Creating 3D Character with AI in 1 Min vs 1 H vs 10 H — Transcript

Full transcript

1. 0:00In this video I
2. 0:01gonna challenge myself to
3. 0:02create a character with
4. 0:04AI in limited time.
5. 0:06We gonna start with
6. 0:071 minute, then 1
7. 0:08hour, and then 10 hours.
8. 0:10Well, actually 10 hours
9. 0:12was too much and
10. 0:136 hours was enough
11. 0:14to get it perfect.
12. 0:15Anyway guys, you always
13. 0:16ask me like if
14. 0:18we can create character
15. 0:19faster or someone actually
16. 0:21ask how we can
17. 0:21create it better.
18. 0:22So it's a perfect
19. 0:23opportunity to introduce a
20. 0:24few approaches and see
21. 0:26what quality we can
22. 0:27actually reach.
23. 0:27Let's start with 1 minute.
24. 0:29Well, 1 minute is
25. 0:31not enough to even
26. 0:32generate a 3D model.
27. 0:34But let's say we
28. 0:35can generate 3D model
29. 0:37within a minute.
30. 0:38It will take around
31. 0:382 -3 minutes.
32. 0:40I gonna use Tripo
33. 0:41and the recent P2
34. 0:43which is like the
35. 0:44best low poly possible.
36. 0:45It also generating quads etc.
37. 0:48So we gonna generate
38. 0:48character there.
39. 0:49Here we can see
40. 0:50the mesh.
41. 0:50I mean like if
42. 0:51I see this mesh
43. 0:52like year ago I
44. 0:53would say like this
45. 0:54is like most perfect
46. 0:55mesh etc.
47. 0:56But what we gonna
48. 0:57do later will be
49. 0:58even better.
50. 0:59And the second step
51. 1:00will be to actually
52. 1:01texture it.
53. 1:02When you do it
54. 1:03with P2 it requires
55. 1:042 step.
56. 1:06Okay, after approximately 3
57. 1:08minutes here is our result.
58. 1:10Well, it is indeed
59. 1:11a 3D model but
60. 1:12we can definitely spot
61. 1:13some blurry spots like
62. 1:15eyes etc.
63. 1:16I mean there's quite
64. 1:17a lot of things
65. 1:17that we definitely want
66. 1:18to improve.
67. 1:19And since we Do
68. 1:20not have any time
69. 1:21to do the rigging
70. 1:22like if we bring
71. 1:22it to Unreal Engine
72. 1:23it will be like this.
73. 1:26Alright, let's take things serious.
74. 1:28One hour.
75. 1:29And to increase the
76. 1:30quality in one hour
77. 1:31generation most important thing
78. 1:33where I gonna invest
79. 1:34my time is to
80. 1:35generate my model in parts.
81. 1:37I mean we gonna
82. 1:38use the same Tripo
83. 1:40P2 with the smart
84. 1:41mesh but I gonna
85. 1:42approach it part by
86. 1:43part and set different
87. 1:45settings for the mesh.
88. 1:46The good thing about
89. 1:47P2 is that it
90. 1:48generates meshes very fast
91. 1:50and you can iterate
92. 1:52like usually takes like
93. 1:541 -2 max retries
94. 1:56with the different polycount
95. 1:58settings to get the
96. 1:59right polycount, right stance,
97. 2:02you know like right
98. 2:03wireframe etc.
99. 2:04I mean it's insanely
100. 2:05good model.
101. 2:06Here by the way
102. 2:07you can see what
103. 2:08parts are extracted.
104. 2:09Again, usually I go
105. 2:10like this.
106. 2:11Like there is the
107. 2:12body, there is head
108. 2:13and again like all
109. 2:15the separately of course
110. 2:16like weapons and stuff
111. 2:18also separate.
112. 2:19I mean it just
113. 2:20works better that way.
114. 2:21I mean you don't
115. 2:22need to go like
116. 2:22crazy splitting every single detail.
117. 2:25I would say like
118. 2:26think about like some
119. 2:27detail that fit like
120. 2:28within 500 to 1000
121. 2:30polygons, right?
122. 2:30Here you can see
123. 2:31all parts on the
124. 2:32screen which I decided
125. 2:33to go with.
126. 2:34And again in terms
127. 2:35of wireframe most of
128. 2:36the cases again I
129. 2:38was extremely happy from
130. 2:39first trial.
131. 2:40I mean with this
132. 2:41approach it is crazy
133. 2:42how good.
134. 2:43This wireframe look like.
135. 2:44I mean of course
136. 2:45it can break and
137. 2:46there are some edge cases.
