Animation advanced Lighting application using Light examples
In this lecture, Hypergraph, Hierarchy
will be covered
Also, we will see what primitive shape
exist of polygons
and also learn about Combine, Separate,
and Smooth which are polygon's main commands
Maya's Hierarchy
I opened a new scene
Go to Windows - General Editors and look
Hypergraph: Hierarchy, click on this
Then the Hypergraph: Hierarchy window will pop up like this
Maya is basically a Hierarchy structure
You can group objects or
create a hierarchy
Let me give you a brief explanation and move on
I created a sphere
And Cube then Cylinder, Cone
I created four of them like this and I will upload them one by one next to each other
Press W to use the Move key
Sphere Then Cube, Cylinder, Cone
So, 4 of them were created like this
In the Hierarchy window, press F as well
Select a specific object and press F to make it full frame
Press A to get the whole thing
So, I'm going to create a Hierarchy structure
There is a Sphere Place the Sphere at the top
Let's make another object dependent on this one
I select Cone
Go to the desired location with the middle mouse button
Go under the polygon Sphere
Click with the middle mouse button
If you press and hold without releasing, you will see a + button
In this state, I'll go under the Sphere and drop it
Then, a hierarchy was created under the Sphere like this
So what happens then?
When you select Sphere, Cone is also selected
The reason for this is that the Cone is underneath the Sphere
That's because it's dependent
So when you move the Sphere, the Cone moves with it
This time, the polygon Cube
Likewise, let's put it back into Sphere again
When selecting, click with the left mouse button
Go all the way with the middle mouse button
Let's put it in sphere like this
Then, if you select Sphere, everything will be selected like this
This time I also select Cylinder
Do not release the middle mouse button
Let me go ahead and drop it on the Sphere What do you think?
If you select Sphere, everything else will be selected
And you can select them individually
Cone is also possible like this
This is basically the Hierarchy structure
So if you select the Sphere and Rotate it,
The rest all follow suit
Ctrl + Z will undo
Because this is a Hierarchy structure
In Maya
Because the Hierarchy structure is used a lot
If you know these basic things, it will be quite helpful
It will make it easier and more convenient to understand Maya
So again the Cylinder
Let's try to subordinate it to the Cube
Then select the Cylinder and use the middle mouse button
If you go to the Cube and drop it like this
Now the Cylinder is subordinated to the Cube
So if you select Cube, it becomes dependent on the bottom
The most important one here is Sphere
And if you look at your keyboard, there are arrow keys
If you press up like this, it goes to the top
Select pCube and there are up and down keys on the keyboard
Press the up arrow to go to the top
It's simple
I explained the Hierarchy structure
And in your Hierarchy window
If you want to disable these, select them one by one
I selected pCone
If you pull it out with the middle mouse button, it will come out one by one like this
If you select it and drag it out with the middle mouse button, it will come out like this
This time, I will briefly explain Snap
Open a new scene in Maya
Snap is located under the main menu
Here, this is the snap icon
There's a grid, there's a curve, there's a point, there's a shortcut
Keyboard X, C, V
X is the grid and C is the curve or edge
V is vertex snap
Let me give you a simple example
Undo and delete it
Let me create a Cube
I pressed F to make the window full frame
In this state, I will try to grow the Cube
Let's create one more Cube
Then there will be a Cube inside
Press F5 to turn on the grid
Wireframe is toggled
If you look at this state,
Let's click on the grid icon once
Shortcut - Icon - Click
Then I have this object
If you look here, this is Pivot, Manipulate Pivot
Let me move this Move Pivot What do you think?
This is called a grid, the gray lines
If you move along this grid like this,
It moves like a magnet on the grid
This is grid snap
And then turn it off again
The icon shape also changes from circle to square
This time I pressed the curve snap
This is the same for Edge too
So this is the icon you use when snapping to a curve or edge
So if you move it like this, you can see
I can't express it exactly right now
I'll try this with a shortcut key
Turn it off and the shape changes
In the current selected state
Since the shortcut key is C, how about pressing C?
