WEBVTT 00:00.330 --> 00:04.630 In this lesson, we're going to learn about reverse foot rigs and why that's important. 00:05.070 --> 00:08.940 So if we take a look at the foot down here and we click the icon handle and start moving it around, 00:09.210 --> 00:11.760 we can see that the foot just kind of does whatever it's going to do. 00:12.360 --> 00:16.710 Partly that's because the pull factors here are still at the knee. 00:16.980 --> 00:23.850 But even when we pull those out, you can see that the foot tries to stay pointed downward and then 00:23.850 --> 00:28.500 we would have to maybe do something like this and and rotate the joint individually. 00:28.950 --> 00:35.130 But if we think about how a foot moves, it does a heel to toe action. 00:35.130 --> 00:39.520 So it pivots from the heel and then pivots off of the ball and then the toe. 00:39.840 --> 00:42.960 So we need to create that type of a rig in our skeleton as well. 00:43.200 --> 00:45.890 So to do that, we're going to create what's called a reverse foot rig. 00:46.050 --> 00:47.880 And there's several different ways we can do this. 00:48.120 --> 00:49.740 Well, this is just the way that I like to do it. 00:50.010 --> 00:54.000 So I'm going to go to the rigging tab here and get to the joints. 00:54.340 --> 00:57.360 I'm going to go into the right view so we can get a look at the foot. 00:57.570 --> 01:01.770 So now that we're in the side view, we need to enable the view of the polygons because this rig is 01:01.770 --> 01:05.170 going to be based off of the shape of the polygons and the foot. 01:05.190 --> 01:09.990 So we need to create a joint basically where the heel is going to pivot from back here. 01:10.500 --> 01:15.630 And we need to go all the way to the toe and then we need to go all the way to the ball, the foot and 01:15.630 --> 01:16.260 the back up. 01:16.290 --> 01:21.990 So we basically made a reverse joint chain of what we already kind of had built. 01:22.410 --> 01:28.320 And the only thing we need left to do is to actually get this in place because we made this in the kind 01:28.320 --> 01:30.210 of world position there. 01:30.660 --> 01:37.730 So let's get that there and let's vertex snap these to the joints that are they are near. 01:38.250 --> 01:40.070 So I'm going to select this one. 01:40.080 --> 01:45.140 Hold down D and V and middle mouse, drag it to the joint when it's like this. 01:45.150 --> 01:51.210 But I want to do the same thing all down D and V middle mouse drag and get it to the joint and just 01:51.210 --> 01:54.000 make sure it actually went to the center there and it did. 01:54.420 --> 01:59.820 And turn off the show polygons real quick while I'm doing this to make sure I'm not vertex snapping 01:59.820 --> 02:05.570 to the geometry when a vertex snapped the center of these joints so holding down and V Vertex snapped 02:05.570 --> 02:05.850 that. 02:06.360 --> 02:12.660 So now what we have is a little joint chain that is going to behave the way that I described. 02:12.660 --> 02:14.670 We have a heel pivot here, right? 02:15.300 --> 02:16.680 We have a toe pivot. 02:18.600 --> 02:25.770 And we have a ball joint pivot cool, so now all we have to do is rename this and rig it up to work 02:25.770 --> 02:26.400 with the foot. 02:27.060 --> 02:31.050 So I'm going to rename this and I'll see you in one second. 02:39.670 --> 02:45.070 So now that we have that renamed, let's smear this over very quickly with the mere tool go skeleton 02:45.070 --> 02:51.370 mirror and we have all the things properly labeled so that it's going to be named the right thing over 02:51.370 --> 02:51.680 here. 02:52.150 --> 02:52.450 Cool. 02:53.320 --> 02:53.570 Great. 02:53.590 --> 02:55.540 So now we have a foot rig built. 02:55.540 --> 02:58.710 We have the original and we have the reverse foot rig. 02:58.930 --> 03:01.660 Let's make the reverse foot rig display a little bigger. 03:01.660 --> 03:04.860 So I'll select the hierarchy of it and go to the radius and increase that. 03:04.870 --> 03:09.700 So now visually, we can tell the difference between the reverse foot rig and the original foot joint 03:09.700 --> 03:13.690 chain here because we want the eye can handle to follow this reverse foot rig. 03:14.080 --> 03:18.160 So let's make that happen to the top joint, because if we if you think about it. 03:18.460 --> 03:18.880 Sure. 03:18.880 --> 03:24.700 If we were to, you know, point constrain this to this heel bone, then it would follow along like 03:24.700 --> 03:25.030 this. 03:25.030 --> 03:31.990 But when we move to rotate the toe, it would stay behind because it's just following the rotation and 03:31.990 --> 03:33.000 position of this. 03:33.010 --> 03:37.210 So we want to constrain it to this end joint because we want it to be up here. 03:37.220 --> 03:39.220 We want the I can handle to follow this one. 03:39.220 --> 03:39.610 Right. 03:40.150 --> 03:47.000 So I do that and let's select that in joint and then the IC handle and then go to constrain point constrain. 03:47.440 --> 03:52.210 Now when we select the reverse foot rig and we move it around, you can see that it does follow. 03:52.360 --> 03:56.460 And if we move and rotate the toe joint here, it should follow as well. 03:56.680 --> 03:59.890 And you should do this every time that you make a constrain, you want to test that. 03:59.890 --> 04:02.030 It's working it in the way that you would expect it to. 04:02.410 --> 04:08.800 So everything is except for the original foot chain here, which you can see here that is not following 04:08.800 --> 04:09.350 along anywhere. 04:09.370 --> 04:11.100 So we need to do that next. 04:11.530 --> 04:19.000 So let's select the end joint here and let's orient constrain these original foot bones to the reverse 04:19.000 --> 04:21.250 foot rig of the joint in front of it. 04:21.610 --> 04:25.420 So the bone in front of this one that it should follow is the toe. 04:25.630 --> 04:29.650 So it's like the toe and then the original and go to constrain Orient. 04:30.140 --> 04:35.470 Let's do the same thing here, which is like the ball and then select the original and you go constrain 04:35.470 --> 04:35.940 Orient. 04:36.430 --> 04:39.760 So now we have the same behavior that we had before. 04:39.760 --> 04:43.720 Everything follows, except now the original foot rig follows the reverse foot rig. 04:44.140 --> 04:45.700 So that's exactly what we want. 04:45.730 --> 04:50.940 So if we were to to make the toe go up and pivot from the toe, the entire foot rig will follow. 04:50.960 --> 04:56.660 Same thing if we pivot from the ball of the foot, the ankle and everything will follow as well. 04:57.040 --> 04:57.360 Great. 04:57.370 --> 05:03.430 So in the next lesson, I will create a control for this and show you how to do set driven keys to drive 05:03.430 --> 05:07.420 this foot control from one attribute and the ashmead ed over here. 05:07.720 --> 05:11.200 So go ahead and create the same foot rig for the right as well. 05:11.470 --> 05:16.810 And the next lesson will create the nerves control curve here to control the foot. 05:17.050 --> 05:17.740 Thanks for watching.
