All language subtitles for 36 - Blender Overview Pt 2

Ok so before we Delve

Any deeper into the basics of blender I just wanted to do a really quick overview

Set up light to 3D graphics

For those of you who have maybe never worked with 3D graphics or just want to understand it on a little deeper

I'm a level

Now

Everything that we've been doing

In Andrea and blender after this point has all been in 3D and so far it has

Largely pretty into it

And that is because we perceive reality in three dimensions

Now what this means is that every point in the universe can be mathematically described using a 3

System

Which we did not with x y and z values

Now you just should be so much familiar to you from the work we have done already in unreal using

Things like the X the Y and Z values for location and location

Blender it is no

So here we have our default queue for instance

A a location of 000 in rotation of 000

In a scale of 1-in all

In all directions now in blender

The xx

Access is represented by the

Redline here and basically describes the

Generate movement

As

Any object in our scene

By is denoted by the green access here

Represent

Forward and backward in Arsene

And the z-axis

What is the up-and-down access and it is represented by this blue line in our scene

These colours are the exact same as they are and the real

So this should be again someone familiar

Now there is one small cardiac here in that some

Some 3D programs represent being forward and the wires being up

And in those cases you just have to know the orientation of the program

That you're in

Eventually going to be using this object for

And you may have to rotate your object by 90 degrees to get them to appear correctly in

Does progress

Tell ever blender has the same orientation as unreal

So we are all set and ready to go there

Now

3D computer graphics are representations of 3D objects that are drawn

Render onto a 2D screen

The screen of course being your computer monitor

So what 3D rendering software such as a blender or unreal Engine

What is due is that they take the mathematical information that describes each of these

They've render them onto this 2D surface

Using the principles of perspective

The weather brain stop receiving has been through dementia

That is why I will leave you three objects in the 3D viewport we are using them

In perspective

Now

All the objects we create in blender for this project are going to be known as mesh objects

A message object at it's most basic level is a collection of points in 3D space

As described by the X Y and Z value

These points

Are cold

The 3D rendering package your using in this case of Wonder

Will take

Information on the individual points

And it will dry

Between

To further define the shape

Now the combination of vertices

And

How does that make up your matter what is known as a wireframe

Which we can view

Like this

From this point

Faces or sometimes they're called polygon

Will be drawn in between these edges to give the object its solid appearance

There for a metal object is simply a digital representation of a 3

It is composed of

Edges and faces

Play the fool make more sense as we start to work with the

Ok

So when you start up one day you will be in what is called object noun

An object mode

Basically is

The level of Linda which allows us to work

With individual objects on on a whole object level so when I have this cube here

And I move it

I'm moving the entire cube

Now to add a new object

Into blender all we have to do is press to shift and a to bring up this Adam

And don't worry about anything down here for now I would want to focus on at this point is adding me

Gnashers

So we have a cube to start with but we can add all sorts of shapes here

What is the plane aspheric on in so on all the basic 3D shapes that you could require

Set a fire alarm

2

The scene is going to add

At the world origin which is 000 all these axes collide

And you can see that when I select it is a separate and distinct object

From.sd 4qq

Now if I need to delete any objects from the sea

I can simply say like it here or in the hierarchy can see that my phone has been added to the hierarchy as well

Any omelette from I seen that I do not wish to have

In simply press the delete key

To get rid of

Alternatively you can also select any on getting your seen in

Excuse

Depart the delete menu

And that will delete it as well

Now

Want to talk about how to transform on Jack

In the viewport

Now

We transform objects in unreal Engine before so the concept is

Should be fine

Transforming just as a reminder is

Succinct way of describing

The values of location rotation and scale for any object in your

Changing any of these values

Is cold transforming the

Now in unreal Engine 5 the transform keys are based on their location on the keyboard

So we had w for move

We had E4 rotating R4 scale because those keys are all right next to each other

On a typical corgi keyboard

However things going to work a little bit differently in blender

Are the trains from hotkeys in blender are based on the name of the operation

So to move something in blender

Bring up the G key for g

And if we press the G key and move arm else around

We can see it moving through of uniformly across

3D space

To drop

Or cancel this movement we just want to escape

Or right click will also

Cancel the operation

2

Place

Anything in a new

Ask location we just want to press TV programme

No matter where we want it and then left click to drop

To rotate an object in blender

Revenue vrt for rotate

Sophie

Are we moving house we can see it rotating on all axes here

And similarly if we wanted to scale any object in wonder why you would select

Ask for scale

Tell One More Time those

Hockeys RG4 grab

Arthur Road

Astroscale

We can always and do all of the operations by pressing ctrl and z

Now transforms

Can be performed in a number of different ways

We can perform a transformer operation uniformly meaning across all three acts

Is that once

So if we were to select this cube and process

If we look right here

As we perform the operation we can see that we are scaling this queue we uniformly across all Direction

They can also be performed non-uniformly

By following the trains from hockey with the key of the axis you wish to transform

