How To Make a 2D VTuber Model | Art - Rigging - Tracking [All In One Guide]

[00:00] I'll try to go through everything in

[00:01] this video from modeling, rigging,

[00:03] tracking, and recording. What software

[00:06] is needed to make a VTuber? First, for

[00:08] art program, it can be any application

[00:11] as long as it can export as Photoshop

[00:13] file program like Photoshop, Cliff

[00:16] Studio Paint or Procreate will work just

[00:19] fine. Second, live 2D cubism to rig the

[00:22] model for the art program. You can

[00:24] download the software at

[00:26] robblifeet2d.com

[00:28] English. It costs around 14,000 yen or

[00:32] 96 USD per year or 2,000 yen or 14 USD

[00:37] per month by the time of recording. I

[00:40] downloaded the 42day free trial version

[00:43] and managed to finish rigging my model

[00:45] before the trial end. So, unless you're

[00:47] going to be using this application for a

[00:49] long time, I suggest you try out the

[00:51] 42-day trial first. Third, B2 Studio.

[00:55] After you finish rigging in Live 2D, you

[00:58] can import the file to V2 Studio to

[01:00] track your facial expression with your

[01:02] model. It is free on stream, but cost

[01:05] around 6.7 USD to remove the watermark

[01:08] using webcam.

[01:10] Otherwise, you can use an iPhone and

[01:13] install the app to link to your iPhone

[01:15] camera. The iPhone version would cost

[01:18] for the US to upgrade to Pro. If you

[01:21] don't upgrade on the iPhone, the

[01:23] connection between iPhone and PC will be

[01:26] lost every 10 minute or so. The benefit

[01:28] of using an iPhone instead of a webcam

[01:31] is that it can track the facial motion

[01:34] more accurately than a webcam does.

[01:37] Fourth, OBS is a software for live

[01:40] streaming or recording videos. I highly

[01:43] recommend this software because it is

[01:45] free and what most people use. It can

[01:48] record models from V2 Studio and

[01:50] recognize a transparent background.

[01:53] Overall, this is what you need and how

[01:55] much it costs to make and use a V2

[01:57] model. Mainly does cost you money if you

[02:00] want to go professional, but if you want

[02:02] to just test it out, you can try using

[02:04] all the trial version. Now, I'll go over

[02:07] what asset you need and how to use the

[02:10] software. If you don't want to learn

[02:12] what to draw and skip to the rigging

[02:14] tutorial. I drew this model for free

[02:17] that you can use. I tried to make this

[02:20] model as simple and easy to rig as

[02:23] possible so that we can test it out

[02:25] together. Link is in the description.

[02:28] You can use this model for anything

[02:30] after it as well. Art program. First

[02:33] thing that we have to decide is what

[02:35] canvas size will it be on the screen is

[02:38] how many pixel for a small avatar half

[02:41] body full body super detail and alter

[02:45] detail is the file that I gave for the

[02:48] test is48x48

[02:52] pixel wide it is enough if you just

[02:55] using it to stream on the corner since

[02:58] you don't need a leg for that just need

[03:00] your upper hand meanwhile This full body

[03:03] model that I've been using to stream is

[03:06] 4,96 pixel x 8,192

[03:11] pixel. You can see how far you can zoom

[03:14] in and out and how detailed it is. Now

[03:17] it's time to start drawing. Start off

[03:19] with sketching symmetrically. You can

[03:22] make a model distorted, but it would be

[03:26] harder to rig. When we start drawing in

[03:30] detail, we need to make sure that we

[03:32] separate the body parts in different

[03:34] layer. Here are the different parts.

[03:37] Different hair bangs, left and right,

[03:39] separated face features like the blush,

[03:43] nose, eyebrows, eyelashes, upper eye

[03:48] skin that we're going to be using to

[03:50] cover the eye when we move later on.

[03:53] Lower eye skin as well.

[03:56] I shine the pupil, the eyeball,

[04:00] upper lip,

[04:02] upper mouth skin to cover the what's

[04:06] underneath it. Lower lip, lower mouth

[04:10] skin, the mouth inside,

[04:13] face line, face skin, and ear.

