00:00that the SHIFTs make and undo parentheses.
00:05Now, we made the parenthesis with CTRL P to undo ALT P.
00:12Okay?
00:13Only if you ever need it, just to have that notion.
00:24And with this, we have a car made very quickly.
00:30Quite similar to what you have here.
00:33And it took us, I don't know, we are here with 30 minutes of work.
00:38Very, very slow to explain.
00:40Okay?
00:42On top of this, you will now want to make small variations.
00:48Do you want other cars?
00:50Let's see what happens if we now duplicate.
00:56Select Hierarchy.
01:00I can now duplicate.
01:051, 2, 3, 4, 1st.
01:09They are all the same color.
01:13Maybe I can get here, in this second car,
01:16and change the color to red.
01:20Ah, they all turned red.
01:24Why?
01:25For the same reason of duplication or instantiation.
01:30The materials are instantiated, that is, they are clones.
01:34Notice that my material, car color,
01:41has 4 users here, are you seeing?
01:44This 4 means that there are 4 cars using this same material.
01:50It's the same.
01:52If I want this blue car,
01:55the first thing I have to do is break this instantiation.
02:00How do I do that?
02:02We have already seen that this is the number of users.
02:06If I click on the number,
02:09this is now the car color 001.
02:11It is no longer the same car color as this one.
02:15This one has the car color.
02:17This one has the car color 001.
02:19And it only has 1 user.
02:21Notice that the other car color now has only 3.
02:26Which means that this one already has an independent color.
02:33Ok?
02:36There are other ways to do this,
02:38but this one, for now, is the easiest.
02:42Ah, I want this one to be green.
02:45I isolate the material, make it unique,
02:48and put the green car.
02:50Ah, and this one wants it to be yellow.
02:56First make it unique,
02:58and then put yellow.
03:06And so it starts to have some variation.
03:08However...
03:11Yes?
03:14No, no, no, no, no, no.
03:15No, no, no, no.
03:17That's it.
03:18But sometimes you will want to fill a city,
03:23and you will not want to make 150 vehicles.
03:26Ok?
03:27Only this already helps that by making 3,
03:29you get to 30,
03:31and all of them half different.
03:33Now, if we really want different vehicles,
03:38what can we do from here?
03:41Well, let's invent.
03:43Once again.
03:48Select Hierarchy,
03:49because I now have objects inside objects,
03:52I will select them,
03:53and here it is faster,
03:55instead of going around here to select the wheels.
03:57Shift H.
03:59I hid all the others.
04:01And let's transform this into anything else.
04:04This will be the cabriolet version.
04:08Ok?
04:10That is,
04:12it is uncapable,
04:13and has no rear seat.
04:16Here.
04:17More.
04:19More.
04:20This.
04:21Erase.
04:23This.
04:24Erase.
04:25This.
04:26Erase.
04:41And it will be more racing.
04:45Let's go here to the vertices,
04:48and let's make a side view.
04:56Grab in Z,
04:58comes down here.
04:59Grab in Y,
05:01X,
05:02comes more here.
05:08Grab in Z,
05:10comes more down.
05:12Grab in X,
05:14comes more.
05:16Let's see what we can do here,
05:18for this to be a little more sporty.
05:23This.
05:25This.
05:27I already know what I'm going to do.
05:29Two cuts here.
05:45Just like that it's already different, notice.
05:48And the back too.
05:50This.
06:11I have to take into account the vertices.
06:20This.
06:32Okay.
06:35Obviously it's a bit strange to have uncapable cars,
06:38when we don't have people inside, right?
06:43But for the effect, it works.
06:46Next we do here, for example,
06:48the ice cream truck, or a cargo truck.
06:52Just to see that very quickly,
06:55suddenly, this is a car.
06:57Shift H to show everyone else.
07:04Alt H, not Shift H.
07:07Okay.
07:08And I have this.
07:09And now I'm going to take the green.
