Realistic Basics Understanding Blender Tools and Functions
Hello, I am Hwang Seong-min, and I will be giving a lecture on 3D Blender
There are various 3D production tools
for creating realistic content
Among them, 3D Blender is a 3D production tool that is widely used
because it is free software
and has an active community,
so you can easily find various tutorials and materials
When you first encounter any 3D production tool
it is bound to seem unfamiliar and difficult
I hope this lecture will allow you
to think of 3D Blender
as a familiar and easy tool
This is the first lecture on 3D Blender
We will learn how to install a 3D Blender
and the functions of each area
Finally, we will learn about
the basic functions
used for modeling using a 3D Blender
I will proceed with the lecture slowly from the beginning
so it would be good if you watch the lecture and follow along slowly
Understanding How to Install 3D Blender
Let's first learn how to install Blender
You can search for Blender
in English or Korean in the Google search bar
and find the Blender homepage
If you have trouble finding the Blender homepage
access it at www.blender.org
When you access the Blender homepage
click the Download menu on the Blender download site
Click the Download Blender button
to download the installation file
that matches your operating system
Suppose you need a different file for a different operating system
In that case, you can click the macOS, Linux, and other versions button below
to download the Blender installation file
for your desired operating system
If you want to download a version of Blender
that is not the latest
click the Looking for previous versions
menu below
and click the Download Any Blender button
once more to select
and download the version that matches
your desired operating system
You can check that the installation file has been downloaded
to the specified path
If you have trouble finding the installation file
it is downloaded in
the download folder by default
so you can find it through the download folder
Double-click the installation file
to proceed with the installation
Suppose you want to install
in a different format than the installer
In that case, you can go back to the Blender download homepage
and click the macOS, Linux, and other versions button
to download an installation file in a format
other than the installer
Once the installation is complete
you can see the Blender executable file on the desktop
and run Blender immediately by double-clicking it
This pop-up window is called Splash Screen
and contains a simple menu
that can be used when running Blender
There is a menu to create a new Blender file that fits the task,
select it, and load a Blender file
There is a menu to load a Blender file you recently worked on
It would be good to get used to it
because you can quickly create or load a Blender file
using the Splash Screen window
If you have nothing to do with Splash Screen
you can close the Splash Screen window by pressing the Esc button
or pressing the blank screen
Let's first learn about the menu window
at Blender's top
When you click the Blender icon,
Splash Screen, About Blender
and Install Application Template
you can see three menus
The Splash Screen menu is
a menu that allows you to re-open the Splash Screen window
The About Blender menu
is a menu that allows you to open an information window
about the Blender you are currently using
In this information window, you can check various information
such as the current Blender version,
Blender compiled date, etc.
The Install Application Template menu
allows you to install a new template in Blender
Using this menu
you can change Blender to suit your needs
by using the scripts you want
Let's take a look at the File menu
The File menu contains menus
that allow you to manage files
The New menu creates a new scene
the Open menu loads a saved Blender file
and the Open Recent menu checks or loads
the most recently opened Blender file from the list
The Revert menu is a way
to open the current scene as the most recently saved version
and Recover is a menu to load the file saved
just before Blender was shut down
The Save menu saves the current Blender scene
and Save Incremental is a method to save with a different name
by directly linking the file name number
instead of saving to the existing saved file
Save As is a menu to save by specifying the file name and save location
and Save Copy is a menu to save a copy of the current file
Link is to connect an external Blender file
Append is to add external Blender file data
to the current file
Data Previews is a tool for previewing data blocks
Import is a menu required when loading a file created in another program
Export is to export it to be used in another program
and Export All Collections
is to export all of the collections
External Data is a menu required
when saving external data such as texture images
and other resources inside the Blender file
or as a separate file
Clean Up is a menu required when deleting unused data
Default is a menu used when creating a new Blender scene
or managing files
that set the initial screen
Finally, the Quit menu is used to exit Blender
and if you exit using this menu
it will be saved as a file called quit.blend in the temporary path
The most frequently used menus in the File menu
are the New, Open, and
Open Recent menus
