WEBVTT 00:00.240 --> 00:06.420 In this lesson, we're going to create the head space and I'm going to explain why that's important, 00:06.420 --> 00:11.940 because similar to similar to the shoulder set up that we created, we're going to create a set up like 00:11.940 --> 00:12.670 that for the head. 00:13.110 --> 00:19.260 So if we look at the controller I made between the previous lessons, I just continue the same methodology 00:19.260 --> 00:20.280 that we use on the spine. 00:20.580 --> 00:23.820 And I've created a net control here and it rotates the neck. 00:24.090 --> 00:26.910 But we need to make sure that it is parented to the spine. 00:26.910 --> 00:30.060 Otherwise, let's just turn off the polygon so you can see the joints. 00:32.200 --> 00:40.090 It's not following the spine, so we need to parent this to the spine, but if we did that for the head, 00:40.090 --> 00:45.580 which I created a con here, and I moved the control vertices up above the head and the skull. 00:45.580 --> 00:46.870 So it's easy to select. 00:47.410 --> 00:52.110 And I've placed the pivot right at the joint center here. 00:52.570 --> 01:00.520 So if we were to parent the head to the neck like we've done with the rest of the spine, then the rotation 01:00.520 --> 01:03.240 of the head would be dictated by that because it's a child. 01:03.250 --> 01:08.710 So if we bent the spine over, the character would be looking at the ground. 01:10.230 --> 01:12.700 But we didn't rotate the head to be looking at the ground. 01:12.720 --> 01:14.850 What if we want to keep the head rotated up? 01:16.350 --> 01:18.660 So to do that, we need to create a space for this. 01:19.200 --> 01:21.000 So and we can't use parenting. 01:21.220 --> 01:22.800 OK, we need to use constraints. 01:23.250 --> 01:32.970 So it's on parent this with shift P, and let's constrain the head here to a point up here. 01:32.970 --> 01:36.840 So we wanted to always follow, kind of like the shoulder. 01:37.080 --> 01:43.680 If we were to point constrained to this, it wouldn't matter because the point itself is never moving. 01:43.920 --> 01:48.810 We're rotating the neck and it's actually the point above it, the joint here that's moving. 01:49.110 --> 01:53.490 So let's create another locator like we've done with the shoulders and let's vertically snap it here 01:53.490 --> 01:56.280 to the neck or really the top of the head. 01:56.280 --> 02:03.360 Join here and we can just call that the head locator constrain. 02:04.470 --> 02:11.040 And it's apparent that to the neck hitting up and we can point constrain that because we do know that 02:11.040 --> 02:16.950 we always want the head itself to follow this point, but we don't want the head. 02:16.950 --> 02:19.950 Conaghan again, we don't want that to have all the constraints. 02:20.220 --> 02:21.630 So we need to create a group for it. 02:21.990 --> 02:28.410 So we'll hit Command G and we will get the center pivot up here by holding down D and V in middle mouse 02:28.410 --> 02:28.860 dragging. 02:29.070 --> 02:39.900 And we'll just call that the head con group and we're going to constrain the head coaching group with 02:39.900 --> 02:41.490 a point constraint to this locator. 02:41.850 --> 02:45.610 So it's like the locator, then the head can group and go constrain point. 02:46.140 --> 02:49.830 So now when we rotate the neck, there should follow along. 02:49.830 --> 02:53.760 But you can notice that the head itself is keeping its upright orientation. 02:54.270 --> 02:54.720 Same thing. 02:54.720 --> 03:00.960 If we rotate the spine all the way down to the head itself is going to be pointed upwards. 03:01.200 --> 03:05.640 You can see it's it's like a serving tray, like someone, a waiter coming to a table. 03:05.640 --> 03:10.950 They don't want to spill everything out when they bend over and set it on your table, they want to 03:10.950 --> 03:13.200 keep the tray upright. 03:13.530 --> 03:16.410 So that's a way to think of this and why that's important. 03:17.250 --> 03:25.110 So now let's create a space so that if we choose to have it to be that way, that the rotation of the 03:25.110 --> 03:27.600 head follows the spine, we have that option. 03:27.990 --> 03:30.870 So let's create a new attribute here. 03:30.870 --> 03:34.080 We'll go to add attribute with the Khan selected. 03:34.080 --> 03:35.550 We'll call this a follow as well. 03:35.970 --> 03:40.140 And it'll be an enum and we'll say body or world. 03:41.730 --> 03:46.590 So we'll add those two in and it's OK. 03:47.130 --> 03:51.270 And currently we're on world because it's staying upright. 03:51.270 --> 03:52.380 It's not following the body. 03:52.380 --> 03:53.910 The orientation isn't pulling the body. 03:54.210 --> 03:59.310 So let's choose world and then let's select the attribute here so that we can actually select, said 03:59.310 --> 03:59.790 Dervin Key. 03:59.790 --> 04:04.080 You have to have an attribute selected to be able to set the set driven key. 04:04.470 --> 04:11.610 Let's load that in is the driver at follow and then we need to create a constraint and orien constrain 04:11.880 --> 04:12.900 to this locator. 04:13.170 --> 04:15.810 So select the locator then go to the had gone. 04:16.170 --> 04:18.060 You go constrain Orient. 04:19.150 --> 04:23.340 So now what happens is it should follow the. 04:24.330 --> 04:30.120 Rotation of the spine, and that's what's happening, cool, so now that we have that. 04:31.250 --> 04:38.330 The head con is actually following the body, so let's change that back to body, let's select the constraint 04:38.330 --> 04:44.240 over here and it's the warning constraint that we just made and let's load that in as the driver. 04:44.430 --> 04:48.080 Select the head locator constraint over here and let's set a key. 04:49.350 --> 04:55.800 Now let's go back to the headline, let's switch this back to world, we want to get to the actual con 04:55.800 --> 04:58.530 itself, not the group select world. 04:58.530 --> 05:03.570 And then let's select the warrant constraint again so we can set that to zero. 05:04.160 --> 05:07.190 Basically turn that off and let's set a key there. 05:07.740 --> 05:11.760 So now it should be back to following the WorldSpace and staying upright. 05:12.510 --> 05:17.700 But if we want to switch it out now, we have it on this control itself and we don't have to go hunting 05:17.700 --> 05:21.360 inside the outliner for the constraints. 05:22.530 --> 05:27.390 So now all we have to do is just to parent this into the con group here. 05:27.840 --> 05:31.220 So I'm going to minimize drag that into the con group. 05:32.010 --> 05:34.800 And again, let's just double check that everything's working. 05:34.800 --> 05:40.620 Every time we do something, we need to make sure that scale and move and everything is still working. 05:41.280 --> 05:42.510 That appears to be the case. 05:42.960 --> 05:49.540 So I'll see the next lesson where we will begin to parent and scan the actual geometry to the rig. 05:49.590 --> 05:50.310 Thanks for watching.
