WEBVTT 00:00.210 --> 00:06.600 Welcome to this lesson where we will discuss rigging props and I really encourage you to open up the 00:06.600 --> 00:13.820 scene, follow and follow along, either with this video or right after watching the video on your own, 00:13.830 --> 00:19.560 because to learn this stuff, you really need to do it and definitely encourage you to follow along 00:19.560 --> 00:20.840 with the scene follows up included. 00:21.330 --> 00:28.190 So what we have is a hat and it actually looks better than what it seems like in the viewport. 00:28.200 --> 00:31.770 I've actually added shaders and everything so that we can use this later. 00:32.070 --> 00:41.340 And if actually unhide the sky that we have here, we can see that there's these little gemstones and 00:41.340 --> 00:45.750 it has this kind of felt texture and it looks kind of cool. 00:45.750 --> 00:46.500 I think so. 00:46.500 --> 00:52.030 Anyway, just so you don't think you're rigging something that's not going to be useful later. 00:52.050 --> 00:59.070 This already is ready to go for animation and has all the shaders and everything that I've created that 00:59.070 --> 01:07.020 is basically using a little more complicated network of shading than I discussed in the previous part 01:07.020 --> 01:07.860 of development. 01:07.860 --> 01:11.130 But you can definitely open this up and take a look. 01:11.130 --> 01:14.760 And I appreciate to deconstruct how I made that shader. 01:15.180 --> 01:17.480 So anyway, let's get on to rigging this thing. 01:18.180 --> 01:24.930 So when we think about rigging props, we need to think about how it's going to be used and namely, 01:24.930 --> 01:29.790 this is going to be on someone's head, probably, but it might also be grabbed and they might hold 01:29.790 --> 01:30.540 it in their hand. 01:31.200 --> 01:34.710 It might need to be on the table, all these different types of scenarios. 01:35.010 --> 01:43.020 So, again, we don't want to just leave this as it is right here and start setting keyframes on this 01:43.020 --> 01:44.250 geometry as it is. 01:44.490 --> 01:50.010 We want to add control curves to this as well, but we need to take into account the fact that there 01:50.010 --> 01:51.270 might be different pivot points. 01:51.570 --> 01:51.930 Right. 01:51.930 --> 01:54.390 So if this is on their head, yeah, sure. 01:54.390 --> 01:56.280 This pivot point in the center might be good. 01:56.580 --> 02:00.280 But if we hold down D and we move the pivot over here now might be best. 02:00.300 --> 02:05.370 You know, let's say he's picking it up from the side and he's going to throw it over his head or something, 02:06.240 --> 02:12.900 or maybe he's picking up from this side and needs to pivot off of a table so that this end stays on 02:12.900 --> 02:15.780 the table longer, all those types of things. 02:15.790 --> 02:19.320 So how do we address different pivots like that? 02:19.590 --> 02:26.070 Well, there's one easy way that we can create a hierarchy of controls, that we can adjust that a little 02:26.070 --> 02:27.300 bit during animation. 02:27.990 --> 02:30.060 So let's first take a look at how this was created. 02:30.360 --> 02:34.860 We have the geometry and then underneath that we have the gem's and the ribbon. 02:35.370 --> 02:43.410 So when we have this in the outliner, this type of hierarchy, this means that these pieces are children 02:43.440 --> 02:44.190 of this. 02:44.190 --> 02:44.580 Right. 02:45.120 --> 02:50.190 So if I if I click these two things and I hit shift P, that will unpack them. 02:50.350 --> 02:53.010 OK, so now it's no longer in the hierarchy. 02:53.010 --> 02:56.760 So if I move this, they don't follow around, so follow the hat. 02:56.760 --> 03:03.480 So what I need to do is either I can minimize, drag them under the hat or I can select, let's say 03:03.480 --> 03:07.800 I can do it from the viewport or the outline or I can select one and then select the other and hit P. 03:08.190 --> 03:09.300 That'll do the same thing. 03:09.330 --> 03:11.040 OK, so there's two different ways to do that. 03:11.580 --> 03:17.160 And the gyms are kind of special because they are in a group and they're in a group because there's 03:17.160 --> 03:22.380 just so many of them and it just helps to keep them organized and you can move them by themselves or 03:22.380 --> 03:25.920 find you to just where they were around the hat. 03:25.920 --> 03:27.330 That's pretty easy to do as well. 03:27.780 --> 03:29.160 And how to group things. 