00:00:06,230 --> 00:00:10,670

All right now let's take a look at how to edit arm mash.



2

00:00:10,670 --> 00:00:12,820

This is where the fun begins.



3

00:00:12,830 --> 00:00:14,360

So the way to do that.



4

00:00:14,390 --> 00:00:20,600

And before I want to do that actually let's over here at the top you can see blender render.



5

00:00:20,870 --> 00:00:29,630

And this is basically the old way of rendering or compositing or putting together your images so there's



6

00:00:29,660 --> 00:00:37,670

a certain you know algorithm of how the lighting and how the image will look like in your final render.



7

00:00:37,670 --> 00:00:42,440

And this one is a little bit outdated So let's switch it to cycle's renderer and you can see some of



8

00:00:42,440 --> 00:00:43,360

the options change.



9

00:00:43,370 --> 00:00:50,900

But for the most part everything is the same but it looks a lot better because it has new updated features



10

00:00:50,990 --> 00:00:58,760

of how the lighting interacts with objects how the materials look and what you can do with the materials.



11

00:00:58,760 --> 00:01:00,110

It's more realistic.



12

00:01:00,120 --> 00:01:01,350

Let's just put it that way.



13

00:01:01,430 --> 00:01:04,200

It gives a much more realistic on your final render.



14

00:01:04,220 --> 00:01:10,030

Now what effect anything that we've done so far so by just want to make sure to switch it to that now



15

00:01:10,040 --> 00:01:12,060

to edit our object.



16

00:01:12,290 --> 00:01:13,560

What is editing.



17

00:01:13,580 --> 00:01:15,860

Well first of all let's hit shift tab.



18

00:01:15,980 --> 00:01:20,640

If you haven't already closed that and the T key to close that as well.



19

00:01:20,660 --> 00:01:26,480

Now right here you can see that we have our cube and if we grab it or rotate or scale it we're rotating



20

00:01:26,480 --> 00:01:30,560

and scaling and grabbing the object itself.



21

00:01:30,560 --> 00:01:35,190

You know we're we're not manipulating how it looks at all.



22

00:01:35,210 --> 00:01:46,640

So if we go down here from object mode and switch it to edit mode or shortcut key it's tab which toggles



23

00:01:46,640 --> 00:01:48,810

in and out of edit an object mode.



24

00:01:48,980 --> 00:01:56,760

You can see that now we actually have you know different points on the cube that we can edit and change



25

00:01:57,060 --> 00:01:59,500

which is rather interesting.



26

00:01:59,580 --> 00:02:07,500

It's actually made up of several different its composite It was several different parts a mesh that



27

00:02:07,550 --> 00:02:12,590

has vertices which are these little endpoints right here these little dots.



28

00:02:12,930 --> 00:02:18,900

And you can see that by going down here to this little panel right here you can see that right now we're



29

00:02:18,900 --> 00:02:21,750

in Virtex select mode.



30

00:02:21,820 --> 00:02:30,430

The other option is edge select mode so if we select this you can now select edges of your mesh and



31

00:02:30,430 --> 00:02:36,460

to select multiples all you do is hold shift and you could like multiple.



32

00:02:36,460 --> 00:02:43,780

The next one is the face select mode where you as you guessed it you could select faces of your mesh.



33

00:02:43,870 --> 00:02:45,550

So pretty awesome.



34

00:02:45,730 --> 00:02:54,980

And so geometries and meshes are composed of Usually those three things Berta's sees edges and faces.



35

00:02:54,980 --> 00:03:01,630

Now a shortcut key to access this little Monterey year is just like tabus to go in and out of object



36

00:03:01,630 --> 00:03:02,470

or edit mode.



37

00:03:02,650 --> 00:03:07,280

When you're in edit mode if you hit control tab it will give you this low menu.



38

00:03:07,990 --> 00:03:12,270

Now just like the other things and let me go over this first.



39

00:03:12,310 --> 00:03:19,720

So vertex is a single point and a vertex can be on its own if need be.



40

00:03:19,930 --> 00:03:28,360

For example if we had shift D which is to duplicate with this vertex selected you can see that.



41

00:03:28,460 --> 00:03:35,990

Now I have a vertex out here and a vertex can exist by itself which you usually never do this but I'm



42

00:03:35,990 --> 00:03:38,670

just pointing it out I could be by itself.



43

00:03:39,130 --> 00:03:43,790

Let's delete that now an edge right here.



44

00:03:44,670 --> 00:03:47,790

Is two vertices minimum of two vertices together.



45

00:03:47,790 --> 00:03:55,340

So if I hit shift d to duplicate it you can see that if I hit control tab and go to vertex select mode



46

00:03:56,110 --> 00:04:02,340

it's two vertices joined by one geometry or line between them two.



47

00:04:02,370 --> 00:04:07,800

So that's what consists of an edge because go ahead and delete that.



