3. 0:15>> Hello and welcome back everyone to
4. 0:16Unreal Engine beginner's guide to
5. 0:18building an environment. In the last
6. 0:20lesson we completed an entire shape of
7. 0:22the bridge and this time we're just
8. 0:24going to make some tweaks in regards to
9. 0:26the colors and make some adjustments to
10. 0:28the overall
11. 0:29Make sure using a material instance
12. 0:32provided within a Quixel asset itself.
13. 0:35So let's go ahead and get started. I'm
14. 0:37going to go into the 3D assets folder
15. 0:40for the Megascans and actually right
16. 0:43away I think we're going to adjust and
17. 0:45tweak out the values for these planks
18. 0:47over here. So I'm thinking about going
19. 0:49into
20. 0:51the ones that have small wood boards.
21. 0:53Let's go ahead and open that up and in
22. 0:56order for us to tweak the values over
23. 0:57here, I think before doing the tweaks,
24. 1:00we're just going to make a duplicate out
25. 1:02of the material instance itself. So
26. 1:05later on if you want to have the
27. 1:07original kind of a look that we have
28. 1:09right now, we can always set up and I
29. 1:12reassign the material instance back to
30. 1:15its default state. So by selecting it
31. 1:18and then clicking control C and control
32. 1:19V, we're able to make a duplicate out of
33. 1:21it just like that and we're just going
34. 1:23to leave it as is and I think we're just
35. 1:26going to adjust the material instance to
36. 1:28the full one that we had previously
37. 1:30right away. So if we double click on it,
38. 1:32we'll be able to open up a material
39. 1:34instance editor and we get a bunch of
40. 1:37parameters out of them.
41. 1:38So on the right side for the details
42. 1:40tab, I'm actually just going to lower
43. 1:42this down a little bit like so so we
44. 1:43could see our
45. 1:45boards of the bridge right away as is.
46. 1:49So the main ones that we want to adjust
47. 1:52is going to be within the albedo tab. If
48. 1:54we were to expand this, we'll see albedo
49. 1:58uh tint and albedo controls.
50. 2:00So, albedo tint is just a color tint
51. 2:02that we're able to adjust. If we were to
52. 2:04select in it and then click on this
53. 2:06square over here, we're able to get
54. 2:08ourselves a color picker. Now, by
55. 2:10default, if it's set to white, it means
56. 2:12that it won't be affecting the texture
57. 2:14itself and we're only going to be
58. 2:16applying a tint once we're starting to
59. 2:20darken this up. So, for example, if we
60. 2:22start to darken this entire thing up,
61. 2:23you can see how the boards are being
62. 2:25darkened up as well, which is pretty
63. 2:27nice. Not only we can darken these
64. 2:29boards, we can also change the
65. 2:30saturation, the type of tint that we're
66. 2:32having for these boards as well. So, by
67. 2:35changing them for example something like
68. 2:36green, we're going to get a greenish
69. 2:38type of a tint, which is pretty nice as
70. 2:40is.
71. 2:41So, I think
72. 2:42we're actually going to
73. 2:44go back to the default one and maybe
74. 2:46play around a little bit with
75. 2:48a
76. 2:49orange tint like so.
77. 2:52And maybe just darken it up a little bit
78. 2:54like so. So, these are the values that
79. 2:56I'm going to use.
80. 2:58We're going to make uh just a really
81. 2:59small tweak and we're going to hit okay.
82. 3:02So, we can even tick this box over here
83. 3:05and see how it looks like before it's
84. 3:07being applied. So, if you untick it and
85. 3:09then tick it back on, we can see we're
86. 3:10just applying a small bit of a tint onto
87. 3:13our planks. Now, for us to have a even
88. 3:16greater control of this overall texture,
89. 3:18what we can do is we can make use out of
90. 3:20the albedo controls. So, by ticking this
91. 3:22on and expanding this list, we see we
92. 3:25have a bunch of different options for us
93. 3:27to use. Things like saturation,
94. 3:30brightness, contrast. We can make use
95. 3:32out of all of them and of course, just
96. 3:35as the name suggests, by changing the
97. 3:37saturation, clicking and holding and
98. 3:38then dragging to the left or right,
99. 3:40we're able to change the saturation of
100. 3:43these boards. And of course, the
101. 3:44brightness goes the same kind of way.
