WEBVTT 00:00.150 --> 00:05.280 In this lesson, we're going to fix an issue that we have when we move the shoulders here with the hand, 00:05.290 --> 00:10.290 so we rotate the shoulders up, we can see their shoulders are moving as we expect them to, but that 00:10.290 --> 00:11.640 is just kind of stretching the hand. 00:11.640 --> 00:12.950 The hand's not moving with it. 00:13.290 --> 00:16.860 We would expect it to move at least in this direction. 00:16.860 --> 00:17.110 Right. 00:17.130 --> 00:19.890 We would want the hand to go with that and go over here. 00:20.160 --> 00:21.750 Maybe not rotate up with the arm. 00:21.750 --> 00:26.760 That'd be something different, but just at least be drawn inward when this is rotated up. 00:27.060 --> 00:33.150 So to do that, we need to point constrain the group of this, the left hand group that's remember why 00:33.150 --> 00:36.260 we're always creating into groups above controllers. 00:36.270 --> 00:43.530 As for this exact reason, and just as an example, let's just say we constrain that real quick. 00:43.950 --> 00:47.400 The problem with that is if we rotate this, it's going to go all the way with it. 00:47.730 --> 00:53.520 And that's going to be a big problem in animation if we just want to make small adjustments in the shoulder 00:53.730 --> 00:59.630 and then the hand is going crazy and following it from this large of a distance and rotating like that. 00:59.640 --> 01:05.790 So that's not really when you think about how you're going to be animating it, you have to build your 01:05.790 --> 01:07.020 legs based around that. 01:07.290 --> 01:10.260 So I just want to show you why we're not going to do a parent constraint. 01:10.650 --> 01:15.660 So if we did a plane constrained with this, that actually wouldn't do anything because and we can try 01:15.660 --> 01:17.990 that real quick just to show you, you know, it doesn't do anything. 01:18.390 --> 01:21.360 So if we do a point constrain, it doesn't do anything. 01:21.360 --> 01:24.480 Because if you think about what's happening, we're just changing rotation values. 01:24.480 --> 01:26.310 Point constraint is all about translation. 01:26.670 --> 01:28.710 And this is pivoting from over here. 01:28.710 --> 01:31.340 The point itself is not moving anywhere. 01:31.350 --> 01:32.580 If we moved it, it would go. 01:32.940 --> 01:36.150 But we're going to mostly be rotating the shoulders. 01:36.150 --> 01:41.790 And so we want to pick a point that's right here for the hand to follow. 01:41.790 --> 01:43.340 So we need to create that ourselves. 01:43.890 --> 01:45.330 So let's undo all this. 01:45.750 --> 02:00.570 Let's create a locator and call it the left shoulder point, constrain something, you know, that makes 02:00.570 --> 02:00.900 sense. 02:01.860 --> 02:02.790 Now it's vertical. 02:02.790 --> 02:08.040 SNAP that to this pivot point, this kind of part of the shoulder, and we're going to parent it to 02:08.040 --> 02:09.680 this con someone happy. 02:10.140 --> 02:16.080 So now when we rotate this, we have a point that we can use to add a point constraint to to from this 02:16.080 --> 02:16.380 hand. 02:16.770 --> 02:19.020 So let's select that locator. 02:19.410 --> 02:24.290 And I'm just going to copy that for now so we can duplicate that here in a second. 02:24.570 --> 02:30.330 So I'm going to select the locator that I'm going to command, select the group and choose point constrain. 02:30.620 --> 02:32.820 Now, when we do it, check it out. 02:33.420 --> 02:40.120 The hand kind of floats and keeps the orientation it had with the arm, but it will follow the shoulder. 02:40.160 --> 02:41.190 Now, that's pretty cool. 02:41.600 --> 02:46.860 So let's do that with the other side and I'll see the next lesson where we will add another level of 02:46.980 --> 02:50.750 constraint to the hand where we can get it back to world if we wanted to. 02:51.090 --> 02:52.120 I'll see in the next lesson. 02:52.140 --> 02:52.800 Thanks for watching.