07:11Select.
07:14Select Hierarchy.
07:16Shift H.
07:18And the green will be the cargo truck version, for example.
07:23Okay.
07:24This glass.
07:26This glass.
07:28And this glass I'm going to erase.
07:30But instead of erasing, I'm going to do something else here.
07:36Delete Edge Loops.
07:39X.
07:40Notice that this is canceling the operation I had of the inset.
07:46And I went back to the original version, before doing the inset.
07:50I removed the whole loop.
07:52Okay.
07:54I did Delete and Edge Loop.
07:59Instead of erasing and making a hole in the geometry,
08:02I went to the last option.
08:05With this,
08:07I can now
08:10notice.
08:11Take this.
08:15What I did was Delete Edge Loops.
08:19Delete Edge Loops.
08:24And all this,
08:26Scale X to 0.
08:30Grab in X.
08:35And it becomes green.
08:41Cargo Truck Version.
08:46Ah!
08:47But now,
08:48we're going to change the wheels.
08:52Yes.
08:53So as not to get a longer cart.
08:55It's class 2.
08:56And what determines the class of the cars is the distance between the axles.
08:59I don't know if you know.
09:01So,
09:02we're going to increase the distance between the axles.
09:06Grab in X.
09:12And we're going to grab
09:19the wheels.
09:25I just
09:28don't want to move this axis here.
09:33Where is it?
09:37Even here in the middle.
09:45In this case, it's easier to do like this.
09:47Remove the transparency.
09:55And be careful.
09:56Let's do this only to the Grab truck in X.
10:00And I have to move this back here.
10:02And I'm going to see a distance.
10:041.
10:05Minus.
10:07Why?
10:08Because I can't move the wheels in edit mode.
10:11Otherwise, I'm moving the back and the front.
10:13Because they are columns.
10:14They also go.
10:15These have to go.
10:16Grab in X.
10:18Minus.
10:20Okay.
10:21And now I have my cart.
10:26Made from the same object.
10:30Of course, now I could also create some more changes.
10:36And put, for example, only the rear wheels.
10:44Inset individual.
10:46Extrude.
10:48Create rear lights.
10:50Create ...
10:51Make some variations here.
10:54Alt H.
10:56This already starts to count as three vehicles.
11:00And we did it very quickly.
11:02After choosing an aesthetic for ours.
11:05You know.
11:06Do you want a police car?
11:07You have to add the sirens.
11:10Do you want an ambulance?
11:11Yes.
11:12It's putting a red cross there and being white.
11:15It will depend a little bit on what you are doing.
11:21So far.
11:22We worked.
11:24Our geometry.
11:27As.
11:29The raw material for me to change.
11:31I want to do something.
11:33And.
11:34I will edit the vertices and the edges of the geometry.
11:38However, we have a colleague here who works with 3ds Max.
11:41Right?
11:44The logic of work of 3ds Max is another.
11:48Instead of manipulating vertices, edges and faces.
11:51Often what is done in other softwares is.
11:56Create modifiers that alter my base geometry.
12:03Blender also has the possibility of working with modifiers.
12:10And we will use them to do many other things.
12:14But I will show you now where they are.
12:19I'm going to make a small mistake here.
12:25I think it needs to be reformed.
12:27Let me see if I have another one here.
12:29I'm going to stop the recording of the car here.
12:31Not to make a video too long.
12:33Since I'm going to get into another subject.
12:37Yes?
12:40In Moodle.
12:41Okay?
12:43The place of all things.
12:48Well.
12:50Let's get here.
12:53In our convertible car.
12:56And I'm going to duplicate in this case.
13:01Control.
13:04J.
13:05I put everything together in a wheel and everything.
13:07Just to show you now.
13:10Imagine that.
13:13Your scene.
13:16It takes place.
13:20In Porto Marítimo de Sines.
13:23Where a loader just arrived.
13:26From Toyota.
13:27Coming directly from Japan.
