Today in class 3, the basic modeling class of Polygon and Nurbs modeling,

we will find out the basic functions using the Polygon and Nurbs modeling

how to use basic figures, spline, subdivision

and Symmetry We will also learn the modeling method

using the spline and pen tools

Also, we will discuss how I’ve designed

the space configuration using the spline

The basic lectures are intended to explain

very specifically and in details for the starters

For the ones who have some level in modeling,

you can speed up the lectures and check if you have any missing points

and find out what you can learn from it

First, let’s explain the fundamental functions from the top

Those who lack basics should follow them one by one

and make this time to lay the foundation

Let’s start from the basic figures

If I may explain, the number in the front is the number of the lecture

and the numbers following that is labeled by the sequence of the class

So, open all the files at once

Click and select in the windows panel and open

Click on the right button, press the dotted line on top and start

I’m going to size up the icon size and see it together

I have them all ready like this

Let’s go to Display and change to Gouraud Shading

We can see the Polygon

Let’s first see from the cube

In the case of the cube, this is the most used

when doing modeling

You can raise up the segments

or you can press Ctrl and when all three yellow buttons are selected

Press ctrl and pull it up to adjust everything at once

Next, you can use Fillet, which the corner part

can be rounded

You can use Subdivision to determine how many curved surfaces

you want to divide

Next, the Corn Let me make it fullscreen by pressing Ctrl + S

Top Radius Bottom, height, and high segment

can be adjustable

and caps is this part

You can change this part like this

Let me expand the Radius in the caps

Then, you can make it into a more circular form

Next is cylinder

Cylinder also have the same functions

The segment have cap parts and object height

and can do it sideways like this

Next is disks

You can expand the inner part of the disk

and cut here using the slice

For plane,

you can manage the segments

For Polygon, I don’t use them all,

but I can use them when you make triangles

and segments can be divided like this

For sphere, you can divide the segments

There are lots of modes in type

We can change the Polygon’s arrangement

We will be using torus a lot

Inner and outer size of the object can be adjusted

, you can also slice it

, slice in the capsule

, and adjust the height of the object

If the height is identical like this

, it may seem like a sphere

Then, for oil tank, the bulged part

can be adjusted, and if you press the cap height,

the bulged part can be adjusted

Youu can also see that you can use slice

like the others

For tube, you can slice it too

and we can control inside and outside parts

For the pyramids, the segments

can be divided into several parts

In case of Platonic,

you can make various polyhedral figures

Next for figure,

we use them a lot when we reference a human size

Here is the height, and when we configure certain scene

We use them when we check the size of the scene

For landscape, we use them when we work on

mountains on the back or making terrains

or making space filled with obstacles

You can adjust the segments like this

If you control the segments, the detail of the terrain can be altered

the ups and downs, other various options can be controlled

Next, is Bezier

In case of bezier, you can make it a point mode in the Bezier

, change the shape, and control how many points you will distribute

by changing the numbers and control the points

to make the figure

Here is the guide The guide also

lets you control different types

and look at sizes as a reference

I hardly use them

, but here was a quick review about the premitive

and basic figures

When we do Polygon modeling, we mostly start from here

and work on the project

Let’s pick the three

and show you a simple modeling

You have to make it editable in order to model

If you want to take a cube and make it editable, select Polygon

and Extrude tool, for example,

if you press D, Extrude comes out

and if you use Extrude, you can make it stick out outwards

Now, I see there is something wrong with the Select tool

I’m going to change everything to 000 and start again

Next, I is the Extrude Inner

You can make Polygon go inwards

Press D again to put it inside

If you tried this and it didn’t go inside like this

, it may mean that Create caps is pressed

In that case, you have to take this out

Okay, so let’s start the modeling real easy

If you press D, it will turn everything in general

So, I’ll turn off the Preserve groups and set it like this

