WEBVTT 00:00.150 --> 00:04.590 In this lesson, we're going to take the knowledge that we've learned so far and put it to use to add 00:04.590 --> 00:06.390 some more details of the Ghostbuster trap. 00:06.950 --> 00:08.640 We take a look at the Arnold Run interview. 00:08.940 --> 00:14.700 We can see that the brush metal that we made is pretty standard. 00:14.700 --> 00:15.870 It's pretty clean. 00:16.350 --> 00:18.750 There's no rough marks on it. 00:18.750 --> 00:24.180 And it looks like this Ghostbuster trap has never been used to actually catch ghosts. 00:24.450 --> 00:28.620 So let's add a little more detail to this brush metal. 00:28.710 --> 00:34.460 We're going to do that by adding a new shader to this with using a 3D paint as a mask. 00:34.830 --> 00:37.040 So let's first create the 3-D paint. 00:37.410 --> 00:40.770 So let's open up the Hypercharged so we can keep track of what we're doing here. 00:41.160 --> 00:47.190 I'm clicking the little hypercharged button up here that should pop open and we can see our brush metal 00:47.190 --> 00:50.230 here and we have to. 00:50.280 --> 00:56.240 So if you remember, we made one for this panel and then these two have different kinds. 00:56.670 --> 01:01.910 So if we click this little button here, we can map it out and see that it's the original brushed metal. 01:02.490 --> 01:07.470 So let's leave that up and let's also create a Lambert. 01:07.890 --> 01:12.870 And any time we're in the Hypercharged, we we can create new materials and, you know, they're not 01:12.870 --> 01:13.770 applied to anything yet. 01:13.770 --> 01:15.330 So we still have to apply them. 01:15.690 --> 01:22.950 But let's select the object and we can either middle mouse drag it and let go over on top of it, or 01:22.950 --> 01:27.380 we can right mouse click and go to assign material to a viewport selection. 01:27.840 --> 01:29.640 And when we let go, it'll be assigned. 01:29.640 --> 01:34.650 And the reason why we're doing this right now is because we're going to do some three painting like 01:34.650 --> 01:35.940 we did in the previous lesson. 01:36.240 --> 01:41.100 But of course, it only works on the Miah shader, so we need to apply my shader before we do it. 01:41.490 --> 01:50.880 So let's click the three paint tool and we need to, of course, assign the texture to it. 01:50.880 --> 01:54.620 And for KS, fine and JPEG is OK. 01:54.960 --> 01:56.370 So now we can start painting. 01:56.820 --> 02:05.970 Let's first flooded with a color, let's go to a white color and we'll just flood that paint and then 02:05.970 --> 02:08.370 let's do a black because we're going to create a mask. 02:08.370 --> 02:10.200 So we want black and white values. 02:10.200 --> 02:12.240 Basically that's all we need. 02:12.240 --> 02:13.260 We don't need any color. 02:13.680 --> 02:17.700 And we're going to take a look at this section here. 02:17.700 --> 02:23.100 We can click the folder and it should go right to your brush shapes folder. 02:23.400 --> 02:30.180 And if we can preview them, we can see there's all these different types of kind of stencils that we 02:30.180 --> 02:30.990 could be using. 02:31.260 --> 02:42.000 So we're going to use this for the to create a mask here so that when we paint, it looks a little more 02:42.000 --> 02:42.630 organic. 02:42.840 --> 02:48.320 So this is a new kind of part to this same tool that we're getting familiar with. 02:48.690 --> 02:51.540 So I've got black, I've got the paint turned on. 02:51.750 --> 02:52.890 We've assigned the thing. 02:52.890 --> 02:54.750 So now I can start painting. 02:55.320 --> 03:01.650 And what I'm looking to do is add rust to certain areas. 03:02.010 --> 03:09.180 And right now this black area is going to reveal a new shape that we're going to make with a mix shader. 03:09.750 --> 03:14.760 So let's take a second and paint some rust where we want rust on this panel. 03:40.560 --> 03:46.680 So now that we have where we want the rest to show we can save this texture out like we did previously 03:46.680 --> 03:57.180 by clicking the save texture button, and now that we have that texture, we can reapply the material 03:57.180 --> 04:02.160 from the hyper shade and we can do a lot of work from the shade itself now. 04:02.530 --> 04:07.260 So let's bring that brush medal in the original material that we had. 04:10.100 --> 04:18.780 Let's get a to focus in on everything that's we have so we currently have this texture that we just 04:18.780 --> 04:22.140 created, we can see that because it's a part of the Lambert. 