WEBVTT 00:00.090 --> 00:07.440 Welcome to the first lesson on rigging, where we all cover one of the quick rig tools and discuss what 00:07.440 --> 00:12.990 is rigging, why it's important and why we need to learn it, basically, if we're going to animate 00:12.990 --> 00:17.310 this guy and we have a model here, how do we go about animating it? 00:17.340 --> 00:19.080 There's no way to control it. 00:19.080 --> 00:22.590 It's just a bunch of vertices and faces. 00:22.950 --> 00:29.400 We could maybe try to go in here and set keys on vertices and not be very inefficient if we just picked 00:29.400 --> 00:33.330 certain vertices and tried to move them around, try to create a pose. 00:33.330 --> 00:39.450 You can quickly see we'll get off model, which when we're talking about 2D animation, they always 00:39.450 --> 00:40.140 have to worry about. 00:40.140 --> 00:43.380 And they had model sheets to make sure that you never got off model. 00:43.380 --> 00:48.780 And the volume of the character was always the same, each frame that you drew it while 3D animation. 00:48.780 --> 00:54.060 What we need to worry about is not so much keeping the character on model, but using the model that 00:54.060 --> 00:55.680 we have in a way that we can animate it. 00:55.680 --> 01:01.380 And that's what rigging is, is basically adding a skeleton to this piece of geometry. 01:01.920 --> 01:03.360 So we need to add a skeleton to it. 01:03.360 --> 01:03.980 How do we do that? 01:03.990 --> 01:07.800 There's a couple of different ways and we'll start with the simplest way. 01:08.070 --> 01:13.410 We'll go up here to the rigging tab and we'll go to skeleton. 01:14.530 --> 01:15.280 Quick, rigt. 01:16.820 --> 01:22.850 We'll open up a new window here, and you can see that we actually have just a one click solution here. 01:23.240 --> 01:28.310 And luckily for us, this model will work decently well with this. 01:28.610 --> 01:29.930 Depending on the model you have. 01:30.530 --> 01:35.060 Definitely feel free to open up this scene and follow along so you have this model and can play with 01:35.060 --> 01:35.590 it as well. 01:35.600 --> 01:41.600 Once we get going here, someone hit auto rig and it'll say we need to choose a mesh first. 01:41.600 --> 01:43.880 So we need to select them and then click the button. 01:47.210 --> 01:51.770 Now, you can see a lot of things just happened and it makes the model look a lot more complicated. 01:53.000 --> 01:54.290 You can see the outline or two. 01:54.290 --> 01:55.220 A lot of things were added. 01:55.550 --> 01:58.610 There's a new icon over here, a couple of new ones. 01:58.880 --> 02:03.650 This purple one is a joint and that has all the joints in here. 02:03.980 --> 02:09.620 And they're indicated by these yellow pieces here that are kind of these triangles with circles at the 02:09.620 --> 02:09.950 end. 02:10.340 --> 02:14.320 And right away you can see that there's a few errors. 02:14.330 --> 02:16.780 You can see that didn't place the elbow in the right place. 02:16.790 --> 02:19.370 Elbows more in the forearm here should be up here. 02:19.670 --> 02:24.440 But for our purposes, just so you get an idea of like what rigging is, we're going to use this quick 02:24.440 --> 02:26.630 rig to a real quick for discussion purposes. 02:27.050 --> 02:28.960 So we've rigged this thing. 02:29.300 --> 02:36.620 So what happened is it added bones and then it weighted the mesh to these bones. 02:37.100 --> 02:43.460 And that means that each one of these vertices was giving a value to say, you know, especially in 02:43.460 --> 02:46.820 the spine here where we have a lot of different bones together. 02:47.150 --> 02:53.500 This vertices here might be weighted to this joint, maybe 80 percent and maybe 20 percent of this joint. 02:53.510 --> 03:01.160 And so it'll have a value of zero to one, which is represented by a color that we'll see later of black 03:01.160 --> 03:01.760 to white. 03:02.090 --> 03:06.680 And it basically says, you know, follow this joint this much. 03:07.370 --> 03:12.200 So once we start moving this, it will be a smoother transition between joints. 03:12.590 --> 03:16.850 So let's grab the end a handle here for the hand. 03:17.270 --> 03:21.080 And as soon as you start moving that around now, we can actually control the character. 03:21.770 --> 03:23.840 And you can see it's not ideal. 03:24.290 --> 03:29.300 Like I said, the elbow's in the wrong place, but you can get a sense of why rigging is important and 03:29.300 --> 03:30.140 how it's going to work. 03:30.410 --> 03:33.440 We're basically going to create a series of joints. 03:33.830 --> 03:37.250 Then we're going to weight the mesh to the joints and then we're going to need a way to control the 03:37.250 --> 03:38.180 joints themselves. 