WEBVTT 00:00.150 --> 00:06.090 Now that we have our oves done, we're going to take a look at shading, texturing and lighting and 00:06.120 --> 00:11.640 we're going to kind of jump back and forth between all of these because they're all related in some 00:11.640 --> 00:12.950 way, shape or fashion. 00:13.260 --> 00:15.170 So in this lesson, let's take a look at shading. 00:15.180 --> 00:16.940 I have the Ghostbuster trap here. 00:17.280 --> 00:23.880 And as always, if we take a look at the reference, we can see that the materials it's made of are 00:23.910 --> 00:24.480 metal. 00:24.820 --> 00:26.820 It looks like there's a painted black metal. 00:27.150 --> 00:33.390 And then there's this kind of maybe brushed metal that has these streaky reflections in it. 00:33.810 --> 00:36.180 And then there's maybe stickers or something on the top. 00:36.600 --> 00:42.020 But pretty much it's a metal material all the way around for the most part. 00:42.060 --> 00:46.450 So let's take a look how we can create a basic metal shader inside Maya. 00:47.400 --> 00:52.230 So if we select this object, we can create a new material by right. 00:52.230 --> 00:55.440 Clicking and going down to assign new material. 00:55.830 --> 01:02.130 But before we get started, I also want to explain how to begin to think about this stuff, because 01:02.400 --> 01:06.600 it's one thing just to show you the buttons to press, but it's another thing to understand the reason 01:06.600 --> 01:07.340 behind this. 01:07.680 --> 01:13.590 So when we start thinking about shading, we need to consider the physical properties of material. 01:13.590 --> 01:19.380 We need to start thinking like material scientists and a physicist, how light interacts with surfaces 01:19.390 --> 01:21.030 in different types of materials. 01:21.710 --> 01:29.060 A rubber tire looks different than a nice glossy finish to the car itself or the window. 01:29.340 --> 01:35.520 So we need to start to think about why do those materials behave that way and what properties they have 01:35.520 --> 01:37.770 that make them behave that way. 01:38.040 --> 01:42.000 The first thing we need to do before we start assigning those materials is making sure that we have 01:42.000 --> 01:44.070 Arnold loaded in. 01:44.070 --> 01:48.690 So we go down to Windows settings and preferences, plug and manager and scroll down to. 01:49.630 --> 02:01.270 The M to a bundle and to a just means Miha to Arnold, and Arnold is a rendering engine and basically 02:01.510 --> 02:03.490 there are different types of rendering engines. 02:03.760 --> 02:08.110 Mine used to have one called mental ray and that shipped with it. 02:08.110 --> 02:10.300 And now they've forgotten that one. 02:10.300 --> 02:13.420 And now they're using Arnold and their software. 02:13.720 --> 02:22.240 And you can also buy different types of renderers like V is something you might hear about RenderMan 02:22.240 --> 02:23.590 as something that Pixar made. 02:24.100 --> 02:31.390 And so there's all these different types of renders and they interpret light and surfaces differently. 02:31.780 --> 02:38.380 But basically they're all physically based renderers, meaning they tried to recreate the physics that 02:38.380 --> 02:40.090 we see in the real world. 02:40.600 --> 02:43.150 So this one is made by a solid angle. 02:43.150 --> 02:44.200 That's why it says Sottile. 02:44.200 --> 02:46.690 A solid angle is the company that makes Arnold. 02:47.110 --> 02:48.460 So we have that loaded now. 02:48.460 --> 02:52.870 So we're going to have the correct options that we need when we go to right. 02:52.870 --> 02:54.580 Click and say a sign of material. 02:54.880 --> 02:57.430 We're going to have the Arnold options available to us now. 02:57.700 --> 03:02.670 So we click on Shater, we can see that we can get the A.I. standard surface. 03:03.100 --> 03:07.090 And this is basically the one we're going to use the most. 03:07.420 --> 03:12.010 Arnold tries to condense everything you need into one shader. 03:12.520 --> 03:15.760 If you want to see the history of shaders, you can kind of look at the Miah shaders. 03:15.760 --> 03:24.490 If we go to the surfaces there, we can see and isotropic Blende, Lambert, Fong, Fong, e all of 03:24.490 --> 03:30.940 these shaders are kind of an evolution of what was created in 3D and they're named after the scientists 03:30.940 --> 03:31.920 that created them. 03:32.380 --> 03:38.140 So the evolution is such that we are now using Arnold. 