252 00:13:28,912 --> 00:13:31,049 It is indeed. 253 00:13:31,049 --> 00:13:36,759 So let's go back to my 254 00:13:37,961 --> 00:13:39,897 and then scale these up by, 255 00:13:39,897 --> 00:13:42,902 let's say ten times and 256 00:13:45,774 --> 00:13:48,779 where's my panel gone? 257 00:13:52,084 --> 00:13:52,986 Let's just do it here. 258 00:13:52,986 --> 00:13:55,957 That's fine. 259 00:14:00,164 --> 00:14:03,169 And it's too soon for the other one. 260 00:14:08,578 --> 00:14:11,583 These are transforms and export them again. 261 00:14:12,452 --> 00:14:15,457 Sorry, one at a time, 262 00:14:18,428 --> 00:14:21,400 and then the other one 263 00:14:21,867 --> 00:14:22,435 falling leaf. 264 00:14:22,435 --> 00:14:24,505 Large 265 00:14:24,505 --> 00:14:27,677 crates now back in engine re-import those two. 266 00:14:27,677 --> 00:14:30,682 So you just select them, right click them, re-import, 267 00:14:32,084 --> 00:14:35,089 that's a bit better. 268 00:14:37,360 --> 00:14:40,365 Still going to be a little bit small. 269 00:14:42,067 --> 00:14:43,570 Might look fine when they're falling. 270 00:14:43,570 --> 00:14:45,306 No, let's go for another ten. 271 00:14:45,306 --> 00:14:48,311 So I mean, we could have done it by 100. 272 00:14:52,184 --> 00:14:54,789 That's to leave those 273 00:14:54,789 --> 00:14:56,191 and go up and send 274 00:15:19,864 --> 00:15:20,966 sweet. 275 00:15:20,966 --> 00:15:23,971 So let's re-import those again. 276 00:15:24,939 --> 00:15:27,276 Are we looking now. 277 00:15:27,276 --> 00:15:30,281 Super huge 278 00:15:30,448 --> 00:15:33,453 but closer to what we see 279 00:15:33,987 --> 00:15:36,124 on the tree, 280 00:15:36,124 --> 00:15:37,059 which is fine. 281 00:15:37,059 --> 00:15:39,797 You tweak that down a little bit once we get them into the M, 282 00:15:39,797 --> 00:15:42,101 once we get them into the emitter. So that's cool. 283 00:15:42,101 --> 00:15:43,637 At least they kind of match the tree now. 284 00:15:43,637 --> 00:15:46,775 But I think it's going to look a bit mental, having huge branches 285 00:15:46,775 --> 00:15:49,747 falling through the sky. 286 00:15:50,147 --> 00:15:51,349 So now we've done that. 287 00:15:51,349 --> 00:15:54,688 What we need to do is start to set up a particle system 288 00:15:58,094 --> 00:15:59,596 and to do that, 289 00:15:59,596 --> 00:16:02,601 basically what we need to do is 290 00:16:03,202 --> 00:16:06,608 just create a new Niagara system. 291 00:16:07,042 --> 00:16:10,548 And basically all you do to do that is if we go into our effects folder 292 00:16:10,548 --> 00:16:15,924 and right click and then go to Effects and then go to Niagara system here 293 00:16:16,925 --> 00:16:18,027 we can just use 294 00:16:18,027 --> 00:16:22,167 a new system from selected admins. 295 00:16:22,167 --> 00:16:24,805 So you can choose a mix of emitters 296 00:16:24,805 --> 00:16:28,745 and templates, or you can do a new system from a template copy 297 00:16:28,745 --> 00:16:31,750 existing system that you really set up or create a completely empty one. 298 00:16:31,884 --> 00:16:34,889 So for this, what we're going to do is just do new system from a template 299 00:16:36,024 --> 00:16:38,995 and it's next. 300 00:16:38,995 --> 00:16:42,301 And then I think probably 301 00:16:43,503 --> 00:16:45,573 the easiest one for us to do to use 302 00:16:45,573 --> 00:16:48,578 this from is just directional burst. 303 00:16:48,745 --> 00:16:51,750 We're just going to have them floating down from the sky. 304 00:16:51,817 --> 00:16:54,822 So let's just do that one and then let's call it 305 00:16:54,822 --> 00:16:58,094 falling Leaves Effects. 306 00:17:01,099 --> 00:17:02,468 So when it opens up, 307 00:17:02,468 --> 00:17:06,341 what you have is this window, which looks exactly the same as the asset 308 00:17:06,374 --> 00:17:09,446 you are really, except it's got some additional parts. 