WEBVTT 00:00.240 --> 00:05.960 In this lesson, we're going to create the controls for the hands and the feet and we're going to just 00:05.970 --> 00:08.100 only get partially done with the feet. 00:08.100 --> 00:13.350 And we'll follow up on the next lesson about how to properly create all the controls on the feet. 00:13.380 --> 00:15.360 But let's get started on doing that now. 00:15.360 --> 00:22.710 So similarly to the last lesson, I'm actually going to unhide the polygons here so we can see this 00:22.710 --> 00:23.040 again. 00:23.610 --> 00:28.710 And I'm going to drag this over the side so we can see a little better this time and create a cube. 00:29.130 --> 00:33.120 And then I'm going to go to the curves and services like we did last time and make sure from the tool 00:33.120 --> 00:35.760 setting that we're on linear so that it's straight edges. 00:36.120 --> 00:41.850 Don't hold down V and click on each one of these corners so that we make sure that we have everything 00:41.850 --> 00:44.520 covered on the edges. 00:53.720 --> 00:56.070 Hit, enter and delete the cube. 00:56.670 --> 00:57.870 Now we have our curve, 01:00.810 --> 01:03.890 but because we moved over here to the side, the origin is over here. 01:03.900 --> 01:07.260 So I have to do is say modify center, pivot and boom. 01:07.260 --> 01:07.830 There we go. 01:08.400 --> 01:11.920 So let's show let's hide the polygons again. 01:11.920 --> 01:17.820 And of course, this show menu is just this show menu I tore off here by clicking that and let's ahai 01:17.830 --> 01:26.010 the polygons one more time so we can vertex snap with that con selected vertex snap to the hand and 01:26.040 --> 01:27.480 let's just increase the size of that. 01:27.480 --> 01:28.140 Just a touch. 01:28.440 --> 01:33.120 And then of course like we did on the pull vector, let's freeze the transformations because any time 01:33.120 --> 01:38.280 we zero this out, we want to get back to this origin point and let's call this. 01:40.890 --> 01:53.370 Left and gone, and let's duplicate it and drag it over here to the right end by hitting W and then 01:53.370 --> 01:57.660 holding V to Vertex, snap it and we'll just rename that. 01:57.660 --> 01:58.020 Right. 02:00.720 --> 02:01.100 Cool. 02:01.650 --> 02:06.510 And if you remember in a previous lesson, we're talking about having empty groups with so that we can 02:06.510 --> 02:07.620 strain these things. 02:07.890 --> 02:08.940 Let's go ahead and do that now. 02:08.940 --> 02:13.050 So I'm going to make an empty group from this hand area. 02:13.290 --> 02:17.370 But I'm also just going to, for cleanliness sake, make it at this origin. 02:17.370 --> 02:23.880 And how I do that is by typing in group here instead of hitting the shortcut command G and we do that. 02:23.880 --> 02:27.360 It actually has the pivot point in the center of the object that where we're creating it from. 02:27.660 --> 02:30.450 So I'm going to copy paste the name here. 02:30.690 --> 02:35.280 And instead of corn, I'm going to call it group and I'm going to do the same thing for this side. 02:52.240 --> 02:57.340 So that way, if we want to constrain this con to something, we'll constrain it with the group and 02:57.340 --> 03:02.380 not the con itself so that the con is still free to have animation on it and won't have the little blue 03:02.380 --> 03:04.690 boxes here that will prevent us from animating it. 03:05.300 --> 03:05.650 Great. 03:05.860 --> 03:09.030 So let's actually hook this up to the IRC controller. 03:09.310 --> 03:16.840 So let's go to the IRC left arm and let's focus on that. 03:19.210 --> 03:28.450 So let's select this object and we will command click the IC from the outliner and let's go to control. 03:28.450 --> 03:31.120 Let's go to constrain and use a point constrain. 