102. 3:46And we're going to be changing that up
103. 3:49and darkening the down a little bit,
104. 3:51changing the saturation a little We're
105. 3:52going to change it to 0.7 like so.
106. 3:55Changing the brightness to be a little
107. 3:58bit darker. I think this is going to be
108. 4:00much nicer. Actually, let's try Yeah,
109. 4:02let's go ahead and darken it down a
110. 4:05little bit. And then let's play around
111. 4:07with the contrast maybe a little bit.
112. 4:09Or actually, because we're changing
113. 4:11contrast,
114. 4:12we're going to change this to 0.85. I
115. 4:15think that's going to be a nice value.
116. 4:16And we're going to increase the
117. 4:17saturation back up. I think it's going
118. 4:19to look much nicer. So,
119. 4:22let's go ahead and change the saturation
120. 4:24to 0.8. And we're already getting some
121. 4:26nice results, but I think it's too
122. 4:27bright. But even if we were to change
123. 4:29the darkness, we're not going to get
124. 4:31quite as nice a result. So, I think I'm
125. 4:32going to go back onto the tint and
126. 4:35darken this down a little bit more.
127. 4:37And increase the saturation over like
128. 4:39this. Like so. And I think that's going
129. 4:41to give us some really nice results. So,
130. 4:43maybe we want to make it a little bit
131. 4:45more brownish.
132. 4:46Like so.
133. 4:49That's going to look quite nice.
134. 4:52Darken it down a little bit.
135. 4:54And we're just making sure that all of
136. 4:55these planks have more or less the same
137. 4:57kind of a tint applied throughout this
138. 4:59entire texture. So, it's just going to
139. 5:01look like it's more part of the right
140. 5:03kind of result. We also have something
141. 5:05called NA, which of course doesn't do
142. 5:06anything. So, we can just going to leave
143. 5:08it as a zero. And the brightness
144. 5:11actually going to play around a little
145. 5:13bit with the brightness. Maybe lower
146. 5:14this down even to a value of 0.4.
147. 5:17And maybe just maybe it's going to look
148. 5:19quite nice.
149. 5:21Now, as you can see, there's one board
150. 5:23that's actually going to look a little
151. 5:24bit too dark and one that is going to
152. 5:26look too bright. So, I think we're going
153. 5:28to close this down and we're going to
154. 5:30apply the original material instance
155. 5:33that we had back onto those boards
156. 5:35because they stand out a little bit too
157. 5:36much, I reckon. So, what we're going to
158. 5:38do is the easiest way to apply them is
159. 5:40by simply dragging and dropping them
160. 5:42onto those boards like so. We're going
161. 5:43to get its original default kind of a
162. 5:45color. So, actually I'm just going to
163. 5:47drag it onto the
164. 5:49one that's the darkest, and that's going
165. 5:51to give us actually some real nice
166. 5:52results.
167. 5:53Just going to drag this one over here.
168. 5:56Going to click control Z because I mis-
169. 5:58misaligned it, and there you go.
170. 6:01We're able to brighten this up. Now, if
171. 6:03we want to darken these ones down a
172. 6:06little bit even more, just to make it
173. 6:08suit more suitable, we're going to make
174. 6:10a duplicate out of the one that we
175. 6:12adjusted out of these values. So, we're
176. 6:14going to make a third material instance
177. 6:17just like that.
178. 6:18And we're going to actually
179. 6:20make this a little bit darker. So, we're
180. 6:23going to go into this
181. 6:25material instance, and we're going to
182. 6:27lower the brightness.
183. 6:30And by setting this up to value of 0.2,
184. 6:33I think it's going to look all right.
185. 6:34We're going to now close this down.
186. 6:35We've got a much darker variation. So,
187. 6:37now if we apply this onto this plank, we
188. 6:39can see the difference that it's going
189. 6:41to make. And this way, we're able to
190. 6:43have a lot of control over color
191. 6:45textures, and have a really really nice
192. 6:48results of the overall type of a look
193. 6:50for our boards. So, I think it's already
194. 6:54looking pretty nice.