138. 2:47I would say like
139. 2:48with some realistic garment etc.
140. 2:51It might not work
141. 2:52that well.
142. 2:53I did a video
143. 2:54about it but overall
144. 2:55for characters specifically especially
145. 2:57styled characters.
146. 2:58Such as mine it
147. 2:59works extremely good.
148. 3:00You see what you see.
149. 3:02I remember someone was
150. 3:03asking in the comments
151. 3:04if I.
152. 3:05Don't do realistic characters
153. 3:07intentionally but I mean
154. 3:08I actually like styled
155. 3:09character more and I
156. 3:11think they are more creative.
157. 3:12But don't worry I
158. 3:13already working on the
159. 3:14video showing you how
160. 3:15to do realistic characters
161. 3:17and in my opinion
162. 3:18that's actually easier.
163. 3:19To generate.
164. 3:20All parts I actually
165. 3:21spent more than 30 minutes.
166. 3:23So now I don't
167. 3:24have much time left
168. 3:25and I need to
169. 3:26assemble them in.
170. 3:27Blender quickly and get
171. 3:29some time to rig
172. 3:30it and put to
173. 3:30Unreal Engine so it
174. 3:31finally actually moves.
175. 3:32And the good news
176. 3:33here that.
177. 3:34I will be able
178. 3:35to do that really quick.
179. 3:36So process here quite simple.
180. 3:37Cut some duplicating parts
181. 3:39and assemble things.
182. 3:41Carefully together.
183. 3:42With Blender sculpting modes
184. 3:44or Blender proportional editing
185. 3:46that is like super
186. 3:47super easy.
187. 3:48Again like you just.
188. 3:49Need like few brushes.
189. 3:50Anyway 20 minutes later
190. 3:51I have my character
191. 3:53assembled and now it's
192. 3:55time to rig it.
193. 3:56And.
194. 3:56There's two ways that
195. 3:57we can do that.
196. 3:57Like you can drop
197. 3:58all together without weapons
198. 4:00of course and just
199. 4:02rig it all together.
200. 4:03Or you can separate
201. 4:04the parts that will
202. 4:06be static anyway.
203. 4:07Like accessories again they
204. 4:09are not bending right
205. 4:10so they are signed
206. 4:11100 % to some
207. 4:12one bone.
208. 4:13So I gotta do
209. 4:14quickly the aqua rig
210. 4:15like because I don't
211. 4:16have a lot of
212. 4:17time and quickly for
213. 4:18some rigid objects like
214. 4:20the waist accessories I'm
215. 4:21gonna need to set
216. 4:23100 % weights to
217. 4:24some specific bones.
218. 4:25That's pretty much it
219. 4:26I don't have time
220. 4:27to anything else.
221. 4:28Quickly bringing my character
222. 4:30to Unreal Engine and
223. 4:31I have to quickly
224. 4:33set some materials and
225. 4:35target the animation to
226. 4:36the controller.
227. 4:37So it was a
228. 4:38little bit more than
229. 4:39an hour like hope
230. 4:40you forgive me like
231. 4:41for this extra three minutes.
232. 4:43And here we go
233. 4:44my character is in
234. 4:45Unreal Engine and so
235. 4:46we can actually walk
236. 4:48around and it actually
237. 4:49looks not bad right.
238. 4:50But what do we
239. 4:51see here we of
240. 4:52course see the lack
241. 4:53of any physics.
242. 4:54We do have tail
243. 4:55we do have some
244. 4:56stuff around like I
245. 4:58mean that is absolutely
246. 4:59rigid and definitely we
247. 5:01can set materials better right.
248. 5:03Okay so moving to
249. 5:04the 10 hours.
250. 5:05So what's gonna be
251. 5:06different now?
252. 5:06Well actually for generation
253. 5:08we're gonna use exactly
254. 5:09the same approach.
255. 5:10I still gonna go
256. 5:12with PPP2 maybe just
257. 5:13spend a little bit
258. 5:14more time generating parts
259. 5:15because I learned what
260. 5:17parts are missing like
261. 5:18while assembling it last time.
262. 5:19So I'm gonna generate
263. 5:21few more parts.
264. 5:22There was some back.
265. 5:23accessories.
266. 5:23I also gonna give
267. 5:25few retries to some
268. 5:26of the objects I
269. 5:27was not really happy
270. 5:28and I was forced
271. 5:29to move fast last
272. 5:30And if.
273. 5:31You're a professional 3d
274. 5:32artist you might ask
275. 5:33me but why if
276. 5:34I have 10 hours
277. 5:35I don't choose to
278. 5:36go with high poly
279. 5:37to low poly.