03:31.550 --> 03:34.090 Let's just open that up to make sure we maintain Offsiders on. 03:34.360 --> 03:38.050 And even if it wasn't, it shouldn't matter because they're snap to each other. 03:38.050 --> 03:39.010 So let's it apply. 03:39.640 --> 03:44.500 And you can see that nothing looks like it happened besides the fact that I can handle now has those 03:44.500 --> 03:50.050 blue little dots, which means, of course, if we scroll this down, we can see indeed it does have 03:50.050 --> 03:50.730 a point constrained. 03:50.740 --> 03:54.550 You can also see the pull vector constraint as well there that we did in the previous lesson. 03:55.090 --> 04:02.100 So now if we move this con around, it is what is controlling the I can handle now. 04:02.320 --> 04:02.820 Perfect. 04:03.420 --> 04:05.110 So now we don't have to worry about the I can handle. 04:06.100 --> 04:11.950 But how do we control the rotation of the hand because it's not rotating with this con anymore. 04:12.370 --> 04:13.170 Well, that's pretty easy. 04:13.180 --> 04:24.370 So let's go to the icon here, the hand arm con and let's shift select the hand joint and go to constrain 04:24.370 --> 04:24.940 Orient. 04:25.720 --> 04:30.580 And with that selected, we can say maintain, offset all that's fine and apply. 04:31.180 --> 04:35.500 And I can see that there's blue dots and the rotation of the joints. 04:35.920 --> 04:44.880 So now if we move this, everything still moves, but it's locked in rotation to the con itself. 04:45.220 --> 04:51.130 So now we can actually rotate the hand as we need it and that works really well. 04:52.000 --> 04:57.610 Similarly, we want to make sure before we get too far that these rotations have the right rotation 04:57.610 --> 04:59.410 order like we talked about in a previous lesson. 04:59.410 --> 05:05.080 So let's go into the Gimel mode here by holding down E and going to Gimble left clicking there. 05:05.440 --> 05:10.570 And let's just see that it is kind of working how we would expect it to. 05:11.070 --> 05:13.750 It looks like that'll work pretty fine, actually. 05:13.930 --> 05:14.560 You know what? 05:15.280 --> 05:21.280 That won't work very well, because if we bring the hand out in front and then we rotate it to be pointing 05:21.280 --> 05:23.740 forward, we're immediately in Gimble. 05:23.740 --> 05:24.400 Check that out. 05:24.580 --> 05:26.020 We do not want that for sure. 05:26.320 --> 05:27.940 OK, so let's undo that. 05:28.250 --> 05:32.050 Get this back to Origin and let's go to the rotation order and fix this. 05:32.410 --> 05:39.340 So we need to go down to the con here, to the rotate order and let's choose this bottom one and see 05:39.340 --> 05:42.040 that that actually is not what we want either. 05:43.210 --> 05:47.410 We let's go to the so let's think about what we're doing here. 05:47.650 --> 05:54.190 We want the parent con to be y OK, so we want that to be the last letter in this order. 05:54.190 --> 05:55.420 So we want one of these two. 05:56.020 --> 05:58.390 So now we have what we need. 05:58.600 --> 05:58.990 Cool. 05:59.560 --> 06:01.900 OK, and don't forget when you do this for this side as well. 06:01.900 --> 06:06.250 So we need X, Z, Y is what we did over here. 06:06.250 --> 06:08.590 So let's do X, Y, Z, Y over here. 06:09.580 --> 06:10.000 Cool. 06:10.150 --> 06:11.920 So I hope that Gimble thing is kind of making sense. 06:11.920 --> 06:16.960 Now you can see where a controller that we're going to move around a lot everywhere in 3D space. 06:17.980 --> 06:22.240 We're gonna need to rotate it, that it's going to need to move with itself. 