and the Save and Save As menus needed for saving
are used the most
I recommend you study the rest more
and use them whenever necessary
Let's learn about the Status Bar
The Status Bar is at the bottom of the Blender window
and displays information such as keyboard shortcuts and messages
The left side of the Status Bar displays the mouse button shortcuts
and the keymap of the active tool
You can use the displayed information
to quickly identify and use the shortcuts
you need while working
If you press the Move, Rotate, and Scale shortcuts
you can see the shortcuts you can use
at the bottom left
If you change to Edit mode and activate the Bevel function
you can see that other shortcuts appear
This way, you can see which shortcuts are included
and can be used
when using various tools
You can check the status messages in the center of the Status Bar
This is where you can check information
about the current task in progress
The progress of the currently running task
such as rendering or baking
is displayed,
and you can also click the X icon to stop the task
It also displays information after saving the file
The status bar's right side displays data
about the active Blender scene
The name of the active scene, object names
information about the current scene for the mode
number of selected objects and total objects
current frame number and total frame number,
and the played time
information about Blender RAM consumption
information about extension updates
Blender version
You can see a lot of information
You can change the information displayed here
by enabling or disabling it in
the Status Bar in Edit -
Preferences - Interface
Let's learn about the Edit menu
The Edit menu is one of the menus that is frequently used during work
There are many menus
but let's look at a few of the most frequently used menus
First, the Undo menu in Edit is a function that allows you
to undo mistakes or unwanted actions
during work
As you can see in the current screen
if you want to move a cube and cancel the movement
you can undo it by pressing Edit - Undo
or you can undo it by pressing the shortcut key Ctrl + Z
Since the Undo function is used frequently
I recommend that you memorize and use
the shortcut key Ctrl + Z rather than using the Edit menu
Next is the Redo function
The Redo function is used to use the Undo function
and restore it
This is often used to go back
when you accidentally pressed Undo
or pressed it multiple times via a shortcut
Undo History is a good function when you return often
because you didn't do what you wanted to do during work
It is a good function to use
when you have a lot of work to do and need to press Ctrl + Z
and Undo a lot or when you want to
quickly go back to a previous work
Next is the Repeat Last function
This function repeats
the last work you did
If you copy the cube like the current screen
and press the Repeat Last function
you can see that it is copied once more
The shortcut key for the Repeat Last function is Shift + R
so it is a frequently used function
I recommend that you memorize it and use it
Next is the Rename Active Item function
This function changes the name
of the currently activated object
by pressing it
When we build an environment using many objects
some parts are confusing about
how each object is used
so we recommend that you change the name
when checking the list in the outliner and proceeding with the work
Let's take a look at the remaining Top Bar menus
The Render menu contains
menus for rendering
Next is the Window menu
which can change the settings for the window
you are currently working on
or change it to a different workspace
Next is the Help menu
The Help menu is a menu window where you can find
and check information you want to know about
such as the Manual, Release Notes
and Tutorial
Next, let's take a quick look
at the workspace
It is a predefined menu that allows you
to change the workspace depending on the task
It can be used for specific tasks
such as modeling, animation, or scripting
Using the shortcut keys Ctrl + Page Up/Page Down
you can change the mode
When you first run Blender
the workspace you see is the layout
In the layout workspace, you can see the 3D viewport at the top left,
he outliner at the top right, the properties at the bottom right
and the timeline at the bottom left
Also, by clicking the Add+ button
you can also create a new workspace
The Modeling Workspace allows you
to focus more on modeling work,
and the Sculpting Workspace allows you to sculpt meshes
The UV Editing Workspace allows you to do texture mapping
and the Texture Paint Workspace
allows you to paint textures in the 3D viewport
The Shading Workspace allows you to specify materials
and the Animation Workspace
allows you to focus more on animation work
The Rendering Workspace
allows you to work while checking the rendering results
and the Compositing Workspace allows you to perform
further post-processing, such as rendering
The Geometry Node is a workspace
where you can use nodes to model
and the Scripting Workspace is a workspace that you can use
when writing Python scripts
Next, I will explain the Header
A menu in the Header allows you to change
the viewport you are currently viewing
You can change to the desired viewport
to work smoothly in the desired viewport
Next is the Object mode to Edit mode
