WEBVTT 00:00.480 --> 00:05.580 In this lesson, we're going to talk about procedural texturing and texture, the other side of this 00:05.580 --> 00:11.700 door panel with a procedural texture, I'm just going to hide this light for now or actually, I can 00:11.700 --> 00:14.220 go to show and turn off lights. 00:14.220 --> 00:20.040 If I was to use control to hide the light, then in the render it would also hide it and we would have 00:20.040 --> 00:21.060 no lights in our scene. 00:21.630 --> 00:29.030 So I'm going to click this door panel and again assign a new shader by right clicking going to assign 00:29.040 --> 00:34.260 a material, go to Arnold tab and go down to a standard surface. 00:34.560 --> 00:39.720 Now in the color option, when I click this, instead of choosing a file like we did when we want to 00:39.780 --> 00:46.260 type in a texture, we can use really anything we could use a fractal we could use any of these. 00:46.260 --> 00:48.120 All of these are procedural textures. 00:48.120 --> 00:48.480 Right. 00:48.870 --> 00:57.600 And we could actually isolate these by using the texture option here, which Arnold has their own noize 00:58.590 --> 00:59.340 textures. 00:59.670 --> 01:02.370 We could use the 2D textures from Myia. 01:02.760 --> 01:05.550 We don't have to we're not isolated just to Arnold textures here. 01:05.550 --> 01:06.480 We could use anything. 01:06.960 --> 01:08.820 And what I want to use here is a ramp. 01:09.210 --> 01:16.290 So when I click a ramp and we can see that if we click and drag these top little circles, that it is 01:16.620 --> 01:17.610 indeed working. 01:18.450 --> 01:19.770 And this is a V ramp. 01:20.100 --> 01:21.990 So it's going up and down. 01:21.990 --> 01:28.680 It looks like if we click on this and go to the movie editor, which we know all about UVs now, I just 01:28.680 --> 01:29.430 close that. 01:29.970 --> 01:33.390 We can kind of see which direction it's going in. 01:33.390 --> 01:37.500 And the movie editor as well, we can see it's kind of going up and down here. 01:37.500 --> 01:38.710 And that's the V ramp. 01:38.850 --> 01:43.530 If you remember from the previous lessons, V is vertical, so. 01:45.660 --> 01:48.130 There's a couple different ways we could adjust this. 01:48.660 --> 01:54.120 I'm just going to delete the history on this as well, because we have a lot of history still left over 01:54.120 --> 01:55.440 from the previous lessons. 01:56.710 --> 02:02.230 And now we can get to the Shater a lot quicker, so if I go back to the ramp here. 02:03.800 --> 02:10.380 I can change this to a new ramp and now it's going up and down, but we want a diagonal ramp somewhere 02:10.380 --> 02:15.130 to choose diagonal and it's a very soft transition here. 02:15.770 --> 02:18.590 You can see how this is kind of a gradient. 02:19.010 --> 02:23.510 We can change that by going to none so that there's no interpretation between the two. 02:24.320 --> 02:26.210 And we're getting a little bit of us here. 02:26.210 --> 02:29.540 But that's just because of the viewport. 02:29.790 --> 02:31.820 Hopefully when we render this, that should be gone. 02:31.820 --> 02:36.860 And we can also check that real quick just by going into the Arnold render view and hitting play. 02:37.940 --> 02:41.390 And now you can see this is a very hard line as a straight line. 02:41.900 --> 02:44.900 So don't be deceived by what you see here. 02:44.900 --> 02:50.420 Exactly, because in the final render, it might be slightly different based on because this is the 02:50.420 --> 02:52.640 high resolution kind of render that we're going for. 02:53.240 --> 02:58.160 So close that down that I know that's acting in the way that I want it to. 02:58.730 --> 03:01.040 And I'm going to change this color to a yellow. 03:01.400 --> 03:02.270 I could actually. 03:02.420 --> 03:04.010 So I'm clicking on this selected color. 03:04.010 --> 03:08.150 I'm clicking on the white area here, and that'll bring up the color history. 03:08.150 --> 03:14.060 And I can use the picture and actually match this color here that we already have so that I'm being 03:14.060 --> 03:14.750 consistent. 03:14.990 --> 03:17.240 I can move the position with these. 03:17.930 --> 03:23.360 I can add new color here by clicking anywhere and it'll add another color of itself, which I could 03:23.360 --> 03:24.500 change if I wanted to. 03:25.160 --> 03:30.380 But I want to keep that the same and start repeating these pieces here so you can see how very quickly 03:30.650 --> 03:32.360 I can just add new lines. 03:32.360 --> 03:33.860 I can change the thickness of them. 03:34.340 --> 03:40.490 I could even animate these things positions if I wanted to, so the ramp itself would animate. 03:41.060 --> 03:43.790 But very quickly, you can see, you know what? 03:43.790 --> 03:46.820 If you change your mind, you don't have to go to a new program. 