13:30And brings 600 of these cars.
13:33And they are all parked in the park.
13:35Because they unloaded from the ship.
13:37And they are all lined up in rows of 10.
13:41For 60.
13:45Okay?
13:50This parking.
13:52Of course, with what you already know.
13:59You could duplicate this car.
14:02Shift D.
14:04In X.
14:0710 times here.
14:10And then.
14:11Duplicate this.
14:12Shift D.
14:13In Y.
14:1660 times here.
14:18Right?
14:19We already know how to do this.
14:21But, as I have already told you several times.
14:24The Blender is a tool for lazy people.
14:27Therefore, there are easier ways than duplicating, duplicating, duplicating.
14:32Until the end of existence.
14:34Even because duplicating creates additional geometry.
14:39And I don't always want it.
14:42Here in the Fender key.
14:44Do you know Fenders?
14:45Don't you know Bukas?
14:48You have the possibility to add modifiers.
14:53To your geometry.
14:56And it has several types of modifiers.
14:58We are not going to cover them all now.
15:00From afar.
15:02We are more concerned with the generation of content.
15:05So let's focus more.
15:07On these that say Generation.
15:10That allow me, from a geometry.
15:13Generate.
15:14More.
15:15Or.
15:17Generate.
15:20More or different.
15:22Ok?
15:23And let's just look at the first.
15:25Array.
15:27And notice how.
15:29Very easily.
15:33You can do.
15:3510 duplicates of this car.
15:40And 10 duplicates.
15:42Or 60.
15:44Duplicates.
15:46Of the same duplicate.
15:53Ok.
15:54This looks more like the Volkswagen factory.
15:57There in Palmela.
15:58Ok?
16:01And suddenly.
16:03I can have.
16:04A lot.
16:06With very little work.
16:09Ok?
16:10What do I have here?
16:11The Array of the Array.
16:13An Array makes 10.
16:15And passes the content of those 10.
16:17To the next Array.
16:19That does.
16:20To the side.
16:23And this starts to be very useful.
16:26To do small things.
16:28As simple as.
16:30A fence.
16:32Imagine that you have.
16:34A fence.
16:35Ok?
16:36After all.
16:37Your scene does not happen.
16:38In Porto de Sines.
16:40Nor in Palmela.
16:43Delete.
16:45After all.
16:46This happens.
16:48In a simpler place.
16:56And I'm going to do something here.
16:58Very, very rudimentary.
17:00Just for you to see.
17:03Cut.
17:05This Scale.
17:07In Y.
17:11Cut here.
17:13And each of these.
17:21Inset Individual.
17:26Extrude in Y.
17:28Scale in Y.
17:32Scale in Y.
17:36And now.
17:38I'm going to do a little trick here.
17:48And my little trick will be.
17:50I will direct them.
17:53Scale Y.
17:55Zero.
17:59And this.
18:01Scale Y.
18:03Zero.
18:07How?
18:11Because it is much more difficult.
18:13Having done that by eye.
18:15To get that right.
18:17Scale to zero.
18:19It is perfectly aligned.
18:22Rotation.
18:24I had to know how many degrees I was going to rotate.
18:26And I had to do that by eye.
18:28And I could not align correctly.
18:30And for what I want.
18:32Alignment is essential.
18:34Because notice.
18:36Now I'm going to get here.
18:38And I'm going to do the same Array.
18:40In this case.
18:42Along the green line.
18:44So in Y.
18:47And it starts to have.
18:49A circle.
19:01The size you want.
19:08Ok?
19:17If I can think.
19:19The module.
19:22The repetition.
19:24It's easy.
19:30Doubts so far?
19:41It's down there.
19:43Where he chose.
19:45To get.
19:47In your case.
19:49If it is ahead.
19:51In Y.
19:53This value advances.
19:551.2
19:57And this goes to zero.
20:01Yes.
20:03Which is great.
