WEBVTT 00:00.420 --> 00:05.370 And this lesson, we're going to finish up creating the Firefly's and create a couple more fields to 00:05.370 --> 00:10.320 animate so that they will scurry away when the grave explodes. 00:10.860 --> 00:14.850 So there's one of their little visibility thing I forgot to mention in the last lesson when I was talking 00:14.850 --> 00:16.620 about how slow everything was going. 00:16.950 --> 00:24.240 We can actually limit the particles being populated by only what this camera sees. 00:24.660 --> 00:28.560 And that's a something specific to MASH and the visibility node. 00:28.930 --> 00:35.820 So let me crank up the distribution that we have back to what we, you know, originally had here to 00:35.820 --> 00:37.440 make it look a little more full. 00:38.040 --> 00:42.490 And you can see everything is kind of getting a lot slower. 00:42.540 --> 00:47.130 So what we can do let's go back to frame first frame here. 00:52.940 --> 00:57.920 And I'm going to lower this down a little bit because it looks like it was shooting everything up, 00:57.920 --> 01:02.930 maybe too much, and I'm just going to maybe reduce this down as well. 01:03.680 --> 01:06.650 Twenty five hundred or what was that half yet? 01:06.680 --> 01:09.440 Twenty five hundred and then. 01:09.890 --> 01:10.160 Yeah. 01:10.170 --> 01:17.150 So for this visibility thing, if we go to the visibility node and the Masche set up here, we go down 01:17.150 --> 01:19.730 to a fresh tom filtering. 01:20.090 --> 01:27.290 And if we enable that, we just need to connect a camera and it will limit which particles are drawn 01:27.290 --> 01:28.450 based on that camera. 01:28.850 --> 01:35.420 So it's middle mouse drag the render cam into this camera slot and let go and then watch this and it 01:35.420 --> 01:39.480 should update and get rid of a lot of these particles that we can't see. 01:39.530 --> 01:40.400 So check that out. 01:41.660 --> 01:42.240 It's pretty cool. 01:42.740 --> 01:45.350 So it should speed everything up quite a bit now. 01:45.740 --> 01:49.730 And we can leave things at the kind of settings that we wanted. 01:50.270 --> 01:56.540 7C We're starting to get some Firefly motion here and. 01:57.530 --> 01:58.440 It's looking OK. 01:58.550 --> 02:02.480 I want to increase the frequency of this first. 02:04.950 --> 02:12.930 Turbulent field, so let's just crank that up and because I want a little more higher frequency here, 02:13.500 --> 02:17.550 because I want to I want to see them change direction more frequently. 02:18.120 --> 02:23.880 So I'm just going to continue to play with this frequency and let's just crank that all the way up to 02:23.880 --> 02:24.450 100. 02:31.570 --> 02:36.960 And part of dynamics work in dynamics as things get a little slow, as everything is trying to update, 02:37.450 --> 02:43.110 so especially when you're starting to work with, you know, these MASH dynamics and this many particles. 02:44.770 --> 02:49.700 So it looks like things are moving a little quicker. 02:49.720 --> 02:51.640 Let me escape. 02:51.640 --> 02:56.410 And the one thing I'm seeing is that this uniform field is maybe still way too much. 02:56.980 --> 03:04.630 So I'm just going to knock a zero off of that and add spacebar here and go to dynamics and let's just 03:04.630 --> 03:06.070 crank way up. 03:06.580 --> 03:11.620 That's going to turn the field and crank up the frequency to like 300 and see what happens. 03:33.500 --> 03:41.050 So I'm just going to escape out of this and I am actually going to also reduce the number here, you 03:41.050 --> 03:43.140 know, we're using the restroom thing. 03:43.360 --> 03:46.210 It's still just so much that it's it's going so slow. 03:46.210 --> 03:51.310 It's hard to tell what actually is happening with turbulence field. 03:51.790 --> 03:57.070 So I'm just going to crank those way down and then go back to turbulence field. 03:57.070 --> 04:00.100 And I think this is maybe acting on it too much. 04:00.490 --> 04:05.150 I think we need more frequency and less motion. 04:05.170 --> 04:12.190 Basically, what I'm getting at is what you can stack on multiple fields so we could have multiple turbulence 04:12.190 --> 04:12.750 fields. 04:12.770 --> 04:13.810 Yeah, it's way too slow. 04:14.350 --> 04:23.200 We could have multiple turbulence fields and on top of each other that have different magnitudes. 