Then, you can do the modeling like this

Press I again to make it go inside

and press D to make it go inwards once more

Polygon modeling means you will be using Extrude

and Inner Extrude so many times

The other one that you will be using a lot is Subdivision

There is a subdivision surface

and if you click on cube and press Alt while clicking on the cube,

it will go in as the parent

Then you can see the objects divided into surfaces

When the surfaces are divided, if you select the cube

and select edge mode or click Polygon,

you can check which Subdivision went in

The Subdivision now divides this one surface into two in the editor

and divide twice again in the renderer

meaning, if this surface is divided, it becomes 4

and 16 again, if you divide once more

, you can see that it gets smoother

So, if the lines get closer and closer, the edge part becomes steeper

and further you go away from the line,

you’ll see this part gets gradual

So, if you increase this value in the Subdivision,

we can get the figure we want

Now, if we were to change this not so gradual,

select cube There is something called KL

KL means to cut It cuts by rotating the loop like this

If the surface is cut by rotating, compared to other surfaces,

you can see this part’s curve is steeper

and more and more you become closer, and the gap becomes narrower

and you can change the modeling like this

The L button, is the loop cut

If you can press Shift, and in here in the middle

, you can cut it accurately and uniformly

, so you should know how to do this too

Now at the subdivision editor, divide 3 times

and three more times in the renderer

, but if this becomes 0, it looks like this here

, but if we render, you can see it is not divided at all

So, if you were to work on some heavy works, lower the Subdivision a little

and see the results like this at the rendering part

We went through the Subdivision a little

Let’s press C and make the Corn

editable and see what comes next

When we select objects like this,

the back part is not selected

In that case, press Space twice, go to options

and try this way

If you turn off Only Select Visible Elements

, the back part is also selected

Of course, we can use something else than Line Selection

such as Rectangle Selection

You can do it like this as well

Next, go to modeling axis

Let’s see how much we want to move the axis in the selected region

I’m going to scroll to the bottom

then press T and size down the scale

We can make this kind of figure so easily

Let’s look at Corn here

I made this Editable, but there is no Fillet

If you want to make it more smooth but with no Fillet,

you can use Subdivision

Yes, you can use Subdivision

, but there are ways without using Subdivision

One of ways to do it is making something called Bevel

Then what is Bevel Double click on edge and select loop

Do UL and select like this or just from the select tool,

and double click and get the selection

If you right click on the mouse, there is something called Bevel

Bevel is a function when you drag the edge and divide them again

Here is Subdivision here again

so you can divide only the Bevel part

So, you don’t always have to use Subdivision

yet add curves in the edge part

with the method I just showed you

We’ve seen how to use Bevel, use Extrude

and how to use cuts

Let me show you once again with a disk

Let me click C and select, there is UL

The UL is something where you select the Polygon in a loop

so you don’t have to do this but press UL and select

Let’s press D and try it like this

, but I have this right now

Let me try it again by setting Preserve Group again

Then, you will have this clean result

So when you make various circular figures

like bolts or nuts, we use disks a lot

So, we can do it like this way

If you check out some of my works, I’ve made before in this method

You can make this shape using Fillet

and make other various design assets

This friend here

also is a fun modeling, let’s find out

Plane, and Q

You can turn on and off all the upper parents

Then, you can see the shapes turn out like this

How do you think I made this

This is by bringing the plane here

Xet the objects as 5, 5

Press C to make it editable

Dlete the ones in the middle like this

This friend here,

put this one up and put Subdivision on top

Then, the results come out like this

Select the Plane again, and press Ctrl + A

to select all, press E, press Create caps

and go like this

Then, you can see the button like shape is complete

Now, if you want to make the edge a little bit closer

, let’s try them by selecting the edge

Select the edges

and press Ctrl to exclude them

then you can scale them down Let’s see

Here is the shape

It doesn’t matter now, but if you want to reduce them not in the y-axis direction