20:05To make a traffic line.
20:07Ok?
20:09In bottle.
20:11Three rows to the side.
20:13Three rows to the front.
20:15And never again.
20:17Of course they would all be the same.
20:21But then there are ways to vary them.
20:23Attention.
20:25Well.
20:29These modifiers.
20:31They serve.
20:33And let's just look here at Generate.
20:35For some more.
20:38Array.
20:40We already saw.
20:42Creates duplicates.
20:44Bevel.
20:46We know how to use it in geometry.
20:48It's the same thing.
20:50Only I get parameters.
20:52To move here.
20:54Notice.
20:56I'll look.
20:58Here for my geometry.
21:07And if I apply.
21:09On top of this.
21:11A bevel.
21:13What I'm going to do is round.
21:15Or bevel.
21:17The edges.
21:19As far as I want.
21:21Do here.
21:29Advantage of the modifier.
21:31It is parametric.
21:33That is, I can go changing.
21:35And go back or forward.
21:37Without having to undo the operation.
21:41Or I can hide it.
21:43And see how it looks.
21:45With or without.
21:47If you do not have.
21:49Okay.
21:51Say.
21:57It has.
21:59We have to be careful.
22:01And actually.
22:03These faces.
22:05Sorry.
22:07These faces.
22:09The wrong key.
22:11These faces should not exist.
22:13Because.
22:15If I'm going to glue one thing to another.
22:17I do not need the interiors inside.
22:19And when you remove this.
22:21That gap disappears.
22:23However.
22:25Because it is no longer rounding to that side.
22:27Because it reaches the end.
22:29And has no content to round.
22:31If I had not done this.
22:33The way.
22:35To remove the gap.
22:37It would be to overlap one or the other.
22:39Instead of putting one next to the other.
22:41It was one to enter a little bit in the other.
22:43Also another solution.
22:45More.
22:47Or less well done.
22:49But notice.
22:51I here determine the distance.
22:53That one is on the other.
22:55And it can be useful.
22:57Overlap them enough.
22:59But the correct way.
23:01To solve.
23:03It was.
23:05These faces.
23:07Do not exist.
23:09And so.
23:11The gap does not exist.
23:13It rounds all around.
23:15And it reaches that place.
23:17As it has nothing to round there.
23:19It is a hole.
23:21It does not round.
23:23More doubts?
23:25Your favorite.
23:27Well.
23:29I will not go in there.
23:31Do you know what it is?
23:33Do not you know?
23:35Do you work with Illustrator?
23:37How is it called in Illustrator?
23:39Is it Find Path?
23:41Pathfinder.
23:43Exactly.
23:45They want to cut one way or another.
23:47Problem.
23:49It works so well.
23:51But at the same time.
23:53It will completely destroy.
23:55The clean geometry.
23:57That makes the perfect loop cuts.
23:59Fine?
24:01In practice.
24:03I would leave that.
24:05For a little later.
24:07I'll just show you.
24:09We did.
24:11We had the body of the car here.
24:15And he wanted to make it.
24:17The groove for the wheel.
24:19I can get here.
24:21And say.
24:23Cylinder.
24:35And I want to subtract.
24:37Or make a Pathfinder.
24:41To this cube.
24:43Add modifier.
24:47Boolean.
24:49And I will make the difference.
24:51With this object.
24:53Now I'm going to hide it.
24:55For you to see the result.
24:57It does.
24:59But.
25:01I would keep this.
25:03For when you have a little more practice.
25:05You know it's there.
25:07In the last analysis.
25:09Yes, you can use it.
25:11But.
25:13It is strange.
25:15Because for now.
25:17It is still associated with this.
25:19Modifiers.
25:21Generate.
25:23And it's called Booleans.
25:25Notice.
25:27If I take this one from here.
25:29I'm doing an operation.
25:31That subtracts the intersection of the two.
25:33If I take that.
25:35There will be no intersection.