04:23.200 --> 04:30.680 So we could have like a really high frequency one and then a really low frequency one and another and 04:30.700 --> 04:33.340 escape on that and then go back to frame one. 04:33.940 --> 04:39.250 And let me just make sure sometimes on the bullet over the start frame, if you reopen a scene, it 04:39.250 --> 04:40.510 might not save that star frame. 04:40.520 --> 04:41.790 So always check that as well. 04:42.220 --> 04:47.380 So we have the turbines field adjusted now to 15000. 04:48.680 --> 04:50.360 And a really high frequency. 04:56.040 --> 04:58.380 So it looks like things are moving, but it's still. 05:02.380 --> 05:05.920 Still pretty slow, some cranking up the magnitude again. 05:13.130 --> 05:15.510 I think I need to add a zero on this frequency. 05:15.530 --> 05:19.400 Let's add a zero to this frequency and see where that gets us. 05:37.310 --> 05:43.370 Yeah, so I'm happy with that and we could do a bigger turbulence field if we wanted to, but I think 05:43.850 --> 05:47.180 really this is enough, we could just keep stacking on turbulence fields. 05:47.180 --> 05:56.500 But I do want to add one for the kind of moment when the gravy breaks. 05:56.510 --> 05:59.810 So let's crank this way up. 05:59.810 --> 06:02.120 Let's look at the first one and do like double that. 06:02.120 --> 06:05.870 So that's 25000 and 6000. 06:05.880 --> 06:11.690 So let's do like 50000 and. 06:13.040 --> 06:21.500 12000, and then we just need to attach this again to the bullet solver, so let's go to there and middle 06:21.500 --> 06:24.350 mouse trying to the this field in and play. 06:32.380 --> 06:39.880 I think we could maybe even use another zero here, this term loans field is going to be animated on 06:39.880 --> 06:47.280 so we can use the max distance or, you know, we could use a volume as well. 06:47.650 --> 06:55.570 So I'm just going to crank this up maybe to a eighty thousand and see if that really makes things erratic. 06:55.900 --> 07:00.070 Because basically what I want to see is these things really starting to move. 07:01.870 --> 07:03.640 Yeah, I think we could go even higher. 07:05.920 --> 07:08.590 So we're at 100000, I believe. 07:22.590 --> 07:24.120 It's too like one 150. 07:32.120 --> 07:38.720 Yeah, now these are really starting to move, so I think I think 150 will do us is pretty well. 07:40.880 --> 07:51.620 And so then I want to create a credit as a volume and let's have something like a sphere and I'll go 07:51.620 --> 07:54.940 back to the perspective mode and scale this guy up. 07:59.010 --> 08:04.140 And I'm going to introduce it when the animation kind of first happens with the first. 08:06.450 --> 08:07.830 Which is kind of early on. 08:09.570 --> 08:12.390 And we can just animate this on just like everything else. 08:12.420 --> 08:18.360 So let's figure out there is kind of where we want it to. 08:18.540 --> 08:19.440 Come on. 08:31.500 --> 08:33.390 And I'll just drag this down. 08:39.520 --> 08:46.300 So it will kind of introduced into this area and then let's go forward. 08:53.160 --> 09:00.960 And then when we zoom out right before that happens, I want them to really scatter, so I'm just going 09:00.960 --> 09:05.820 to scale it up one, two, three and. 09:06.800 --> 09:09.080 Let's maybe do like six frames. 09:10.680 --> 09:12.860 And I kind of wanted to cover the whole area here. 09:18.580 --> 09:23.620 And then the other thing I want to do, let's just make sure this is working first, but then I'm going 09:23.620 --> 09:27.070 to add a radio field so that everything just kind of. 09:29.830 --> 09:36.820 You know, it goes way, way out, just shoots out with a radio field and away from this grave. 09:38.090 --> 09:42.920 So right now, everything is pretty calm, I don't even know if we have a particle in there that we 09:42.920 --> 09:50.210 can really see this is happening, some might want to increase the distribution again to 20. 09:53.660 --> 09:58.940 So now let's play it back with that turbulence field and these particles kind of increased here. 10:00.440 --> 10:01.910 And let's see what we can get. 10:11.520 --> 10:16.920 So it looks like it's spread them up enough that they get NALGO outside of that field, which is pretty 10:16.920 --> 10:17.230 good. 10:17.250 --> 10:22.530 And so the next thing I want to do is add the radial field. 10:22.530 --> 10:29.910 So I'll go to radio and then let's go to the board, salver and millennialist drag in the radio field. 