This function allows you to change from Edit mode to Object
If you change the Edit mode
instead of working on objects
you can work on vertices, edges, and faces
Next is the View function
The View function allows you to hide or show menus
such as the toolbar and sidebar
The Select function is a selection function
It contains functions to select everything, none
or invert the selection
Next is Add
Add contains functions
for creating new objects
such as Mesh, Curve, and Surface
The Object function contains various object-related functions
such as Transform, Set Origin, and Mirror
We will use the Apply and Join functions
in the modeling class
Next is the Transform Orientation feature
The Transform Orientation feature
allows you to determine the direction of the object's gizmo
Changing the direction of the object gizmo
makes it easier to work on the transformation in the desired direction
Next is the Pivot Point feature
The Pivot Point feature
allows you to change the position of the object gizmo
Changing the position of the object gizmo
makes it easier to work on
the transformation centered on the desired point
Next is the Snap feature
which allows you to move like a magnet
to the cursor or selected point
Next is the Proportional Editing feature
which affects not only the selected part
but also the unselected parts
The farther away from the selected part, the less influence it has
This feature
can be useful for smoothly
changing a dense mesh
Next is the Selectability feature
The Selectability feature is a feature
used to view or hide desired objects by type
When working with multiple objects
you can view only the necessary objects
or hide only the unnecessary objects
Next is the Viewport Gizmo feature
The viewport gizmo feature
hides or shows the contents
displayed in the viewport
Next is the viewport overlay feature
The viewport overlay feature
is a feature that hides or shows the information displayed
in the viewport in the form of an overlay
Next is the feature that allows you to change the viewport
There are five types of viewports: X-Ray, Wire Frame, Solid
Material Preview, and Render
You can change the viewport to suit your work
and we are currently looking at the Solid viewport
To briefly explain the viewport
the X-Ray viewport
can be used to make the scene transparentThe Wire Frame viewport
The Wire Frame viewport
can be used to work by showing only the edges of the object
The Solid viewport is a viewport that shows solid geometry
but utilizes simplified shading and lighting
without using shader nodes
The Material Preview viewport
is especially suitable for previewing materials and painting textures
You can test materials
by selecting various lighting conditions
The Render viewport lets you preview the final result
which includes the scene and lighting effects
It is a viewport that allows you to see
the rendered image as closely as possible
Next, I will briefly introduce and explain
the most frequently used functions in the toolbar
The toolbar has the Select, Cursor, Move, Rotate, Scale
Transform, Annotate, and Measure functions
The Select function has the Tweak, Box, Circle, and Lasso functions
and depending on the selection, the object is selected in a different form
The Tweak Select tool is a tool that selects one object
and moves it when you drag it
The Box Select tool creates a rectangle when you drag it
and when you release it, you can select all objects
that overlap or are completely within it
The Circle Select tool selects all objects
within a circle when you drag it
You can also change the circle's radius
in the settings in the Header
The Lasso Select tool can create a shape
whose shape is not fixed by dragging
and after releasing, it can select all items
within the Lasso Select tool
When selecting with the Box, Circle, and Lasso Select tools
objects within the area are selected
and objects outside the area are deselected
The cursor is a function that can change the position of the 3D cursor
Move can change the position of the object
Rotate can change the angle of the object
Scale can change the size of the object
The Transform function is a function that can transform
the Move, Rotate, and Scale functions at once
The Annotate feature can be used in many places
It can be used to add notes
to 3D objects or node settings
The Measure feature can measure distances
in the viewport
Let me explain the Outliner
The Outliner is a list that organizes
the data in the Blender file
the scene data, the video sequence data, or all the data stored in the Blender file
The objects you are currently viewing
are also listed here in the Outliner
Next, I will explain the Properties window
The Properties window displays
and edits a lot of data
You can also add functions to the object
you currently view on the screen
We will use the functions
in Properties when modeling
As you can see on the screen
you can add a function to make the edges smooth
or add and modify a material
There are more functions
than those used in the lecture
so I recommend that you study them one by one
and take the time to apply them
Understanding the Basic Functions of 3D Blender
Before the modeling in the second lecture
let's take some time to learn
the basic functions of Blender through practice
When you run Blender
you can see the first screen with the Splash Screen
Since we have nothingdon't else to do in the Splash Screen
