1 00:00:00,006 --> 00:00:01,006 - [Instructor] Hi, I'm George Mastry. 2 00:00:01,006 --> 00:00:02,009 If you're familiar with Unity, 3 00:00:02,009 --> 00:00:05,007 you probably know how to create terrain, 4 00:00:05,007 --> 00:00:10,006 but Unity has updated its terrain tools very recently. 5 00:00:10,006 --> 00:00:12,009 Now, these are still a preview release, 6 00:00:12,009 --> 00:00:15,002 but I thought I would show them to you 7 00:00:15,002 --> 00:00:16,008 so that you can get used to them, 8 00:00:16,008 --> 00:00:19,008 because they will become a part of Unity. 9 00:00:19,008 --> 00:00:23,003 So if you want to start off in the package manager, 10 00:00:23,003 --> 00:00:25,004 and there is a terrain tools. 11 00:00:25,004 --> 00:00:29,000 Now, I am recording in 3.02. 12 00:00:29,000 --> 00:00:31,009 You may have a later version for yourself, 13 00:00:31,009 --> 00:00:33,007 or it may be out of preview. 14 00:00:33,007 --> 00:00:38,001 So, that's what I'm using, and so I've already installed it. 15 00:00:38,001 --> 00:00:41,006 Now, when you install it, there's also this button here 16 00:00:41,006 --> 00:00:43,009 that says download asset samples. 17 00:00:43,009 --> 00:00:47,004 And when you do that, it basically brings up this window 18 00:00:47,004 --> 00:00:51,001 in the Unity store, and you can download those 19 00:00:51,001 --> 00:00:52,009 and install them, and I already have, 20 00:00:52,009 --> 00:00:54,005 and it includes a number of different 21 00:00:54,005 --> 00:00:57,008 brushes and textures that will help you get started 22 00:00:57,008 --> 00:01:00,003 with this really cool new tool. 23 00:01:00,003 --> 00:01:02,003 So go ahead and install everything, 24 00:01:02,003 --> 00:01:06,006 and then we'll go ahead and create some terrain. 25 00:01:06,006 --> 00:01:09,005 So we can create terrain in one of two ways. 26 00:01:09,005 --> 00:01:11,003 We can use the old fashioned way. 27 00:01:11,003 --> 00:01:15,000 So we can go into game object, 3D object, terrain, 28 00:01:15,000 --> 00:01:16,008 and create it that way. 29 00:01:16,008 --> 00:01:19,002 But we have a new window here. 30 00:01:19,002 --> 00:01:23,008 Under window, we have terrain, terrain toolbox. 31 00:01:23,008 --> 00:01:28,008 This allows us to create a new terrain of a custom size, 32 00:01:28,008 --> 00:01:31,005 allows us to tile that terrain. 33 00:01:31,005 --> 00:01:33,008 We can also import things such as height maps 34 00:01:33,008 --> 00:01:35,003 with that terrain. 35 00:01:35,003 --> 00:01:37,009 Now, when we create the terrain, it's going to create 36 00:01:37,009 --> 00:01:40,002 its own subfolder for all the terrains 37 00:01:40,002 --> 00:01:42,003 under assets slash terrain. 38 00:01:42,003 --> 00:01:43,009 If you want, you can change that. 39 00:01:43,009 --> 00:01:45,009 I'm going to leave it as it is. 40 00:01:45,009 --> 00:01:49,002 Then we can also change our terrain settings. 41 00:01:49,002 --> 00:01:51,003 If we want to, we can go into basic settings 42 00:01:51,003 --> 00:01:54,005 and basically just change whatever we want 43 00:01:54,005 --> 00:01:56,006 to make the terrain exactly the way we want. 44 00:01:56,006 --> 00:01:58,008 We also have some utilities, 45 00:01:58,008 --> 00:02:02,002 and some visualization modes as well. 46 00:02:02,002 --> 00:02:04,009 So I'm just going to start off with create new terrain, 47 00:02:04,009 --> 00:02:06,007 and let's go ahead and hit create. 48 00:02:06,007 --> 00:02:10,000 So I'm just going to leave it at the defaults of 500, 49 00:02:10,000 --> 00:02:14,002 and we're going to create it at the origin. 50 00:02:14,002 --> 00:02:17,008 So when I do, it creates this terrain. 51 00:02:17,008 --> 00:02:20,003 Now, a terrain is basically just a blank pallette 52 00:02:20,003 --> 00:02:22,009 onto which we can sculpt the terrain. 53 00:02:22,009 --> 00:02:25,007 So it also creates this terrain group, 54 00:02:25,007 --> 00:02:27,007 and then in that terrain group, 55 00:02:27,007 --> 00:02:30,008 you can paint into the terrain. 56 00:02:30,008 --> 00:02:33,006 Now, there's a couple of buttons here in the terrain. 57 00:02:33,006 --> 00:02:36,004 If we go into the inspector, you'll see we have 58 00:02:36,004 --> 00:02:38,008 the ability to create neighboring terrain. 59 00:02:38,008 --> 00:02:41,001 So if I click on one of these edges, 60 00:02:41,001 --> 00:02:43,002 it creates another terrain. 61 00:02:43,002 --> 00:02:45,004 Now, I don't really need that, but if you want to create 62 00:02:45,004 --> 00:02:47,006 a bigger space, you can certainly add in 63 00:02:47,006 --> 00:02:51,003 as many terrains as you feel is necessary. 64 00:02:51,003 --> 00:02:52,008 But we're going to focus a little bit more 65 00:02:52,008 --> 00:02:55,003 on painting and sculpting terrain. 