10:33.100 --> 10:38.710 And then let's go to the radio field, we can just double click it here to get to it and let's use max 10:38.710 --> 10:47.530 distance and it's already kind of where we need it to be so we can just leave it here and then max distance, 10:47.530 --> 10:48.850 we just want to animate that. 10:52.030 --> 10:57.010 So let's go to the frame where he really starts to bust out of this thing. 11:09.450 --> 11:14.610 So it started right in here, I'm al Qaeda and then let's go. 11:15.970 --> 11:22.570 Kind of in here and let's just increase this distance to. 11:24.850 --> 11:28.120 Let's say five hundred or so. 11:32.490 --> 11:41.580 So now the plane is back, we should have all of these kind of fireflies scurrying away when the grave 11:41.580 --> 11:42.410 busts open. 11:43.290 --> 11:49.180 So for us to see that a little better, I'm going to show turn off the everything basically and just 11:49.180 --> 11:55.140 say show polygons and show the GPU cash. 11:57.400 --> 12:02.110 So that we can see this better, I'm actually just going to play blast this, so before I do that, 12:02.110 --> 12:08.230 I want to turn off everything under show and only turn on polygons and the particle and sensors. 12:08.680 --> 12:11.020 And then I'm going to start a play blast by. 12:11.020 --> 12:11.230 Right. 12:11.230 --> 12:16.090 Clicking going to the play blast options here and all that looks fine. 12:16.360 --> 12:19.900 And I might just want to turn off the film gate here so it won't include that. 12:20.290 --> 12:22.720 And I'll hit play Blast and I'll see you in one second. 12:34.780 --> 12:40.300 Now we're back and we can kind of see what we've accomplished here in real time, it looks like we have 12:40.300 --> 12:46.030 some OK motion happening here and everything kind of disperses. 12:46.430 --> 12:48.550 I think everything could happen a lot quicker. 12:48.970 --> 12:50.980 Like all these are moving pretty slow. 12:52.690 --> 12:55.240 So I think we just crank up the magnitude on everything. 12:56.800 --> 13:02.650 And these are moving not ideally either. 13:04.870 --> 13:09.610 So you can tell a lot of this is just kind of playing with the attributes of. 13:13.160 --> 13:19.070 Yeah, I think we just really need to crank up the radio and then also maybe add. 13:23.170 --> 13:24.820 A little more frequency. 13:25.900 --> 13:32.380 And magnitude to the first turbulence, so we just get a little more emotional, these guys, so let's 13:32.380 --> 13:39.400 take a look at that again real quick and let's just increase the magnitude on the radio field. 13:40.390 --> 13:42.370 So this really needs to. 13:43.850 --> 13:50.630 Oh, this is this is what the problem was, we never increased the magnitude on this, that would be 13:50.630 --> 13:51.040 it. 13:51.080 --> 13:52.550 That's that's what's going on. 13:53.090 --> 13:54.740 That's why everything is moving so slowly. 13:54.980 --> 13:59.300 I was wondering, we animated the max distance, but we didn't increase the magnitude. 13:59.810 --> 14:09.380 So let's also just grab this first one and let's increase that 6000 insinuation. 14:09.860 --> 14:13.580 And just for fun. 14:14.980 --> 14:24.310 I'm going to add another turbulent field and I'm going to yeah, again, I don't eat anything selected 14:24.310 --> 14:30.430 to add one, and then I need to minimize drag it to the field here. 14:31.030 --> 14:38.230 And what this one's going to be for me is going to be the same similar values, maybe even more like 14:38.230 --> 14:39.520 50000. 14:40.170 --> 14:49.960 But the fact is that 50000, the frequency is going to be very low. 14:50.750 --> 14:54.000 So that's going to do is move these around a larger area. 14:54.520 --> 14:57.640 And so we'll have like small motion from the first turbulence field. 14:58.240 --> 15:03.430 The second one is going to be animated and then the third one is going to just make sure has big sweep 15:03.430 --> 15:04.000 motion. 15:04.360 --> 15:10.450 So I'm going to play blast this again with more radial field magnitude and more magnitude on both of 15:10.450 --> 15:10.900 these. 15:11.230 --> 15:13.930 And I will see you once that's done. 15:27.230 --> 15:32.150 Now, let's take a look at this updated playlist together, and we definitely have a lot more motion, 15:32.570 --> 15:33.680 which is kind of nice. 15:34.160 --> 15:38.060 And yeah, all of those fireflies go away pretty quickly. 