we will close the Splash Screen pop-up window and proceed
To close the Splash Screen
press the shortcut key Esc
or close the blank screen by left-clicking it
You can check the camera, cube, and light
three objects in the 3D viewport
Let's delete the three objects of the camera, cube, and light
and create new objects
You can select the objects
by dragging the mouse using the Select tool
and delete them using the shortcut key X
or you can select the entire object by selecting the object
using the shortcut key A
and pressing the Delete shortcut key X to delete them
You can create an object
by selecting Add in the Header menu
or pressing the shortcut key
Shift + A
It is also a good idea to create other meshes besides cubes
and check what kind of meshes there are
Let's first check how to check the created cube
through the viewport and proceed
Let's try rotating the viewport
If you hold down the middle mouse button and move the mouse
the viewport will rotate according to the direction of the mouse
If you need to work on or see another side of the object
you can rotate the viewport by holding the middle mouse button
This time, let's move the viewport
If you hold down the Shift button and the middle mouse button
while moving the mouse
the viewport will not rotate but will move in a fixed state
You can use it to work on
other objects next to it
To zoom in and out of the viewport
you can turn the mouse wheel
If you have difficulty using the mouse wheel button
you can see the zoom in and out
by holding down the Ctrl and middle mouse buttons while moving
Using the keypad, you can look in the direction you want
Pressing 1 will change to the front view looking straight ahead
pressing 3 will change to the light view looking from the right
and pressing 7 will change to the top view looking from above
If you hold down Ctrl and press 1, 3, and 7
you can see the view in the opposite direction
of the previous direction
If you are using a keyboard without a keypad
you can change the settings to change the number of keys
at the top of the keyboard to act as a keypad
Check the Emulate NumPad option
in Edit - Preference - Input - Keyboard
After that, if you press 1, 3, and 7 in the viewport,
you can see that the view changes the same way
as pressing the numbers on the keypad
If you change the option like this,
it may be a little inconvenient when modeling later
This is because 1 to 3 are shortcuts to select
vertices, edges, and faces
I will tell you one more way to change the view
Again, go back to the option
in Edit - Preference - Input - Keyboard
close the options window, and then, in the viewport screen
hold down the keyboard tilde key on the viewport screen to the left
of the 1 shortcut key
A UI window like the one shown on the screen will appear
Place the mouse over the menu you want
and release the tilde key, then you can see that the screen changes
There are several ways to change the view,
so you can work using the desired method
This time, let's practice moving
rotating, and resizing objects, not the viewport
First, let's delete the previously created objects
by selecting all objects with the shortcut key A
and the shortcut key X for Delete
Then, let's create a cube object
with the shortcut key Shift + A for Add
Let's practice the Move function on the toolbar first
If you click on the cube and then select the Move function
you can see the gizmo for the Move tool
The green arrow can move along the Y axis in the Blender viewport
the red arrow along the X axis
and the blue arrow along the Z axis
The red square icon moves along the Y axis and Z axis, excluding the X axis
the green square icon moves along the X axis and Z axis, excluding the Y axis
and the blue square icon moves along the X axis and Y axis, excluding the Z axis
Let's show you how moving feels
by rotating the view once more
If you click on the cube and press the shortcut key G
you can use the same Move function
However, unlike when you click on the function on the toolbar
no arrows appear
and you can see that the cube moves
in the direction the mouse moves
In this state, using shortcut keys
if you want to move to the desired axis
just press the key for the desired axis
If you want to move to the X-axis, shortcut key X
if you want to move to the Y-axis, shortcut key Y
and if you want to move to the Z-axis, shortcut key Z
If you want to move the Move tool more precisely
hold down the Shift key while moving
Next, if you want to move 1m at a time
hold down Ctrl while moving
and it will move 1m at a time based on the initially moved location
This time, let's practice the Rotate function
The basic part is similar to the Move tool,
so you can use it similarly
Select the cube and select the Rotate function from the toolbar
You can see that a different gizmo has been created
compared to when you select the Move function
The white circle is the gizmo that rotates based on the view
Red rotates based on the X-axis
green rotates based on the Y-axis
and blue rotates based on the Z-axis
The Rotate shortcut key is R
You can use the X, Y, Z
Shift, and Ctrl buttons like the Move function
Next, let's select the Scale function
while holding down the cube
The Scale function has a gizmo shape similar to the Move function
The basic function works similarly to the Move and Rotate functions