48

00:04:08,340 --> 00:04:16,220

And now a face such as Ray here is a minimum of three vertices.



49

00:04:16,340 --> 00:04:23,530

Because right here you actually asked for and keep this in mind as well when you're modeling you want



50

00:04:24,370 --> 00:04:32,240

things to be squared off you want usually for verdicts for every face that you have because that's when



51

00:04:32,240 --> 00:04:33,970

it keeps it nice and neat.



52

00:04:33,980 --> 00:04:43,340

Even for sculptures or meshes or modeling such as humans the face is basically made up of a lot of tiny



53

00:04:43,610 --> 00:04:44,550

squares.



54

00:04:44,570 --> 00:04:50,670

So four point four sided or four vertex shapes.



55

00:04:50,720 --> 00:04:52,020

It's made up of those.



56

00:04:52,310 --> 00:05:01,490

If you have more vertices than four in a face it can add a lot of problems or cause a lot of trouble



57

00:05:01,670 --> 00:05:03,490

or if you have less.



58

00:05:03,500 --> 00:05:12,610

So again the reason I say three vertices is the minimum you need for a face is because if I select this



59

00:05:12,880 --> 00:05:19,020

and hit shift d to again duplicate it move it out.



60

00:05:19,150 --> 00:05:24,670

If I go to vertex select mode control tab vertex select the vertex right here.



61

00:05:25,470 --> 00:05:33,350

You can see that if I hit three on the numpad on the side view and if we hit E which is to extrude which



62

00:05:33,350 --> 00:05:35,220

I'll go into Llobet after.



63

00:05:35,350 --> 00:05:36,630

I just want to show you here.



64

00:05:36,750 --> 00:05:42,050

Extruding with Iike here will basically pull it out.



65

00:05:42,140 --> 00:05:50,480

And now if we select this one we shift right click this one shift right click this one and then we hit



66

00:05:50,540 --> 00:05:57,700

F which will fill in that face you can see that we now have a face on here.



67

00:05:57,740 --> 00:06:02,630

If I control tab and go to face life mode you can see that we have a face.



68

00:06:02,630 --> 00:06:11,210

So again a face is made up of a minimum of three vertices an edge is made up of minimum of two vertices



69

00:06:11,960 --> 00:06:17,930

are actually usually only has two verses because then it would be another edge such as here and a vertex



70

00:06:18,020 --> 00:06:20,690

is just a single point on a mesh.



71

00:06:20,990 --> 00:06:26,260

And keep in mind that correct geometry are correct modeling.



72

00:06:26,480 --> 00:06:35,370

You usually you usually do not want to have triangles and you usually do not want to have something



73

00:06:35,370 --> 00:06:39,110

that has more than four vertices.



74

00:06:39,210 --> 00:06:41,170

If you can prevent it.



75

00:06:41,370 --> 00:06:49,080

So keep in mind rule of thumb that for vertices for every face is what you want to aim for.



76

00:06:49,080 --> 00:06:54,480

If you are if you're absolutely nybble to and you have to have a triangle which at some points you will



77

00:06:54,480 --> 00:06:58,350

have to or have to have one with more vertices and four.



78

00:06:58,650 --> 00:07:00,470

OK and then that's the exception.



79

00:07:00,480 --> 00:07:08,070

But 90 97 percent 95 percent of the time all your geometry and all your meshes are going to be made



80

00:07:08,070 --> 00:07:16,920

up of four faces four vertices and just a lot of these combining together to form something even even



81

00:07:16,920 --> 00:07:20,030

natural looking objects like animals or humans.



82

00:07:20,030 --> 00:07:23,790

It will be made up of four bird seed faces.



83

00:07:23,820 --> 00:07:27,210

All right so that's basically what meshes composed of.



84

00:07:27,210 --> 00:07:31,370

They're composed of vertices edges and faces.



85

00:07:33,760 --> 00:07:39,730

All right so our low quote for the end of this video is actually a poem that I wrote so some are quotes



86

00:07:39,760 --> 00:07:41,910

and some are poems that I write.



87

00:07:42,070 --> 00:07:48,970

This one is a poem so I hope you enjoy inspiration without perspiration is the beginning of delusion.



88

00:07:48,970 --> 00:07:53,290

One can hope one can wish but then one creates an illusion.



89

00:07:53,320 --> 00:07:58,630

So take your spirit faith and desire and start the work and perspire.



90

00:07:58,900 --> 00:08:02,670

So Faith inspiration without action is dead.



91

00:08:02,800 --> 00:08:08,470

So take the action take that inspiration and start putting in some action toward your dreams towards



92

00:08:08,470 --> 00:08:10,400

your goals and towards your 3D arts.



93

00:08:10,420 --> 00:08:11,620

I'll see you in the next video.



94

00:08:11,620 --> 00:08:12,720

Ciao for now.