15:40.650 --> 15:44.810 Might even slow down the motion a little bit on these. 15:47.190 --> 15:54.240 But it has really nice, erratic look to it, if you if you look here in the left before the camera 15:54.240 --> 16:00.150 motion really starts, you can kind of see they have their own life and they feel alive and they're 16:00.150 --> 16:04.830 all kind of doing their own thing, actually, kind of like the speed they're they're running at right 16:04.830 --> 16:05.250 now. 16:09.360 --> 16:15.000 Almost just wish they were denser around the grave, so I might change the speed on them to get more 16:15.000 --> 16:20.360 around the grave, and then other than that, I think it's looking pretty good. 16:20.370 --> 16:26.910 And I'm going to decrease the scale here so that the you know, here's the last couple of things I'm 16:26.910 --> 16:31.140 going to do when I decrease the scale on the original one. 16:32.700 --> 16:34.440 So they're all kind of smaller. 16:34.800 --> 16:43.110 And then I'm going to animate the visibility step here as this kind of happens. 16:44.670 --> 16:49.950 So they're all kind of kind of flicker out as they get further away, someone had a keyframe here on 16:49.950 --> 16:56.340 random strength and then I'll just go forward a little bit and then just dial that out to zero or her 16:56.340 --> 16:57.570 pretty close to zero. 16:58.860 --> 17:02.140 So if I select that, then I can actually see the key frames here. 17:02.640 --> 17:03.930 So now we have that. 17:03.930 --> 17:08.850 We've reduced the scale of that of this. 17:09.520 --> 17:11.270 Let's go back to the first frame. 17:11.280 --> 17:13.980 It's not updating because it's simulation now, so. 17:15.430 --> 17:20.650 We actually had a simulated every time, maybe I'm just going to increase the distribution a little 17:20.650 --> 17:25.390 bit, just get a few more in here, I think we were at 25 and 25 when we first started. 17:38.250 --> 17:43.050 Yeah, that's looking a lot better and let's just change the seat a little bit to see if we can't get 17:43.050 --> 17:46.370 more concentrated around the grave area. 17:47.310 --> 17:50.820 So now that we have this in a pretty good place, let's cash it out like we've done everything else. 17:51.150 --> 17:56.270 And before we do that, we need to switch over this mesh network into the mesh type. 17:56.700 --> 18:06.990 So let's let's also just reduce the random scale here a little bit and the scale of the base firefly. 18:25.470 --> 18:25.780 Cool. 18:25.800 --> 18:31.680 Yeah, so I just want to make it look like it's kind of a hint of activity going on and not so big that 18:31.680 --> 18:38.010 we can really tell what these things are, actually. 18:38.460 --> 18:41.280 So they're just going to kind of be these glowing shapes. 18:41.850 --> 18:50.070 So I'm going to select the MASH network and go to MASH utilities and say switch mash geometry type. 18:51.460 --> 18:58.180 So now we have a MASH repro mash and we can cache that with the same Alembic cache we've done before, 18:58.180 --> 19:05.530 not for bullet that was had its own, but we can export this as a selection to match to Alembic. 19:05.920 --> 19:11.830 So I'm going to call this 10 Firefly's one. 19:12.340 --> 19:20.200 And we have the whole range and we are going to go back to the normal file format here and we will export 19:20.200 --> 19:20.830 the selection. 19:35.370 --> 19:42.390 So now that we have a repro mesh cashed out, we can actually just turn off this mesh network and we 19:42.390 --> 19:47.550 can go to Cash Alembic, import Alembic and import the Firefly's. 19:47.970 --> 19:50.280 And it looks like it's quite a bit. 19:50.500 --> 19:52.230 That's two hundred and five megabytes. 19:52.770 --> 19:59.790 So, yeah, we we might want to wait until the very end to add those, but yeah, here they are, they 19:59.790 --> 20:01.440 are the Olympic cash. 20:04.300 --> 20:10.810 And now we can kind of scrub playback without having to simulate them on every frame, and I'm just 20:10.810 --> 20:17.380 going to add that surface shader material that we've already chosen from before it's down here, I'll 20:17.410 --> 20:21.300 frame a little bit so we can actually see those fireflies a little bit better. 20:21.730 --> 20:23.170 And yeah. 20:23.170 --> 20:30.470 So in the next lesson, we are going to start looking at the Closs simulation for Bones. 20:30.520 --> 20:31.240 Thanks for watching.
