00:00:05,910 --> 00:00:10,640

All right in this video let's take a look at something called Shape keys.



2

00:00:10,850 --> 00:00:15,900

So shape keys What are they and why do we use them and why do we need them.



3

00:00:15,920 --> 00:00:22,010

What shape keys if we select our lattice modifier you can see that right here we have something called



4

00:00:22,250 --> 00:00:31,930

Shape keys now shape keys basically allow for you to animate modify and edit your mesh in edit mode.



5

00:00:32,010 --> 00:00:35,120

So that's pretty much what it does.



6

00:00:35,120 --> 00:00:39,600

Whereas right here we animated objects in Object mode.



7

00:00:39,770 --> 00:00:42,130

What if we want our ball.



8

00:00:42,260 --> 00:00:47,890

Let's say we wanted Let's actually add in a new Kuban do this with this shift.



9

00:00:47,960 --> 00:00:49,290

And mesh cube.



10

00:00:49,430 --> 00:00:52,170

We'll go to our lattice to do it right after as well.



11

00:00:52,280 --> 00:00:54,740

Hit delete on the keyboard to zoom into your cube.



12

00:00:55,940 --> 00:01:02,330

And now hit tab to go into Edit Mode W and let's subdivide it three times by W..



13

00:01:02,340 --> 00:01:04,540

Subdivide and left clicking.



14

00:01:04,620 --> 00:01:11,830

Now if you go to the data on the cube as well it also has a shape key group.



15

00:01:11,840 --> 00:01:20,390

Now as I was saying we can animate our cube by moving it like so and rotating it and scaling it.



16

00:01:20,540 --> 00:01:24,830

But let's say What if we want our cube to be like this.



17

00:01:24,830 --> 00:01:31,680

And then all of a sudden have spiky parts to it that it just you know it becomes a flat cube and then



18

00:01:31,700 --> 00:01:34,060

becomes a spiky cube all of a sudden.



19

00:01:34,190 --> 00:01:36,780

How would you animate something like this.



20

00:01:36,980 --> 00:01:39,470

Well that's where shapes he's come in.



21

00:01:39,470 --> 00:01:46,820

They actually allow for you to animate the editing portion of your mesh whereas right here in Object



22

00:01:46,820 --> 00:01:52,990

mode we're only we're only animating the object when we go to Edit mode and use shaped keys.



23

00:01:53,120 --> 00:02:00,410

We could actually animate the individual vertices and faces and shape keys are what we are going to



24

00:02:00,410 --> 00:02:02,540

use for facial features.



25

00:02:02,600 --> 00:02:08,360

If you make a character you will use shape keys to animate you know the mouth the lips and everything.



26

00:02:08,360 --> 00:02:13,590

So let's go ahead and take a quick look at shaped keys and how they work.



27

00:02:13,700 --> 00:02:17,950

And let's do a quick little example here with our cue.



28

00:02:18,110 --> 00:02:19,000

I'm going to hit.



29

00:02:19,010 --> 00:02:22,660

I'm going to close this window just so we have a full window for this video.



30

00:02:22,910 --> 00:02:26,900

And now with our cube selected I'm going to add a shape key.



31

00:02:27,850 --> 00:02:31,280

Now the basis shape key is always there when you add it.



32

00:02:31,330 --> 00:02:40,170

And this is basically the shape key or the shape of your object as it is in its original format.



33

00:02:40,240 --> 00:02:49,300

So the shape key as the name implies determines the shape of your mesh via the editing or via the edit



34

00:02:49,300 --> 00:02:54,030

mode and the Via the vertices and the faces so basis.



35

00:02:54,250 --> 00:02:57,470

This is how it will look on the basis keyframe.



36

00:02:57,470 --> 00:03:00,950

Now we just have to add another one by hitting the plus sign.



37

00:03:01,390 --> 00:03:04,340

And now we have one called key one.



38

00:03:04,510 --> 00:03:07,140

We could go ahead and rename it by double clicking.



39

00:03:07,360 --> 00:03:16,240

Let's name it is Nike underscore hube and hit enter.



40

00:03:16,250 --> 00:03:18,780

Now let's bring the value all the way.



41

00:03:18,820 --> 00:03:21,120

Let's go into edit mode first.



42

00:03:21,190 --> 00:03:26,790

Actually nevermind Let's stay in object mode and bring the value all the way up.