03:38.470 --> 03:44.410 And the reason why I want to try to teach the why behind these is because this is going to change in 03:44.410 --> 03:45.010 the future. 03:45.040 --> 03:49.450 There's going to be a new renderer that comes out or they're going to change the one that's in my and 03:49.450 --> 03:50.350 you're going to have to adapt. 03:50.350 --> 03:51.490 This is part of learning. 03:51.490 --> 03:58.630 3D is always staying on top of what's current because I started with mental ray and that no longer exists. 03:58.630 --> 03:59.680 So I had to learn Arnold. 04:00.460 --> 04:06.280 So again, if we click on the object right, click and go down to assign new material, we get all of 04:06.310 --> 04:13.630 these options and we can isolate them by selecting them in the left side menu and we can see only the 04:13.630 --> 04:14.620 Arnold shaders. 04:14.980 --> 04:16.930 And so we want the A.I. standard service. 04:16.930 --> 04:23.140 When we click that, we can see we get a little more options here that takes over the screen and we 04:23.140 --> 04:24.280 can just reduce that down. 04:24.790 --> 04:33.070 And if we look at all of these A.I. standard surface attributes, we can see each one and they're kind 04:33.070 --> 04:34.440 of self-explanatory. 04:35.140 --> 04:40.690 Arnold has a lot of good documentation on this, but for the most part they mean what they say they 04:40.690 --> 04:41.080 mean. 04:41.110 --> 04:44.830 So the overall colour is going to be controlled by the base colour here. 04:45.520 --> 04:52.480 And and this is where you start thinking about the physical attributes of the material. 04:52.720 --> 04:59.050 So, for example, specular, something you may have never heard of is Ioana or incidents of refraction. 04:59.350 --> 05:01.540 This is an actual scientific no. 05:01.540 --> 05:06.820 You can look up for different types of materials so you can actually click on this and get different 05:06.820 --> 05:08.800 types of incidences of refraction. 05:09.130 --> 05:14.350 And this is usually dealing with more transparent materials like you can see here. 05:14.800 --> 05:19.450 But for our purposes, we can just leave it on one point five two, or we can choose something like 05:19.450 --> 05:23.500 plastic, something that's not going to have a ton of instances of refraction. 05:24.100 --> 05:27.250 So the roughness is like what it sounds. 05:27.250 --> 05:32.050 It's going to make a specular highlight be kind of rough and diffuse. 05:32.080 --> 05:35.860 If this is low, the specular highlight will be very sharp. 05:36.340 --> 05:41.950 So just start to think about those types of things and consider also the presets that we have up here 05:41.950 --> 05:43.000 to get you started. 05:43.270 --> 05:50.770 If you click on The Presets, you can get all these different types of presets, brush, metal and all 05:50.770 --> 05:54.100 these different types of things that we can use to get a good start. 05:54.400 --> 06:00.910 And then we can actually use this to kind of see what does Arnold use by default to show this type of 06:00.910 --> 06:01.360 a thing. 06:01.900 --> 06:08.110 We can also save our own presets here and use them for later and they will be down here. 06:08.500 --> 06:14.170 So let's just use brush metal and I'm going to click replace, which is just off the screen here. 06:14.560 --> 06:16.150 I can show that real quick. 06:17.060 --> 06:18.440 If we click presets. 06:19.460 --> 06:24.200 We can use brush metal and we can choose how much to blend with our current settings. 06:24.570 --> 06:28.670 I'm just going to replace everything and see where it gets us so we can see what it did. 06:28.670 --> 06:31.010 It changed metal allness all the way up to one. 06:31.400 --> 06:32.960 So this is a metal object. 06:33.380 --> 06:37.190 The weight is all the way to one and the color is kind of middle here. 06:37.470 --> 06:38.920 We might need to change that later. 06:39.440 --> 06:44.180 So let's just isolate this object and let's render it. 06:44.510 --> 06:48.190 If we render this thing, we aren't going to be able to see it. 06:48.620 --> 06:51.330 So we first need to add some lights. 06:52.190 --> 06:59.000 So in the next lesson, we're going to add some lights and learn how to adjust this material a little 06:59.000 --> 06:59.570 bit further. 06:59.630 --> 07:00.350 Thanks for watching.