You can adjust the size in the desired axis direction
by pressing the arrow and square gizmos
The Scale shortcut key is S
The X, Y, Z, Shift, and Ctrl buttons
can also be used like other functions
If you look at the Header
you can see that it says Object Mode
In Object Mode, you can modify objects in units of objects
If you press the object mode to change to Edit mode
ou will change to a mode
where you can edit objects
in units of vertices, lines, and faces
If you press the desired object
and then the Edit mode shortcut key Tab
you will change from object mode to Edit mode
Pressing the shortcut key Tab once more
will change from Edit to Object mode
Let's change to Edit mode and edit the cube
By selecting Vertex Select mode, Edge Select mode
and Face Select mode,
you can change the mode to select points, lines,
and faces separately
To select additional vertices
from the selected vertices
hold down the shortcut key Shift and click
To deselect the selected vertices
hold down Shift
and click the selected vertices once more
You can use it similarly for object mode
or other edges and faces
Select the cube's vertices
and use the Move, Rotate, and Scale functions
The Vertex Select mode is shortcut key 1
If you want to select one vertex,
you can see that the Move function works well
but the Rotate and Scale functions do not work
This is because even if one vertex
changes its Rotate and Scale values
the entire object does not change
Let's select two vertices
and use the Rotate and Scale functions
After selecting two vertices
you can see that they work well
This time, let's change the edge by selecting the Edge Select mode in the Header
or pressing the shortcut key 2 to change the mode
so that you can select the edge
I recommend you freely utilize the functions you have learned
and try transforming them
Similarly, let's select the Face Select mode in the Header
or press the shortcut key 3 to change the mode
so that you can select the face
I recommend you freely utilize the functions you have learned
and try transforming them
Next, I will introduce functions that can be used in Edit mode
Extrude, Insert Face, Bevel, and Loop Cut
I'll introduce those four functions
When you change to Edit mode
you can see what functions are added
to the object mode in the toolbar
The Extrude function is a function that adds
the selected face in the desired direction
You can also use the Extrude function with the shortcut key 1
As you can see now
you can add the selected face in the desired direction
After completing the modification
you can press the Adjust Last Operation shortcut key F9
to further supplement the modifications
The Insert Face function adds
a face inside the selected face
The shortcut key is I
As you can see, you can add
a face to the selected face to the desired depth
After completing the modification
you can press the Adjust Last Operation shortcut key F9
to supplement the modification further
The Bevel function is a function that adds an edge to the selected corner
to create a gentle corner
The shortcut key is Ctrl + B
As you can see, you can split the selected corner
to create a gentle corner
After completing the modification
you can press the Adjust Last Operation shortcut key F9
o supplement the modification further
The Loop Cut function is a function that cuts the face at the desired location
and adds an edge
The shortcut key is Ctrl + R
As you can see, you can cut the desired face
and add an edge
You can also modify the object's shape into a different shape
by adding an edge and moving it
You can use Loop Cut to move the edge to the desired location
and modify the vertex and edge
to create a different object type
Therefore, if you use it well
it is a function that can create an object in the shape you want
I recommend you learn how to modify objects
in various ways by adding Loop Cut
After completing the modification
you can press the Adjust Last Operation shortcut key F9
to supplement the modifications more
Next, let's learn about
the Bevel function in the Modifier
Select the cube and select Modifiers – Generate
and Bevel
When Bevel is applied, you can see that
the cube's corners become smoother
Looking at the Properties window on the right
you can see the Amount and Segment option
Adjusting the Amount value
will adjust the width of the soft corners
Adjusting the Segment value
will adjust the intensity of the soft corners
We will model a rounded and smooth shape overall
by giving the Bevel value in the Modifier during modeling time
There are various functions in the Modifier other than the Bevel
that we have just introduced
So I recommend you apply them to the objects individually
and take some time to learn about them
Lastly, we will learn about the Shade Smooth function
Shad Smooth function
keeps the outline of the object the same
However, it changes the way the shading
is calculated across the entire surface
making it look like a smooth surface
We will apply the Bevel and Shade Smooth functions
to make the object a little rounder
This time, we learned about
the basic functions of 3D Blender
As I mentioned, it will naturally feel difficult because it is your first time
Still, if you master the basic functions well
you can improve your skills as much as you practice
so please understand the basic functions and move on
Then, we will finish by summarizing what we learned this time