280. 5:38Well that's a good
281. 5:39question that is actually
282. 5:41possible if you will
283. 5:42have quite a lot
284. 5:43of detailed measures and
285. 5:44you want to bake normal.
286. 5:45Maps You can generate
287. 5:47something high poly then
288. 5:48retrypology etc.
289. 5:49But at this very
290. 5:50moment I recording this
291. 5:52video PPP2.
292. 5:53Produces much better low
293. 5:55poly especially with quads
294. 5:57than any retrypology.
295. 5:59Well for retrypology we.
296. 6:00Have options such as
297. 6:01Tripo retrypology and also
298. 6:03Hunyuan retrypology.
299. 6:04And I must say
300. 6:05quality of mesh that
301. 6:05Tripo p2 provides is so.
302. 6:07Much better that I
303. 6:08just prefer to move
304. 6:09along with this low
305. 6:11poly models and add
306. 6:12details on texture and
307. 6:13I gonna show you
308. 6:14how to do.
309. 6:15That And also I
310. 6:16say sometimes skipping retrypology
311. 6:18baking all that stuff.
312. 6:20Not completely there will
313. 6:21be few things to.
314. 6:22Do but still.
315. 6:23And by the way
316. 6:24guys if you want
317. 6:24to try Tripo itself
318. 6:25you can try it
319. 6:26for free and by
320. 6:27my link in the
321. 6:28description you gonna get.
322. 6:29500 credits if you
323. 6:31are a new user.
324. 6:31Now I gonna bring
325. 6:33all these parts again
326. 6:34to Blender and start assembling.
327. 6:36Actually it will.
328. 6:37Be pretty much the
329. 6:38same base so behind
330. 6:39the scene I.
331. 6:40Actually can reuse what
332. 6:41I already did in
333. 6:42one hour but I
334. 6:43gonna just pay more
335. 6:44attention to how accurate
336. 6:46details are.
337. 6:47And as I mentioned
338. 6:48it still can produce
339. 6:50some artifacts there might
340. 6:51be some issues with
341. 6:53the mesh etc.
342. 6:53So I gonna take
343. 6:55my time to address
344. 6:56all of them.
345. 6:57There are not a
346. 6:58lot but again there
347. 6:59can be some stuff
348. 7:01that you just want
349. 7:02like to smooth or
350. 7:03fix or maybe update
351. 7:05the wireframe.
352. 7:06You'll see all the
353. 7:07timelines that I did.
354. 7:08Altogether assembling, fixing some
355. 7:11geometry somewhere it was
356. 7:13a bit spent I
357. 7:14had to straighten that
358. 7:15or some small that.
359. 7:17Altogether it took like
360. 7:19around 40 minutes.
361. 7:21And yeah I also
362. 7:22had to fix some
363. 7:23holes, cap some polygons
364. 7:25or optimize mesh a
365. 7:26little bit.
366. 7:26For example I added
367. 7:27an accessory a scarf
368. 7:28and I want it
369. 7:29to be a single
370. 7:30plane because I want
371. 7:31to add the cloth
372. 7:32physics later.
373. 7:33Like when it's double
374. 7:35sided like it's not
375. 7:36that convenient so I
376. 7:37gonna just cut it.
377. 7:38Okay now it looks
378. 7:39much better and it
379. 7:41will be easier for
380. 7:42me to add physics.
381. 7:43When I finalized my
382. 7:44mesh it's about time
383. 7:45to do the unwrapping.
384. 7:47And it's never been
385. 7:48easier to do the
386. 7:49unwrapping for AI generated
387. 7:51mesh as when you
388. 7:52work with cheapo P2.
389. 7:53Because guys this mesh
390. 7:54is logical and you
391. 7:56can go and compare
392. 7:56it yourself.
393. 7:57Like it's so much
394. 7:58easier like first of
395. 7:59all logical means that
396. 8:00you can easily manipulate.
397. 8:02With some separated parts
398. 8:04within the object.
399. 8:05Second it's so much
400. 8:06easier to work with
401. 8:08seams and set the.
402. 8:09Seams for UV purpose.
403. 8:11To completely unwrap my
404. 8:12character it took me
405. 8:13only 30 minutes which
406. 8:15I think is crazy.
407. 8:16And.
408. 8:16Why do you need
409. 8:17that right UV?
410. 8:18Well good UV give
411. 8:19you some benefits.
412. 8:20Like you can do
413. 8:21nice baking, pack texture
414. 8:22nicer in lower.
415. 8:24Resolution It is way
416. 8:25more editable.
417. 8:26It has less artifacts.
418. 8:27When you have like
419. 8:29thousands of islands it's
420. 8:30very difficult to.
