WEBVTT 00:00.750 --> 00:06.450 In this lesson, we're going to continue to add different spaces for the hands to follow, so currently 00:06.450 --> 00:09.990 we have it to follow the shoulder, which is going to be kind of the default setting. 00:10.290 --> 00:17.840 And let's add one so that when we rotate the spine, the arms will follow the spine rotation. 00:17.850 --> 00:22.980 So when we go back and forth, the arms would kind of swing around and they wouldn't be stuck going 00:22.980 --> 00:25.100 in in the same direction that they are here. 00:25.680 --> 00:31.590 So let's get to the locators first and let's just hide those for cleanliness. 00:32.010 --> 00:36.000 So I'll just go control H to hide those since we don't really need those. 00:36.450 --> 00:41.400 And if we ever want to get back to them, we can just frame up the left shoulder icon and scroll that 00:41.400 --> 00:43.890 down and see those locators right there. 00:44.130 --> 00:48.840 So what we want to do is add a constraint to this same group. 00:50.170 --> 00:58.680 So let's call it down and let's select the top spine joint first and then let's go to the left hand 00:58.680 --> 01:01.080 group and create a new constraint. 01:01.810 --> 01:03.660 So go to parent constraint. 01:04.440 --> 01:10.140 And if you can tell, we actually have this point constraint here and now we have a parent constrained 01:10.140 --> 01:10.440 node. 01:10.440 --> 01:14.180 So we have to we have this one and we have that one, OK? 01:14.400 --> 01:17.900 And they're both activated on the group itself. 01:17.910 --> 01:22.040 We have this kind of blended parent going on and we can just ignore that for now. 01:22.500 --> 01:25.230 So let's take a look and see what happens when we rotate this. 01:25.230 --> 01:29.580 Now, we can see it does indeed follow the spine. 01:29.670 --> 01:30.450 So it's pretty good. 01:30.930 --> 01:35.430 If we rotate the shoulder, we can see that it does not work. 01:36.300 --> 01:37.140 So that's no good. 01:38.130 --> 01:42.720 So we want to make sure that they're both working in conjunction with each other. 01:43.020 --> 01:46.560 So we're going to need to add another group above this hand. 01:46.990 --> 01:50.530 So let's undo that so that we get rid of that constrain. 01:50.850 --> 01:51.420 OK, great. 01:51.430 --> 01:55.020 So let's add another group above this. 01:55.410 --> 01:57.540 So I'm just going to type in group again. 01:58.560 --> 02:06.630 So I'll be in the same spot and it looks like it's trying to go half and half between maybe something 02:06.630 --> 02:07.590 that was in the group. 02:08.270 --> 02:09.770 I was probably the constraint. 02:10.230 --> 02:19.050 So when you type in group, it's trying to find the center pivot of whatever you have selected. 02:19.050 --> 02:25.560 And because the constraint is just needs to be said that it's somewhere in the world and that's a zero 02:25.560 --> 02:25.830 zero. 02:25.830 --> 02:30.180 It's going to the group that we just made is kind of trying to split the difference. 02:30.600 --> 02:35.640 So we can just hold on DSV and just snap that back to the hand. 02:35.930 --> 02:40.440 Doesn't really matter, but it's just kind of nice to have everything, you know, around about where 02:40.440 --> 02:41.040 it should be. 02:41.580 --> 02:45.960 So let's just say left and 02:48.210 --> 02:50.550 just group. 02:53.110 --> 02:58.840 And let's make the constraint on this group, so let's go to the spine joint, select the left hand 02:58.840 --> 03:01.080 chest and we'll go to constrain parent. 03:01.540 --> 03:04.560 So again, we select this con. 03:05.470 --> 03:07.360 It should rotate around just fine. 03:07.360 --> 03:11.080 And of course, now the pull back pull vectors kind of following a little bit. 03:11.710 --> 03:14.530 Just because we did a point constrain, it's not going to rotate around. 03:14.530 --> 03:17.980 But anyway, that's you know, you have you have tradeoffs. 03:17.980 --> 03:20.450 You have to pick your battles on on functionality here. 03:20.800 --> 03:23.950 So now when we use this, it should still follow. 03:24.250 --> 03:29.620 So that's why we need to hierarchy's here in the left hand grip so we can have separate the constraints 03:29.620 --> 03:31.390 out and to do two different groups. 03:31.930 --> 03:39.040 So the one thing that we need to do is add a follow group here on the card so it's easy to control what 03:39.040 --> 03:39.700 it's following. 03:40.000 --> 03:47.800 So let's go to the channel box here and we'll go edit and we'll say add attribute and we'll go to a 03:47.800 --> 03:48.370 enum. 03:49.210 --> 03:58.180 And instead of these colors here, we can type in whatever we want and let's just say shoulder and then 03:58.180 --> 03:59.680 let's say chest. 