03:38.180 --> 03:40.010 And that's what these nerve's curves are. 03:40.250 --> 03:41.900 And we haven't used them very much. 03:42.110 --> 03:47.180 And the first modeling course, we use them a little bit, but we can use these as actually control 03:47.180 --> 03:53.780 guides that we can select and manipulate, because just like we don't want to be manipulating the vertices 03:53.780 --> 03:59.440 on the mesh, we also don't want to be setting keyframes on the joints themselves. 03:59.780 --> 04:03.200 We want all that keyframe animation to be on a control. 04:03.560 --> 04:09.410 And so that way that we can actually go to show and hide the joints. 04:09.680 --> 04:15.080 So that only thing that we're going to deal with and so that we don't accidentally select the joints 04:15.080 --> 04:17.120 is just the control rig. 04:17.390 --> 04:19.310 And that's what all of these little points are. 04:19.520 --> 04:23.750 So we can start to see how we can manipulate the model. 04:23.750 --> 04:31.070 And we can also see the problems with the quick rig tool is the the joints aren't necessarily exactly 04:31.070 --> 04:32.000 how we need them to be. 04:32.270 --> 04:37.460 We also have no fingers and the foot is a little generic. 04:37.790 --> 04:44.000 There's no way to really roll the foot off of the toe or the ball, the foot and the natural way that 04:44.060 --> 04:45.230 that someone would walk. 04:45.410 --> 04:47.210 Currently we can just move it around. 04:47.660 --> 04:51.350 But there's no way to pivot the foot off of the ball. 04:51.620 --> 04:53.150 So of the foot. 04:53.150 --> 04:55.370 So we need to address that. 04:55.370 --> 05:00.140 And this is also I'm explaining all of this, the reasons why we're going to make our own custom rig 05:00.140 --> 05:05.390 with joints, eh, so we can learn the entire process because not every character is going to be the 05:05.390 --> 05:05.780 same. 05:05.990 --> 05:10.070 You're going to have, you know, human characters like a bipedal character like this. 05:10.340 --> 05:15.830 You're going to have quadrupeds are going to have aliens, you know, even props, which is what we're 05:15.830 --> 05:19.400 going to start with so we can understand some of the basic concepts of rigging. 05:20.000 --> 05:25.490 But I wanted to just introduce you to this real quick so you can kind of actually have something to 05:25.490 --> 05:29.600 play with very quickly in the first few minutes of opening up Maya and the scene. 05:29.630 --> 05:32.360 So take a minute and kind of play around with this. 05:32.690 --> 05:38.960 The other thing I'll also say is if you notice something we're going to discuss later, if you notice 05:38.960 --> 05:45.740 when we rotate the hands, follow the waist as it's rotating around, well, let's say there's, you 05:45.740 --> 05:52.370 know, maybe a table over here that I want to place his hand on or box or something. 05:52.370 --> 05:53.750 So let's just say there's a box here. 05:54.110 --> 05:58.160 So let's say I bent him over here and I want him to lean on it. 05:58.310 --> 05:58.730 All right. 05:58.730 --> 06:04.130 So let's get his hand up here and you can see how the waiting isn't necessarily great. 06:04.130 --> 06:06.020 It's it's flattening out his hand. 06:07.430 --> 06:08.420 Really weird way. 06:09.350 --> 06:15.650 So, yeah, this is not ideal, but basically what I'm getting at is so let's say we want to have him 06:15.650 --> 06:16.630 to lean on this. 06:16.640 --> 06:17.090 All right. 06:17.450 --> 06:23.240 Let's say let's let's get him to bend his elbow a little bit so we'll make him lean more as we lean 06:23.240 --> 06:23.570 him. 06:23.840 --> 06:27.470 The hand is following his body and it's not sticking to the box. 06:27.890 --> 06:34.610 So later in these later lessons, we're going to discuss having different spaces which are basically 06:34.610 --> 06:37.340 saying, what is this going to follow? 06:37.340 --> 06:39.020 What does this control going to follow? 06:39.020 --> 06:43.220 Right now, it's following the rotation of the chest and the hips here. 06:43.520 --> 06:46.220 But what if we want it to stay here and be in. 06:46.330 --> 06:53.980 WorldSpace might be relative to the world, not relative to himself, so we'll discuss that later as 06:53.980 --> 06:55.180 well, how we can do that. 06:56.050 --> 07:02.110 But that's a quick introduction on to kind of what we're seeing is why it's important and also the reason 07:02.110 --> 07:03.990 why we're going to need to make our own rig. 07:04.240 --> 07:10.720 But if you want to just quickly get into Miah and look at how to rig something, definitely check out 07:10.720 --> 07:11.620 the quick rig tool. 07:11.830 --> 07:15.310 There's also a step by step process, which we'll do in the next lesson. 07:15.340 --> 07:16.030 Thanks for watching.