195. 6:56But, I don't quite like the way these
196. 6:59are looking. So, I think we're going to
197. 7:01be changing them up a little bit, the
198. 7:03beams themselves.
199. 7:05So, let's go into the 3D assets. Let's
200. 7:07go into the wooden beam and adjust
201. 7:09material instance. And just like we did
202. 7:11previously, we're going to click control
203. 7:13C, control V to make a duplicate of the
204. 7:15default one, and we're going to maybe
205. 7:18change up the boards right away. But,
206. 7:21now that I think about it, we might be
207. 7:24using them for our
208. 7:26house. And I think
209. 7:29Yeah, I think if we were to change that
210. 7:31up, the default material instance that's
211. 7:33assigned onto the default static mesh,
212. 7:36the next time we're going to be dragging
213. 7:37this out, we'll have the adjusted
214. 7:40values. So, instead what I'd like us to
215. 7:41do is I like us to make a different
216. 7:44assigned material instance. So, right
217. 7:46now we have a material the original one
218. 7:49and the material instance the copy of
219. 7:51it. So, now we're going to click on one
220. 7:54of the poles and see the name in the
221. 7:56outliner. And we can see that if I were
222. 7:59to extend it a little bit,
223. 8:01we can see that it is named the worn
224. 8:03wooden beam. And because it's in
225. 8:05alphabetical order, all of these worn
226. 8:08wooden beams are going to be in exactly
227. 8:10the same order. So, what we need to do
228. 8:12is simply click on the first one that's
229. 8:14named like this and then scroll all the
230. 8:16way down and while holding shift, click
231. 8:20on the last one and this way we should
232. 8:22grab all of them at once. So, if I were
233. 8:24to just drag them out, you can see that
234. 8:26all of them are being moved to the side.
235. 8:28And because we selected all of them and
236. 8:30because they are the same asset, they're
237. 8:32the instances of the same asset, we're
238. 8:34going to have within the details tab
239. 8:36more or less the same kind of results.
240. 8:37So, materials, you can see that all of
241. 8:40them are being assigned one material. If
242. 8:42we have something additional selected,
243. 8:43for example, I'm going to click while
244. 8:45holding shift, going to click on this
245. 8:47plank over here, we can see that the
246. 8:49material is going to change with two
247. 8:51materials selected. But even so, if we
248. 8:53were to
249. 8:55click on display two materials, we're
250. 8:56going to see these elements being shown.
251. 8:59So, what we need to do is just simply
252. 9:01make sure we replace the original
253. 9:03material instance with the material that
254. 9:07we made a copy out of. So, right now
255. 9:09this is the original one. I know that it
256. 9:11has the same look, so I know that it is
257. 9:13the same one. All we got to do is
258. 9:16drag the copy into this element like so
259. 9:19and we're going to have a replacement
260. 9:21out of them just like that.
261. 9:25And let me just have a look. I think I
262. 9:27made a mistake. Going to click from lit
263. 9:30to unlit just to make sure I see the
264. 9:32albedo map a little bit more the color
265. 9:34information and actually seems like
266. 9:36we're having some artifacts And I
267. 9:38believe the reason for it is because
268. 9:40this is not the same wooden beam that I
269. 9:42was using. So, let me just have a look
270. 9:43real quick. I'm going to drag this
271. 9:45outwards and I can see that it is a
272. 9:46complete different wooden beam. So, I'm
273. 9:48just going to click control Z and go
274. 9:50back to its original values.
275. 9:53And actually just going to delete this
276. 9:55material instance and click delete
277. 9:57because we weren't using it. It's just
278. 9:59going to prompt up with a simple delete
279. 10:01window. And then we're going to go back
280. 10:04onto the 3D assets and find ourselves
281. 10:07the right one. So, small wood boards.
282. 10:09Oh, sorry. It's because we have this
283. 10:11selected. Just going to untick it. It's
284. 10:13going to be called worn wooden beam. So,
285. 10:16it's going to be the last one over here.
