WEBVTT 00:00.710 --> 00:04.650 Welcome to parent and child objects in this video. 00:04.650 --> 00:07.730 We're going to see how parents can group together objects. 00:07.760 --> 00:10.080 Essentially that becomes their children. 00:10.130 --> 00:13.820 We're going to create a hierarchy which is easy to navigate. 00:14.030 --> 00:17.370 We'll be using this to logically group our pieces together. 00:17.660 --> 00:23.120 Now when we're doing parents and children the children can our children and those children our children 00:23.120 --> 00:27.670 as well so you can have a whole family there so a parent child or grandchild and great grandchild et 00:27.660 --> 00:28.660 cetera. 00:29.030 --> 00:35.090 So looking at our hierarchy now going from left to right this is roughly how the outliner will be looking 00:35.660 --> 00:38.090 where we have the chess scene itself. 00:38.090 --> 00:43.210 There will be a lightsome objects in our in the camera in a couple of other things as well. 00:43.280 --> 00:48.350 Now the moment we've already got an empty in our scene which is the white pieces and under that we're 00:48.350 --> 00:53.320 going to put the bournes the rocks the Knights the bishops king and queen etc.. 00:53.660 --> 00:59.360 And looking at the number of other objects we have in our scene it might be worthwhile. 00:59.390 --> 01:01.060 We'll see in the outline. 01:01.570 --> 01:02.650 Now look at the numbers there. 01:02.660 --> 01:07.970 It might be worthwhile actually putting the pawns in their own little empty as well. 01:07.970 --> 01:13.760 Just so we can have good control over all of those bits and bobs but we'll see how that looks in the 01:13.810 --> 01:15.950 outliner when we start working with it. 01:15.950 --> 01:19.380 So talking about the outliner Let's pop over into blender. 01:21.190 --> 01:27.250 Okay so over in blender we just need to fit in while first thing I'm going to do is just tidy up our 01:27.250 --> 01:32.920 view so I'm going to hide the time line at the bottom so as we're not using it to hide the tall shelf 01:32.980 --> 01:35.870 and hide the properties panel of three deer. 01:36.160 --> 01:40.810 I'm going to move this section across because we're mainly going to be dealing with the outliner in 01:40.810 --> 01:41.550 this case. 01:41.590 --> 01:46.810 I'm going to leave the 3D view here because when we select our individual meshes we can see what's going 01:46.930 --> 01:47.790 on. 01:48.280 --> 01:54.040 Okay so the first thing we need to do here is start grouping these items together and we can see here 01:54.040 --> 01:56.650 we have our scene inside the scene. 01:56.650 --> 01:58.060 There are a load of options. 01:58.060 --> 02:01.630 We've got at least one mesh objets And so we've got several mesh objects. 02:01.630 --> 02:03.860 It's Which is why we're doing this organization. 02:03.880 --> 02:06.880 We've got the camera we've got the lamp as well. 02:06.940 --> 02:10.400 These can all be Parenthood or childed if you want to. 02:10.630 --> 02:17.530 So I think with all of this in the hierarchy already it might be a good idea to group even our small 02:17.530 --> 02:19.100 pieces together. 02:19.150 --> 02:24.870 So the first thing I'm going to do is how to assign a parent object to its children. 02:25.000 --> 02:29.680 So we start with the bishops here because we've only got two of them so it won't be a repetitive task 02:29.680 --> 02:30.460 anyway. 02:30.640 --> 02:35.050 But at the moment they've got they're just by themselves in our hierarchy. 02:35.140 --> 02:43.900 So I'm going to give them an empty first of all so I'm going to go and empty again just a plain access 02:43.900 --> 02:46.040 is absolutely fine. 02:46.690 --> 02:50.360 I want to call this empty wights bishops. 02:52.880 --> 03:01.010 So the way that's a parent is done is you select in the order or rather the last thing that you select 03:01.040 --> 03:03.120 will become the parent. 03:03.140 --> 03:08.810 After all three items are selected ending with the thing we want to be the parents. 03:08.900 --> 03:15.710 We can go down to object where it's all scroll up to where it says parent and just go to object and 03:15.710 --> 03:16.650 we can see here. 03:16.730 --> 03:22.010 Control ampie is the shortcut and then it will say step parent to. 03:22.010 --> 03:24.080 And we just want objects here. 03:24.470 --> 03:25.420 So now we've done that. 03:25.430 --> 03:30.710 We can see that white Bishop's has two meshes associated it looking at the outliner. 