WEBVTT 00:00.300 --> 00:05.400 Before we begin the next exercise in learning some more principles about animation, I want to show 00:05.400 --> 00:10.270 you this rig and how to set up this scene so that it's easiest to use this rig. 00:10.530 --> 00:16.620 So if you've skipped ahead from the rigging section of this course and you haven't taken that, you 00:16.620 --> 00:18.290 will not be familiar with the rigs yet. 00:18.540 --> 00:20.340 So I want to explain this. 00:20.340 --> 00:24.360 And even if you have taken the rig and course there's a lot here to learn as well. 00:24.450 --> 00:30.060 So the first thing to consider is the fact that in the previous lessons we were animating the geometry 00:30.060 --> 00:30.750 itself. 00:31.110 --> 00:35.420 We're moving the geometry around and setting key frames on the geometry in general. 00:35.430 --> 00:37.340 You basically never want to do that. 00:37.350 --> 00:42.930 You always want to work on a control rig so that there's a hierarchy built in so that we're controlling 00:42.930 --> 00:44.970 something other than the geometry. 00:45.240 --> 00:52.080 So the geometry is clean and has no keyframes on it and that the key frames only exist on the curves 00:52.080 --> 00:52.800 themselves. 00:53.250 --> 01:00.450 Now these curves are what's called a nerve's curve and those are in this shelf and you can create your 01:00.450 --> 01:01.950 own and play around with that. 01:01.950 --> 01:04.260 But in this case, the rig is already built. 01:04.830 --> 01:09.450 You don't have to do anything for rigging for this and you just need to open the scene to use it. 01:09.810 --> 01:14.340 So one thing to consider is the fact that we don't want to be able to like the geometry like I just 01:14.340 --> 01:14.910 described. 01:14.910 --> 01:17.970 We want to only select the curves. 01:18.270 --> 01:22.080 So there's a couple of different ways you can make sure that while you're animating, you're not selecting 01:22.080 --> 01:22.880 the geometry. 01:23.580 --> 01:30.360 So we could while we're animating, just simply click on this button up here, which is to turn off 01:30.360 --> 01:31.620 selection of geometry. 01:31.620 --> 01:32.160 If you right. 01:32.160 --> 01:39.540 Click this, you can specify a little more specifically what type of geometry you don't want to select. 01:39.930 --> 01:45.540 So with that checked off there, we now cannot select any geometry in the scene. 01:46.170 --> 01:47.700 And that's a pretty quick way. 01:47.700 --> 01:49.950 When I start animating, I just click that anyways. 01:50.250 --> 01:52.160 And I also will click this one. 01:52.170 --> 01:54.840 This one means that you can't select joints. 01:54.840 --> 01:55.350 In this case. 01:55.350 --> 01:58.650 There's no joints in this rig, so we don't have to worry about that. 01:58.650 --> 02:03.600 But sometimes riggers don't hide joints and they're inside of geometry. 02:03.600 --> 02:10.440 So sometimes you can't even see them unless you get four your keyboard or you can look inside but and 02:10.470 --> 02:13.410 you can hit six or a keyboard, by the way, to see the textures of this rig. 02:13.710 --> 02:16.620 It's has some procedural textures in it. 02:16.620 --> 02:18.600 So you can hit six to show that. 02:19.200 --> 02:21.960 But in our case, we don't really need to worry about this one. 02:21.960 --> 02:24.690 But just for good practice, we'll leave that off as well. 02:25.260 --> 02:29.670 But let's say for some reason we want to be able to select this little box here. 02:29.670 --> 02:33.900 We want to select that geometry or the plane or something and but not this. 02:34.260 --> 02:37.170 So what we can do is turn that back on and do something else. 02:37.170 --> 02:41.610 We can select all of the geometry here and put it into a display layer. 02:41.880 --> 02:46.380 But for us to do that, it's maybe a little tricky to select all the stuff and not the curves. 02:46.620 --> 02:50.280 So let's open up the outliner and take a look at this rig real quick that I made. 02:50.700 --> 02:56.640 So we get on the Windows outliner and you can see that the robot ball rig has a group here. 02:57.060 --> 03:03.570 If we toggle that down, we can see there are these two kind of main groups here, the control group 03:03.570 --> 03:04.410 and the Geo Group. 03:04.410 --> 03:06.480 And we know we don't want to select the controls. 03:06.710 --> 03:11.880 We just want the geo here and we want to put that into its own display layer and display layers have 03:11.880 --> 03:13.290 a couple of different purposes. 03:13.830 --> 03:18.180 If we hit this far right button, it'll take whatever we have selected and put it into that display 03:18.180 --> 03:18.540 layer. 03:18.570 --> 03:22.980 If we want to add something to the display layer afterward, like we forgot to select maybe the ground 03:22.980 --> 03:26.490 or something, we can right click and say add selected objects. 03:26.880 --> 03:30.600 So what this does is it gives us several different options here. 03:30.600 --> 03:37.350 And let me just rename this so we know it's a no touch and we'll save it. 03:37.830 --> 03:41.910 And what we can do, we can actually turn all the geometry in that layer on and off. 03:42.600 --> 03:47.970 But we could also turn on the reference this T means template. 03:48.420 --> 03:52.230 So it'll make it kind of wireframe even if we're not in wireframe mode. 03:52.470 --> 03:55.560 But what we're interested in is the R, which means reference. 03:55.860 --> 03:58.620 So we know we can't actually touch that stuff. 03:58.620 --> 04:02.970 But if we wanted to touch the geometry of this cube, we can still do that. 04:03.510 --> 04:05.070 So that's super helpful. 04:05.070 --> 04:10.110 And I typically will set up my scenes like this before I get started animating so that I know I'm not 04:10.110 --> 04:15.060 going to get into trouble later on by accidentally setting keys on geometry or joints or something weird 04:15.390 --> 04:16.940 that I don't want to. 04:17.400 --> 04:21.630 So the other cool thing we can do is put the controls in their own layer as well. 04:21.960 --> 04:24.660 And I'll show you one other feature of display layers. 04:29.440 --> 04:36.550 Now, if we play this back, I'm going to hit alt v, you can see there's no animation yet, but we 04:36.550 --> 04:37.500 can see the curves. 04:37.840 --> 04:43.570 Now, typically when you're watching animation back, you don't want to really see the curves themselves 04:43.570 --> 04:47.980 because the kind of breaks, the silhouette, you won't be able to see the silhouette and follow the 04:47.980 --> 04:50.430 geometry, which is what's going to be rendered later. 04:50.800 --> 04:54.080 So the curves aren't useful to see when we're playing back. 04:54.430 --> 04:59.500 So what we can do now, if they're in their own layer, as we can just hit the P little letter here 04:59.500 --> 05:00.550 and this square. 05:00.880 --> 05:02.680 So that's in playback. 05:03.370 --> 05:07.590 When we hit Alvie, they'll automatically hide and when we stop playing back, they'll come back. 05:07.990 --> 05:13.300 So that's a very useful feature and I think it's newer and Miah twenty eighteen. 05:13.720 --> 05:17.950 So let's go into the next lesson where we'll actually begin animating this and learn a little bit more 05:17.950 --> 05:19.330 about the principles of animation. 05:19.390 --> 05:20.020 Thanks for watching.