309 00:17:10,181 --> 00:17:11,917 You've got this workspace over here 310 00:17:12,952 --> 00:17:14,989 which has like a it's called the System Overview. 311 00:17:14,989 --> 00:17:18,762 And then basically it looks the same as kind of the node view of for materials 312 00:17:18,762 --> 00:17:22,501 or since the blueprint layouts look like this as well. 313 00:17:24,538 --> 00:17:26,541 But what we'll do is most of our work in here 314 00:17:26,541 --> 00:17:28,444 and then you have your viewer over here to the left, 315 00:17:28,444 --> 00:17:32,585 you can move around it in the same way that you would do the one in for the asset 316 00:17:32,585 --> 00:17:35,723 so you can move the light around and you can also move around it 317 00:17:35,723 --> 00:17:38,628 by holding left click and then you move the light around with L 318 00:17:38,628 --> 00:17:41,900 you have this timeline down the bottom, which is useful that plays 319 00:17:41,900 --> 00:17:44,972 your particle system over and over and over. 320 00:17:46,474 --> 00:17:50,448 And that's pretty much what we'll need to use just now. 321 00:17:50,748 --> 00:17:54,187 And you can compile and save it here and then you can also look at the 322 00:17:54,187 --> 00:17:54,888 performance of it. 323 00:17:54,888 --> 00:17:58,595 If you press performance, it tells you here what's going on. 324 00:18:00,631 --> 00:18:02,000 So what we're going to do 325 00:18:02,000 --> 00:18:05,005 really is just start working with this 326 00:18:05,206 --> 00:18:08,745 and turning it from this into falling leaves with some direction to them. 327 00:18:09,179 --> 00:18:10,514 So I'll walk you through that. 328 00:18:10,514 --> 00:18:14,554 And yeah, we should, we should have something looking quite cool in the end. 329 00:18:15,022 --> 00:18:15,823 So the first things that 330 00:18:15,823 --> 00:18:18,828 we don't want to do is just delete off this location based ribbon. 331 00:18:18,828 --> 00:18:21,700 You can see that's what's creating these, 332 00:18:21,700 --> 00:18:23,870 these like tails on the particles. 333 00:18:23,870 --> 00:18:24,938 We don't need those. 334 00:18:24,938 --> 00:18:27,776 So you can just delete those, just delete those out. 335 00:18:27,776 --> 00:18:29,246 That's fine. 336 00:18:29,246 --> 00:18:31,716 And where we want to start 337 00:18:31,716 --> 00:18:34,721 is an emitter update. 338 00:18:37,526 --> 00:18:39,162 We can start here, I suppose. 339 00:18:39,162 --> 00:18:42,033 Yeah, let's start, let's start at the top and then work our way downwards. 340 00:18:42,033 --> 00:18:45,473 So in here there are all a bunch of different 341 00:18:45,473 --> 00:18:48,478 settings or things that you can do to particles. 342 00:18:48,478 --> 00:18:51,483 You can then also if you press the plus button, 343 00:18:51,516 --> 00:18:54,020 add things extra so you can type like wind 344 00:18:55,389 --> 00:18:57,159 and you can add in a wind force. 345 00:18:57,159 --> 00:18:59,930 There are a whole bunch of different things that we can add in here. 346 00:18:59,930 --> 00:19:02,267 I'll not go through all of them, but it's in similar 347 00:19:02,267 --> 00:19:06,007 in ways to the things that you can add in blueprints or in the material system. 348 00:19:06,274 --> 00:19:08,411 There's just loads of different things that you can put in here. 349 00:19:08,411 --> 00:19:11,750 If you press the plus button, it will give you what things you can add. 350 00:19:11,750 --> 00:19:13,619 So you can just have a flick through these 351 00:19:13,619 --> 00:19:16,157 and see what all of the different things do. 352 00:19:16,157 --> 00:19:19,696 They'll be in context, so you won't be able to add things that don't work. 353 00:19:19,696 --> 00:19:23,169 So the stuff that you can add to spawn, you can see that list has gotten smaller 354 00:19:23,502 --> 00:19:26,207 to the list that I can add here. 355 00:19:26,207 --> 00:19:28,077 So these will all do something. 