Likewise, it is activated
Press C and move to the desired location with the middle mouse button
Let's try a snap effect here
Do not release the middle mouse button
Click and move
How about this? It moves like this
Let's try this here too this time
Click the middle mouse button and move it
Then, it snaps like this here
Let's try attaching it to this side this time, like this
I keep holding down C on my keyboard
Where you want to snap
You can position it freely and easily
Pressing 4 turns off shading
Let's try it on the other side Press C and do this on this side
Pressing 5 will switch back to shading mode
When you work like this
When you make something, using Snap
You can position it exactly as you want
It will be convenient to work with
Then at the end
The shortcut key is V
This time, I'll try pressing the shortcut key V
Then what do you think? Press V
You can see this getting activated
It also changes into a circle here
This time, press V and see
For polygons, vertices are
The point where these edges meet is called a vertex
This is the edge and this is the face
Let's press V and attach a vertex like this
So you can snap to the vertices however you want
And let's talk briefly about polygons
I think I need to explain a little bit, so I'll explain
I will provide further explanation later
First, let's delete this Cube
I have a polygon Cube right now
You can stick this on this side
Basically, I think it would be easier from the side
If it's a C snap, it will stick to this edge
But if you press it like this without limiting the axis,
It's a bit crooked like this
So let's put a limit on the axis
How does it move after doing that? It will only move along this line
Then, if you press C, it will move like this
If you fit it here, it will come down exactly like this
So, using Snap
It's really convenient for modeling
So I want you guys to know a little bit about this
I hope you all can test it out for yourself right now
I open a new scene
This time, let's choose Sphere and increase the scale
While I was just working on this
Selected the face and selected the edge
Then I selected the vertex and showed you things like this
If you look closely here,
If you look under the Maya main menu, there are three icons
Sometimes errors occur
Rather than an error, it just doesn't come out exactly right sometimes
So the first one is Hierarchy mode
Next is object mode, then component mode
So sometimes when you need to edit an object
and when editing doesn't work, check if it's pressed here
If you want to keep doing it in object mode
but you keep seeing vertices or edges being selected,
You need to make sure the center object mode is clicked
And strangely, if you only chose one, and multiple ones get selected
check if Hierarchy mode is pressed
So the Hierarchy, object, and component editing modes
You need to check if it is set correctly
So I'll explain it briefly and show you
This is also the same as the Hierarchy window
Let's try to subordinate Cylinder1 to Sphere
Then, in Hierarchy, Cylinder goes under Sphere
Select the cylinder and with the middle mouse button
I'll drag it and drop it on top
Then what? It changed to plus
If you click, it goes down
So what if you choose Sphere?
Since Cylinder is a sub-concept, they are all selected together
But what about now?
Suddenly, the object is not being selected, but the edge is being selected
Sometimes this becomes a problem and students ask a lot of questions
In that case, check if the mode we have chosen now is
component mode or object mode
or Hierarchy mode
So please stop saying it's weird
Go up there and click once
Then this is object mode and this is hierarchy mode
So, if you check this,
What state am I in now that the work is starting?
