WEBVTT 00:00.360 --> 00:06.840 Welcome to adding bones to our armature in this video you will learn how to add additional bones to 00:06.840 --> 00:12.900 an armature and understand that a Kneebone does not have to be connected to the previous one. 00:12.900 --> 00:14.890 Let's talk quickly about bone structure. 00:15.030 --> 00:17.240 There are three main components of a bone. 00:17.250 --> 00:23.970 We've got the tail tip a body and a head or roots and simply put the head of roots where the bone starts. 00:23.970 --> 00:28.310 And then you've got the body connecting it to the tail or the tip where attends. 00:28.320 --> 00:31.860 Now be using that terminology lots as we talk about bones. 00:31.940 --> 00:35.360 So I just thought I'd explain and show you what I'm talking about. 00:36.340 --> 00:38.210 So now we've got the bone structure in our heads. 00:38.260 --> 00:40.560 Let's hop straight on over into blender. 00:41.400 --> 00:46.040 So we were at this stage in our lamp at the moment and we've actually got some arms here. 00:46.050 --> 00:47.630 We've got our lower arms made. 00:47.750 --> 00:52.410 Now we have a look at the reyk so far we've only got so just quickly little eyeball here. 00:52.440 --> 00:53.940 I had hidden it before. 00:54.060 --> 00:56.560 We've got just one bone in that wreck. 00:56.790 --> 01:01.350 Now I'm going to do a bit of experimenting and put in lots of things in so we're going to hop over into 01:01.350 --> 01:02.740 a new blender file. 01:04.550 --> 01:07.760 Now once you're in a new blender File we're going to add an armature. 01:07.760 --> 01:12.090 So no go shift in A and add a single bone. 01:12.330 --> 01:14.460 Oh it looks like my key strokes aren't showing. 01:14.520 --> 01:16.490 Looks like I can't be full screen. 01:16.850 --> 01:17.180 There we go. 01:17.180 --> 01:18.400 We're back to here. 01:18.440 --> 01:19.310 Mikey Shaw it's a show. 01:19.310 --> 01:22.250 So we've added an armature and it's over here. 01:22.430 --> 01:28.760 When we go to the armature properties and just make sure that x ray is turned on so we can see what's 01:28.760 --> 01:33.620 going on so we can see arm bone in the scene here. 01:33.650 --> 01:39.110 And we want to go into edit mode so I'm going to hit tab and go across the edit mode and to add a new 01:39.110 --> 01:42.550 bone that's connected to the tail of the last bone. 01:42.740 --> 01:48.230 You literally extrude so you can press the e.t. and there's our new bone. 01:49.360 --> 01:52.350 And you can keep doing it again and again and again. 01:52.360 --> 01:58.810 Now if for some reason you needed an extra bone in on this area here you could then press E. 01:58.840 --> 02:03.640 Coming from there and you can generate as many bones from a single point and she liking because you 02:03.640 --> 02:05.150 can move those around. 02:06.100 --> 02:09.060 Okay so I'm just going undo some of that quickly. 02:09.810 --> 02:15.720 Because what you would generally want to do is just lock it to an axis so I'm going to make make-up 02:15.780 --> 02:16.540 now. 02:16.650 --> 02:20.700 Our lamp sort of flow that we're going to do so we got a STEM coming out there. 02:20.880 --> 02:27.130 We'll have a well I want to lock that to the y axis in this case so here we go. 02:27.950 --> 02:30.770 Were everywhere except Z actually saw a shift in Z. 02:30.890 --> 02:36.370 So a shift in X and that's now on there so we'll come back from there like that will come up for the 02:36.370 --> 02:39.200 next bit and we'll have the lamp there. 02:39.300 --> 02:41.860 The little light at the top. 02:42.010 --> 02:48.970 Now one of the things you may want to do when using bones is well the way that the bones are constructed 02:49.660 --> 02:51.730 defines the movement. 02:52.150 --> 02:58.150 So here if we wanted to add in let's say one across for the baseplate if we wanted to make it wobble 02:58.540 --> 03:04.450 ever so slightly rather than being linked directly to here it wouldn't be that natural but we could 03:04.450 --> 03:06.890 add a little bit of wobble to it. 03:07.000 --> 03:10.870 We may find that this is the wrong way round and a couple of ways are flipping that round. 03:10.870 --> 03:16.490 We can go to armature and switch direction and you can see the shortcut key there is Alton f. 03:16.600 --> 03:22.230 So if you ever need to switch the direction of a bone you can do it an F and it will flip it round. 03:22.480 --> 03:26.500 And that's the same with all of our bones. 03:26.500 --> 03:27.070 Brilliant. 03:27.100 --> 03:31.210 And then of course if you've put the bones in the wrong order for whatever reason you can select multiple 03:31.210 --> 03:34.520 ones and then flip the whole lot. 03:35.600 --> 03:41.010 Now if we want to add another bone to our scene to our armature. 03:41.030 --> 03:44.720 In fact that's not connected directly to any of the others. 