43

00:03:26,800 --> 00:03:30,110

Sometimes I think we could do things both in that it mode in object mode.



44

00:03:30,280 --> 00:03:32,410

No you can only do it in Object mode.



45

00:03:32,410 --> 00:03:39,130

So an object might bring the value all the way up to 1 and now hit tab to go into edit mode hit control



46

00:03:39,130 --> 00:03:48,110

tab to go into vertex select mode and let's select some vertices and hit G and Z and just grab them



47

00:03:48,180 --> 00:03:49,960

g x.



48

00:03:50,320 --> 00:03:57,300

Grab this one as well gee g y and let's do one more here G.



49

00:03:57,460 --> 00:03:59,190

X.



50

00:03:59,330 --> 00:03:59,820

All right.



51

00:03:59,960 --> 00:04:04,510

So that is our spiky cube we can hit tab to go back into object mode.



52

00:04:05,690 --> 00:04:13,250

And now you will see that the value out one the cube will look like this and add zero.



53

00:04:13,460 --> 00:04:16,160

The cube looks normal and it looks flat.



54

00:04:16,160 --> 00:04:17,630

How awesome is that.



55

00:04:17,630 --> 00:04:19,150

That's pretty cool isn't it.



56

00:04:19,340 --> 00:04:27,950

So you could actually then animate these values by inserting a keyframe just like we did when you animate



57

00:04:28,280 --> 00:04:29,510

a object.



58

00:04:29,510 --> 00:04:36,790

So if you animate an object you could just hit I and insert a key frame for the location rotation scaling.



59

00:04:36,920 --> 00:04:44,690

Here you would insert a key frame for the value you could actually insert key frames for values of anything.



60

00:04:44,690 --> 00:04:45,740

Believe it or not.



61

00:04:45,950 --> 00:04:48,300

Or the majority of things I should say.



62

00:04:48,410 --> 00:04:50,020

So let's go ahead and try that.



63

00:04:50,030 --> 00:04:51,760

Let's go to frame 1.



64

00:04:53,330 --> 00:04:56,750

And in frame 1 let me hide my ground floor as well.



65

00:04:57,640 --> 00:05:03,660

In Flint and frame one I'm going to hit I with my mouse hovered over this value.



66

00:05:03,730 --> 00:05:11,080

So it's going to tell Blendr that on frame 1 the value of this shape key is going to be 0.



67

00:05:11,170 --> 00:05:12,830

So go ahead and hit I.



68

00:05:13,330 --> 00:05:15,830

And we get a yellow.



69

00:05:16,040 --> 00:05:19,790

We get yellow over the values showing that there is now a keyframe.



70

00:05:20,230 --> 00:05:30,400

Let's go to frame 15 15 and bring the value all the way up to 1 and then hit I with your mouse hovered



71

00:05:30,400 --> 00:05:34,060

over the value and you can see added the key frame there.



72

00:05:34,090 --> 00:05:36,820

And a key frame in the timeline as well.



73

00:05:36,970 --> 00:05:44,860

So now if we scroll through here you can see that we're actually able to animate the editing portion



74

00:05:44,980 --> 00:05:50,800

of an object that is pretty awesome using shaped keys of course.



75

00:05:50,800 --> 00:05:53,440

So that is how you use shape keys.



76

00:05:53,440 --> 00:05:55,600

Now couple other things that we need.



77

00:05:55,600 --> 00:05:59,520

Take a look at or we could take a look at this right here.



78

00:05:59,710 --> 00:06:03,310

Let's say let's go to frame 30 right here.



79

00:06:03,330 --> 00:06:05,290

The maximum amount is 1.



80

00:06:05,310 --> 00:06:08,000

So you could bring it all the way up to 1.



81

00:06:08,010 --> 00:06:13,940

How about if we want to inverse these spikes and bring them into the cube.



82

00:06:14,280 --> 00:06:20,160

Well we could go ahead and you know add in and you keyframe or a new shape key.



83

00:06:20,640 --> 00:06:28,020

And with this one go into Edit Mode bring these in and do that all over again.



84

00:06:28,020 --> 00:06:35,770

But since the since going in and going out is the exact same thing just inversed.



85

00:06:35,790 --> 00:06:43,050

So going out is this way and going in would be the same thing but in the opposite direction what we



86

00:06:43,050 --> 00:06:45,440

could do is you could see right here if we go to zero.



