How to rig your Vtuber model with Live2d

[00:00] hi guys it's kapaka in this video i'll

[00:03] be talking about how to use live2d to

[00:05] animate your youtuber model

[00:07] in the last two videos i went over how

[00:10] to draw

[00:11] and cut up your youtuber model you'll

[00:13] want to have your photoshop file ready

[00:15] for live 2d import

[00:16] so if you aren't sure check that

[00:18] everything is formatted correctly in

[00:20] this video live 2d might seem daunting

[00:23] at first but

[00:24] so is learning how to use photoshop or

[00:27] whatever drawing program it is you use

[00:30] what i'm trying to say is live 2d is

[00:32] simple

[00:33] once you understand the basics and the

[00:35] tools

[00:36] let's get started firstly open up live

[00:39] 2d

[00:39] and import your photoshop file by

[00:42] dragging and dropping

[00:44] and select the highest resolution to

[00:46] view your model in

[00:48] before we go any further let me

[00:50] introduce you to the layout of live 2d

[00:53] parts show all the parts of your model

[00:56] which are also called

[00:58] textures and how they're layered from

[01:00] front to back

[01:02] the farmer is where you'll be working

[01:04] most of the time

[01:05] it shows the deformer hierarchy and

[01:08] where you create deformers that

[01:10] bend your model to create movement

[01:13] inspector is where you control the

[01:15] clipping id opacity and blend mode

[01:18] of your textures parameter is

[01:21] also where you'll be working most of the

[01:23] time it has the parameters that your

[01:26] face tracking program will use and here

[01:29] you set the keyframes that

[01:30] animate your model canvas

[01:34] shows your model and this is where you

[01:36] interact with the deformers

[01:38] use the scroll wheel to zoom in and out

[01:41] and press the space bar

[01:43] and click to pan around secondly

[01:47] select everything in the deformer window

[01:49] and generate a mesh

[01:51] select the standard preset and close the

[01:54] window

[01:55] next create a texture at this set the

[01:58] width and height dimensions to match

[02:00] your photoshop document

[02:01] the maximum will be 2048

[02:05] by 2048 pixels for the free version

[02:08] of live 2d

[02:12] set the margin to 30 pixels and select

[02:15] automatic layout click on any one

[02:18] texture

[02:19] and check that the skill is 100 percent

[02:23] if it isn't the image will look

[02:25] pixelated

[02:26] click ok

[02:30] and now save your live 2d progress

[02:35] thirdly

[02:36] sort parameters into photos so that is

[02:39] neither to work with

[02:40] create seven folders for the face eye

[02:44] eyeball brow mouth body and move

[02:48] drag the parameters into the

[02:50] corresponding folders

[02:53] you can add more parameters for

[02:56] additional animations

[02:57] click on the new parameter button and

[03:00] give it a unique name

[03:01] then click ok examples of additional

[03:04] parameters are

[03:05] arms legs ears wings or tails

[03:09] key forms are poses that you set as the

[03:12] maximum

[03:13] and live2d will animate the range of

[03:15] motions between these maximums

[03:18] you can also set key forms in between

[03:20] for specific

[03:21] transition points select the deformer

[03:24] and use the first two buttons to create

[03:26] key forms

[03:27] or the fourth button to place a specific

[03:30] key form next let's start looking at

[03:33] deformers

[03:35] you can think of deformers kind of like

[03:37] folders

[03:38] a deformer will bend all the things

[03:40] inside it

[03:41] this includes textures and other

[03:43] deformers

[03:45] there are three main type of deformers

[03:48] the most common is the warp deformer

[03:51] select the textures you want to group

[03:53] together and create a warp deformer

[03:55] this deformer controls all the textures

[03:58] selected

[03:59] to animate movement select a key form on

[04:02] the parameter

[04:03] and move the green controls around to

[04:05] move stretch

[04:06] and squish parts of the textures warp

[04:10] deformers are useful