06:22.570 --> 06:28.120 And it looks like, as you know, let's say he just has his hands at his side. 06:28.690 --> 06:35.500 Well, it looks like this isn't the best rotation order either for that, because now we're in gimbal 06:35.620 --> 06:36.070 here. 06:36.490 --> 06:40.660 So let's choose the other rotation order that has y at the end here. 06:40.870 --> 06:42.030 It's zwi. 06:42.220 --> 06:43.780 So let's just see if that works for us. 06:44.530 --> 06:45.360 Zwi. 06:45.580 --> 06:45.900 Cool. 06:45.910 --> 06:50.620 So let's bring the hand down and this is well we have a hook that I can handle up seltzer's this one. 06:51.310 --> 06:52.600 This is part of rigging, right. 06:52.600 --> 06:56.710 Like you do something and then you test it to make sure it's going to behave the way you want it to. 06:58.420 --> 06:58.810 Cool. 06:59.530 --> 07:03.160 So yeah, I don't think we'll ever really get while we might. 07:03.160 --> 07:09.100 I mean, this is the thing with rotations is, you know, especially something that's going to move 07:09.100 --> 07:16.030 in a lot of axes at some point it may very well get into Gimble and there's only so much we can do to 07:16.030 --> 07:16.720 prevent that. 07:16.990 --> 07:19.990 So, like, there's an example of us getting into Gimble there. 07:20.650 --> 07:25.690 So you kind of have to pick your battles and where you want to address this. 07:26.470 --> 07:30.340 But I think for the most part, let's think about this. 07:30.340 --> 07:32.950 If it's down to his side, this is the most common thing. 07:33.160 --> 07:33.790 Let's do that. 07:33.790 --> 07:35.860 Let's have Zebb that be the one. 07:35.860 --> 07:36.160 All right. 07:36.160 --> 07:41.080 Let's let's rethink this here, because in reality, most people aren't going to have their hands out 07:41.080 --> 07:41.620 in front of them. 07:41.980 --> 07:44.290 And so we want Z to be the last one. 07:44.770 --> 07:46.180 So I think that works fine. 07:46.180 --> 07:49.900 And let's think about all. 07:50.060 --> 07:54.980 Because you kind of have to consider all the scenarios here in light of the most likely one. 07:55.520 --> 08:01.880 OK, so the most likely one is the hands going to be down here by his side and rotated like that? 08:02.030 --> 08:03.300 That's how most people stand. 08:04.220 --> 08:07.360 So I think that is probably going to be the right rotation order. 08:08.060 --> 08:11.360 And it took, you know, just messing with this, thinking about it, talking through it. 08:11.990 --> 08:13.880 How are we really going to use this, OK? 08:14.200 --> 08:16.790 Y Z is what we need are going to be cool. 08:17.180 --> 08:23.300 Let's go over here, Y, Z, and let's do the same constraints with this side. 08:28.870 --> 08:32.260 Great, now we like this, everything should follow along just fine. 08:35.600 --> 08:35.990 Great. 08:37.250 --> 08:44.690 So the other thing you might notice is the fact that the poll vector doesn't move, you know, at all, 08:44.750 --> 08:45.130 right? 08:45.510 --> 08:46.880 Just going to stay wherever it is. 08:47.540 --> 08:49.280 Well, there's one thing we can do with that as well. 08:49.290 --> 08:54.440 We can actually make groups for these and then constrain the groups to the hand so they kind of follow 08:54.440 --> 08:54.890 along. 08:55.310 --> 08:56.180 So let's do that now. 08:56.510 --> 08:59.390 Let's select this and type in group. 09:04.560 --> 09:06.660 And let's just copy this into the group. 09:09.290 --> 09:13.250 And do that for the other side and then end the legs. 09:19.710 --> 09:25.500 Clearly, we have that done, let's take a look at what actually will happen now, so let's constrain 09:25.500 --> 09:27.090 the group of this pull vector. 09:27.240 --> 09:32.160 So it's this one right here just going to minimize these so we can focus in on and the outliner what 09:32.160 --> 09:33.060 we're actually going to use. 09:33.620 --> 09:34.500 It's going to be this one. 09:34.500 --> 09:36.650 And this one had off here will open that up. 09:37.020 --> 09:40.810 So we want the grip of this to follow this. 09:40.830 --> 09:46.700 So let's select this first and then the group of the pull vector and say constrain parent. 