286. 10:19Worn wooden beam. Let's go ahead and
287. 10:21open it up. Again, I made sure I click
288. 10:23control Z to undo my step. I still have
289. 10:26all of this selected and I'm just going
290. 10:28to go get the material instance selected
291. 10:31within the content browser. Click
292. 10:33control C, control V, make a duplicate
293. 10:35out of it. Now we have a material
294. 10:37instance copy out of it.
295. 10:39And we're going to drag this into the
296. 10:41material that we have that is basically
297. 10:44looking exactly the same as this icon
298. 10:45over here. So, we're just going to click
299. 10:47and drag and drop it into this material
300. 10:50like so. And we pretty much replace it.
301. 10:52Although, we're not going to be be
302. 10:54seeing a much of a difference right now
303. 10:55because we didn't actually make any
304. 10:57tweaks to the material instance. So,
305. 10:59let's go ahead and do that right away
306. 11:00actually. We're going to open this
307. 11:02material instance like so.
308. 11:04We're going to click albedo tint and
309. 11:06albedo controls and we're going to play
310. 11:08around with values a little bit. So,
311. 11:10we're going to make sure that albedo
312. 11:11controls have this entire tab opened up.
313. 11:15Albedo tint though can have it closed
314. 11:18down. And we're just going to play
315. 11:20around with the values right away. I
316. 11:21think I'm just going to try darkening
317. 11:23darkening this down a little bit and see
318. 11:25how this looks and
319. 11:28maybe it's not being affected. Just want
320. 11:30to see what is up with that. Going to
321. 11:32close this down, see if they're being
322. 11:34applied.
323. 11:35And I think they're being applied. Just
324. 11:36going to make sure that they're being
325. 11:39attached to this like so. And it seems
326. 11:42like I need to make sure I have them all
327. 11:44selected again.
328. 11:46And reattach them just like that. And
329. 11:48now this is going to work. So I just
330. 11:49made sure I reselect remake my selection
331. 11:53and then attach it the material onto it
332. 11:56just like that. And now it seems to make
333. 11:58a proper assignment onto the material
334. 12:01instance.
335. 12:02So now we can open this up and make some
336. 12:03tweaks. And by tweaking this around, we
337. 12:06can see that it is making the changes
338. 12:08that we want. So I'm just going to make
339. 12:10it a little bit brownish and darken it
340. 12:12up a little bit more like so.
341. 12:14And click okay.
342. 12:16Then I'm thinking maybe just maybe
343. 12:19I'm going to actually adjust the
344. 12:21roughness values for this as well.
345. 12:23Because by default, this wood looks
346. 12:25quite a bit dried up. And obviously
347. 12:27because it's going to be next to the
348. 12:28water, we probably don't want this kind
349. 12:30of a result. So we're going to actually
350. 12:32go and make additional tweaks to it. So
351. 12:34by scrolling down, we actually have
352. 12:37roughness value over here. And by
353. 12:39enabling these both like so,
354. 12:41by default it's going to be one and
355. 12:43zero. And this is just like a clamp sort
356. 12:46of a value. So the maximum result for
357. 12:49how rough the value is going to be. If
358. 12:51we lower this down, we're going to get a
359. 12:53much shinier result. Alternatively, if
360. 12:56we increase this value the minimum
361. 12:57roughness,
362. 12:58we'd get a much a rougher type of a
363. 13:01value. So
364. 13:03we're going to actually only
365. 13:04decrease the maximum roughness value
366. 13:07from one. We're going to change it maybe
367. 13:09to 0.5. Let's go ahead and see how this
368. 13:10looks. And maybe it's a little bit too
369. 13:12much though. We don't want it to overdo
370. 13:14it. So 0.8. And I think Yeah, I think
371. 13:17that's just looking much better as is.
372. 13:19We're going to keep it as is actually.
373. 13:21This is looking quite nice. So let's go
374. 13:23ahead and leave it as is. Maybe actually
375. 13:27we need to lower the contrast. I'm going
376. 13:30to try to lower the contrast a little
377. 13:31bit just to see how it looks like.
