can basically
  398. 27:19merge the verts on the back of this hair
  399. 27:21strand. So,
  400. 27:24and apply it. Now I can convert this and
  401. 27:27convert this to mesh. Select this part
  402. 27:29and this part. Right mouse click and
  403. 27:31join. Now I can start merging the back.
  404. 27:45I will add edge loop here. So I can
  405. 27:47connect these birds and this one. Now I
  406. 27:50have repeat with this one.
  407. 27:57This part is not connected to this one.
  408. 27:59So I need to join them together. Just go
  409. 28:01to mirror modifier and apply it. Select
  410. 28:05this part and this part and right click
  411. 28:07and join. Then we can start merging.
  412. 28:09[Music]
  413. 28:17[Music]
  414. 28:24I can also apply this
  415. 28:28[Music]
  416. 28:40[Music]
  417. 28:48And basically that's it. Now I can press
  418. 28:50Ctrl A and right click and join. And we
  419. 28:53have and with that we put all parts into
  420. 28:56one mesh. So it's united into one mesh.
  421. 28:58And as you can see, it's a little bit
  422. 29:01not smoothed out. It's a little bit
  423. 29:02flat. We want to smooth this hair up. So
  424. 29:06just right click on it and shape auto
  425. 29:08smooth. And as you can see, it's much
  426. 29:10more more smooth.
  427. 29:13So now after we finished the hair, we
  428. 29:16want to check a few things. So the first
  429. 29:18thing is to make sure that that the
  430. 29:21normals are pointed the right way. So we
  431. 29:24want to make we want to check that. So
  432. 29:27we do that by going here to view port
  433. 29:29overlays and just select the face
  434. 29:31orientation. As we can see the blue part
  435. 29:34is okay. That means that normals are
  436. 29:36pointed the right way. But the red means
  437. 29:38that they're not. So basically we need
  438. 29:40to flip them. We can do that by
  439. 29:43selecting the object going to edit mode
  440. 29:46press A and then just press shift and N.
  441. 29:48And we can see it flips. But this part
  442. 29:50is missing. So we need to hover over
  443. 29:53this part and press L and then shift and
  444. 29:56N. And here we want to recalculate
  445. 29:58normals and just check inside. And here
  446. 30:01we go. This is how we check the face
  447. 30:03orientation. And now you can basically
  448. 30:05turn off this this feature. So after we
  449. 30:08flipped our normals, we want to add some
  450. 30:11textures. We do that by going to this
  451. 30:14material preview. Just click on this
  452. 30:16icon. As you can see, we don't have any
  453. 30:19textures. So we will apply that. What
  454. 30:20you want to do is go here and just
  455. 30:25slide a new window. In this step, we
  456. 30:27will open shader editor. We you will go
  457. 30:29into this icon and just you will select
  458. 30:32shader editor and this window will pop
  459. 30:35out. You will press on this principlef
  460. 30:38and press ctrlt. Now in this image
  461. 30:41texture you will open your hair texture.
  462. 30:44I will choose one of my own.
  463. 30:47Let's say this one. But as you can see,
  464. 30:50our texture is not correct. It's flip on
  465. 30:53the right. So, we want to fix that. So,
  466. 30:56go to UV editor and under this icon,
  467. 31:00select our texture. Go to this tab,
  468. 31:02select our mesh, go to edit mode, select
  469. 31:06all, and just press R and rotate it like
  470. 31:1090°. As you can see, our UV texture is
  471. 31:14fixed.