03:46.820 --> 03:52.730 You can procedurally change this so that it will update as you want it to. 03:53.360 --> 03:58.040 And so that's quite powerful. 03:59.090 --> 04:04.910 When you compare the two, you can also combine them in certain ways and you can do a little more advanced 04:04.910 --> 04:05.210 things. 04:05.210 --> 04:12.560 But just for now, it's important to understand the concept between using a file which is kind of baked 04:12.560 --> 04:14.270 down and you cannot adjust. 04:14.270 --> 04:14.690 And Maya. 04:14.690 --> 04:14.990 Right. 04:14.990 --> 04:20.780 It's just using this file and the difference between a procedural texture, which if you click on this 04:20.780 --> 04:23.780 and go to, there's all these options that we can actually change it. 04:23.780 --> 04:25.580 We can actually add noise to it. 04:25.880 --> 04:28.100 We could do all these different types of things to it. 04:28.100 --> 04:34.970 And I just want to show you the power of that and encourage you to explore the different procedural 04:34.970 --> 04:37.430 textures, the 2D textures, the fractals. 04:37.910 --> 04:43.760 And we're going to dig a little deeper into those in the next lessons as we refine the shape. 04:44.210 --> 04:49.940 But in the meantime, I'm going to encourage you to finish out the texture here one way or the other. 04:50.270 --> 04:53.870 And let me just show you one real quick trick. 04:54.200 --> 05:01.040 So I'm going to go with the procedural for this example, and I'm going to go assign it real quick. 05:01.520 --> 05:07.550 So I'm just going off of the assigned existing material and we're going I'm just going off the screen. 05:07.550 --> 05:09.560 Just a touch to get that one. 05:10.070 --> 05:13.100 So this is an accurate to the reference. 05:13.100 --> 05:16.010 They should be going in the same direction like this. 05:16.610 --> 05:21.050 So what I could do is actually change the moves. 05:21.500 --> 05:23.240 So if I open the movie, Ed. 05:26.120 --> 05:35.000 And I can just grab the UV tool kit and Dockett here on the side and I'm going to reduce this down so 05:35.000 --> 05:42.830 I can see it what's happening and we can use the transform attributes to rotate this around. 05:44.360 --> 05:48.680 And see where it needs to be to line up. 05:50.380 --> 05:54.970 So I can just drag this to try to get this to the correct. 05:56.800 --> 06:01.150 Length and lines that it lines up with. 06:02.940 --> 06:04.170 So it appears. 06:06.050 --> 06:11.070 That this one may get cut off at the bottom here because it's diagonal doesn't continue. 06:11.570 --> 06:12.710 Exactly right. 06:13.040 --> 06:20.150 So what we need to do is tile this image in a different way so that these will line up exactly as we 06:20.150 --> 06:20.580 need them. 06:21.120 --> 06:28.490 So want to introduce you to another component of texture's, which is the texture placement. 06:28.890 --> 06:35.790 If I go to the object mode, select this and we select these one of these two. 06:36.230 --> 06:45.920 This is basically the input and output of this node so we can go to the ramp and see its place to add 06:45.920 --> 06:51.800 texture here so we can see the placement of the texture. 06:52.010 --> 06:55.580 And instead of adjusting the IVs, we can actually adjust it from here. 06:55.610 --> 06:59.030 But because they're using the same. 07:00.070 --> 07:06.010 Texture, we can't really rotate because it rotate both of them, so we move the moves, but we still 07:06.010 --> 07:11.410 have this problem and that's just because it's wrapping it the wrong way, we want to mirror that. 07:11.410 --> 07:19.960 So now we have that one's done and it we no longer have it where it's cutting it off because it's mirroring 07:19.960 --> 07:26.890 the bottom instead of repeating it, because you can see what it's trying to do is start back up from 07:26.890 --> 07:31.750 the top, basically, and instead of repeating or sorry, mirroring the bottom. 07:31.750 --> 07:35.230 So we mirror the bottom, we'll get rid of that little thing. 07:35.770 --> 07:45.460 But so this is how we can procedurally texture the door panels to have the same file texture. 07:45.760 --> 07:48.280 And we can adjust this through the shader. 07:48.290 --> 07:54.550 We can also, you know, tweak the UVs of this thing so d line up or they don't line up. 07:55.330 --> 08:01.150 You know, however you want to be kind of add realism by offsetting some things a little bit, not making 08:01.150 --> 08:02.140 it look too perfect. 08:03.340 --> 08:07.720 But yeah, that's kind of a good introduction to procedural texturing. 08:07.720 --> 08:08.710 Why that's important. 08:09.010 --> 08:15.160 And we're going to look at using procedural textures more in the next lessons to add a little more realism 08:15.160 --> 08:17.650 to the shaders that we have already assigned. 08:17.800 --> 08:18.520 Thanks for watching.