03:30.710 --> 03:33.940 And when we drop that down we can see bishops beneath. 03:34.010 --> 03:40.720 Now all you will notice and was a bit counterintuitive when I started using blender was when you click 03:40.730 --> 03:44.760 white bishops it only selects are empty here. 03:44.990 --> 03:47.730 It does not select the meshes beneath. 03:47.840 --> 03:53.030 If you want to select everything beneath it depending on what you want to do says Say we wanted to hide 03:53.030 --> 03:55.940 both the white bishops without selecting them all. 03:56.060 --> 04:01.160 We could control and click on our empty and that would select everything. 04:01.160 --> 04:08.210 Then if we click the little eye or pressed H We could hide all of those by clicking control you have 04:08.210 --> 04:13.660 to have control down when you click so to select them all we can select them all in the outline. 04:13.670 --> 04:18.770 By holding down control to high the more we'd have to do the same and that similar operation applies 04:18.770 --> 04:20.620 to everything else. 04:20.630 --> 04:30.670 Finally we can test this inside white pieces so we select our first objects or rather in this where 04:30.700 --> 04:35.840 it is an object we select our first object and then we select our second object was holding downshifts 04:35.850 --> 04:42.820 of both a selected and then go to object parents an object and again control and p.. 04:42.860 --> 04:48.170 So in this window here you could just go control and pay and set parent to object. 04:48.170 --> 04:56.080 Now under white pieces we have white bishops and under that we have low poly Bishop 1 and 2. 04:56.180 --> 04:59.880 In fact I might name them one and two. 04:59.900 --> 05:02.770 Now just for neatness. 05:03.140 --> 05:04.860 Okay guys it's Challenge time. 05:04.880 --> 05:11.780 I'd like you to finish off the organization of the hierarchy so assign the porn's a parent empty called 05:11.810 --> 05:15.960 White pawns and then make the white pawns empty. 05:15.980 --> 05:21.490 A child of white pieces palls of you now and go give that a go. 05:23.040 --> 05:23.880 Okay guys. 05:24.000 --> 05:24.960 Welcome back. 05:24.960 --> 05:27.310 Let's hop straight on over into blender. 05:28.270 --> 05:31.330 Right so we're almost here with these porn. 05:31.330 --> 05:37.090 So the first thing we need to do is create our empty that we're gonna assign as the parent to all of 05:37.090 --> 05:38.050 these pawns. 05:38.050 --> 05:43.220 So add empty plane axis. 05:43.420 --> 05:46.320 I'm going to call this all white pawns. 05:46.320 --> 05:47.340 B w an S. 05:47.350 --> 05:48.190 Excellent. 05:48.220 --> 05:50.900 I'm going to select all of these. 05:50.920 --> 05:55.530 Holding down shift as we go with the final one being white pawns. 05:55.750 --> 06:02.750 Then I'm going to go over here cause a has to be in the 3-d window control and pee sit them to the object. 06:02.810 --> 06:05.310 And so that's tided up our hierarchy no end. 06:05.350 --> 06:10.750 And then finally I'm going to select white pawns it's already selected and put them under white pieces 06:10.750 --> 06:15.460 again control ampie and set it to the object. 06:15.460 --> 06:18.070 And now we've got a much neater hierarchy. 06:18.250 --> 06:22.650 She can see there are now the White pieces and the chessboard. 06:22.930 --> 06:23.410 Excellent. 06:23.410 --> 06:27.900 And when we open up that we have our white bishops and white porn. 06:28.020 --> 06:32.450 Oh it looks like we had the series of objects selected so I'd made a mistake there. 06:32.590 --> 06:35.120 So let's reassign these. 06:35.980 --> 06:39.110 The parents object of white pawns. 06:39.250 --> 06:44.010 I forgot to D before going forward and that's excellent that's popped. 06:44.020 --> 06:48.820 All of those under there are white pieces white bishops who got two meshes under their white pawns we 06:48.820 --> 06:50.860 should have eight meshes which we do. 06:50.950 --> 06:56.500 And if you wanted to you could go through here and name these appropriately if you wanted to and to 06:56.500 --> 06:59.550 keep that naming convention going without doing too much work. 06:59.560 --> 07:02.860 The first one which has been called zero to seven. 07:02.860 --> 07:03.500 Excellent. 07:03.640 --> 07:05.510 How did you guys get on. 07:05.590 --> 07:07.250 See you in the next lecture.