03:44.720 --> 03:47.520 There are certain circumstances where you'll want to do this. 03:47.600 --> 03:52.730 We won't be touching on them just yet but just want to quickly show you you simply position the 3D cursor 03:52.730 --> 03:53.960 where you want the new bone to be. 03:53.960 --> 03:58.350 So on the planet over there and I can just go shift in a for ADD. 03:58.550 --> 04:04.760 And there you go there's a new bone finally of course when you've got a complicated scene with several 04:04.760 --> 04:09.060 bones in it do you remember to name your bones themselves. 04:09.080 --> 04:14.630 So when we click on a bone we can go over to the bone properties and at the moment you can see as we 04:14.630 --> 04:17.940 click on these this bone changes so we've got that. 04:18.180 --> 04:23.530 I've turned off x ray So we've got the bone at the bottom here which is just going to be called bone. 04:23.570 --> 04:29.150 And then we've got bone 0 0 1 0 2 0 3 and this was going to be 4 5 6 7 etcetera. 04:29.330 --> 04:30.890 And they're not very descriptive. 04:30.890 --> 04:34.700 It is very important that we name them appropriately. 04:34.700 --> 04:38.490 I'm not going to name them at this point in time because I'm just about to get rid of this file. 04:38.660 --> 04:42.700 But I do suggest whenever you create a bone you give it an appropriate name. 04:44.420 --> 04:46.160 Okay so it's Challenge time. 04:46.220 --> 04:50.050 I'd like you to add a second bone to the first one. 04:50.150 --> 04:56.340 So add another bone making sure it is locked to the appropriate axis name the bone. 04:56.360 --> 05:02.480 That's very important position the bones tail in line with the top of the lower arm and then finally 05:03.320 --> 05:07.210 and then finally parent the lower arm to the new bone. 05:08.340 --> 05:16.350 And I know that some of you are having problems with the first set of low arms with the mirror modifier 05:16.410 --> 05:17.560 UN applied. 05:17.700 --> 05:24.450 So if you are having problems do apply that's also check that you have applied any transforms that you've 05:24.450 --> 05:24.970 made. 05:25.080 --> 05:29.400 If you've even edited something in object mode its rotation or its scale. 05:29.520 --> 05:33.210 Those can adversely affect the armature and movement. 05:33.210 --> 05:35.380 So make sure any of those are applied with. 05:35.390 --> 05:37.680 Control and a as well. 05:37.680 --> 05:40.230 That should hopefully stave off any problems. 05:40.410 --> 05:43.890 So go ahead pause a video now and give that a go. 05:46.180 --> 05:46.770 Okay guys. 05:46.780 --> 05:47.770 Welcome back. 05:47.770 --> 05:50.070 Let's hop straight on over into blender. 05:51.160 --> 05:54.200 So back over on our animated lamp. 05:54.460 --> 05:58.800 The first thing I need to do is just turn on the lamp so I can see it over there. 05:58.810 --> 06:01.300 So now we've got this in place. 06:01.300 --> 06:01.990 I can. 06:01.990 --> 06:03.880 I'm going to not try and select it in here. 06:03.910 --> 06:08.870 I'm just going to end up and geometry I'm just going to left clicking the outline on the lamp rake and 06:08.920 --> 06:17.080 the sweep right round to the left for you in orthographic which should mean that when I then pop into 06:17.260 --> 06:24.210 edit mode and extrude from there I can bring it up and we see the in the lower left. 06:24.220 --> 06:29.710 You can see the numbers going round and the change in the x coordinate is nothing but just to make sure 06:29.740 --> 06:33.140 I'm just going to go shift and X.. 06:33.240 --> 06:34.260 There you go it's locked. 06:34.270 --> 06:37.900 Then I'm just going to put it into the approximate position. 06:37.900 --> 06:43.690 Now you may notice that this was like the hinge point is girl the pivot point is going to be in the 06:43.690 --> 06:46.010 wrong place and you are right. 06:46.090 --> 06:49.900 But don't worry about that at the moment because if we go and correct it with our current knowledge 06:50.230 --> 06:54.790 it's going to make some funny stuff happen on the model and we're going to deal with that in the next 06:54.790 --> 06:55.500 lecture. 06:55.780 --> 06:59.230 But now we've got that in the right place we've got a couple of further things to do. 06:59.230 --> 07:01.880 First of all it's just parenting the bone. 07:02.020 --> 07:06.880 I'm going to name the bone actually first so I'm going to hop into the bone here it's going to be called 07:06.880 --> 07:12.340 STEM 001 because that was based on the first one and I'm going to call this lower arm so we know what 07:12.340 --> 07:13.540 the bone is for. 07:13.560 --> 07:18.290 In fact caps lock on which always helps lower arm. 07:18.300 --> 07:18.680 Brilliant. 07:18.680 --> 07:21.810 So that's named and then going to select the lower arm. 07:22.820 --> 07:24.210 Hop into object mode. 07:25.230 --> 07:28.750 Shift and select that and go control. 07:28.780 --> 07:31.360 MP imperative to the bone. 07:31.440 --> 07:32.010 So there we go. 07:32.020 --> 07:33.390 That's now all parenting. 07:33.540 --> 07:39.540 And if we decide to move any of our armature the rest of it moves with it so we know that it's all parent 07:39.540 --> 07:40.340 ID. 07:40.620 --> 07:41.300 Okay. 07:41.370 --> 07:42.620 How did you guys get on. 07:42.690 --> 07:48.560 Please share in the discussions and we'll solve this little hinge problem in the next lecture.
