Animation Basic Basic Rendering
Hello
This is Park Junyoung, in charge of the basic 3D animation lecture
Until now, we have learned how to move characters
and create animation
Today, I will teach ways to make the characters look flawless
which are called lighting and rendering
First, the default plugins of maya
Using scanline renderer
We will set simple lighting
and check on the results
Then, utilizing arnold renderer
we apply a more luxurious lighting and shadow
to see the difference
Instead of lengthy explanations
following the examples step by step
will be much more fun and easier to understand
Now, shall we execute maya?
Three-point lighting and Arnold renderer
This time, we will start lighting
Bear ani work which set the animation
in the previous lecture
We will try to set lighting
First, the menu set
should be modified to Rendering
And if you look above
The slate icon which shows up when filming movies
there is a cogwheel drawn on it
If you click on it
A window called Render Settings will pop up
As a default, maya 2010
I don't remember what number it starts from
but it will be set to arnold renderer
First, set it as maya software
We call this maya scan line
We are not going to print a rendering image right now
but it would be nice to set it as a default lighting
And, don't touch on the other settings
Move over to Maya Software
Production quality
Just click on this
Maya provides multiple renderers that are
capable of rendering
There are three default maya renderers
Maya software, maya hardware 2.0 isn't actually
used very often
But maya software is
a very basic maya renderer
So at first, we use it to explain
Next, I will set it to arnold renderer
First, in this condition
Click on Create, Lights, Spot light
You can see that a small light has been generated over here
It is a cone shaped light
In order for this cone to point at our bear
Take it out
For the pointers of the cone to point at the bear
Take it out and let's move it around
And press number 7
Then following the direction of the cone
you can see that a light is shining
You can adjust the cone to make it bigger
And this part of the cone is very narrow
So the amount of light that is equal to this area will point at the bear
This area seems too narrow
Then if you press Ctrl+A
A setting called Attribute Editor pops up
Now this is Attribute Editor
You can see the traits of this lighting
So if you move over to SpotLightShape over here
Intensity, which is the light intensity
Color which stands for the light color
If you come down to the bottom
There is something called a Cone Angle
Now, in this way
If the Cone Angle becomes wider
The area that receives the spot light will be wider as well
You can see it this way
The joints over here
Stick out from the modeling
how the lighting is set cannot be seen clearly
If you look at the bar over here
There is something called X-Ray joints
I will click on it to make sure the skeleton cannot be seen
First, there is one lighting
We can consider this as the key lighting
and I will copy one more of this lighting
Copy it, and from the further back side
I will shine the light on it
Like so
Move over a little bit
First, adjust the intensity down to 0.5
Like this way
We call this Rim light
Then go over to Create and Lights
Take out one Ambient
You can think of Ambient Light as the overall natural light
If it gets too bright
It seems a little foggy
Then you can adjust the colors a little bit
Lastly
This is called Fill light
Key light
It is called key light
If the key light shines
it will be seen where the shadow is made
The spot where you can see the shadow
It can't be too dark
So it plays the role of brightening it
So the original key light
and the fill light
This is the rim light
This rim light shines the outer edge of the back
the dark side of the outer edge
It lights up this part
Whether rim light is there or not
can affect the quality quite a lot
Like so, we call these three
the 'three-point lighting'
These are the three default sets that are used often
And this Ambient
Whether this place and scene is
during day time or night time
This light plays the role of determining it
If it is done without the Ambient
It seems like the night time
Even though the fill light is shed on
It is quite different from setting the light up during day time
and filming after setting up the light at night
What sets the difference is
the role of Ambient
In this condition, if you look at the key light
You can make it pop up by pressing on Ctrl+A
Attribute Editor
Turn on Use Depth Map Shadow over here
It is usually turned off
And set the Resolution to about 2000
If you look over here in that condition
On the spot where we turned on the render setting
Press on the IPR
You can see it being rendered
But unlike the current smooth viewing mode
You can see the stiff rendering, right?