[04:11] for x y z parameters

[04:14] the second is the rotation deformer

[04:17] select the textures you want to control

[04:19] and create a rotation deformer to place

[04:22] the rotation deformer precisely

[04:24] you can move the center of rotation and

[04:27] tail

[04:27] by pressing the ctrl key and clicking it

[04:31] to animate movement select the key form

[04:33] on the parameter

[04:35] and move the center and tail without

[04:37] holding ctrl

[04:38] to move and rotate the textures

[04:42] rotation deformers are useful for joints

[04:45] and sometimes z parameters

[04:48] the third is the deform path

[04:51] select one texture and place a dot in a

[04:54] line along the length of the texture

[04:56] to animate movement select the key form

[04:59] on the parameter

[05:00] and move the dots to deform the texture

[05:04] the form paths are useful for eyes mouth

[05:08] and hair

[05:12] make sure you have a green key form

[05:14] selected

[05:15] when moving deformers or you'll just be

[05:18] editing your default model

[05:20] it's better to have more deformers than

[05:23] too few

[05:24] if the object moves in xyz parameters

[05:27] make sure one deformer for each

[05:30] parameter

[05:31] or make at least three deformers

[05:34] note that one parameter can control

[05:37] multiple deformers

[05:39] this is my template for the former

[05:41] hierarchy which is on the screen right

[05:43] now

[05:44] this is the simplified version of what

[05:46] my model uses

[05:47] the general layout is the same for

[05:49] everyone but the specific

[05:51] part deformers will depend on how you

[05:53] separated your parts

[05:54] and how many moving parts your model has

[05:58] next let's go over parameters and where

[06:00] to begin

[06:02] i like to break the broad parameters

[06:04] first before

[06:05] moving on to the more detailed

[06:07] parameters

[06:08] the order i took when rigging parameters

[06:11] was

[06:12] body move face eyeball brow

[06:16] eye and mouth i started with the broad

[06:19] parameters because

[06:21] it was the easiest to rig and if i

[06:23] realized that i had separated the body

[06:25] parts incorrectly

[06:26] i could replace them easily the more

[06:29] detailed parameters

[06:31] are more work but if you separated

[06:34] everything

[06:35] it's unlikely that you need to replace

[06:37] anything

[06:38] lastly once you're finished with all the

[06:40] parameters

[06:41] we have to add physics under modeling

[06:44] click on open physics click

[06:48] add and name it for example hair physics

[06:52] select the input preset as your head

[06:54] input

[06:55] the physics model preset as your hair

[06:57] length and click ok

[06:59] click on output settings and add your

[07:01] hair parts

[07:03] by following these steps you can also

[07:05] add physics to the movement of your

[07:07] clothing and

[07:08] chest too on the preview you can click

[07:11] and move the cursor

[07:12] to test how the physics looks like

[07:16] finally we are ready to export your

[07:18] vtuber model

[07:20] under file click export for runtime

[07:24] export as a mod 3 file check that

[07:27] physics is checked and click ok

[07:31] create a new folder and save it there

[07:34] this folder is your vtuber model

[07:36] fully rigged and ready to be imported

[07:38] into your face tracking program of

[07:40] choice

[07:42] and there you have it your very own

[07:44] feedtuber model

[07:45] you just have to find a face tracking

[07:47] program but

[07:49] fear not i'm making a video comparing

[07:51] all the free face tracking programs for

[07:53] live 2d

[07:55] so i know i skipped the rigging of the

[07:57] individual parameters

[07:59] but there are 30 minute tutorials on

[08:01] youtube for every single one already

[08:03] i wanted this video to be a tutorial on

[08:06] the basics of live 2d

[08:08] and an outline of the steps you need to

[08:10] take from start to finish

[08:13] i hope you found this helpful leave any

[08:15] questions

[08:16] in the comments and i'll be sure to

[08:18] answer them thanks for watching