87

00:06:45,450 --> 00:06:51,630

It's completely flat but our minimum value is actually set to zero.



88

00:06:51,630 --> 00:07:00,460

So if we set this negative one you can see that now we have more to play with our value option here.



89

00:07:00,470 --> 00:07:08,270

So now if we bring it down you could see that the value is going in words it's going to a negative to



90

00:07:08,270 --> 00:07:13,560

a negative number or two and negative.



91

00:07:13,700 --> 00:07:16,970

And I came in from my work today yet to a negative value.



92

00:07:16,970 --> 00:07:21,620

There we go to negative value on the cube where we're not all perfect.



93

00:07:21,620 --> 00:07:22,950

All right.



94

00:07:23,480 --> 00:07:27,040

So goes the negative value and then the positive goes to a positive value.



95

00:07:27,260 --> 00:07:31,650

Pretty awesome so now I'm on frame 30 I could go to a negative value hit.



96

00:07:31,670 --> 00:07:34,850

I insert the keyframe.



97

00:07:34,970 --> 00:07:36,750

And now we have this.



98

00:07:36,770 --> 00:07:42,590

If I hit Altay up eight to play that is our animation of our shape keys.



99

00:07:42,710 --> 00:07:47,670

We could also increase the maximum value let's say to 10.



100

00:07:47,690 --> 00:07:52,410

So now you could bring your spikes even further out.



101

00:07:52,430 --> 00:07:53,770

How awesome is that.



102

00:07:53,960 --> 00:07:57,620

So again shape keys are really really cool.



103

00:07:57,710 --> 00:08:03,530

Just like with the other one you could actually copy and move them with this little option menu that



104

00:08:03,530 --> 00:08:04,440

we have here.



105

00:08:04,520 --> 00:08:07,790

We have different options here from mirroring the shape key.



106

00:08:07,910 --> 00:08:10,590

And you know moving it to the top or the bottom.



107

00:08:10,770 --> 00:08:13,350

And we could probably we might take a look at that later.



108

00:08:13,520 --> 00:08:15,370

But these are the main options here.



109

00:08:15,380 --> 00:08:19,120

The plus and minus sign to add or to take away shape key.



110

00:08:19,220 --> 00:08:20,780

The value here.



111

00:08:21,140 --> 00:08:27,260

And then the range of minimum and maximum are the main options that you're going to be using for the



112

00:08:27,260 --> 00:08:28,270

shape keys.



113

00:08:28,280 --> 00:08:30,290

So really really cool.



114

00:08:30,380 --> 00:08:36,470

And again the basis is how your shape looks in its original position.



115

00:08:36,470 --> 00:08:38,780

So once again those are shape keys.



116

00:08:38,930 --> 00:08:48,500

And let's go ahead and now use shape keys with our lattice modifier in order to make our ball look like



117

00:08:48,500 --> 00:08:50,190

it's squashing and stretching.



118

00:08:50,210 --> 00:08:50,660

All right.



119

00:08:50,660 --> 00:08:53,710

Let's head over back to our scene see you there.



120

00:08:53,760 --> 00:08:56,250

And you come up with some kind of catchy phrase.



121

00:08:56,510 --> 00:08:58,740

I'll see you there or B.



122

00:08:58,970 --> 00:09:01,600

Now I can say I'll see you there.



123

00:09:02,090 --> 00:09:04,240

And this image is in black and white.



124

00:09:04,250 --> 00:09:06,570

What is happening.



125

00:09:07,080 --> 00:09:09,590

All right I decided throw black and white image in there.



126

00:09:09,590 --> 00:09:15,290

Hopefully that's cool with the belief in oneself is what one needs to start planning into the mind.



127

00:09:15,290 --> 00:09:21,200

The seeds of one's goals that were once just dreams until one day they grow up to things that can be



128

00:09:21,200 --> 00:09:25,020

seen Believe in yourself and in your dreams.



129

00:09:25,040 --> 00:09:30,680

Ladies and gentlemen start planning that seed of belief into your mind for your 3-D arts and for anything



130

00:09:30,680 --> 00:09:32,400

else in life as well.



131

00:09:32,400 --> 00:09:33,550

I'll see you in the next video.



132

00:09:33,620 --> 00:09:34,220

Oh wow.



133

00:09:34,260 --> 00:09:36,430

Appreciate you all as always.