, but only in x and z axis direction

Then click this band and press, this is the shape

You can do the modeling this way too

The next thing you use a lot is Symmetry

This literally means it makes things Symmetry

As you can see here, if you turn off the Symmetry, there is only one object

, but if you turn on the Symmetry, the object is copied

and it becomes symmetric

In the case of Symmetry, depending on the axis you want to copy,

it decides where the objects will be copied

Let's open the Watch file and see Symmetry

It would be nice if we do the modeling together right now

, but the time is a bit too tight

So, I’ll just tell you how it is used, if the Symmetry Subdivision is used

and what are the pros and cons of that function

Look here, select the band part, turn off the Symmetry

Then, you can see that the object is symmetric

with the axis right in the exact middle

Symmetry is used when modeling these

If you turn on the Subdivision, you can use the Subdivision

when selecting a small object

and still do the modification easily

We should be using Subdivision when we want to adjust these curves just a bit

to make the work more efficient

For example, if you take a look at the object on the other side

, there are too many points, so you have to select

so much when you want to change a certain point or a certain region

, and making the modeling more difficult

Of course, you can use the select tool

Press Soft Selection

then depending on the gradation region,

and on the Radius region of the Soft Selection, you can move it more softly

Yet this too, may have so many constrictions

This gets larger circularly, so when moving points in certain regions

, there may be limitations

Let’s turn off Soft Selection

So when you do modeling, doing as simple as you can, using as few Polygons

then making more details after you start

maybe the best way to do the work

In this class, we will be using basic figures

and many works will proceed

So, it would be best if you check out other examples too

Next, let’s see the spline part

Let’s find out what Spline is

We will be looking at the basic shape, excluding the pen tool

and see how these shapes go together with other create tools

to do Nurbs modeling

I am not select all of the functions one by one and find out

, but I recommend you change them all

Especially for those who lack basics,

find out what kind of functions exists

If I were to tell you how to use the functions on the right side,

if there are two or more objects

and you were to select more than two objects, you can add or delete

or combine using those functions

maybe even three

Three objects can be combined like this

, but if the space is different in the Z Depth

that part may come out a bit strange

You should consider these points

and usually, most use them after synchronizing the z axis

There are too many basic spline tools

These are too much, and if we were to go through all of those

it will take too much time so I won’t go through them all

I will tell you the functions

that is used quite a lot in the class

and if you go to the right

, you can see how the shape is made with a spline tool,

combined with other functions

Lets find out about Extrude

open up a clean new window

Let me simply show you

I’m going to open n side

Press Alt and then Extrude, then as you can see,

you can go into Objects, adjust Offset to decide the thickness

and if you go to Caps, you can stack up segments front and back

like you’ve seen them before

and give you a Fillet like effect

and if you go to display, change into Gauraoud Shading(line)

and see what happens

You can see that Bevel goes in

at the front and backside of the edge

and for Lathe, like the icon,

it is suitable for making pot like shapes

If you make it with a pen tool, in the front view

I may have made the shape too roughly

, but if you look here

you can see the pot shape that I’ve told you about

Lathe is used like this

When you look at Loft, there are three white lines

I’m going to use three lines and make something

Here, if you subordinate it below here,

make another one

copy that and make one more, Ctrl, and drag

Make one more to get this shape

click on Loft, go to caps

Turn off the start and end of the cap

Select the circle in the middle and expand

then the shape connects the first and second spline in the middle

The jointed splines are affected

and make a curved shape like this

Now, as you’ve learned in the Subdivision

What would happen if the two splines position so closely like this

You can see that the splines together so close

makes the part steeper

and the Loft here, through Subdivision,

you can touch more details

For the spline mask,

it is a function where there are several objects like this

It combines them together like this

Some of you might wonder, what is the difference between the previous ones

Let’s find out with objects

I’m going to copy 2 and put it up

If I make it Union like this,

the two objects are combined as one

It is combined, so it is hard to move it by selecting only one side of the spline