It is easy to check and prevent errors
This time in edit mode
Let me briefly explain Selection
Polygons in Maya basically have
vertices, edges, and faces
How to select this easily
There is a shortcut key, let's take a look
If you look now, it's component mode
I selected one face
And I selected one edge
Then you can select each vertex individually
But to make your work easier,
You may want to select quickly
In that case, I will tell you the shortcut key
Hold down Shift and don't release it
If you look next to the keyboard, you will see between the question mark and M
This shortcut key will appear on your keyboard
Try pressing this and see what happens
It expands like this, it grows and it shrinks
You can make your selection quickly
So if you right-click, it expands like this
If you press the left button, it will zoom out like this
Likewise, select the edge
Likewise, if you right-click like this, it will expand
If you press the left button, it will zoom out like this
Likewise, select the vertices and hold down Shift
If you press the right bracket button, it will zoom in like this
If you press the left button, it will zoom out like this
If you know this, you can work easily and conveniently
I opened a new window in the workspace and created a New Scene
And I'm going to make a Cube
So let's scale it up
If you look at it, I said that there is something called an axis in the object
So green is the Y-axis, blue is the Z-axis, and then red is the X-axis
But you can change this axis
Of course you can change the axis
When you want to change the axis,
You can change it like this by pressing the Insert key
And there's a shortcut key to do it faster, D
Same thing happens if you press D
So in my case, I press D to change and then release it
Then it will be restored to its original state
No need to do things twice
Press the Insert key and then
I have to do it again and again and it's the same thing
The Insert key and the D key have the same function
So I press D and snap to V
Let's move the axis this way
Press V snap and click with the middle mouse button
And when I let go of my hand, the axis moved like this
Then its axis is now fixed here
If the axis changes like this, you can change the Rotate axis
Since the axis is based on this side, it will rotate around here
Then you might be wondering if there was a way to
restore the axis to its original state
If you go to the Channel Box here and put in 0,
The axis doesn't move
Because the axis itself is based here
I just moved the axis
So, we can restore it to its original state
It's a bit ambiguous to say it's a method
You can send it to the most central part of this object
But because I didn't deform
the polygon Cube object
You will be able to move around the axis
So there is a command
If you go to the main menu, you will see Modify
If you go all the way down, you'll see something called Center Pivot
This is also possible, and for those who use the marking menu
Press the space bar and hold down the middle mouse button
Then there is the Center Pivot at 11 o'clock
Center Pivot with the middle mouse button
Keep going without lifting and then press the middle mouse button
How about clicking like this?
The axis has shifted to this side again
Pressing the Move key also does the same thing
So we learned about moving the axis briefly
And you guys, if I move to the side
How about Channel Box? You can see the coordinates changing
If you do the Rotate button, you can see that the Rotate value also changes
If the scale changes, the scale value also changes
It comes out like this
There may be times when you want to change this axis to zero
Translate value 0, Rotate value 0
If you want to keep the scale as 1:1, then
There is a way to do this by baking it
It's called Freeze If you just freeze it,
This numeric value changes to 0
So let's press Freeze Transformations in Modify
Then what? It will change
So now here it becomes the standard
This guy is now at zero point
So, you have to be careful when making decisions when working
What shapes and objects I create and
If you want to initialize it when you're done, then
Just click Freeze Transformations in Modify
Likewise, in the case of Maya,
Because it provides history options
The things I've worked on are stacked into a history
So if you go to Channel Box and look
If you look at INPUTS under the Shape node,
Here is the command I just ran
So, as this history stack builds up,
The data can become heavy and slow down your computer
Because errors may occur
If you do not want to make any more changes or alterations,
It would be a good idea to clear the history
So how do you clear history?