03:29.160 --> 03:32.280 Let's just say again, these are all by themselves. 03:32.280 --> 03:36.660 I'm going to shift up and how do we get them back the way they were? 03:37.080 --> 03:44.310 Well, we can shift select all of them and then we can hit command to group them and then I can rename 03:44.310 --> 03:47.130 that and then middle mouse drag this under the hat. 03:48.120 --> 03:53.580 So that's basically what I've already done to create this type of hierarchy that we see in the hat. 03:53.820 --> 03:56.130 But this isn't useful for actual animation. 03:56.130 --> 03:58.770 This is just kind of organizing the model so it can be rigged. 03:59.280 --> 04:01.560 So let's take a look at this. 04:02.190 --> 04:07.380 So let's create our first curve control so that we can actually use that to animate with. 04:07.620 --> 04:09.180 I'm going to go over to curves and surfaces. 04:09.180 --> 04:10.470 I'm going to click the circle here. 04:10.770 --> 04:13.260 I'm going to expand that out so that we can actually see it. 04:13.740 --> 04:17.100 And typically, you want your curves to be outside of the piece of geometry. 04:17.100 --> 04:20.250 So it's easy to select someone to expand it. 04:20.250 --> 04:22.110 So it's outside the geometry. 04:22.650 --> 04:31.140 And then I can just parent the hat underneath this inner circle, which I can call hat control. 04:32.940 --> 04:38.730 The only thing that I don't like with this is that this selection highlighting is always on right. 04:38.730 --> 04:41.190 If you use parenting, the selection highlighting is on. 04:41.190 --> 04:46.020 So every time I select this, it's going to be all these green wire frames and it's going to be difficult 04:46.020 --> 04:46.740 to see the model. 04:47.700 --> 04:54.300 So what I like to do instead and what is a little cleaner workflow is to use constraints and constraints 04:54.300 --> 04:56.850 are a very important concept to learn. 04:57.240 --> 04:58.920 And we. 04:59.190 --> 04:59.610 So we've. 04:59.820 --> 05:06.590 And kind of a one idea of a constraint, which is parenting, but there's also parent constraints, 05:07.050 --> 05:10.610 so we need to differentiate these in our mind. 05:10.860 --> 05:15.630 So let's go to animation tab and we can see there's a menu button here that says Constrain. 05:15.940 --> 05:19.230 I'm going to tear this off so we have different options here. 05:19.230 --> 05:23.910 We have parent point, orient scale, aim, all these different ones, and we'll go through them later. 05:23.910 --> 05:29.100 But right now we're just concerned with parent and parent means both point and orient. 05:29.100 --> 05:30.900 Point just means translation. 05:30.900 --> 05:37.290 That means moving it, moving this thing around in space or that whatever moving is something in space. 05:37.590 --> 05:40.200 Oriente is rotation or it means this. 05:40.250 --> 05:44.010 OK, so parent is both of these in one button. 05:44.520 --> 05:48.690 So sometimes you might want to isolate and just have one or the other, but parent is both of them. 05:48.930 --> 05:59.100 So if you remember when we parent something, we select the child first and then the parent and then 05:59.100 --> 06:03.810 we hit P, OK, that's the order in which we select things. 06:04.260 --> 06:06.780 When we do a parent constrain, it's the opposite. 06:06.780 --> 06:12.270 We select the parent first and then the child and then we click a parent. 06:13.290 --> 06:20.460 OK, rewind that and listen to that again, because that is going to be very important and you just 06:20.460 --> 06:24.900 need to commit that to memory because that that's the main difference there. 06:25.170 --> 06:27.390 That's the main point that you want to take away from this. 06:28.050 --> 06:36.300 So now that when we select this hat, control the selection, highlighting isn't on, it doesn't look 06:36.300 --> 06:37.500 like we have the hat selected. 06:37.510 --> 06:39.870 So if we try to move this, what do you know? 06:39.870 --> 06:45.840 It actually moves because if we scroll down the hat from the outliner, you can see there's actually 06:45.840 --> 06:46.950 this parent constraint. 06:46.950 --> 06:50.040 There's a new item in the outliner and it's called the parent constraint. 06:50.040 --> 06:51.870 So we can identify what it is pretty easily. 06:52.410 --> 06:58.170 In the next lesson, we're going to add a little feature to this simple rigt so it'll be easy to control 06:58.170 --> 06:58.620 the pivot. 06:58.740 --> 06:59.460 Thanks for watching.