So for example pressing on your keyboard and then x

Will scale

The mesh of long The xx

Or for another example person G for grab and z

I will transform it will grab this mash and move it along

Does he

Glassware we can perform in a transform operations is numerically

What this means is that we're going to follow the transform

And or Access keys with the numerical value

Sell for example

If I select this Cuban press are

Then Z then type of 45

I can rotate this cube

Excuse me or round the z-axis by 45 degrees

Or something like G and then why and let's say negative turned

-10

Forward along

The y-axis here

Of course all of these

Numerical values are in a reference to world space which is denoted by this great here

And the rotation values are in degrees meaning that 360

As a numerical value would

The equivalent to 0

So there is no rotation between 360

You can also type in these values manually here under the transform

Peril

Which is in the property

Window

And if the object properties tab within that one

Play clear the transforms I've made

The way that I do this say I have something Transformed

And I want to just get it back at the default I'm going to use the alt key plus V transform hockey

To clear this value so if you look at these values here

What's a location if I wanted to clear the location of this object I would select it in the view

Assault in g

And that would snap all these values at back to zero

In this works with any of the

It's so

I would press old and are to clear the rotation and alt and AST to clear the scale

So that is the basic cell transforming in object mode however

Transforming primitive around is not going to be sufficient for what we were

To create in wonder

So we can change the shape of these objects in more advanced ways as well as a

Remove points

By pressing the tab key to enter edit

You could also access at an object not being

Strapped down on the top

Corner

The screen

And we can just like the strap down we have and we have it now

Then we have some of those here that we're going to get to you later but for now it's just look at object

Stop pressing tab

Will Travel

In out of adjective elephant's oh that's good edit mode

And from edit mode

From here we can see we can select individual vertices

Bye

Having the Vertex selection and active which is denoted by this iconic here this Dad

You can't get rid of fleas

If we change to absolute mode

Which is

I can't wait

We can see

And if we change to face so we can see

Faces here

Now of course

All of these selections and

Of course lighting all these

We can still use our

Standard transport tool so if I wanted to

Rab this point and move it down

Selected in Edmonton G and n z and grab Justice point out

And already you see I have a more complex shape than I was able to get in on treadmill

Of course we can select more than one point at a time by holding the shift key so making our first selection

All my shift key making a second one and now I can use any of the transform operations that we do

To change this edge how are you like so if I would say scale it long as he

I can bring it in Lakeside

To select everything

Within a single object are we have to do is press on a keyboard

For all

Did you say everything we just have to click somewhere off of our object

What's a we wanted to

Continue to refine the shape by adding some more points to it this is

Already becoming more complex shaped and we had previously but

In order to further development for going to need some more vertices here

In order to refine the shape

There's a couple ways

There's a couple of basic ways to add more points to our mesh

Now the first one is going to be to subdivide

The way that we can some divide is by making a selection

On I'm I'm going to sleep for this entire face

We can right click

And then the first menu option here is subdivide

So what we get here if you go back into vortex select mode

If you can see that it has

Divided

This face evenly

Into four smiley faces and that is how we send it

We can also subdivide edges

By selecting the edge

Either it

Turn off using the abstract noun or by shifts lightning and both points that make up the edge

And we can make like any tips and divide again to put a single point

Edward we don't come in if you

Another very common way to add points to a mesh is to use

The internet loop funk

Now to do this for going to hit ctrl and R on the keyboard

Which will give us Israel preview yellow ring that goes around

Your mash

In

Different directions depending on where you place your cursor

What's a I wanted to basically add in Edge loop around

Play nice horizontally what I would place my cursor

It was quick

And then from here I have one of the slide function

So now I can either

Slider to where I wanna and clip to place it

Or if I wanted to divide this exactly and half

What I can do a take control order bring up that preview again

Quick

Think I can get without moving the without moving and I said all will exactly and then

Or if you control our

Quick and then right click

What's a u

Accidentally

You wanted it directly in the middle that you've accidentally removed your mouth

And you don't know how to get it

Back exactly what you could just right click and it will drop that cut

Directly in the middle

Now there are lots of more ways to add

Points but we will cover them at Morley

Don't let the most basic way

How to delete a point

All we have to do is select the point that we wish to do

And proceed delete key or we could press the excuse

In either of these options will bring up the same delete menu

From here you need to select

How you would like to delete what you're a select

So if I

We have two options Theory how the delay

Functions right here

Can we have the dissolve functions right here so if I were to say

Single Vertex

Press x to bring up my delete menu

And delete any vertices I have selected

This will remove the point

And anything that is dependant on that point as well so because I deleted

That individual Vertex

Everything every face and Edge that was

Dependant on that very takes being there

Is now deleted as well and I have a sort of hole in my mash

Control Z that and do that

The second weekend delete something

Is basing the dissolve functionality so if I press x in I try to dissolve this photo

What you see we've gotten here it is that it has removed the selected point but it has tried to return

Get me underline geometry

So the point is that you see there is no longer hole in the match and it hasn't said try to draw this

Over the remaining vertices

As I said there are more advanced mesh modelling functions

But we will cover them as they are used for this project I just want to give you it's one of an overview

The basics on how we manipulate

Mesh objects
