1

00:00:05,810 --> 00:00:10,960

All right now that we took a look at how to subdivide or mash and add more geometry Let's take a look



2

00:00:10,960 --> 00:00:15,710

at another way to do this hitting tab to go into edit mode.



3

00:00:15,960 --> 00:00:22,860

Another way that we could do this because when you subdivide it actually adds geometry everywhere to



4

00:00:22,860 --> 00:00:23,820

the mesh.



5

00:00:24,150 --> 00:00:32,880

And what we want to do here is actually it's called the extrusions so we could extrude or pull out certain



6

00:00:32,880 --> 00:00:35,240

parts of the mesh.



7

00:00:35,700 --> 00:00:43,220

So if I had control tab to go into face like mode and then select a face by right clicking on it if



8

00:00:43,220 --> 00:00:44,680

I hit the key.



9

00:00:45,350 --> 00:00:52,490

You can see that extruder it and brings it out pretty awesome so you can actually start to bring out



10

00:00:52,490 --> 00:00:54,620

parts of your mesh.



11

00:00:56,090 --> 00:01:01,940

And you could do that anywhere that you want you could actually select multiple parts by shift right



12

00:01:01,940 --> 00:01:04,600

clicking and extruding it out.



13

00:01:04,790 --> 00:01:11,130

And this is really cool and adds geometry very fast exactly where you want to add geometry.



14

00:01:11,480 --> 00:01:19,700

Now a thing to keep in mind is as I mentioned previously with the subdividing I do want to go back on



15

00:01:19,700 --> 00:01:28,360

one thing quickly for the subdividing because I guess that most things are for vertices or faces of



16

00:01:28,360 --> 00:01:29,770

four vertices.



17

00:01:30,190 --> 00:01:36,670

If I select this whole thing and hit w and subdivide that's fine because the faces I still have four



18

00:01:36,670 --> 00:01:44,920

vertices on them but if I just select one face and hit w subdivide you can see that these right here



19

00:01:44,920 --> 00:01:56,100

are fine because these have four vertices but this face right here now has five vertices.



20

00:01:56,200 --> 00:02:02,680

So it's a little tricky because now it has and if it's not animated it's usually fine it's usually when



21

00:02:02,680 --> 00:02:07,150

things are animated that you don't want to have this or in other regards as well because it could give



22

00:02:07,150 --> 00:02:09,440

some weird artifacts to the object.



23

00:02:09,520 --> 00:02:15,090

We can see that right here there's five vertices for that one face which is not that good.



24

00:02:15,100 --> 00:02:16,450

It's usually not good.



25

00:02:16,660 --> 00:02:22,810

So keep in mind that when you subdivided you could subdivide individually as well individual faces.



26

00:02:22,830 --> 00:02:25,770

But keep in mind that might not create a good result.



27

00:02:25,990 --> 00:02:28,940

So you usually don't want to do that.



28

00:02:29,110 --> 00:02:35,380

If I control Z to undo all that I now want to show you what you could do with extrusion which is really



29

00:02:35,380 --> 00:02:36,060

cool.



30

00:02:36,400 --> 00:02:42,230

If we select a face and hit eata extrude it automatically brings along this axis.



31

00:02:42,550 --> 00:02:44,880

However left click will confirm.



32

00:02:44,890 --> 00:02:49,850

But if we hit the right mouse button it will actually place it back to the center.



33

00:02:49,860 --> 00:02:55,930

And you think that nothing has happened that nothing has been extruded but it has it's just on top of



34

00:02:55,930 --> 00:02:59,210

the previous mesh that we have before.



35

00:02:59,560 --> 00:03:03,820

If we hit the Eski Now you can see that we're able to scale it.



36

00:03:03,860 --> 00:03:05,880

And how awesome is that.



37

00:03:06,100 --> 00:03:14,620

So we've just created like kind of invert into our face right here and you could see that these faces



38

00:03:14,770 --> 00:03:17,620

still have four vertices each.



39

00:03:17,980 --> 00:03:19,360

And so that is awesome.



40

00:03:19,360 --> 00:03:20,910

It's a proper mesh.



41

00:03:20,920 --> 00:03:23,380

It's still flowing nicely.



42

00:03:23,380 --> 00:03:29,890

So that's another way that you could add faces with the extrusion tool because now you could scale this



43

00:03:29,890 --> 00:03:30,540

down.



44

00:03:31,420 --> 00:03:38,480

And then you could extrude this part out by hitting e you and then if you want to scale it back up you



45

00:03:38,480 --> 00:03:47,600

could hit you to extrude and and so bring it out right click to de-select it as to scale it up and just



46

00:03:47,600 --> 00:03:54,170

bring it forward a little bit and you see that now it's extruded out and it's scaled up and then you



47

00:03:54,170 --> 00:03:57,480

can hit it once again to extrude it.