, but for this function, objects are not baked yet

and makes it very useful when making animation

The next most used function is Sweep

Let me open up a new window

You’ll see a circular figure and white line if you see the icon

Let’s work on it with two splines

I’m going to take Helix and put it down here

The star is too big I’m going to press T and size down a little bit

Now you'll see the helix has loops

The loop has a star cross section

Of course, you can adjust the size when you go into details

Make a rotation or twists

I’m just showing that there are these parts

There will be a chance where I show you other examples

the Vectorizer,

this is a function that changes some images into splines

Let’s open texture

You can drag like this

Press No here and leave the path, and if you see here

it might not go that much in detail

, but we still can adjust the details a bit

I rarely saw this coming out so clean

I don’t use this so much

, but still unique This is good Well, you can try using this function

I’m just showing you there are these kinds of functions

So, we found out what the splines are

and how to use them

Let’s open a new window and find out about spline pen tool

I’m going to click on the middle button and see it in frontal view

You can make the spline in more various shapes like this

Click, drag, make a handle

and make lots of forms

This here, like as we learned before, we can move

scale, and rotate, to adjust the handle

So, when we manipulate the spline

you can see how consistent the curve is This part

is slightly more curved than the others

In that case, you can expand the scale here like this

Next press the move tool, grab it here

and drag it to adjust the size

Then in front view, press Alt

and rotate, then the camera spins around

The camera rotates and can be fixed by pressing Shift

then if you press Shift and move the handle,

you can adjust only one side of the handle

If you move it with no Shift, both sides will move

so you can apply this to where it steeply turns

You can press Shift and turn

and if you want to add lines additionally,

press Ctrl and do it like this to make a line

So, here is the way to make shapes

Basically, spline has something called Close spline

If this is turned off,

you will see that the shape is opened like this

and there are many things if you check out at the type

You have to decide which type you will be using when working on the spline

Linear will be the selection when making something hard

You can use B spline on some circumstances

You can do this with Bezier too, where in my opinion, you will be working mostly on Bezier

and the adaptive you see here on the side, these parts need to be changed

depending on the situation

The spline’s details are determined by the high or low value of the number

This, we will see a little bit more as we do more works

So, I’ve shown you that you can use spline tool

mostly the Bezier

to make curved shape

but for now, I’ve pressed only one spline

so there are two shapes in one spline

Xo if I do it once more, where the yellow is not selected,

You can see the another spline generated in the side

Assuming you have two in one spline object,

the way to make this two is

the Explode Segment

If you press here, you can see that the two children appear

under the parent

This was a simple explanation about the spline pen tool

Next is the sketch tool

Literally, this is a tool where you can draw

If you higher the smoothing,

you can absolutely make a softer line

Let’s draw one more

If you have something here, use the spline smooth tool

and go around these line

Let's make things a bit complicated

Assuming something like this, flattening these out like this

is the smooth tool

You can adjust strength or Radius here

The fun point about this tool is that if you check random, we are not just smoothing

