WEBVTT 00:00.390 --> 00:06.300 In this lesson, we're going to do some pretty fun and learn about fog and lighting, so at this stage 00:06.300 --> 00:11.560 of the game, you should have a pretty well textured and shaded Ghostbuster trap. 00:11.580 --> 00:13.750 Let's just take a look at what we have so far. 00:14.160 --> 00:21.810 I have done some three texturing on the other shaders and basically put in a mix shader for everything 00:21.810 --> 00:26.370 so that we can map in a chrome texture underneath. 00:26.610 --> 00:28.680 So it looks like this stuff is kind of painted. 00:28.950 --> 00:33.210 And then the scratches reveal more of a metal chrome texture on this stuff. 00:33.510 --> 00:35.430 So it's all the same techniques. 00:35.430 --> 00:37.590 You've learned how to add rust to these plates. 00:37.920 --> 00:44.300 And in this way it's using the textures to reveal chrome. 00:44.310 --> 00:48.810 So it looks like painted metal and with some scratches on it. 00:48.810 --> 00:52.810 So it adds a lot more realism and kind of organic quality to it. 00:53.220 --> 00:56.040 So at this stage of the game, this is kind of what we're working with. 00:56.340 --> 01:03.030 Let's make something super cool and have some glowing light and fog coming out of the doors here. 01:03.330 --> 01:05.400 So let's close this down and learn how to do that. 01:05.910 --> 01:07.200 First, let's open up the doors. 01:07.200 --> 01:10.230 We'll just select the geometry at E to rotate this stuff up. 01:10.500 --> 01:15.570 So we need to open the doors up and then let's go into the render settings. 01:15.580 --> 01:17.210 This is something that we haven't touched yet. 01:17.550 --> 01:20.970 It's this little button up here with a clapperboard and the gear wheel. 01:22.430 --> 01:27.770 We like that we get a new window and we want to make sure that we change our render that we're using 01:27.770 --> 01:28.890 to Arnold render. 01:29.150 --> 01:33.770 And again, if you don't have that loaded up, you can just go to Windows settings and preferences, 01:33.770 --> 01:34.640 plug in manager. 01:35.000 --> 01:41.000 And it's down at the MTA, a bundle down here, right here. 01:41.750 --> 01:45.590 So you probably already have that turned on because we've been using Arnold shaders. 01:45.920 --> 01:47.540 But in this case, we need to tell it. 01:47.540 --> 01:49.700 We want to render with this on as well. 01:49.700 --> 01:54.250 And you can see these tabs change and now we get the Arnold Renderer tab. 01:54.500 --> 02:00.680 Let's go down to the environment and now we see atmosphere and we can add a texture into here. 02:00.680 --> 02:05.080 So if we click that, we get some unique options and we're going to want the atmosphere volume. 02:05.090 --> 02:05.930 So let's click that. 02:06.500 --> 02:13.640 And now you can see it's piped in here and we can get to it through clicking this button and you can 02:13.640 --> 02:15.090 see the attributes of it over here. 02:15.410 --> 02:20.120 So before the fog can work, we need some lights to work with it and atmosphere fog. 02:20.120 --> 02:24.470 And Arnold is particular to certain types of lights. 02:24.800 --> 02:31.310 It will not work with infinity based lights, meaning sky domes and directional lights that come from 02:31.310 --> 02:33.200 an infinite distance. 02:33.440 --> 02:35.540 So it really like spotlights. 02:35.540 --> 02:37.490 So we're going to add a spotlight to the scene. 02:37.490 --> 02:38.870 So let's close the render settings. 02:39.110 --> 02:46.430 And you notice under Arnold lights, it does not have a spotlight, but it is actually located over 02:46.430 --> 02:49.820 here with this little flashlight and it'll still work in Arnold. 02:49.820 --> 02:53.050 It's just not an Arnold only light like those other ones are. 02:53.450 --> 03:00.110 So let's click the spotlight and you can see we've created it here and we need to enable show lights 03:00.470 --> 03:04.460 under this tab if we've turned it off like we did earlier in the series. 