04:22.140 --> 04:27.840 If we map out the Lambert, we can see that there is a texture going into the color. 04:28.380 --> 04:30.120 So we see our color color. 04:30.420 --> 04:32.850 So we know that this is the actual file. 04:33.150 --> 04:39.660 If we click on it and go to the OR we can actually see that right clicking here and we can see it populate 04:39.660 --> 04:41.470 in the sample area here. 04:41.970 --> 04:47.580 So now we know this is the file that we want, but we want it to apply on the brush metal, but not 04:47.580 --> 04:48.990 necessarily to the brush metal. 04:49.000 --> 04:51.420 We want to mix in a different shader. 04:51.700 --> 04:54.060 So let's go about making that rust shader first. 04:54.360 --> 04:57.090 So let's apply a new shader that's going to be our rush shader. 04:57.090 --> 05:02.890 We'll go assign new material and we'll go down to the Arnold shaders and pick a standard surface. 05:03.300 --> 05:05.790 So it's going to bring it in here in the hypothecate as well. 05:05.790 --> 05:11.460 And we can just map this out and let's first create the color that we want. 05:11.460 --> 05:13.500 Let's make it like a brown type of a color. 05:17.000 --> 05:21.110 And now let's open up the Arnold Render review so we can see the changes that we're making in real time 05:21.430 --> 05:25.040 that play on the play button here so we can see we kind of pretty basic, Qadar. 05:25.040 --> 05:29.510 It's just a brown shader and we want to add some bump to it. 05:29.510 --> 05:34.280 So let's create a bump map by clicking the checker box and go to the noise tab. 05:34.700 --> 05:39.560 And if we zoom in, we can kind of see there's some noise starting to happen. 05:39.560 --> 05:40.490 But it's really big. 05:40.490 --> 05:41.540 It's really spread out. 05:41.550 --> 05:46.580 So let's go into the bump itself and increase the ratio. 05:49.960 --> 05:56.450 And let's increase the frequency ratio as well, and as we do that, you can see a change here so we 05:56.450 --> 06:01.790 can right click and get a sample and we'll have to refresh that more as we update it. 06:02.040 --> 06:09.350 So I'm just reducing the amplitude so that it's all kind of evenly noise distributed here. 06:09.890 --> 06:18.610 And it's looking pretty good so far, but it looks like we might have gone too strong on the noise potentially. 06:19.070 --> 06:23.060 Let's go back into the bump map and change that to point five. 06:24.440 --> 06:26.120 So that reduces it down a little bit. 06:26.120 --> 06:30.110 And it might also be the reflections are throwing us off. 06:30.140 --> 06:31.040 So let's go back. 06:31.280 --> 06:35.540 I'm just clicking these buttons to go in and out of the shader. 06:35.540 --> 06:40.850 We could also click the different parts of it from the hyper shade to navigate around. 06:40.850 --> 06:46.700 So I'm going back to the shader here and let's take a look at the specular. 06:46.970 --> 06:52.160 Let's increase the roughness, because if we think about rust, rust is pretty rough. 06:52.730 --> 06:54.590 So now that's looking a lot better. 06:55.610 --> 07:00.260 And we could even apply a fractal to this rust if we wanted. 07:01.430 --> 07:07.250 But for right now, let's just leave it as it is and we can come back to it if we'd like. 07:07.740 --> 07:17.600 So we have the rust and we have the bump map here that gives it some texture. 07:18.410 --> 07:20.300 Let's maybe increase that just a little bit. 07:27.670 --> 07:34.180 So how do we combine the two shaders, we have this Shater and we have that Shater, so there's a new 07:34.180 --> 07:40.570 node called the mixed node and if we type in EHI, it'll bring up all the Arnold shaders. 07:40.990 --> 07:49.090 And if we type in A.I.M., it'll bring up the I mix shader here. 07:49.390 --> 07:54.460 You can also get to it just from going into the shader options and just kind of scrolling down on Arnold 07:54.460 --> 07:54.750 here. 07:55.240 --> 07:58.040 So if we scroll down, we can see Amik shader. 07:58.840 --> 08:03.340 So now let's apply this to the object. 08:03.670 --> 08:04.900 I'll select it and. 08:04.900 --> 08:05.230 Right. 