25:37So it makes sense that there is no hole.
25:39So the only way I would have.
25:41It was.
25:43Apply the modifier.
25:45What does this do?
25:47The modifier disappears.
25:49And the geometry is forever.
25:51Modified.
25:53Okay?
25:55But when you do this.
25:57All that are loop cuts.
25:59Stop working.
26:01You will see.
26:03It goes all around.
26:05Except in the face that was altered.
26:07And from here.
26:09You still have few tools.
26:11To solve the problems.
26:13Later you will learn more.
26:15Build.
26:17Forget it.
26:19It's an animation modifier.
26:21Decimate.
26:23Decimate is interesting.
26:25Because it helps to be low poly.
26:27Let's create.
26:29A tree.
26:31And a tree.
26:33It's a trunk.
26:35And a cup.
26:37Okay?
26:39Let's see what we can do.
26:41I'm going to start my tree.
26:43From a circle.
26:45That would be.
26:47The base of my trunk.
26:49And I will do.
26:51Extrude of this circle.
27:09And up here.
27:11Cursor to selected.
27:13I will add.
27:15A sphere.
27:17Icosphere.
27:29The rudimentary tree in the world.
27:37Too rudimentary.
27:39The trees.
27:41By nature.
27:43They are somewhat random.
27:45And one tree is not the same as the other.
27:47What can I do here?
27:51I will show you.
27:53Another tool.
27:55That is also very useful.
27:57And that actually.
27:59Only alters.
28:01The way we have to work.
28:03But actually.
28:05We will work with those tools.
28:07Grab, Rotate and Scale.
28:09When they do.
28:11Grab from a vertex.
28:13They get in a vertex.
28:15And only he.
28:17It moves.
28:19However.
28:21I can.
28:23Just like in Photoshop.
28:25When I change a pixel.
28:27I just change that pixel.
28:29Or if you want.
28:31I use Feather Selection.
28:33What does Feather do?
28:35It changes the selection.
28:37And instead of changing a pixel.
28:39It also changes those that are around.
28:41Gradually.
28:43Let's turn on.
28:45Gradual selection.
28:47Up here.
28:49Or on the O key.
28:53Which is this symbol.
28:55That is here.
28:57We can turn on.
28:59And notice how now.
29:01The same operation Grab.
29:03It makes all this.
29:05More or less elastic.
29:09And I can.
29:11Change this elasticity.
29:13Changing.
29:17The mouse wheel.
29:25What is important here?
29:29Who had statistics here?
29:31Who passed the statistics?
29:33All.
29:35What do we have there?
29:37Normal distribution.
29:41I knew I was going to kill you at this time.
29:43And that you were going to ask me for a break.
29:47We can change.
29:49The distribution form.
29:53And I can change.
29:55And now I'm going to put it here.
29:57In Random.
29:59If I pull this.
30:01And now.
30:03Pull a vertex.
30:05Suddenly.
30:07I'm creating chaos.
30:09On this surface.
30:13And making all this.
30:15Random.
30:19And this already starts to have.
30:21A little more air.
30:25This Proportional Editing.
30:27It does a lot of things.
30:29It can help you.
30:31To give this air.
30:33And why did I say this?
30:35Because next.
30:37The modifier that was presented.
30:39It was Decimate.
30:41Decimate does the opposite.
30:43Of Subdivide.
30:45Do you remember what Subdivide was?
30:47It cut faces.
30:49In the middle.
30:51And created more faces.
30:53What Decimate does.
30:55Put less faces.
30:57Notice.
30:59I have this one selected.
31:01And I'm going to put a Decimate here.
31:05From there, it does nothing.
31:07Because I'm not decimating anything.
31:09I have 320 faces.
31:11In the tree top.
31:13As I shrink.
31:15Let's see.
31:19If you are working with this look.
31:21Low Poly.
31:23We can reduce even more.
31:25The number of polygons.
31:27Using a Decimate.