03:04.940 --> 03:11.000 So now we can manipulate this like anything else, rotate it up and shoot it in the direction of straight 03:11.000 --> 03:12.020 up as what we want. 03:12.950 --> 03:14.450 Let's kind of set this in here. 03:14.870 --> 03:18.920 And as long as we don't have this point at the bottom, go through the geometry. 03:19.430 --> 03:21.350 You know, this is too far right there. 03:21.350 --> 03:30.050 We want to get it just above the kind of floor of this bottom and let's rotate that and even direction. 03:30.050 --> 03:30.680 So. 03:30.680 --> 03:34.610 Ninety degrees and now let's see what we have. 03:34.610 --> 03:35.990 Let's turn on the Arnold render view. 03:37.980 --> 03:41.260 And hit play and nothing really happens. 03:41.670 --> 03:46.200 So why is that if we go into the atmosphere fog, we can get to it back through the winter settings. 03:47.730 --> 03:53.190 And click this little button now and go to the street editor, kind of we can see it kind of almost 03:53.190 --> 03:55.380 like a Qader, like we had been shading things. 03:55.770 --> 03:58.500 And you can see what's going on in this sub. 03:58.500 --> 04:02.220 So you can see the density is automatically set to zero, which is not very helpful. 04:02.220 --> 04:07.050 If you're creating this, you would assume that the default would be at some value greater than zero. 04:07.350 --> 04:10.210 But yeah, sometimes the defaults aren't what you want them to be. 04:10.500 --> 04:16.950 So if we increase this, we should start to see some fog and you'd see it start to illuminate right 04:16.950 --> 04:17.310 here. 04:20.380 --> 04:22.060 So now you can kind of see it illuminate. 04:22.090 --> 04:24.740 Let's turn this all the way up and now we can get some fog. 04:24.760 --> 04:25.350 Check that out. 04:26.350 --> 04:28.750 And it's basically taking the shape of the light. 04:29.080 --> 04:30.990 So we need to adjust the light. 04:31.000 --> 04:32.740 So that is a little bit broader. 04:32.740 --> 04:34.870 So it fills up this entire piece here. 04:35.200 --> 04:37.120 Or you can just leave it like this if you like. 04:37.480 --> 04:41.170 But I'm going to make mine a little bigger and there's a couple of different tools we can use for the 04:41.170 --> 04:41.740 spotlight. 04:42.070 --> 04:43.240 So I'm going to click the spotlight. 04:44.360 --> 04:45.050 And. 04:46.280 --> 04:52.220 I'm going to increase the intensity so you can see the fog almost feels like it's more intense fog by 04:52.220 --> 04:56.960 increasing the intensity of the light itself and we can increase the cone angle. 04:57.270 --> 04:58.490 So let's just spread that out. 05:00.860 --> 05:08.060 And let's also increase the penumbra angle, and that's basically like the feathering of this, as you 05:08.060 --> 05:10.770 can see how hard this edges of the spotlight. 05:11.180 --> 05:14.480 Now watch it as we increase the penumbra angle, it gets a lot softer now. 05:14.480 --> 05:15.890 You can't see that hard edge. 05:16.160 --> 05:19.100 So it's super helpful, maybe went a little too far. 05:19.100 --> 05:20.750 So we can just dial it back a little bit. 05:22.190 --> 05:26.570 Now, let's go take a look at the fog because it's just white and that's fine. 05:27.140 --> 05:29.660 But I think it can be look a lot more interesting. 05:29.660 --> 05:30.980 And I'm just going to move this over. 05:30.980 --> 05:32.090 Just a touch. 05:34.270 --> 05:39.490 Trying to keep both of these things in the scene scenes, you can see it update as well, so I'm just 05:39.490 --> 05:44.320 moving it over so that the light is kind of emitting from the middle of the doors and not from one end 05:44.320 --> 05:44.780 or the other. 