The maya default render is
Smooth preview render
The preview mode is not
applied
Like so, the low poly trait of the original image
can be seen exactly the way it is
The default light is proceeded this way
But this is a very
classic way of lighting
We do not use it very often
If you want to be a rendering lighting artist
In this default light setting
the practice of developing drawings
should be done a lot
Thesedays, there are developed versions
There are many physics-based
renderers
So, we do not need to install much light
in order to make color
There are renderers that are capable of it
Like what I showed in the render setting
This arnold renderer
We will proceed with this
First, in the render setting
set the width and height depending on the computer specifications
the rendering might take long
Utilize half HD to set the image size
Set it to 1280x720
Set the system to GPU
Now, this is the GPU render
The processing speed is faster than CPU render
So we will use this
The quality is better with the CPU render
First, the processing speed is faster with the GPU render
So we will choose this
In this arnold render
the Camera AA should be
set to about 6
The lightings that we have previously installed
eliminate it completely from the Outliner
In this condition, where the menu set rendering has been completed
Over here on the right, there is a window called arnold
Click on Skydome Light over here
What this is
It creates a round earth-like environment
and uses the light to shine on the object over here
But it is gray now
We will overlay an image on to this Skydome Light
This is an image called HDRI
This one image
There is a default image that I've prepared
Let's open it up
HDRI map called Bonifacio Street
It is used in substance painter
It is the default HDRI map
First of all, install it
If so, like in the picture
exactly like this environment
We will apply it to the character
And if you look at the viewport
You might see Resolution gate
If you press on this
Over here, it shows the image size layout
that we have set
In this condition, move the camera around
Press IPR
Then, quite differently from the
maya software render that has previously been done
It seems to have better quality
For this, press number 1 and number 3
We will proceed with the rendering after applying all of it
But now, everything is good except for one thing
This part of the eye and nose is too shiny
So Rendering Editors
In Hypershade
We will get rid of the shiny part slightly
Choose either one of the eyes
In the rendering editor
Graph materials on selected objects
There's no need to find it
If we press this, we do not need to find it
In this condition
We will decrease the Specular Color
and
Lower the Cosine Power
as well as decreasing the Reflectivity
By doing this, it is more
It is not too shiny and looks nice
I like it this way but
the light seems too weak
So, click on this Skydome Light
and press on Ctrl+A once again
I will increase the Intensity to about 1.5
It is slightly bright, right?
And
Turn off the arnold renderview for a moment
And select this Skydome Light
Hold the Rotate Y part and turn it around
And set the light direction nicely
How is the light set?
If you press the IPR again
Arnold renderview will pop up again
Looking from this arnold renderview
We wil adjust the direction of the light
It will follow us, once we turn it around
I think that this is just good enough
It would be nice for you to
find your own preference
The nose seems too shiny but
In this condition
We want to render this bear
We are trying to do the rendering
If this background is rendered as well
It might be unclear to use it, right?
So after selecting Skydome Light
Press Ctrl+A
In the Attribute Editor
If you scroll down, there is a Visibility
I will set the camera to 0 in this Visibility
Then, alpha channel will move in
We can get a hold of only the character
So looking over here in the render
I mentioned alpha channel
If you press it, you can see black and white
It means that only the white part will be rendered
Project Folder Management and After effect Sequence Editing
Now, 24 pages of this
will be rendered by us
We will print out 24 pages
and through after effects or premiere
We will use this to
make videos as a result
How will we render this?