421. 8:31Avoid small artifacts.
422. 8:32And I want to
423. 8:33get best quality so
424. 8:34we need to care
425. 8:35about optimization.
426. 8:36And later I also
427. 8:37gonna add materials.
428. 8:38So all these things matters.
429. 8:40So after doing UV
430. 8:41unwrap I re -baked
431. 8:42the color in one
432. 8:44bigger texture space and started.
433. 8:46To address some texture issues.
434. 8:48Like I mean there
435. 8:48are plenty of ways
436. 8:49how you can do that.
437. 8:50You can try to
438. 8:51do that in Blender
439. 8:52like with the.
440. 8:53Clone brush just addressing
441. 8:55some issues like again
442. 8:56like depending like how
443. 8:58lazy you are.
444. 8:59Or you can take
445. 9:00it to.
446. 9:00Modi for example.
447. 9:01It's one of my
448. 9:02favorite tools where you
449. 9:03can actually generate texture
450. 9:05from image reference and
451. 9:06apply, fix some holes.
452. 9:08Etc But most of
453. 9:09that approaches only really
454. 9:10work for color texture
455. 9:12and little bit for
456. 9:14normal map.
457. 9:14There is a normal.
458. 9:15Painting and motif.
459. 9:16If I want to
460. 9:17get the best possible
461. 9:18quality it means also
462. 9:19adding some nice PBR stuff.
463. 9:21And I.
464. 9:21still.
465. 9:22Have one paint software
466. 9:23in my list that
467. 9:24is hard to replace
468. 9:25but I'm really looking
469. 9:26into it.
470. 9:27It is substance painter for.
471. 9:29Materials Also can be
472. 9:30used for baking like
473. 9:32baking ambient occlusion normal
474. 9:33maps etc.
475. 9:34And going here with
476. 9:35good UV really.
477. 9:36Makes sense.
478. 9:37Without good UV you
479. 9:39might have less access
480. 9:40to all what substance
481. 9:42painter can offer.
482. 9:43Right the whole idea.
483. 9:43Here is that you
484. 9:44can define some zones
485. 9:45and quickly apply some
486. 9:47materials such as for
487. 9:49example fur material.
488. 9:50I can apply it.
489. 9:51On top of my
490. 9:52color texture and again
491. 9:53really quick it will
492. 9:54do the good job.
493. 9:55So I'm here not
494. 9:56really to do the
495. 9:58painting but.
496. 9:58More to adjust the
497. 10:00materials because overall I
498. 10:01was really happy with
499. 10:02the For some gold
500. 10:04ornaments I.
501. 10:05Did assign the material
502. 10:07here but again that
503. 10:08was like easy because
504. 10:09I got like really
505. 10:11nice UV and also
506. 10:12it's like a.
507. 10:13Really good mesh.
508. 10:14So even without UV
509. 10:15I was able to
510. 10:16just click on the
511. 10:17polygons and assign the
512. 10:19material nicely because it.
513. 10:20Is logical.
514. 10:21It's so cooler I
515. 10:22mean to work with it.
516. 10:23Okay you can spend
517. 10:24a lot of time there.
518. 10:25I'm gonna bring material
519. 10:26texture to Blender and connect.
520. 10:28Them here.
521. 10:28And also I completely
522. 10:30forgot stuff I need
523. 10:32my eyes done.
524. 10:33So I actually had to.
525. 10:35Rework a little bit
526. 10:36the eyes and the
527. 10:37good news it was
528. 10:38quite easy.
529. 10:38I just created a
530. 10:39sphere and put them
531. 10:41внутри the.
532. 10:42eye.
533. 10:42Space and generated some
534. 10:44cool texture with nano banana.
535. 10:46So here you can
536. 10:47see connected to the eye.
537. 10:48Boom!
538. 10:49I think looks so.
539. 10:50Much better right now.
540. 10:51And here's my character
541. 10:52ready to be rigged.
542. 10:53I still gonna use
543. 10:55Aku rigged to start
544. 10:56with because again.
545. 10:57Like that's just like
546. 10:58a good starting point
547. 10:59like it provides really
548. 11:00good quality.
549. 11:01So I'm gonna put
550. 11:03my character there alone.
551. 11:05Without accessories again and
552. 11:06do the rigging as
553. 11:08the previous time.
554. 11:09Now it's time to
555. 11:10assign all the accessories.
556. 11:12We're.
557. 11:12Also gonna take care
558. 11:13about stuff like tail etc.
559. 11:15Why?
560. 11:15Because we're gonna set
561. 11:16the physics.
562. 11:17So here's the final result.