If you go to Edit, you will see Delete by Type - History
So the shortcut key is Alt + Shift + D, and if you click on this,
If you look near the INPUTS node under the Channel Box,
As soon as you press that, the history node
You can see it clearing
Then you can see that it cleared away cleanly
So, to keep it simple here
I explained about axis movement
Polygons in Maya
We will open a new scene
Since this lecture is mainly focused on polygons,
for how to create a polygon
and where the polygon is located
Let's take a quick look at the menu
If you guys go to the main menu,
Modeling must be selected
If you go to Create, you will see
I'll just take the tab off
If you go and look
I said I could take it off
Below are NURBS Primitives
Then there are Polygon Primitives
If you do this, it will fall off
Then Sphere, Cube, Cylinder
Torus, Plane, and Disc are there
Let's try creating them one by one
The sphere looks like this
Then Cube
I'll toggle the wireframe for easier viewing
These are the presets provided by Maya
In my case, the one I use the most is
Sphere, Cube, Cylinder and then Cone
I think it's about this much, I don't really use the rest
Basically, it looks like this
It would be nice if you guys had a grid
but sometimes I don't want to see the grid
Then, if you look under the submenu above,
There is a grid icon, if you click on it the grid disappears
If you want to see it again, click on the grid
These are Polygon Primitives
Reopen the window and turn the grid back on
If you go and create them one by one
It will take time to work and may be a bit inconvenient
So, using the Shelf window,
There is a way to simply register and use it, but
In my case, I hold down the shortcut key Shift on my keyboard
When you right click the mouse
Basically the same menu appears
So a Cube is created and then a Cylinder
You can go there yourself and create them one by one, but
It's more convenient to create it this way
I think you guys will find this method more convenient
Shift + Right Click
Because you can use more options equally quickly
The shortcut key is Shift + right click
A window like this will appear
And then go to where you want and choose
When you release the right mouse button, this is what happens:
I briefly explained the history options earlier
So I select this and when I'm done with the work
Let me erase the history once
Go to Delete option and select Delete by Type - History
If you look below, you can see Delete All by Type
If you select Delete All by Type
Because everything inside the scene will be deleted
If possible, please be careful
If you only want to clear the history of the selected object,
Delete by Type - Select History
The shortcut key is Alt + Shift + D
So if you click on history
There is a history in INPUTS under the Channel Box
You can see it being deleted right away
It gets deleted right away, so if you compare it
This one has history and this one has been deleted
The data values ​​have become lighter
Should I delete this too?
Let's try using the shortcut key
What was the shortcut? It was Alt + Shift + D
Then you can see it disappearing as soon as you press it
If you undo it, it will appear again
So I just checked the input node and let's move on
And likewise, to review
I said there was an Attribute window
In the case of Maya, for very similar options
There are repetitive commands that show different ways:
In the case of Channel Box
You can think of it as a brief overview
If I want more detail
If you want to check every detail
I said there was an Attribute window, literally an attribute window
So, pressing Ctrl + A is the shortcut key
All the properties about this are listed here
So first, when you press pCone,
It's the same as its Transform value
And if you go to the second, polyCone
These details that we saw here
is the same
If you move the slide bar left and right
It can be adjusted in this way as well
So if you press Ctrl + A, a detailed options window will appear
The attribute window will pop up Ctrl + A
In my case, let me give you a tip
Instead moving the slider directly
If you move here, you can see detailed movements
are a bit impossible and difficult
In my case, while holding down the Ctrl key
If you move the mouse after clicking the left button
Because it moves subtly
You can work more conveniently
And here's one more tip:
If you look here, there are three icons
At the end, if you have time, click on the icon
There are some options that will change the values ​​depending on the option
And there are three mouse buttons
So on the left and right buttons
The left button moves a bit more subtly
The right button is faster
It's different from the middle button
If you hold down Ctrl and move the left button, it is in decimal unit
Hold down Ctrl and right-click the mouse
It moves in integer units like this, so there is a difference
The middle button is the median value
So when you want to move in detail
In my case, I hold down Ctrl and use the left mouse button, LMB
You can do it in detail by holding down the Left button and moving it like this
In my case, I find this much more convenient, so I use it this way
And the rest are options related to shading
And let me tell you one more thing
If you look at your keyboard, there are arrow keys
There's Up, Down, Left, Right
There are four arrows on your keyboard
In my case, I hold down Alt and move left and right
It can be finely adjusted
This is because it moves in pixels on the monitor
If your monitor is 4K, you can move more finely
It's FHD so it'll move faster
I'm just letting you know for your reference
Open a new window
About the most used polygon commands
I will briefly go over only the essential parts
First, if you look at Mesh, there is an option called Booleans
I will explain this later
Let me explain Combine first
I created a Sphere
Polygon Sphere, then Polygon Cube
I created these two
Let's toggle the wireframe
If you look in front of you
If you look at the submenu in the view panel, there are icons
If you look, this icon is a wireframe toggle button
In my case, I'm just pressing Alt + 5 and doing it now
To confirm
I toggled the wireframe on purpose
If you look at Mesh, there is a menu called Combine
What is this menu called Combine?