, but do it in various forms

LLet’s turn the smooth off

if you turn it off and try it this way, you can make various figures

Let’s turn on the smooth once again and organize

You can draw the spline like this, quite interesting

and the Arc tool too I’m going to make a new one for the Arc tool

Assuming there is a spline, the Arc tool

makes this part like that

to adjust the figure

I’m going to select only two and try again

Select two, here it comes again, select two again, and another comes out

and make various figures in this method

You can make various design assets as well

with the stuff you’ve learned in this lecture

If you have tablet PCs, use the sketch function

make a rough sketch, and use a smooth tool

and make organic shape

real fast and quick

I’m going to use Create New Spline

Let’s use smooth again

The principle I use when I do these works is, even if the shapes are different

it still needs to have some consistency

The unity comes from

the level of flexion of this curve

Det the highest flexion level, and if that holds the unity

, the shapes are shown as a group even if there are multiple shapes

and looking like the same design

So, when you work on project

think about the flexion and work

to make a better design outcome

I made it like this and set it in middle

These assets will be used in many works

I’ll show you them later

We can use the shapes we just make

and actually make artworks

There might be ones who haven’t learned Octane

, but let me run the Octane and show you

Octane will be thoroughly discussed more in the Octane lecture

, but it's still okay to think of it as a tour

If you click on the logo here, it renders

and if you bring out the setting, you can see which setting

are being used in the rendering

Let’s put the Octane window at the bottom here at the end

If you put it here at the end, move it side way

and change the layouts

Let’s gather up the stuff we don’t need

Go to Customization, click Save layout as

and type any names you want I’m going to type Octane Coloso

If you save it as Octane Coloso

we can bring out the layouts later on

I’m showing you which rendering is in process

This artwork was easily made

This was made using the shapes we created

Placing these in the right position

is the key to making a beautiful design

If we moved the camera

, you can go back to the previous camera by pressing Ctrl + Shift + Z

If you press Ctrl + Z, the objects

or the animations go undo

So when you moved the camera,

use Ctrl + Shift + Z to move

When working on stuff like this, especially when arranging the shapes

you can get inspiration from other places

For example, go to Pinterest, type Organic Shape

and if you find any shapes you like

I hope you collect them

If you drag to PureRef, the one I’ve told you before,

it brings out the original file in the link

so you can gather many images

Of course, you can collect from Pinterest too

Nature Asset, the ones I’m collecting, if you see here

That's my old picture

If you go to Nature Asset

you can see the shapes that I've gathered

It is nice to go into these places and see the shapes

, but it would be advisable to gather them at one place

to help you work on design projects like artworks

to come back again, when working on this project

I’ll be showing you some of the key points

So, I hope you practice them with the shapes you’ve made

I will be telling you about the Octane and Design

on the Design class and Octane class, but for today

I simply showed you that you could make them using spline shape

and if you got the key points and studied, just apply that

and think you are working and the arrangements and follow my instructions

First, I’m going to make big two shapes and put them front and back

if you see the big shape only, try making one of the big shapes

go pass the object

What I’m saying is, don’t make the object meet at the end of the edge

and make it hard to find out if the object is inside or in front of it

push the outline a little bit like I’m showing you now

Express that the object is in front of the background

slightly forward

and another thing you should consider is the colors

Try making things in similar color groups

For those who haven’t studied Octane

, I’ve made the setup already

so you can take this and try it right away; no adjustments needed

If you go into round, I’ve used round edge

and gave a bit of an embossing feeling

Now it’s gone

If you use too much of the round edge, it will get heavier

, but it is a way to do simple modeling instead of using Bevel

I’ve told you to try the big shape

going over the back of the object’s line

Yhe reason I’m telling you is this

It is nice to show the frontal correlation

, but if you see it here, it will draw attention

towards the line of an object

Especially if there is this curved shape

, if you’re doing this to an object

, putting this here won’t be so bad

, but if you make an object line a little,

much more interesting design is possible

Going back again, the next thing to try is

making little objects

I’m going to divide the small objects into two

as you can see here, the small objects

You can put the front and back correlation of an object at the outline’s region

which lets you see

which is front or back

If you tried the big one, try putting the smaller ones in front

If there are too many blank places, try making balance

and fill it up like this

Other shapes can come in by this line

You can put other shapes and make front back correlations

This shape too

In the case of this color, there is slightly bright blue on the other side

so you can have it on the other side slightly

so you can show the relations using the small objects

and arrange the shapes with the same languages

and balance out the overall level

I will be telling you more details in the design class

I’ll explain to you about design laws and principles

For now, let’s use Extrude on the splines we just made

and add the factors

like lines

Press the button in the middle, go outside the camera

and navigate more easily

The important part here is that you should see

where one of the edges end

In the case of the line here on top,

it shouldn’t be touching the end like this

, but rather show the front-back relations and show

which object is placed front and which is at the back

If you divided the shapes into large surfaces

,you can go add some factors that break the surfaces

If you look at the spline again,

right click the Octane tag, go to Octane tag

If you press it, you can see hair

If you press Render As Hair, you can see the spline

in lines at Octane,

you can adjust the thickness in the Thickness

S,o the ones who lack design skills

practice with the colors shown here

If you want different colors, go to Diffuse

change colors and try various colors

, but if you are not so familiar with colors

try practicing within the same color ranges

or change the watch's color

and make the theme stand out more

At the Octane lecture, I’m going to tell you the basic functions of the Octane minutely