356 00:19:29,179 --> 00:19:29,513 Some of 357 00:19:29,513 --> 00:19:33,352 them play audio, things like that so you can have a flick through those. 358 00:19:33,352 --> 00:19:36,758 What I'll do is just to stop it from becoming too complex too quickly. 359 00:19:37,259 --> 00:19:41,065 I'll work through what it is that we need to do to get the result 360 00:19:41,332 --> 00:19:45,673 and then hopefully you'll pick up kind of what you can do from there. 361 00:19:45,673 --> 00:19:50,314 And then if you'd like to create different systems, then go on from there. 362 00:19:50,314 --> 00:19:53,285 But you should gain a base understanding of kind of what's going on here. 363 00:19:53,419 --> 00:19:56,357 It is all named for you, which is the best thing. 364 00:19:56,357 --> 00:19:58,060 So this all make sense to some degree. 365 00:19:58,060 --> 00:20:00,765 There are some things in here that baffle me. 366 00:20:00,765 --> 00:20:03,669 Unless you're an artist, I imagine they will do, 367 00:20:03,669 --> 00:20:06,574 but it's fairly simple to try and work out 368 00:20:06,574 --> 00:20:10,113 and get something going, which is what I did here to make the system work. 369 00:20:10,113 --> 00:20:12,584 So yeah, let's start off at Mr. 370 00:20:12,584 --> 00:20:15,589 Update and we want the loop 371 00:20:15,589 --> 00:20:18,694 behavior to be infinite so that it just keeps going forever. 372 00:20:18,694 --> 00:20:19,997 And it doesn't just happen once, 373 00:20:21,032 --> 00:20:21,566 which is what we 374 00:20:21,566 --> 00:20:24,571 want, and then set the loop duration. 375 00:20:24,571 --> 00:20:27,576 So this is a duration of the lifecycle. 376 00:20:27,876 --> 00:20:29,446 So how long? 377 00:20:29,446 --> 00:20:33,719 So this is going like 1111. 378 00:20:34,354 --> 00:20:37,325 So if we set this to two, 379 00:20:37,826 --> 00:20:42,434 one and two on and to set fires off 380 00:20:43,569 --> 00:20:45,572 every that amount of seconds. 381 00:20:45,572 --> 00:20:47,976 So I think we're right at leaving it for two. 382 00:20:47,976 --> 00:20:50,748 And then the spawn count, 383 00:20:50,748 --> 00:20:53,218 sorry, not the spawn count, 384 00:20:53,218 --> 00:20:56,223 let's go for, 385 00:21:02,668 --> 00:21:05,606 let's go for, 386 00:21:05,606 --> 00:21:07,509 let's go for a number like. 387 00:21:07,509 --> 00:21:08,611 Yeah. 388 00:21:08,611 --> 00:21:11,616 Well you can see if you put in 100 and it's going to spawn 389 00:21:12,284 --> 00:21:15,289 100 of them, you put in one, it's going to shoot one. 390 00:21:15,622 --> 00:21:18,394 So let's put in 391 00:21:18,394 --> 00:21:21,432 24 now and see how that goes. 392 00:21:21,432 --> 00:21:24,437 We could add in more later, That's fine. 393 00:21:24,571 --> 00:21:26,574 So after that, 394 00:21:28,344 --> 00:21:30,447 the rest of this is not super necessary. 395 00:21:30,447 --> 00:21:33,452 Let's move down to particles four. 396 00:21:33,853 --> 00:21:36,758 So in here, this is the lifetime in the lifetime, 397 00:21:36,758 --> 00:21:39,763 max, of the of the particles. 398 00:21:39,763 --> 00:21:41,265 And that set randomly. 399 00:21:41,265 --> 00:21:42,634 So we can set two numbers. 400 00:21:42,634 --> 00:21:46,808 You can put like ten and 15, and those particles will last 401 00:21:46,808 --> 00:21:51,315 for 10 seconds and a minimum of 10 seconds and a maximum of ten of 15 seconds. 402 00:21:51,983 --> 00:21:55,956 And that's useful because our leads are going 403 00:21:55,956 --> 00:21:59,896 to kind of float around through the air and down towards the ground. 404 00:21:59,896 --> 00:22:00,564 So we'll need them 405 00:22:00,564 --> 00:22:04,571 to have an amount of time on their life that's bigger than what was there. 