66 00:02:55,003 --> 00:02:57,007 So we've got a number of tools here. 67 00:02:57,007 --> 00:03:01,002 We have sculpt tools, we have effects, we have stuff 68 00:03:01,002 --> 00:03:04,000 like erosion, but probably the most important one 69 00:03:04,000 --> 00:03:06,001 is raise or lower terrain. 70 00:03:06,001 --> 00:03:07,004 So you want to select that, 71 00:03:07,004 --> 00:03:08,009 and then we have a number of brushes. 72 00:03:08,009 --> 00:03:11,003 Now, some of these brushes came in with that pack 73 00:03:11,003 --> 00:03:14,003 that we installed, so I'm going to go ahead and just select 74 00:03:14,003 --> 00:03:15,008 one of the default brushes here, 75 00:03:15,008 --> 00:03:19,006 which is basically just this kind of circle shape. 76 00:03:19,006 --> 00:03:21,004 And as you can see, as I hover over it, 77 00:03:21,004 --> 00:03:22,007 it gives you kind of an impression 78 00:03:22,007 --> 00:03:24,007 as to what that brush will do. 79 00:03:24,007 --> 00:03:28,003 Now, the brush itself has a brush strength, 80 00:03:28,003 --> 00:03:30,006 as well as jitter. 81 00:03:30,006 --> 00:03:32,004 We also have a brush size, 82 00:03:32,004 --> 00:03:34,001 so you can change the brush size here. 83 00:03:34,001 --> 00:03:36,005 So if I want a bigger brush or a smaller brush, 84 00:03:36,005 --> 00:03:38,000 I can do that. 85 00:03:38,000 --> 00:03:41,001 Now, if I want, I can also just click on it, 86 00:03:41,001 --> 00:03:43,004 and it will go ahead and make it that size. 87 00:03:43,004 --> 00:03:46,007 If I click and hold and drag, you'll see that it basically 88 00:03:46,007 --> 00:03:48,009 makes it bigger and bigger. 89 00:03:48,009 --> 00:03:51,002 Now, I have a number of really cool brushes here 90 00:03:51,002 --> 00:03:53,000 that I can use, so if I want to, 91 00:03:53,000 --> 00:03:56,003 I can create some mountains here. 92 00:03:56,003 --> 00:03:58,008 So I'm really just selecting these tools at random, 93 00:03:58,008 --> 00:04:03,001 and you can kind of see how they work. 94 00:04:03,001 --> 00:04:06,008 And I can start to paint my terrain the way that I want. 95 00:04:06,008 --> 00:04:10,005 Now, if I want to go back and modify it, I can. 96 00:04:10,005 --> 00:04:12,003 I can select the tool here, 97 00:04:12,003 --> 00:04:16,004 and if I hold down the control key. 98 00:04:16,004 --> 00:04:19,003 it will go ahead and kind of lower that terrain. 99 00:04:19,003 --> 00:04:21,009 Or basically, it's kind of like the erase key. 100 00:04:21,009 --> 00:04:23,004 And if I just left click, 101 00:04:23,004 --> 00:04:26,001 it'll go ahead and raise that terrain. 102 00:04:26,001 --> 00:04:29,002 Now, some of this is going a little bit out of control, 103 00:04:29,002 --> 00:04:32,005 so what we want to do is keep our brush strength fairly low, 104 00:04:32,005 --> 00:04:34,008 especially if you're working with a mouse. 105 00:04:34,008 --> 00:04:37,005 Now, if you're working with a pen or something like that, 106 00:04:37,005 --> 00:04:41,001 or some sort of WACOM tablet, then you'll have a little bit 107 00:04:41,001 --> 00:04:43,005 more control with the pressure. 108 00:04:43,005 --> 00:04:45,006 Now, in addition to raising and lowering terrain, 109 00:04:45,006 --> 00:04:47,006 we can also smooth that terrain. 110 00:04:47,006 --> 00:04:50,008 And again, that brush strength is really important. 111 00:04:50,008 --> 00:04:52,007 I tend to set mine fairly low 112 00:04:52,007 --> 00:04:55,004 and then just go over it a few times. 113 00:04:55,004 --> 00:04:59,001 Now, we also have the ability to add in 114 00:04:59,001 --> 00:05:01,004 all sorts of effects, so if I want to, 115 00:05:01,004 --> 00:05:04,003 I can create what's called a terrace. 116 00:05:04,003 --> 00:05:07,000 So by going along this edge here, 117 00:05:07,000 --> 00:05:08,008 you can see that it's creating kind of, like, 118 00:05:08,008 --> 00:05:12,008 a terraced hillside effect, which is kind of neat. 119 00:05:12,008 --> 00:05:16,000 I can create effects, so if I wanted to, 120 00:05:16,000 --> 00:05:18,000 I can sharpen the peaks. 121 00:05:18,000 --> 00:05:19,004 Let's say I do that on this one. 122 00:05:19,004 --> 00:05:21,006 It's basically sharpening that. 123 00:05:21,006 --> 00:05:26,006 I can flatten a slope, so that's basically, and again, 124 00:05:26,006 --> 00:05:28,007 I want to keep my brush strength fairly low on this, 125 00:05:28,007 --> 00:05:31,008 but what I can do is I can kind of slope that out 126 00:05:31,008 --> 00:05:35,008 to kind of make a sort of erosion sort of effect. 127 00:05:35,008 --> 00:05:38,004 And we also have erosion effects, so if I want to, 128 00:05:38,004 --> 00:05:41,000 I can create, like, a hydraulic effect. 129 00:05:41,000 --> 00:05:45,005 So there's a number of different tools that you can use. 130 00:05:45,005 --> 00:05:50,000 So as you can see, Unity's new terrain tools are very robust 131 00:05:50,000 --> 00:05:52,007 and they really allow you to sculpt the terrain 132 00:05:52,007 --> 00:05:54,007 exactly the way that you want.