08:05.230 --> 08:06.280 Click and say. 08:09.510 --> 08:15.570 And right click and say assigned material to viewport selection, and you can see it's just kind of 08:15.570 --> 08:17.370 black because there's nothing going into it. 08:17.730 --> 08:20.400 If we look at the shader here and that be. 08:20.570 --> 08:23.640 Ed, it's asking for two Qader should or one or two. 08:23.880 --> 08:28.530 And the mix wait is at point five, which means it's going to blend between these two shaders, but 08:28.530 --> 08:30.060 they're currently empty, so we need to fill them. 08:30.480 --> 08:35.670 So we have the standard surface here, which we're going to call the rust. 08:35.670 --> 08:37.020 So it's labeled rust. 08:40.450 --> 08:47.860 And let's select the mix, Qader and a middle mouse drag the rust into Qader one and now you can see 08:48.100 --> 08:49.750 it's back to how he had it. 08:51.520 --> 08:53.100 So let's bring in the brush metal. 08:53.410 --> 08:56.380 We have the brush metal up here somewhere. 08:56.500 --> 08:59.050 Or maybe we got rid of it so that we can just bring it in here. 08:59.650 --> 09:00.480 Brush metal. 09:00.490 --> 09:03.100 We can just minimize, drag it from there and let go. 09:04.420 --> 09:11.020 So now it's just mixing 50/50 so we can drag this and see it go from one to the other. 09:11.650 --> 09:15.090 But if you remember, we have that texture, so let's use it. 09:15.340 --> 09:17.650 We painted it here. 09:17.650 --> 09:21.550 So let's middle mouse drag the texture into the mix weight. 09:22.330 --> 09:23.440 And as soon as we do that. 09:25.870 --> 09:33.670 We should get a change here and not a lot happened, so let's look at why that might be. 09:36.650 --> 09:42.170 First, it could be because we swapped our values white for black, but also it could be because the 09:42.170 --> 09:44.230 blacks aren't black enough that we painted. 09:44.570 --> 09:50.630 So let's if you remember from a previous lesson, the alpha is luminance is really important, because 09:50.630 --> 09:57.650 if you look at what's actually getting piped in here to the mix, it is the let's let's organize this 09:57.650 --> 09:58.460 a little bit better. 10:01.880 --> 10:07.430 You can click this rearranged button to kind of sort everything out a little bit better, so it's this 10:07.430 --> 10:08.750 little arrow button here. 10:09.890 --> 10:13.560 So now so now we can get a better look at what's going into the mix. 10:13.580 --> 10:16.310 We can see it's the alpha that's actually going into the mix. 10:16.310 --> 10:22.220 And if you remember from previous lesson, the Alpha, there is no alpha here. 10:22.220 --> 10:23.600 It's just black and white. 10:23.600 --> 10:27.860 So we need to tell it that the black and white value is the alpha. 10:28.100 --> 10:31.540 Or we could just map in one of the three channels here. 10:31.820 --> 10:35.150 So if we do that, we can just kind of circumvent the alpha thing. 10:35.150 --> 10:40.380 And now we can see the painting that we did is revealing the rust shader beneath it. 10:40.880 --> 10:50.300 So, again, the advantage of using the Alpha is that we have these alpha color balance sliders here 10:50.300 --> 10:56.930 so that if we choose Alpha is luminance, we get back to the same result that we just had. 10:56.930 --> 10:59.920 If we were just piping in one of the red, green or blue channels. 11:00.620 --> 11:07.060 So now that it's alpha, we can increase this or decrease this with the alpha gain and the alpha offset. 11:07.850 --> 11:09.100 So that's pretty helpful. 11:09.320 --> 11:14.660 But let's say maybe this doesn't go far enough and we want it to affect it even more. 11:15.020 --> 11:18.770 We could add a color, correct note. 11:19.550 --> 11:24.740 We can click on the shader here under Arnold and get to the color. 11:24.740 --> 11:25.580 Correct note. 11:25.940 --> 11:31.910 If we click that, it'll load it in and we can just pipe in the alpha from this 11:34.250 --> 11:40.670 image into the color correct node and now the alpha into the mix. 11:40.970 --> 11:45.680 So we're just kind of putting this in the middle of that stream there. 11:45.680 --> 11:50.450 So now it has to go through the color correct node so that now with the color correct node, we have 11:50.450 --> 11:52.040 all these different options. 11:52.040 --> 11:53.900 Now, we could change the gamma. 11:55.550 --> 12:00.560 Which if we piped in the Red Channel, this would be red, this would be green, this would be blue. 12:00.560 --> 12:05.030 So this would be a way if we did pipe in the Red Channel that we could actually affect that. 12:05.600 --> 12:12.100 And so we can increase the alpha gain or alpha offset here as well. 12:12.530 --> 12:16.730 So that's another level of adjustment that we could have. 12:17.150 --> 12:20.240 So that's how you add more detail and realism with the mix shader. 12:20.480 --> 12:22.210 Thanks for watching and I'll see you in the next lesson.