If you look at it, each object is recognized individually
If you look at the Outliner, you can see that it is recognized as two objects
But there are times when you might want to combine these into one
There is such a menu
So you can choose two, maybe three
This way, as much as you want
If you want to recognize this as one object, then
There is a menu that combines them into one, that is Combine
So what happens if I press Combine?
In this way, it becomes a single object
But, because the history remains
If you select one by one, it moves one by one
So what do you do when these guys are done with their work?
I said you should delete the history
What was the shortcut? Alt + Shift + D
I'll go and delete it myself
So what now? Because the history has been deleted
These guys have now become one object
So if you check the object now in the Outliner,
There are three things visible
Actually there are two objects
This is a command called Combine
This time I made them into one object
You can detach it, of course, but you can also undo it
If you had several tasks like this
It'll take a long time to undo that
So in that case,
You can separate them
There is an option called Separate
Let's run Separate once Click
Then what? It was split into two objects
And what do I always say you do when you're done with your work?
I said you should delete the history
Because the history remains
So if you think you have no more use for history,
Clearing the history stack is always the order of operations
So Edit - Delete by Type - History
This would be faster if you used shortcuts
Likewise, the axis is here
If I didn't intend it
There is no need to put the axis here
So there was a command to change the axis around
Remember what it is?
Center Pivot The axis comes back here
Select this one too and Modify - Center Pivot
How about now?
The data was neatly completed as a single object
Let's try combining these three again
Then, when you combine them, you get one object like this
If you don't want me to use your history anymore,
Pressing Alt + Shift + D will clear your history
So far, we have looked at Combine and Separate
This time, let's take a look at Smooth
I opened a new window and created a polygon Cube
I scaled it up a bit and pressed F to make it full frame, then Alt + 5
What is the menu called Smooth?
It literally makes it smooth
If you look here, there is a menu called Smooth Click on it
How is it? It's smooth now
And the Divisions number next to it is currently 1, shall we increase it?
You can adjust the numbers like 2, 3, etc.
And I gave 1
The shape comes out a bit strangely soft
This is a function on the display
There are 1, 2, 3 on your keyboard These are the functions
5 - 1 is correct
So go to Channel Box
The history is remaining in the input node
Divisions values, with the middle mouse button
Even if you move left and right, the command works like this
It comes out smoothly
This is the menu called History
This is 0, 1, 2, 3, 4, 5, it works smoothly
I go up to 4 and it doesn't work anymore
If I want to give more, one more time
If I re-run Smooth the numbers go up again
If you give too much, your computer might crash
You will need to adjust it while looking at the data appropriately
And this was the option called Smooth
This time we covered many menus and options
It's hard to understand exactly after seeing it just once
If you guys keep repeating this two or three times,
I really want you to make it yours
Let's summarize what we learned in this lecture
We briefly looked into Hierarchy structure
And we also learned about the primitive shape of polygon
Finally, we covered polygon commands
Combine, Separate, and Smooth
I hope you watch this again
Maya's Hierarchy
Hierarchy A structured array of nodes or objects
Select Windows - General Editors - Hypergraph: Hierarchy
Select one polygon and hold down the middle mouse button at the bottom of another polygon
A + button appears next to the cursor
You can move a polygon and make it a child of another polygon
You can separate them by clicking on the dependent polygon and then middle-clicking on an empty space
Maya Polygon Creating Polygons
Create - Polygon Primitives - Clicking on the top will create a list of Polygon Primitives
Create polygon primitives from the marking menu by Shift + right-clicking the mouse
Check polygon information
Channel Box: Shows brief information about the selected object
Attribute Editor: Lists the properties of the selected object in more detail
Modify polygon
Combine: A function that turns selected objects into one object
Separate: A function that divides a polygonal mass into separate units as a single object
Smooth: A function that makes the shape of an object smooth by increasing the surface area