406 00:22:04,571 --> 00:22:07,576 Otherwise they'll just disappear as they're kind of floating through the air, 407 00:22:07,709 --> 00:22:10,714 which is not what you want. 408 00:22:11,515 --> 00:22:13,485 And then after that, 409 00:22:15,322 --> 00:22:17,258 let's just have a scroll down through here 410 00:22:17,258 --> 00:22:20,263 and see what we need to set next. 411 00:22:22,567 --> 00:22:24,337 What do we need to set next? 412 00:22:24,337 --> 00:22:27,475 Okay, so we need to add a few things here. 413 00:22:27,943 --> 00:22:31,616 What we want to do is delete the add velocity in code. 414 00:22:31,649 --> 00:22:34,654 Let's keep initialize particle because we need that one. 415 00:22:35,656 --> 00:22:38,995 And then let's add in add velocity. 416 00:22:40,063 --> 00:22:43,068 We don't need to add velocity and current, so we add velocity and 417 00:22:43,168 --> 00:22:45,739 and this is going to add our velocity. 418 00:22:45,739 --> 00:22:49,078 And then over here in this little chain bit, 419 00:22:49,445 --> 00:22:52,417 click that and then you want to just type 420 00:22:53,485 --> 00:22:55,188 random range vector 421 00:22:55,188 --> 00:22:57,959 and then this will give us a minimum and maximum so that we can find 422 00:22:57,959 --> 00:23:01,165 a random range in between these values and then add that to it. 423 00:23:02,934 --> 00:23:04,504 And what we want to throw in here 424 00:23:04,504 --> 00:23:10,247 are the five 425 00:23:11,849 --> 00:23:15,555 lines, 73. 426 00:23:21,966 --> 00:23:22,267 Okay. 427 00:23:22,267 --> 00:23:25,238 So there's a bit of variation going on there, which is what we want. 428 00:23:25,372 --> 00:23:29,211 And then next, what we want to do is apply 429 00:23:30,246 --> 00:23:32,517 initial forces 430 00:23:32,517 --> 00:23:35,355 and then just leave that as is 431 00:23:35,355 --> 00:23:36,757 initial mesh orientation. 432 00:23:36,757 --> 00:23:37,959 So we get some rotation on that. 433 00:23:37,959 --> 00:23:40,964 So let's try that. 434 00:23:43,502 --> 00:23:46,507 Sorry, not rotation, but position 435 00:23:47,375 --> 00:23:49,145 and then we're going to leave that one as it is 436 00:23:49,145 --> 00:23:52,116 and then go to what do we want to do next. 437 00:23:53,552 --> 00:23:56,557 Yeah, at some rotational, 438 00:23:59,161 --> 00:24:02,166 rotational velocity 439 00:24:02,934 --> 00:24:05,939 and two to getting. 440 00:24:07,108 --> 00:24:09,412 So I had something in here as well. 441 00:24:09,412 --> 00:24:12,417 So for a random range vector 442 00:24:12,417 --> 00:24:15,422 on that as well, 443 00:24:17,993 --> 00:24:19,161 let's 444 00:24:19,161 --> 00:24:22,166 keep this 1.5 445 00:24:24,170 --> 00:24:27,175 and then do the opposite. 446 00:24:33,318 --> 00:24:36,624 And then in sorry, in the orientation one above, 447 00:24:36,624 --> 00:24:40,363 let's add some rotation there as well to the mesh and then give that, 448 00:24:41,398 --> 00:24:43,301 let's give that to 449 00:24:43,301 --> 00:24:45,906 and I should go up, let's add a 450 00:24:45,906 --> 00:24:47,909 random range there 451 00:24:47,909 --> 00:24:50,914 to the opposite. 452 00:24:54,386 --> 00:24:57,625 And then what we want to do as a final thing in particle spawn. 453 00:24:57,625 --> 00:25:01,799 So this is doing things to the particles, adding some position 454 00:25:01,799 --> 00:25:06,139 and some position on the orientation and some rotational velocity as well. 455 00:25:06,139 --> 00:25:09,178 You can't really see it too much because these are just dot particles. 456 00:25:09,178 --> 00:25:12,183 But when you have a mesh on it, you begin to see things happen. 457 00:25:12,250 --> 00:25:17,358 What we want to do lastly is just add on a a box 458 00:25:18,393 --> 00:25:20,797 location, which is going to set them. 459 00:25:20,797 --> 00:25:23,268 So at the moment they're all kind of dropping out of a point. 