04:02.040 --> 04:08.850 And let's add another one, just click anywhere in here and then we can say world cool. 04:09.000 --> 04:15.630 So let's add a name up here and we'll just say follow and let's add. 04:18.180 --> 04:25.830 So now we have this kind of follow item over here and we need to add a set driven key to this so that 04:25.830 --> 04:30.160 from this controller we can control which constraints are being activated. 04:30.690 --> 04:33.480 So right now, let's figure out what we have. 04:33.480 --> 04:36.740 We have the we're following the chest and the shoulder. 04:37.050 --> 04:41.870 So any time that we're following the chest, I think we also need to be following the shoulder. 04:42.210 --> 04:45.690 So those would work together, OK, that the shoulder would always be on. 04:45.690 --> 04:48.150 If the chest is on, it's not one or the other. 04:48.330 --> 04:49.710 They would always be on together. 04:50.040 --> 04:54.080 So let's just call this the chest follow. 04:54.540 --> 04:55.590 So we'll go to chest. 04:56.820 --> 05:01.860 We will go to edit set driven key like we've done before, and we'll load the driver. 05:02.050 --> 05:06.540 We'll go down to follow and then let's select the constraints. 05:08.160 --> 05:14.520 So I'll go to this constraint first and load driven and let's go down to the Ashry that actually controls 05:14.520 --> 05:19.730 the constraint here, we can see that it's set at 1:00, so we know it's on. 05:20.280 --> 05:21.690 So let's keep that. 05:22.560 --> 05:29.670 Now we can see this little set driven key keyframe pop up, then let's go down to the chest, constrain, 05:30.070 --> 05:33.490 load that as a driven and go down to the spine three. 05:33.720 --> 05:41.100 This is one advantage of naming everything, as we can very clearly see where the constraint is on this 05:41.100 --> 05:41.720 attribute. 05:42.210 --> 05:44.060 So let's keep that as well. 05:44.070 --> 05:45.230 We can see that pop up here. 05:45.240 --> 05:46.080 We know it's keyed. 05:46.530 --> 05:53.580 So we now know that with this controller, the follow chest is as it should be. 05:53.750 --> 06:00.840 OK, so let's go to the shoulder now and we're going to want to turn off the chest. 06:01.320 --> 06:02.700 So let's select the chest. 06:03.760 --> 06:07.710 Let's go to that and hit zero and keep that. 06:08.940 --> 06:12.180 Now let's go to the shoulder and we'll load the driven. 06:12.960 --> 06:18.270 Go back to that attribute here and we'll leave that on one and it keep cool. 06:18.280 --> 06:20.130 Now, you have two different options. 06:20.130 --> 06:25.440 Now we have the shoulder, so the spine shouldn't affect it, following or not. 06:25.710 --> 06:26.670 And that's the case. 06:26.670 --> 06:31.410 But it is still following the shoulder here, which is what we want. 06:32.250 --> 06:34.680 So now we have this kind of nice control. 06:34.710 --> 06:39.930 We can go back and forth without having to go deep into the rig and figure out where the constraints 06:39.930 --> 06:40.110 aren't. 06:40.110 --> 06:40.710 All that stuff. 06:40.980 --> 06:44.360 It lives right here on the con where we want it to be. 06:44.640 --> 06:46.920 So let's do the final one of the world space. 06:46.920 --> 06:55.590 Let's switch this to world and then let's go to the driven and let's turn off the point constraint of 06:55.620 --> 06:56.310 the shoulder here. 06:56.670 --> 07:00.750 So we'll go to zero and let's keep that. 07:02.010 --> 07:07.350 And just for good measure, even though this one is already off, let's just lower as a driven and keep 07:07.350 --> 07:10.800 that as off as well. 07:11.310 --> 07:13.230 It should already be off. 07:13.230 --> 07:15.270 I'm not sure why it's not. 07:16.290 --> 07:26.640 It's a little suspicious that to zero and a key and so the hand should now stay where it is and that's 07:26.640 --> 07:27.400 what it's doing. 07:27.420 --> 07:27.790 Cool. 07:28.350 --> 07:34.950 So now we have a controller that we can affect the different space that we want it to be in. 07:35.400 --> 07:40.440 And the only thing to keep in mind is if we start to animate this, it's probably going to jump around. 07:40.740 --> 07:47.850 So we just need to typically, you know, stick with one just to make our lives a little easier when 07:47.850 --> 07:48.600 we're animating. 07:48.600 --> 07:53.580 So I'm going to do this to the other side and then I'll see you in the next lesson where we will continue 07:53.580 --> 07:55.050 to finish out this rig. 07:55.140 --> 07:55.830 Thanks for watching.
