WEBVTT 00:00.210 --> 00:05.280 Now that our cash is done, let's take a look at it, but before we start scrubbing through the timeline, 00:05.280 --> 00:09.030 we want to remember that we want to change cash control back to one. 00:09.540 --> 00:14.900 And that means it will read the cash files from this location that we've set. 00:15.360 --> 00:17.040 So let's change this back to one. 00:17.040 --> 00:20.190 And now we can scrub and see the cash. 00:20.730 --> 00:28.590 So there's one little thing that ended up happening when I copy paste in the frames for the ATM, the 00:29.610 --> 00:38.340 the if we take a look at the graph editor here, we can see that in this section it actually goes scale's 00:38.340 --> 00:42.090 into the negative, which I didn't intend for it to do. 00:42.090 --> 00:44.700 I meant for it to be a flat tangent handle. 00:44.700 --> 00:48.120 So it'll be flat like this, but it was set to spline. 00:48.360 --> 00:53.610 And so in this middle section, it actually goes to zero and then comes back out. 00:53.880 --> 01:01.980 So it has a little bit of a whisper of smoke here, which maybe is kind of cool. 01:01.980 --> 01:08.310 But because also we set the dissipation to be higher, we can see the smoke kind of dissipates pretty 01:08.310 --> 01:08.880 quickly. 01:09.150 --> 01:11.180 It rises up and then it goes away. 01:11.190 --> 01:18.630 And that also helps us because you can see as the simulation continues to go and run, this bounding 01:18.630 --> 01:23.820 box gets bigger and bigger because the voxel area, which the smoke is covering, is getting bigger 01:23.820 --> 01:24.300 and bigger. 01:24.750 --> 01:31.560 And the longer we let that smoke rise, the bigger and larger of an area that it has to calculate. 01:31.860 --> 01:40.410 So when we set the dissipation high and the smoke disappears, we can help kind of limit that kind of 01:40.860 --> 01:47.150 very computationally expensive expansion to be smaller. 01:47.160 --> 01:49.580 So see how the box now reduces back down. 01:50.040 --> 01:54.270 So we never really get to a huge size because the smoke dissipates before that happens. 01:54.900 --> 02:00.300 And we were controlling that through the dissipation here under the properties. 02:00.660 --> 02:03.420 And we were down here on the air. 02:03.750 --> 02:07.530 And we want smoke dissipation and we increase that to 10 from one. 02:07.980 --> 02:09.870 So that helped us with that. 02:10.170 --> 02:14.790 And then we had this little trail smoke here because the emitter was scaled into the negative because 02:14.790 --> 02:15.840 of the tangent handles. 02:16.140 --> 02:21.030 And now we can see the smoke from him popping out. 02:21.360 --> 02:27.630 And you can see where the collider actually worked really well, that it drug this smoke out with it. 02:28.500 --> 02:35.940 So we can see as he passes through the smoke, it kind of collects around the vest a little bit and 02:35.940 --> 02:41.490 then it gets dragged and pulled with his motion, which is really nice, is going to help direct the 02:41.490 --> 02:44.640 eye through this fast animation. 02:44.850 --> 02:49.110 It's going to kind of help to have that motion of the smoke be centered around him. 02:49.860 --> 02:56.490 And so at this stage of the game, we have a pretty good simulation working. 02:56.670 --> 03:03.180 The last thing I want to take a take a look at is in the rendering of this. 03:03.420 --> 03:07.890 So I'm just going to create a directional light just so we have some type of light in the scene. 03:08.130 --> 03:13.470 So I'm just going to create a directional light and I'm a scale that up and I want to show lights so 03:13.470 --> 03:18.150 that we can see that and the direction it's going in, it's going to kind of go at a three quarter angle 03:18.160 --> 03:18.900 downward. 03:19.320 --> 03:30.030 And now let's go into the Bifrost container here and we can go to the mesh and that way we can get over 03:30.030 --> 03:31.320 to the arrow material. 03:31.680 --> 03:32.610 So we click on that. 03:32.610 --> 03:35.610 We can see the volume material is in a standard volume. 03:35.910 --> 03:38.550 We click this little arrow, we get into the material itself. 03:38.970 --> 03:46.740 So let's turn on the Arnold reinterview here and just see what we have right out of the box so we can 03:46.740 --> 03:48.180 see it's it's dark. 03:48.180 --> 03:53.850 It's basically black and but it's looking pretty good. 03:54.780 --> 03:57.090 It's a little it doesn't have a ton of texture to it. 03:57.090 --> 04:03.390 And again, that's because our resolution is still fairly low, but it's looking pretty good. 04:03.390 --> 04:06.630 But to make this a little more readable, I want to change the color of this. 04:06.900 --> 04:13.110 So in the scatter spot over here, I'm just going to increase that color to be a little more white. 04:13.360 --> 04:14.820 We can also give it a color. 04:14.820 --> 04:16.920 We could give it like a purple color or something like that. 04:18.510 --> 04:21.990 But yeah, that's in general how that works. 04:22.410 --> 04:28.260 We could also increase the kind of emission instead of temperature. 04:29.220 --> 04:30.660 We could change that to density. 04:30.660 --> 04:37.380 So basically the emission of this color is dependent on the temperature. 04:37.830 --> 04:45.660 And so we don't really have we can change the channel so that that should change it. 04:46.050 --> 04:50.340 As we do this, you can see it really changes the look. 04:50.340 --> 04:56.430 So this is more for something like fire or something like that, because temperature obviously is more 04:56.430 --> 04:58.530 related to fire type of things. 04:58.920 --> 04:59.940 So we could change the color of. 04:59.990 --> 05:07.100 That we could also change this to density so that the density of the smoke is what affects the color 05:07.400 --> 05:11.530 in this channel, but it's pretty sensitive, as you can tell. 05:11.870 --> 05:13.700 So I don't really use that one that much. 05:14.000 --> 05:17.030 But basically, it's going to be between density here. 05:17.300 --> 05:18.320 We can increase it. 05:18.320 --> 05:23.540 So it's like very, very smoky, thick smoke or we could just reduce it down. 05:23.550 --> 05:28.440 So it's just barely even there, kind of like a magical smoke. 05:29.780 --> 05:33.260 So that's pretty much it for the smoke. 05:33.560 --> 05:39.980 And feel free to mess around with all of these different attributes to get a type of look that you're 05:39.980 --> 05:43.780 interested in and yeah, keep playing around with it. 05:44.000 --> 05:45.710 And again, you know, we can change. 05:45.710 --> 05:47.390 We can go values past what's here. 05:47.390 --> 05:48.680 This value is on one. 05:49.040 --> 05:55.350 But, you know, I can just crank that up so that it's, you know, a value that I want. 05:55.370 --> 05:56.630 So it's a little bit brighter. 05:57.540 --> 05:59.060 We could also keep going with that. 05:59.300 --> 06:02.240 You can see it changes the edge of this stuff, too. 06:02.510 --> 06:04.760 So because this is based on 06:08.060 --> 06:16.080 just kind of the density of the smoke, these values will change quite a bit, the transparency of it. 06:16.460 --> 06:22.880 So anyway, just play around with the material a little bit and we're going to light this again later 06:22.880 --> 06:23.630 on in the course. 06:23.630 --> 06:28.910 But just wanted to show you how to change basic stuff like color and. 06:28.910 --> 06:35.300 Yeah, and the next lesson, we will continue on and finish up work on finishing up the scene. 06:35.720 --> 06:36.710 So thanks for watching.