460 00:25:23,268 --> 00:25:26,540 And when we set the box or you can see that sphere as well, 461 00:25:27,007 --> 00:25:30,780 it's going to drop them out from points all over that box depending on the size 462 00:25:30,780 --> 00:25:31,949 that you give the box. 463 00:25:31,949 --> 00:25:35,789 So if we go to box location, you can also do a grade as well. 464 00:25:36,957 --> 00:25:37,659 You can see now 465 00:25:37,659 --> 00:25:40,664 they're all kind of coming out of this grid. 466 00:25:40,797 --> 00:25:45,505 So what we want to do now is just go to give this a size as well 467 00:25:46,206 --> 00:25:50,513 and to just think in a public we want to make this let's try thousand 468 00:25:50,947 --> 00:25:53,952 the now. 469 00:25:57,458 --> 00:25:58,159 Okay. 470 00:25:58,159 --> 00:26:01,164 So you can see they're kind of falling from the sky now, which is nice. 471 00:26:04,503 --> 00:26:06,139 This is near what we want to happen. 472 00:26:06,139 --> 00:26:08,042 It's kind of like a light rain. 473 00:26:08,042 --> 00:26:09,879 So it's not exactly what we want to happen. 474 00:26:09,879 --> 00:26:12,416 And now before we start to look at particle up there, 475 00:26:12,416 --> 00:26:15,421 I think what we should do is add in our 476 00:26:16,924 --> 00:26:20,396 add in our mesh so that we can see what's happening in particle up there 477 00:26:20,396 --> 00:26:24,370 because this is where we'll start adding things like rotation and stuff to it 478 00:26:24,370 --> 00:26:26,707 so that you'll see them kind of floating around in the air. 479 00:26:26,707 --> 00:26:29,612 And to see that working properly, you need to have the geometry on it. 480 00:26:29,612 --> 00:26:32,383 So you can see down at the bottom under where it says render, We've got 481 00:26:32,383 --> 00:26:34,754 Sprite render at the moment and we don't want Sprite render 482 00:26:34,754 --> 00:26:36,690 because that's just going to render sprites, 483 00:26:37,925 --> 00:26:39,996 which is those little white dots that you can see. 484 00:26:39,996 --> 00:26:44,136 But what we want to render are if we delete that sprite render, 485 00:26:44,203 --> 00:26:47,208 you see everything will be gone here if we're going to plus. 486 00:26:47,742 --> 00:26:50,213 And then you can see that the context is changed here 487 00:26:50,213 --> 00:26:53,485 so that you can only get these things you can put in mesh render. 488 00:26:54,553 --> 00:26:58,293 So this will allow us to render meshes where those particles were being spawned. 489 00:26:58,827 --> 00:27:02,900 So next you just go over here to mesh rendering and then hit the plus button 490 00:27:03,268 --> 00:27:06,306 and we'll be able to add in a mesh to it. 491 00:27:07,074 --> 00:27:09,378 So to do this we want to do is 492 00:27:09,378 --> 00:27:12,416 just go and find our way. 493 00:27:12,416 --> 00:27:13,451 Did we have them in mesh? 494 00:27:13,451 --> 00:27:16,590 Find our falling leaf, click back and then just hit the use button. 495 00:27:17,024 --> 00:27:19,461 The use button. Sorry. And now you see we have 496 00:27:20,797 --> 00:27:23,167 many falling leaves. 497 00:27:23,167 --> 00:27:24,637 What you can do at this point as well. 498 00:27:24,637 --> 00:27:25,705 Now you can see the leaves. 499 00:27:25,705 --> 00:27:28,710 If you browse to your particle hammer, 500 00:27:29,378 --> 00:27:32,884 we can throw that in and now you can see all of these leaves 501 00:27:33,952 --> 00:27:36,723 dropping terribly like this, 502 00:27:36,723 --> 00:27:39,695 maybe put up a bit higher so you can see it. 503 00:27:46,005 --> 00:27:48,209 Okay, 504 00:27:48,209 --> 00:27:50,580 let's pull this over here as well. 505 00:27:50,580 --> 00:27:53,318 So the first thing that you see is maybe we shouldn't 506 00:27:53,318 --> 00:27:57,391 have scaled them up so big in the mesh, but you can drop that down here. 507 00:27:57,391 --> 00:28:00,396 Let's change into like 0.3. 508 00:28:01,331 --> 00:28:04,236 So that's just scaling the size of the mesh in render 509 00:28:04,236 --> 00:28:07,241 and then mesh render, just scaling that there. 