48

00:03:57,920 --> 00:04:00,650

So that is the extrusion tool.



49

00:04:00,650 --> 00:04:07,440

You could also use the extrude to extrude vertices of single vertices.



50

00:04:07,440 --> 00:04:09,610

So let's do that actually right away.



51

00:04:09,800 --> 00:04:16,280

For hair control have to go on the Virtex like mode I still like this vertex and this one or actually



52

00:04:16,280 --> 00:04:17,250

that would be a face.



53

00:04:17,260 --> 00:04:19,810

So let's just select one of our it would be an edge.



54

00:04:20,000 --> 00:04:26,720

You could also extrude edges of course if I like this edge and hit you to extrude and then Zeeuw to



55

00:04:26,720 --> 00:04:31,300

constrain on the z axis you can see I've extruded an edge now.



56

00:04:31,550 --> 00:04:39,890

Now let's extrude a vertex let's like this one hit enough to extrude and then Z to constraining on the



57

00:04:39,890 --> 00:04:41,670

z axis.



58

00:04:41,730 --> 00:04:43,750

And now we have a vertex.



59

00:04:43,920 --> 00:04:45,210

Pretty awesome.



60

00:04:45,210 --> 00:04:47,950

And just like before we could actually fill in a face.



61

00:04:47,950 --> 00:04:50,490

Let's say for example you want to fill in a face here.



62

00:04:50,640 --> 00:05:00,700

We can do that by just shift right clicking these vertices here and then hitting f fill in that face.



63

00:05:00,880 --> 00:05:03,200

Now we can bring this one down a tiny bit.



64

00:05:03,490 --> 00:05:08,860

So extrusion is super useful and it's very very practical.



65

00:05:08,860 --> 00:05:11,050

There is a lot of different things you can do.



66

00:05:11,050 --> 00:05:17,590

And you know it's a really great tool to add geometry to your mesh without having to subdivide the whole



67

00:05:17,590 --> 00:05:19,120

mesh entirely.



68

00:05:19,150 --> 00:05:24,340

Extrusion is actually one of the most used tools to add geometry to your mesh when you're creating a



69

00:05:24,340 --> 00:05:31,240

human face or an animal or literally any object you're going to be using extrusion probably 90 percent



70

00:05:31,240 --> 00:05:33,340

of the time to add geometry to your mash.



71

00:05:33,340 --> 00:05:38,040

So this is the one that you want to be using because it gives you precision and gives you control.



72

00:05:38,200 --> 00:05:39,920

And you know what you're doing.



73

00:05:40,050 --> 00:05:45,470

Whereas if you select everything and subdivide it lets say you only wanted to add geometry here.



74

00:05:45,520 --> 00:05:48,720

Now you have geometry are added all over your cube.



75

00:05:48,730 --> 00:05:52,670

And like I said all of this here is unnecessary.



76

00:05:52,690 --> 00:05:55,110

You only wanted extra geometry here.



77

00:05:55,420 --> 00:05:58,220

So that is extrude tour.



78

00:05:58,360 --> 00:05:59,320

It's really awesome.



79

00:05:59,320 --> 00:06:06,670

It's fun to use and it gives you some great results to be able to extrude and add different parts to



80

00:06:06,670 --> 00:06:07,410

the mesh.



81

00:06:07,630 --> 00:06:08,240

All right.



82

00:06:09,560 --> 00:06:15,790

And our quote for the end of this video is you have much more potential within.



83

00:06:15,970 --> 00:06:22,760

However in order to tap into that potential you must believe in a reality that is not currently present



84

00:06:23,090 --> 00:06:25,090

which to most is tricky.



85

00:06:25,400 --> 00:06:30,130

You see what you think is reality is only your current perception of the world.



86

00:06:30,290 --> 00:06:33,070

Everyone is experiencing a different reality.



87

00:06:33,290 --> 00:06:38,840

Expand your awareness and you'll see that what you thought was reality was only a drop in the ocean



88

00:06:38,900 --> 00:06:40,820

but not the whole ocean.



89

00:06:40,820 --> 00:06:43,930

There are infinite number of realities that we can choose from.



90

00:06:43,940 --> 00:06:48,550

It's your responsibility to choose one that brings you to where you want to be.



91

00:06:48,950 --> 00:06:53,220

All right you have an infinite number of realities within you.



92

00:06:53,360 --> 00:06:58,110

You have the potential of being an amazing artist or what ever you choose to be.



93

00:06:58,130 --> 00:07:02,150

So just pull out that reality from you and live it every single day.



94

00:07:02,150 --> 00:07:03,270

Appreciate you guys.



95

00:07:03,270 --> 00:07:05,190

I'll see you in the next video.