In maya, when setting a route and saving it
We use something called Set
We generate a Set
In the set, the rendering
sequence images will be inserted
Click on File, Project Window
What this is
It is a window to generate the overall Set
So create a certain folder
And the scene file in that folder will be saved here
Images will be saved here
Everything will be assigned
So, if we carry around that folder we have made
There is no worry for loosing the file
or not being able to find the route
So leave the default setting there
And just press New
That way, you can name the Set
I will name it as bearAni
And then choose the Location
So, in the background of the desktop
I will choose a Location
And if I press Accept
BearAni, which is the file that I've made
The folder will pop up
Everything in Project Window
is saved just the way it used to be
So, the asset will save
the bear files that we have created
Textures and animation scenes
will be saved over here
And if you do the rendering
The route that I have made, image
a file will go into it
Before the rendering
The animation file that was about to be rendered
In the Scenes folder, inside the project
We will save it over here
We have saved it
Now, the render setting
is what we will be working on
If you look at the bottom
It says Persp
It means we are looking through Persp camera
Take out the Camera from Create
You can see that a camera has been created over here
So Panels, Perspective, Camera
After doing so
with the newly made camera
We can arrange the animation layout again
or use the perspective as the way it is
If you have set the camera
It will say Camera1 at the bottom
Then this Renderable Cameras
will be changed to Camera1
Move it to the top and
File name prefic
bearAniWalk
I will set the image format as exr
And leave Color space as it is
For Frame, Animation ext
name,#,ext
The # stands for numbering
ext stands for format
So this # is set to Frame padding
And if it 3, the numbering pops up over here
It currently starts from 001
01 for 2
Usually, it is best if set to 4
The scene that is rendered with 4
doesn't go over 10,000 pages
4 would be good enough
If it seems to go over 10,000 pages then set it to 5
And for Start Frame
Since we worked on it from 0 frame
Set it to 0 End Frame 24
As I mentioned, the camera
I will scroll down slowly
Set it while you look through
In this condition, Render
Open up Render Sequence option box
What the Current Camera is
I set it as Camera1
Press on Camera1 Render Sequence
If you wait a moment, all 24 pages will be rendered
The rendering is finished
The exr files will be accumulated in the image folder
We will move this to after effects
and create a video with it
The Composition Settings
we have set it to 1280x720
Choose 1280x720 and Frame Rate 24
I will set it to 5 seconds
The duration is 5 seconds
And bearAni, image
When Importing this
Click on the very first image and
If OpenEXR Sequence has been clicked
You can Import it right away
But click right
from the Interpret Footage
What number is set for the Frame Rate
needs to be checked
It is different for every after effects setting
which is why it always needs to be checked
The area around it is too red
Like so, it's exactly 5 seconds
Copy 5 of it and click right, Keyframe Assistant
If you do so
Reduce each of it by one frame
Like so, a moving bear
animation has been completed
It's cute
Set it as background
in the screen size of your preference
However you want it to be
I like the hot pink color
It's overlapping
I will choose the color yellow
I will import it
Press on Ctrl+M
I will import it with H264
I will do an overview of what we learned in this lesson
First, we used scan line renderer
to look for the default lighting and rendering process
Moving on, we used arnold renderer
to set luxurious lighting and shadow
We have checked the difference between two renders
Lighting and rendering
completes the character and the overall atmosphere of the animation
It is an important process
Today, for the rendering
We have only scratched the surface but
We will be able to make a better result
futher on
Thank you for your effort to follow along the lesson
three-point lighting and arnold renderer three-point lighting spotlight, fill light, rim light Click Createl Lights Spot light to create default light
Fill light: A light used to make sure the shadow part isn't too dark Rim light: A light used to shine on the outer edges of the dark spot
Ambient Light is a light that is similar to an overall natural light Helps to differentiate day and night of a scene Arnold renderer
Set the image size to 1280x720 in Render Settings Insert 6 as a Renderer Camera AA value
Click on Arnold Lights Skydome Light Click on Skydome Light and press ctrl+A to insert 1.5 for Intensity value
Select Skydome Light and rotate the Rotate Y value to set the light direction Use Arnold RenderView to set the direction of the light
Click on Skydome Light and Ctrl+A From Attribute Editor-IVisibility, set the Camera value as 0
Project folder management&After effects Sequence Editing Set the route in maya and utilize Set to save it/Allow rendering sequence images to be insert
Insert name in File Project Window New Set In case of rendering, the file is saved to a previously created images folder
The animation file is saved to Scenes folder After effects sequence editing Click on Create Cameras Camera to create a new camera
When selecting Panels Perspective Camera 1 the newly created camera can be used to set layout
Insert file name in File name prefic modify to name,#,ext for Frame, Animation ext
Insert 0 for Start Frame and 24 for End Frame When Importing, click on the very first image and select OpenEXR Sequence
Copy 5 of them and click on Keyframe Assistant Sequence Layers to complete the moving character animation