and about Material

Today is just a bonus

These are something I was going to deal it at the back

, but it couldn’t fit in

and there are so many splines included in this

So, I’m going to show you this artwork

and hope you practice the same

how to do lightings of the watch or how to set up the lightings

We will deal this with other class

First, you should try the pen tool with the setup we have now

and apply the shapes that we’ve learned today

to straighten it again, in design,

There is spot, line, and surface in the three elements of modeling

First, make the larger surface

and there are smaller ones that break that surface

then put the other friends that make the surface more diverse

put them once more, and then add the spot like elements

Lines can be added like this too

The specific design will be done on the next lecture

It would be nice to work on the 1:1 ratio works

Usually for Instagram, if you want

to size down a bit, make this friend come inside a bit more

Place this one here, into a triangular formation

and give the image where the objects are dispersed overall

If the ratio changes, the camera lenses value also change

so we need to change the layout again

So, these works that involves various layouts

will be a bit helpful if you practice them more

If you look at an image and all the objects hold one language,

in other words, if it holds somewhat similar curves,

it would be best

I’m also using the end of the curved part and working on it

There is a bit of a stuffy feeling at the bottom where it is overlapped

If you bring it upward slightly, then the lines

form this flow and the middle theme part

shows up a little more interesting

It is quite hard to include spots here

so I’m going to skip this part

, but make this friend a little bit smaller

Let’s change this object’s color

Chang the color like this

I’m going to check once more

Check if there are any objects at the edges

if it ends at the corners like this,

this dislocated part

Is it going to touch the edge

or is it not Quite disturbing

In that case, let’s make the distance a bit more

Make it looks like it is definitely come apart from the edge

Show it's not a mistake

Show that the element is there

to form this kind of lines

So, I’ve just showed you how to make different ratios

I tried cutting the recordings and showing you only one part

, but I thought just showing you all

could be a better help for you

In the case right now, if the angle of the spline is high, the detail is gone

so to make this part seem more soft,

I’ve clicked spline and checked here in the angle to make it like this

The smaller one did disappear

, but here in the logo part is the spot element

that stands out

So, there are no objects close to the edges anymore

There are no cornered objects, and as you can see here

It follows the line, go the object theme part

and come down again. these lines

are embraced by the small objects here

The small objects are placed in the space

in front and back to help easily understand

You should work like this too

Change the colors of your preference when working

and upload it on Instagram as much as you can

So I can check that you all are doing your best

Upload them more, challenge yourself

, and find your own shape on Pinterest or other sites

find it a lot and gather references If you want natural figures,

do natural shapes If you want geometric figures,

you can do geometric shapes But now, the watch itself

is slightly circular shaped so it blends in

with the rounded backgrounds

So, we found out how to use spline

and do the space configuration

We can run the rendering and finish the work

In case of rendering, look at the render setting at the upper part

I\If you go in there, we can adjust

values like size

and to explain to those who have not rendered before

If you go to a render settings like this

, you can choose size and Time frame range in the Output

, but this doesn’t matter because we are in still

You can put it as Current frame

If you check in the save here, a file path is generated

As for me, I am using something called a token

and the render folder for this work is generated

I’ve set to be saved in the same name

I’m working on

I’ll be telling you about the token part later,

but for now, run the render

format is png

For other parts, you don’t have to see that much for now

in the Octane renderer, as you can see here

the various settings will be dealt with in the next class

and give you more detailed information

but for now, use the saved setting and render

how to do the rendering is, look at render here

If you press the render button in the middle, it starts its job

The specific render settings stuff

will be explained later

You can use tokens to render as the file name

You can use your own spline shapes or colors

and try on as many works as you can, and go into coloso site

There is an event ongoing right now

Hashtag coloso Woosung Kang

Upload it on Instagram

I am going to pick at most 3 people and give out coupons

I hope a lot of you participate in this event

This lecture took almost 1 hour

talking about the basic figure menu, basic spline function, and Subdivision

and Symmetry function, modeling using the spline and pen tool

and how to arrange the space using the spline

we’ve learned bunch of basic stuff today

If you couldn’t understand anything from this class today

, you should try doing it again

If you feel vulnerable when it comes to rendering,

I will be giving you lectures in class 5 to 7 on the Octane classes

so you can learn them from there

I will see you in the next class

Thank you