510 00:28:08,944 --> 00:28:11,915 Now they are much smaller 511 00:28:12,616 --> 00:28:15,621 falling from the sky like leaves, 512 00:28:17,124 --> 00:28:19,294 which is awesome. 513 00:28:19,294 --> 00:28:22,500 Okay, so now we want to start adding stuff to particle updates. 514 00:28:22,500 --> 00:28:26,306 So this will be where you put in kind of what happens to you. 515 00:28:26,306 --> 00:28:29,077 Can you can already see that they're falling in different rotations 516 00:28:29,077 --> 00:28:32,349 and orientations and that's because of what we added in up here. 517 00:28:33,117 --> 00:28:37,658 But what we're going to do now is adding things that allow the particles 518 00:28:37,658 --> 00:28:41,197 or the little meshes to rotate as they're falling and stuff like that. 519 00:28:41,631 --> 00:28:43,535 So I think the first thing that we're going to want to do really 520 00:28:43,535 --> 00:28:47,040 is change the gravity, because right now it's moving too quickly. 521 00:28:47,408 --> 00:28:50,112 So let's just drop that to something like 100 522 00:28:51,414 --> 00:28:54,620 and then they'll fall a bit more like you would expect. 523 00:28:54,620 --> 00:28:57,625 Leaves to fall 524 00:28:58,259 --> 00:29:00,964 through the air, 525 00:29:00,964 --> 00:29:02,466 which is sweet. 526 00:29:02,466 --> 00:29:04,703 So now we have some cool falling leaves. 527 00:29:04,703 --> 00:29:08,009 Now they just have no rotation or direction to them. 528 00:29:08,009 --> 00:29:11,014 What we really going to want is for them to move 529 00:29:11,715 --> 00:29:13,050 with the wind. 530 00:29:13,050 --> 00:29:14,853 And you can see from the clouds that the means to move 531 00:29:14,853 --> 00:29:17,057 the wind is moving over to the left. 532 00:29:17,057 --> 00:29:19,261 We're going to want them to move over to the left. 533 00:29:19,261 --> 00:29:22,266 So let's add in those things. 534 00:29:22,399 --> 00:29:24,937 I think firstly, let's let's get the wind working first. 535 00:29:24,937 --> 00:29:27,908 So if we just click on Particle up there and just type in wind, 536 00:29:28,977 --> 00:29:31,982 you can add in a wind force. 537 00:29:32,015 --> 00:29:36,022 And let's let's set it to two. Now 538 00:29:39,027 --> 00:29:39,828 what should we do? 539 00:29:39,828 --> 00:29:41,631 What should we do, 100 from here? 540 00:29:41,631 --> 00:29:44,636 Yeah, let's go out there 541 00:29:45,137 --> 00:29:46,940 and then push that. 542 00:29:46,940 --> 00:29:49,945 So right now 543 00:29:50,913 --> 00:29:53,050 try and let's see if you can see anything happening. 544 00:29:53,050 --> 00:29:56,055 You shouldn't be able to. 545 00:29:56,155 --> 00:29:58,493 And that's because wind force is not above. 546 00:29:58,493 --> 00:30:02,032 So forces and velocity, which you need it to be for it to do that. 547 00:30:02,032 --> 00:30:05,037 So you see now they start moving over to the left, 548 00:30:05,504 --> 00:30:08,276 which is exactly what we want, although maybe, 549 00:30:08,276 --> 00:30:11,281 maybe they're moving a little bit to 550 00:30:11,447 --> 00:30:13,351 maybe bring this down. 551 00:30:13,351 --> 00:30:16,356 But it's not happening above the trees. 552 00:30:18,927 --> 00:30:19,461 They do. 553 00:30:19,461 --> 00:30:22,466 So now we have these lovely leaves 554 00:30:22,866 --> 00:30:25,871 falling in one direction, 555 00:30:27,040 --> 00:30:28,609 which is great. 556 00:30:28,609 --> 00:30:29,377 That's what we want. 557 00:30:29,377 --> 00:30:32,883 So we need to make sure that we have wind force above so forces and velocity 558 00:30:33,217 --> 00:30:36,189 so that it solves the forces in velocity and they actually work. 559 00:30:36,690 --> 00:30:41,698 The next thing that we're going to want to do is to just add in some rotation. 