563. 11:19I even.
564. 11:19Added like a small
565. 11:21bone here to do
566. 11:22the animation of this part.
567. 11:24For this scarf part.
568. 11:27I left them again
569. 11:29without the skeleton because
570. 11:30I gonna apply clothing
571. 11:32physics in Unreal Engine.
572. 11:34And the tail.
573. 11:34Of course.
574. 11:35Yeah you can see
575. 11:35like the bunch of
576. 11:36bones here and all
577. 11:38things here.
578. 11:39They also do have
579. 11:40some bones.
580. 11:41Here One, two, three, four.
581. 11:44Okay.
582. 11:45Hope you can see
583. 11:45it nicely.
584. 11:46Well I think that's enough.
585. 11:47I'm pretty happy with.
586. 11:48My character.
587. 11:49Other settings can be done.
588. 11:52Altogether at this stage
589. 11:53I spent 5 .5 hours.
590. 11:56And if you guys
591. 11:57also want to learn
592. 11:58fastest way how you can.
593. 11:59Create your own 3D
594. 12:00character combining AI tools
595. 12:02with base minimum of
596. 12:043D skills you most
597. 12:05welcome to join my 3D.
598. 12:07AI course.
599. 12:07We already have more
600. 12:08than 100 happy.
601. 12:09Students creating their characters.
602. 12:11All links will be
603. 12:12in the description.
604. 12:12And I recently also
605. 12:14launched environment course.
606. 12:15So now you can
607. 12:16create character and a
608. 12:17world for this character.
609. 12:19In Unreal Engine I
610. 12:20spent some decent amount
611. 12:22of time setting materials.
612. 12:24Because Blender materials are
613. 12:25of course not really
614. 12:27exported to Unreal Engine.
615. 12:28And I also gonna
616. 12:29use that preset for
617. 12:31this cool parkour animations.
618. 12:33Right?
619. 12:34Just retarget the animation
620. 12:35into one of the
621. 12:36character presented in this
622. 12:37template and you already
623. 12:39can run around.
624. 12:40I don't know why
625. 12:41everyone still surprised that
626. 12:42it is so easy.
627. 12:43Epic Games team actually
628. 12:44made it so easy
629. 12:45to use and But
630. 12:47that's only the moment
631. 12:48and I still have
632. 12:49to spend some time
633. 12:50assigning the physical bones.
634. 12:52I still don't get
635. 12:53it like why they
636. 12:54cannot make this tool
637. 12:55more convenient like because
638. 12:56it's really a nightmare
639. 12:57like to set all
640. 12:59these colliders right here
641. 13:00in Unreal Engine.
642. 13:01They did an update
643. 13:02to clothing however so
644. 13:04it should be easier
645. 13:05but I don't know
646. 13:05like I still sometimes
647. 13:07use the old way
648. 13:09for clothing especially if
649. 13:10I need to add
650. 13:11it like just once.
651. 13:12Maybe used to it
652. 13:13like over time.
653. 13:14But there's a new
654. 13:15workflow that allow you
655. 13:16to you know like
656. 13:17do it once and
657. 13:19reassign easily the same
658. 13:20clothing physics presets etc.
659. 13:23So count another hour
660. 13:25in Unreal Engine and
661. 13:26here we go.
662. 13:27Pretty amazing right?
663. 13:29I'm really really happy
664. 13:30like how my character
665. 13:31ended up.
666. 13:32And speaking Of my
667. 13:3310 hours title it
668. 13:34was indeed the plan
669. 13:35and I was planning
670. 13:36to use that high
671. 13:37poly to low poly
672. 13:38baking and approximately I
673. 13:40think I would end
674. 13:41up like 10 hours
675. 13:42or so.
676. 13:43But when I tested
677. 13:44retopology and compared it
678. 13:46with the P2 I
679. 13:47just changed my mind
680. 13:48and decided like I
681. 13:49better show you like
682. 13:50the faster workflow that
683. 13:52for me now works better.
684. 13:54The only case when
685. 13:55you don't want to
686. 13:56use it if you
687. 13:57have like really detailed
688. 13:59high poly that you
689. 14:00want to start with
690. 14:01and preserve a lot
691. 14:02of details like baking
692. 14:03normal maps etc.
693. 14:04That can make sense
694. 14:05and then I would
695. 14:07say okay go with
696. 14:07that longer pass.
697. 14:08Other than if you
698. 14:09have like styled characters
699. 14:11or simplified characters just
700. 14:12go with P2 like
701. 14:14low poly right away.
702. 14:15It is just amazing
703. 14:16how cool it works now.
704. 14:18That was Steph.