05:45.850 --> 05:47.790 So now we have that. 05:47.800 --> 05:50.650 Let's go back into the atmosphere and mess with that. 05:51.380 --> 05:54.160 So the density is that a value of one? 05:54.160 --> 05:56.770 We could mess with that a little more. 05:57.850 --> 06:03.550 The other thing I want to do is make this a purple color because it is a, you know, ghost alien type 06:03.550 --> 06:04.350 of a trap. 06:04.450 --> 06:09.070 We want some more interesting color than just white so you can change the color here. 06:09.310 --> 06:14.800 And then finally, the thing that's really going to make this look amazing is by adding a texture to 06:14.800 --> 06:15.370 the density. 06:15.640 --> 06:17.530 You can see that we have this checkbox over here. 06:17.530 --> 06:21.040 So you guessed it, just like everything else, we can type in a texture here. 06:21.340 --> 06:22.410 So let's click that. 06:22.420 --> 06:28.660 And the only thing special we need to consider about this is the fact that this fog is kind of 3D, 06:28.660 --> 06:29.050 right? 06:29.860 --> 06:33.970 It is taking up space in three dimensions. 06:34.190 --> 06:36.000 It's not just on a flat plane. 06:36.220 --> 06:41.080 So when we look at what type of texture we want to map in here, we need to look at 3D textures. 06:41.410 --> 06:43.060 And 3D textures are just that. 06:43.060 --> 06:49.600 They're basically a texture that goes through a volume, you know, imagine like putting, I don't know, 06:49.780 --> 06:52.750 glitter or ink or something in a glass of water. 06:52.990 --> 06:55.120 It's going to create patterns in three dimensions. 06:55.420 --> 06:57.870 And that's kind of the same idea that we want to do here. 06:58.120 --> 07:01.480 So I'm going to create a cloud texture here. 07:01.760 --> 07:07.390 As soon as I click that, you can see it adds all this great organic texture to the fog and it looks 07:07.390 --> 07:11.080 so much more believable than the solid piece that we had. 07:11.350 --> 07:18.880 And of course, we can adjust the attributes of this cloud as well and increase that or decrease that. 07:19.420 --> 07:27.580 But yeah, so this is pretty much how you create some cool looking fog coming out of your Ghostbuster 07:27.580 --> 07:27.960 trap. 07:28.210 --> 07:32.620 So I'm going to just tweak this stuff a little bit for one second. 07:32.890 --> 07:38.140 You can stop now or you can kind of go along with me and see how I'm going to finish this out. 07:38.980 --> 07:41.800 You know, it's all about that kind of final 10 percent. 07:42.160 --> 07:47.110 And I like to get let's get that highlight on this three core angle so we can kind of see the highlight 07:47.110 --> 07:47.710 of this. 07:48.550 --> 07:55.630 And let's also increase the intensity of the spotlight so that it's a bit of a stronger effect. 07:55.630 --> 08:00.220 And, of course, we can type in a bigger number here to something like twenty and see what happens. 08:00.700 --> 08:01.780 It looks a lot better. 08:02.200 --> 08:06.130 And yeah, that's already looking really, really good. 08:07.690 --> 08:15.070 I love how quickly and simply you can add so much more in Maya and with Arnold's toolset. 08:15.550 --> 08:19.750 So that is how you add fog to the Ghostbuster trap. 08:20.230 --> 08:24.820 And of course you can animate all this stuff that we'll learn how to animate later on in another section. 08:25.150 --> 08:32.170 But yeah, that's that's a really useful look Dev tool to add a lot of dimensionality and atmosphere 08:32.170 --> 08:37.030 to all of your renders as you finish them up and put the final polish on them. 08:37.240 --> 08:43.210 So in the next few lessons, we're going to go back to the Bones character model and kind of finish 08:43.210 --> 08:44.050 that one up as well. 08:44.050 --> 08:48.190 I'm going to show you a few more tips and tricks and then we're going to finish this whole section out 08:48.190 --> 08:53.440 with a covering how we're actually going to render a sequence or final image out of Arnold and Maria. 08:53.710 --> 08:55.600 So thanks for watching and I'll see you in the next lesson.