560 00:30:43,167 --> 00:30:45,337 So what we want to do for that is just to add 561 00:30:45,337 --> 00:30:48,843 in a solver, rotational forces and velocity, which is kind of like that. 562 00:30:48,843 --> 00:30:50,613 But yeah, 563 00:30:50,613 --> 00:30:52,750 so, so 564 00:30:52,750 --> 00:30:55,755 rotation 565 00:30:56,856 --> 00:31:00,563 and now you'll see all of the rotation stuff 566 00:31:00,563 --> 00:31:04,235 that we added in to add rotational velocity up here is now being solved 567 00:31:05,404 --> 00:31:07,441 and we've got some leaves 568 00:31:07,441 --> 00:31:10,446 spinning around in the wind, 569 00:31:12,750 --> 00:31:15,621 which is great. 570 00:31:15,621 --> 00:31:16,088 That's it. 571 00:31:16,088 --> 00:31:18,693 Pretty much We've, we've kind of nailed it already, right? 572 00:31:18,693 --> 00:31:22,265 We've got these sweet looking leaves floating through the air. 573 00:31:25,738 --> 00:31:28,743 Now the next thing we want to do is add in the other leaf, Right? 574 00:31:28,977 --> 00:31:30,512 So to do that, 575 00:31:30,512 --> 00:31:33,818 we're just going to delete that comment box that I've managed to make. 576 00:31:34,987 --> 00:31:37,958 We're just going to copy this one. 577 00:31:39,995 --> 00:31:40,562 And where 578 00:31:40,562 --> 00:31:44,002 we've got mesh render, we just find the other leaf 579 00:31:45,905 --> 00:31:46,840 that in there 580 00:31:46,840 --> 00:31:49,611 and then because they're bigger, they'll be a little bit heavier. 581 00:31:49,611 --> 00:31:50,946 So let's give them some more gravity. 582 00:31:50,946 --> 00:31:54,052 So let's give that like 300 and they should fall quicker 583 00:31:55,988 --> 00:31:56,890 than the other ones. 584 00:31:56,890 --> 00:31:59,895 And those should have two. Lots 585 00:32:00,128 --> 00:32:03,133 of leaves falling through the sky, 586 00:32:03,768 --> 00:32:06,773 which is great. 587 00:32:08,676 --> 00:32:09,911 Now what you'll notice 588 00:32:09,911 --> 00:32:12,983 we don't have is some collisions. 589 00:32:12,983 --> 00:32:17,925 So these particles at the moment are just kind of falling through the floor and 590 00:32:19,294 --> 00:32:23,634 considering considering their leaves and the rotation that they have and so on 591 00:32:24,135 --> 00:32:25,804 and all these different factors is really 592 00:32:25,804 --> 00:32:28,776 I mean, we're only going to be able to do so much here 593 00:32:29,444 --> 00:32:31,447 without getting too in-depth into this. 594 00:32:31,447 --> 00:32:34,185 So what I'm going to do is let's add in some collision 595 00:32:34,185 --> 00:32:36,756 and then have them so that they come to a gradual stop 596 00:32:36,756 --> 00:32:39,327 and then they'll leave for a few seconds before they disappear and die. 597 00:32:40,796 --> 00:32:43,968 And the way that we do that is by just hitting particles up. 598 00:32:43,968 --> 00:32:46,973 They and then just type in collision 599 00:32:47,407 --> 00:32:51,280 and let's just pull that under wind force 600 00:32:52,749 --> 00:32:55,387 and let's 601 00:32:55,387 --> 00:32:56,288 do some things here. 602 00:32:56,288 --> 00:33:00,195 So what we've what we've done should initially just give us some collision 603 00:33:00,195 --> 00:33:00,562 anyway. 604 00:33:00,562 --> 00:33:03,567 So you'll see that one, they're just rolling along the floor. 605 00:33:03,667 --> 00:33:05,571 I'm trying to find another one. 606 00:33:05,571 --> 00:33:07,874 There you go. There's another one rolling on the floor there. 607 00:33:07,874 --> 00:33:10,879 The large ones are still falling through because we've not had a collision to them. 608 00:33:10,879 --> 00:33:12,916 And there's another one there. So you can see them. 609 00:33:12,916 --> 00:33:15,487 They just continue on along the floor. 610 00:33:15,487 --> 00:33:18,659 So there are a few settings here that we can add in there, some bounce. 611 00:33:18,659 --> 00:33:21,497 So there's like restitution. 612 00:33:21,497 --> 00:33:23,801 If you add in zero, they'll stop initially. 