378. 13:33And just by lowering just a little bit,
379. 13:36we might get some nicer results.
380. 13:39But it's again, it's just a matter of
381. 13:41preference how it's going to look like.
382. 13:43For now, I think we're going to keep it
383. 13:45as a value of one, and we're just going
384. 13:47to leave it as it is. And worst case, in
385. 13:49the future, we might just come back to
386. 13:51it and see how that looks.
387. 13:53And actually,
388. 13:55we might, because we we changed up the
389. 13:57roughness value, we're going to get a
390. 13:58different type of a light bounce on
391. 14:00these
392. 14:01areas. And I think we should probably
393. 14:04increase the brightness just a little
394. 14:05bit.
395. 14:07Like so, to value 1.2.
396. 14:091.2, like so.
397. 14:11And now we're going to get some real
398. 14:13nice results, maybe even 1.4.
399. 14:16Yeah, I think 1.4 is going to be quite
400. 14:18nice. We don't want it to get the exact
401. 14:19same value as the planks on the top. We
402. 14:21just want to have it look like it's part
403. 14:24of the same atmosphere, the same
404. 14:26environment, but at same time it's made
405. 14:28out of different type of wood, because
406. 14:29these are planks and these ones are kind
407. 14:31of like logs that were used to build
408. 14:34this bridge.
409. 14:35So, finally, I think we're going to just
410. 14:37switch up these planks as well, and for
411. 14:40the ones that are here, they're quite
412. 14:41light. I think we're going to keep them
413. 14:43as quite light, because they're just
414. 14:45going to look so much nicer, and they're
415. 14:46just going to stand out so much more.
416. 14:48And worst case, we can come back to it
417. 14:50and switch them around a little bit. But
418. 14:53yeah, for now, let's just go ahead and
419. 14:54switch these planks up. So, we're just
420. 14:55going to select this plank. We're going
421. 14:57to close down the instant bro- uh
422. 15:00material browser that we had previously,
423. 15:03and select the plank that's underneath.
424. 15:06Going to click on this button over here.
425. 15:09And by simply clicking on this, we're
426. 15:11able to go straight into the folder for
427. 15:13where this material instance is located.
428. 15:17So, now we're going to make a copy out
429. 15:18of it. Control C, control V, make a
430. 15:20duplicate.
431. 15:21Select the wooden beam that we had. We
432. 15:23can see that the names, because it's in
433. 15:26alphabetical order, we have three of
434. 15:27them. We're going to select all three of
435. 15:29them and apply our material instance
436. 15:32that we just made a copy out of it. You
437. 15:34can see that the name has changed, so
438. 15:35that's good. Now we can go into this
439. 15:37material instance and change up the
440. 15:39tint. We can click on it,
441. 15:42make it darker quite a bit like so,
442. 15:45make it browner even,
443. 15:47like so.
444. 15:49And let's have a look.
445. 15:51I think we need to make it look
446. 15:53roughened up. It looks too plain at the
447. 15:54moment, so I'm going to increase the
448. 15:57contrast for this one
449. 15:59by quite a bit by just increasing it to
450. 16:00a value of 0.8 maybe,
451. 16:02maybe 0.6 1.6.
452. 16:05Like so and it's going to give us some
453. 16:07nice results right away. I think that's
454. 16:09going to look quite nice.
455. 16:10So, yeah. And maybe just saturation,
456. 16:13remove that a little bit.
457. 16:14Otherwise it just looks a little bit too
458. 16:16much.
459. 16:17And that's all there is to it to be able
460. 16:20to tweak all of these values. So, it's
461. 16:22already looking quite nice. Maybe we
462. 16:23should adjust these a little bit and
463. 16:26make them look a little bit darker
464. 16:28in regards to the overall design. Now
465. 16:31going back to it,
466. 16:32but yeah, okay. Let's leave it as it is
467. 16:35for now and in the next lesson we're
468. 16:37going to continue building up our
469. 16:38environment. This time we're actually
470. 16:39going to start on creating the house
471. 16:43area over here. So, thank you so much
472. 16:46for watching and I'll see you in a bit.