09:47.850 --> 09:51.320 Now, when you move this, the ball vector should follow. 09:52.680 --> 09:56.730 But, you know, it's not ideal right now because we haven't figured this out. 09:57.150 --> 09:58.260 So let's zero this out. 09:58.260 --> 10:04.470 Now, if you remember from the last lesson why we left it here and we'll zero this out. 10:04.470 --> 10:05.370 So it's back here. 10:05.580 --> 10:07.100 So now it gives us some room. 10:07.440 --> 10:16.470 So when we do this, the pull vector should follow the hand and the arm and it will let's move this 10:16.470 --> 10:17.280 back to object. 10:18.000 --> 10:22.920 The only thing that we might want to do is use a point constraint instead of a rotation, because you 10:22.920 --> 10:26.220 can see as I rotate the hand, this thing goes pretty wild. 10:26.550 --> 10:29.160 So that's not really what we want it to be doing. 10:29.310 --> 10:31.860 We want it to just kind of be in the area. 10:31.890 --> 10:36.210 We want it to kind of generally be where we are moving the hand. 10:36.450 --> 10:38.240 So we want a point constraint instead. 10:38.580 --> 10:44.220 So let's go to the group of this which is here and delete the constrain and use a point constraint instead. 10:44.220 --> 10:52.080 So select the hand, go to the vector group command, clicking it from the outliner and go to constrain 10:52.080 --> 10:52.500 point. 10:53.220 --> 10:54.390 Let's do the same thing over here. 11:00.190 --> 11:05.000 Great, now, when I say like this and move it around, we can see that it should be moving with it. 11:05.020 --> 11:11.410 And again, if I zero these out, which should be fine now because we have constrained orientation of 11:11.410 --> 11:13.600 the hand joint to be taken. 11:13.600 --> 11:16.180 So it shouldn't really matter how far away this goes. 11:16.600 --> 11:17.350 So I zeroed out. 11:17.350 --> 11:19.660 You can see the hand stays the same, the joint stays the same. 11:20.170 --> 11:22.570 So now we can have those out where they need to be. 11:22.990 --> 11:27.730 Now, when I move this, the whole vector should kind of try to follow along a little bit. 11:28.030 --> 11:32.170 And this is just kind of something that, you know, is a preference. 11:32.470 --> 11:34.060 You might not want that to take place. 11:34.060 --> 11:36.340 You might want to be doing its own thing. 11:36.760 --> 11:42.130 But, you know, the nice thing about having these groups is the fact that the constrain lives in the 11:42.130 --> 11:42.430 group. 11:42.430 --> 11:49.780 If I press, select the controller and press up, I get to the group and I can see that these are indeed 11:49.780 --> 11:51.550 kind of locked here and the constraint. 11:51.820 --> 11:55.800 But when I select the control, I can still manipulate the control all around. 11:56.230 --> 12:02.470 So that's one way to organize this so they can kind of get some not animation for free, but just kind 12:02.470 --> 12:06.610 of like have it organized so that when you move the hand, you know, the pull vector is not trying 12:06.610 --> 12:07.660 to stay in the same spot. 12:08.560 --> 12:13.480 So in this lesson, we learned quite a bit, a lot about pull vectors and constraints and ICA's. 12:13.480 --> 12:15.400 And so I think we've done a lot. 12:15.400 --> 12:19.900 And in the next lesson, we're going to take a more in-depth look about the foot. 12:20.230 --> 12:22.960 It's actually one of the most complicated things we're going to cover in this course. 12:23.230 --> 12:28.210 So let's take an entire video to definitely cover that and why this is important. 12:28.270 --> 12:28.900 Thanks for watching.