613 00:33:23,801 --> 00:33:25,203 Well, they won't have any bounce at all. 614 00:33:25,203 --> 00:33:27,173 And if they have one, then they'll bounce 615 00:33:27,173 --> 00:33:30,178 with exactly the same amount as force as they hit the ground with. 616 00:33:30,512 --> 00:33:32,081 So let's give them 617 00:33:33,350 --> 00:33:36,288 0.3. They shouldn't be very bouncy. 618 00:33:36,288 --> 00:33:38,826 That leads 2.2, actually. Let's do that. 619 00:33:38,826 --> 00:33:40,095 And then friction. 620 00:33:40,095 --> 00:33:43,768 The friction coefficient defines how quickly a particle will slow down 621 00:33:43,768 --> 00:33:45,637 as it slows across the surface. 622 00:33:45,637 --> 00:33:46,806 So let's just give that one. 623 00:33:46,806 --> 00:33:49,778 Let's make it slow down pretty quickly, 624 00:33:51,948 --> 00:33:53,517 maybe 0.8. 625 00:33:53,517 --> 00:33:55,420 Let's make it slow down very quickly that way. 626 00:33:55,420 --> 00:33:59,227 And then all we do after that is 627 00:34:01,998 --> 00:34:03,968 control roll on collision, 628 00:34:03,968 --> 00:34:08,108 which should stop all of the rotational stuff 629 00:34:08,108 --> 00:34:11,113 that we've got going on when it hits the ground. 630 00:34:11,647 --> 00:34:14,752 So let's turn that on and then let's do that 631 00:34:14,752 --> 00:34:17,757 for I mean, copy and paste over here. 632 00:34:18,559 --> 00:34:21,464 We can be pulled out to force the wind falls 633 00:34:21,464 --> 00:34:24,502 under wind force, and then let's have a look and see how that looks. 634 00:34:26,739 --> 00:34:29,277 See if we can see you hit the ground. 635 00:34:29,277 --> 00:34:32,282 So they hit the ground a bit, spin around and then stop. 636 00:34:32,983 --> 00:34:35,988 So we're getting some leaves falling on the ground here, which is quite nice. 637 00:34:39,527 --> 00:34:40,228 So I think 638 00:34:40,228 --> 00:34:43,534 probably what we're going to want to do just to stop this being a constant 639 00:34:43,534 --> 00:34:46,505 gust of wind is just reduce the amount that is happening. 640 00:34:47,006 --> 00:34:50,011 So if we just make this big again, 641 00:34:50,211 --> 00:34:53,517 go over to emitter update and then change this form, 642 00:34:53,517 --> 00:34:56,522 count down to ten for each, 643 00:34:57,457 --> 00:34:59,293 you should have half the amount of leaves 644 00:34:59,293 --> 00:35:02,298 should feel a little bit more natural. 645 00:35:03,367 --> 00:35:05,437 Perfecto. 646 00:35:05,437 --> 00:35:08,442 So let's save that. 647 00:35:08,509 --> 00:35:10,746 And here we have our falling leaves. 648 00:35:10,746 --> 00:35:13,751 Next what we'll move on to is just doing a similar thing. 649 00:35:14,251 --> 00:35:16,088 The rest of the systems work in a similar way. We're 650 00:35:16,088 --> 00:35:19,861 just going to kind of hijack a system and then make it work for what we want. 651 00:35:19,861 --> 00:35:23,500 But the dust motes and the little sprites work in very similar ways. 652 00:35:23,500 --> 00:35:26,138 Just one we're going to have much more small and contained, 653 00:35:26,138 --> 00:35:28,609 and the other one is going to be a very much larger area, 654 00:35:28,609 --> 00:35:31,213 and then one of them will be a little bit massive and the other one won't. 655 00:35:31,213 --> 00:35:34,218 But those two will be fairly simple. 656 00:35:34,218 --> 00:35:37,056 But yeah, hopefully you've gotten a bit more to grips 657 00:35:37,056 --> 00:35:40,028 with the Niagara system 658 00:35:40,094 --> 00:35:43,567 and I would try some of the other forces as well. 659 00:35:43,567 --> 00:35:44,569 They're really cool 660 00:35:44,569 --> 00:35:48,275 and throw loads of particles in and then play around with the other forces 661 00:35:48,275 --> 00:35:50,078 and see what kind of cool effects you can get. 662 00:35:50,078 --> 00:35:52,882 You can make some really sweet stuff using this system, 663 00:35:52,882 --> 00:35:55,687 but you can see how quickly it was just to make falling leaves, which is nice.
