1

00:00:05,940 --> 00:00:08,090

Now though we took a look at what an empty is.



2

00:00:08,130 --> 00:00:14,820

Let's take a look at something else and we will see how the empty works in relation to that.



3

00:00:14,820 --> 00:00:22,740

So in this video when you look at parent child relationship with Blendr now parent child relation sounds



4

00:00:23,040 --> 00:00:32,310

it does as it sounds it sets up a parent and a child object and the child object basically copies the



5

00:00:32,310 --> 00:00:33,890

parent object.



6

00:00:34,050 --> 00:00:37,230

So to show you it's much easier.



7

00:00:37,230 --> 00:00:38,660

So let's go ahead and do that.



8

00:00:38,820 --> 00:00:40,360

Let's hit alt H.



9

00:00:41,150 --> 00:00:42,560

And unhide everything.



10

00:00:42,770 --> 00:00:47,690

And this way we will see what our empty does as well and how it's used.



11

00:00:47,690 --> 00:00:53,780

So if I select my ball right here you can see that if I select the empty in the middle and move it or



12

00:00:53,780 --> 00:00:57,310

rotate it nothing's happening it's just kind of rotating itself.



13

00:00:57,710 --> 00:01:00,820

Now the ball is independent as well.



14

00:01:01,630 --> 00:01:06,530

But if I select the ball and then shift select the empty.



15

00:01:06,730 --> 00:01:10,720

So you have to select the ball first and then the empty not the other way around.



16

00:01:10,720 --> 00:01:12,950

Otherwise it will have a different result.



17

00:01:13,870 --> 00:01:19,690

Because now for a child parent relationship it basically works like this.



18

00:01:19,780 --> 00:01:23,120

The first object that you select will be the child.



19

00:01:23,410 --> 00:01:27,080

And the second object you select will be the parent.



20

00:01:27,520 --> 00:01:33,070

So if we select the ball then the empty by holding Shift right clicking and then control P. You can



21

00:01:33,070 --> 00:01:38,850

see that says set parent to object and just select object right there.



22

00:01:38,860 --> 00:01:45,010

Now the ball is the child and the empty right here is the parent.



23

00:01:45,010 --> 00:01:52,260

So if we select the empty you can see that if we move it rotate it or do anything with it.



24

00:01:52,420 --> 00:02:00,610

The ball will copy the empty because it the ball is the child and the empty is the parent.



25

00:02:00,610 --> 00:02:05,100

So anything we do with the empty the ball will follow along.



26

00:02:05,110 --> 00:02:06,140

So that's pretty cool.



27

00:02:06,160 --> 00:02:10,520

And this is a great way and you could still move the ball independently from the empty.



28

00:02:10,750 --> 00:02:14,060

But when you move the empty the ball follows.



29

00:02:14,070 --> 00:02:18,820

Now you don't want to move the ball independently from the empty in this example but you could see that



30

00:02:18,820 --> 00:02:26,650

if I do you will see this dotted line from the ball all the way to the empty right here showing that



31

00:02:26,980 --> 00:02:31,230

the ball is a child to the parent of the empty.



32

00:02:31,330 --> 00:02:32,270

Pretty cool.



33

00:02:32,500 --> 00:02:38,830

So what this allows for us to do is just have because now we're also going to select the lattice by



34

00:02:38,830 --> 00:02:48,440

right clicking it and then shift selecting the empty and then hitting control P and setting the parent



35

00:02:48,500 --> 00:02:51,110

to the empty with the lattice as well.



36

00:02:51,110 --> 00:02:59,510

Now if we select the empty you can see that if we grab it and move it it will move both the lattice



37

00:02:59,600 --> 00:03:08,510

and the ball because they are both child of the empty as you can see via these lines right here.



38

00:03:08,540 --> 00:03:13,190

They are both Parenthood to the empty that we have right here.



39

00:03:13,190 --> 00:03:14,210

Now let me undo that.



40

00:03:14,210 --> 00:03:15,970

Make sure they're still there.



41

00:03:16,010 --> 00:03:23,770

And so what this allows for us to do is basically move one single object and at the same time it moves.



42

00:03:23,770 --> 00:03:30,620

Both of these otherwise we would have to animate all we would have to animate the ball and the lattice



43

00:03:30,800 --> 00:03:32,600

in the same movement.



44

00:03:32,600 --> 00:03:38,270

For example if we want the ball to move this way then we'd have to move the lattice as well and it's



45

00:03:38,270 --> 00:03:39,380

much easier this way.



46

00:03:39,380 --> 00:03:43,670

This way you only have to focus on empty and you animate the empty.



47

00:03:43,790 --> 00:03:48,160

And it will animate both of them for you and they will follow the empty.



48

00:03:48,410 --> 00:03:50,930

So that is parent child relationship.



49

00:03:51,120 --> 00:03:56,920

Are the it's very very useful and to clear a parent child relationship.



50

00:03:56,930 --> 00:04:04,300

All you do is select your objects for example the sphere and then the lattice and that are Asare the



51

00:04:04,310 --> 00:04:08,300

empty and hit alt P and clear parent.



52

00:04:08,570 --> 00:04:13,940

Now if I select the empty you can see that the ball is no longer parents add to it.



53

00:04:14,210 --> 00:04:20,450

Let's go ahead and parents it back by selecting the ball shift right clicking into empty control P and



54

00:04:20,450 --> 00:04:21,990

said the parent object.



55

00:04:22,190 --> 00:04:23,800

And there we have it.



56

00:04:23,900 --> 00:04:29,840

So for our animation we're going to be animating the empty right here and it's going to affect both



57

00:04:29,840 --> 00:04:31,960

the ball and the lattice.



58

00:04:32,120 --> 00:04:32,640

All right.



59

00:04:32,810 --> 00:04:34,520

I'll see you in the next video.



60

00:04:35,110 --> 00:04:35,610

All right.



61

00:04:35,630 --> 00:04:37,790

Here's one of my favorites.



62

00:04:38,270 --> 00:04:42,750

I'm just kidding they're all my favorites like a flowing river like a rushing wind.



63

00:04:42,830 --> 00:04:46,260

Your essence never changes yet is never the same.



64

00:04:46,280 --> 00:04:50,160

Don't try to hold onto the old break away from the chains of your past.



65

00:04:50,270 --> 00:04:52,430

You knew that they could never last.



66

00:04:52,460 --> 00:04:53,600

It is finally time.



67

00:04:53,600 --> 00:04:59,900

Spread the wings of your mind embrace faith leap and take flight and you'll find the freedom is your



68

00:04:59,900 --> 00:05:00,920

birthright.



69

00:05:01,160 --> 00:05:05,170

I ladies and gentlemen let go of the past and move on to something better.



70

00:05:05,360 --> 00:05:06,800

Keep on blenny my friends.



71

00:05:06,860 --> 00:05:10,430

I'll see you in the next video and keep rocking it.



72

00:05:10,460 --> 00:05:10,850

All right.



73

00:05:10,850 --> 00:05:11,970

Ciao for now.