[04:18] And then we got the clothes, the

[04:21] neckline, neck skin, the neck shadow,

[04:25] body, clothes behind the body, hair

[04:28] behind the body. Make sure to name the

[04:31] layer so it doesn't get confusing later

[04:33] on. Label the left and right side of the

[04:35] body part as L underscore and R

[04:38] underscore, or you can just type left

[04:41] and right. The line art and the color

[04:44] should be combined when you finish

[04:46] drawing. Like the arms should just be

[04:49] the arm layer. The hair should just be

[04:52] the hair except for the lip line and the

[04:56] face line art. Those should be

[04:57] separated. Now, this part is optional.

[05:00] We can draw a mask to erase the face

[05:04] line art during rigging when the

[05:06] character faces a different direction.

[05:09] You can use an airbrush to make this

[05:11] mask and then turn off the visibility.

[05:14] As for the face shadow, at the moment it

[05:17] look like a mess because it's out of the

[05:19] border. But don't worry, this is

[05:21] intentional since most art program have

[05:23] the ability to use clipping mask. When I

[05:26] click on the layer and turn on clipping

[05:28] mask, the shadow will only be inside of

[05:31] the layer underneath. Now it's not

[05:34] messy. And during the rigging, using a

[05:37] clipping mask will make the shadow look

[05:39] pretty dynamic. Then proceed to change

[05:42] the shadows blending mode into multiply.

[05:46] What multiply does is that it removes

[05:48] the white color from the layer that you

[05:50] set it to. This is what a lot of digital

[05:53] artists use to make easy shadow. And

[05:56] that's it for the main parts of the

[05:58] model. Here are question that I had

[06:00] while running like what about different

[06:03] clothes or expression. You can rig to

[06:06] change expression like blushing, crying

[06:10] or draw extra hand that turn on and off

[06:12] later. If you want those part in, you

[06:15] can draw those part and then turn off

[06:17] the visibility for now. And now we're

[06:19] done. Save the file as Photoshop file

[06:22] and it's time to head on to the next

[06:24] program or you can take a rest, get some

[06:27] snacks and come back later.

[06:29] Live 2D cubism. Overall, I'll be going

[06:32] in these orders. Interface, mesh, tools,

[06:37] parameter for rigging, physics, then

[06:40] exporting. The timestamp will be in the

[06:43] comment if there are specific parts that

[06:45] you want to skip to. Open up live 2D

[06:48] cubism.

[06:49] Click new and on this box drag the

[06:53] Photoshop file in. It will ask what

[06:56] resolution for displaying the model

[06:58] image. This doesn't affect the actual

[07:01] model. So just click one out preview.

[07:07] Now you see this interface but make sure

[07:09] that you're in the correct interface.

[07:11] Over here, there will be a dropown that

[07:13] you can pick modeling, animation, form,

[07:16] animation. Make sure you're in the

[07:18] modeling because this is where we'll

[07:20] begin rigging. All right. Now, looking

[07:23] at the part window, this is where all

[07:25] layers that you had in the art program

[07:27] will be shown. The part window will be

[07:30] on the top left of the screen by

[07:32] default. However, if you can't find this

[07:35] window there, go to the window menu here

[07:39] and it will show all the windows that

[07:41] are available that you can turn on and

[07:43] off if you can't see it. Back to the

[07:47] model, the recognizable difference is

[07:49] that my shadow is not being clipped

[07:51] masked. We'll need to reassign all the

[07:54] clipping mask again. Go to where the

[07:56] shadow is in the parts. Once you click

[07:59] on the shadow part, the setting for this

[08:01] part will be shown in the inspector

[08:04] window. This is where you can edit the

[08:06] name and clipping ID of the part. Go to

[08:09] the pop- down of the clipping ID and

[08:12] find the body part that the shadow is

[08:15] going to be clipped to. In this case,

[08:17] the neck. Once selected, this shadow

[08:21] part will be clipped inside.

[08:23] Now repeat this process for the other

[08:26] shadows or part that have to be cliff

[08:28] too like the face shadow and the

[08:31] blushes.

[08:34] Now before I move on, if you have edited

[08:37] or drawn in new parts in the art program

[08:40] and want to update it here, you can just

[08:43] drag the newly updated Photoshop file

[08:46] into live 2D over here and it will give

[08:50] you an option to create new file or

[08:52] choose the already existing file. Click

[08:55] that and after that the part that have

[08:58] the same name will be replaced and the

[09:00] part with names that didn't exist before

[09:03] will be added in a new folder. So you

[09:05] don't need to be afraid if you want to

[09:07] make changes to your model. Another

[09:09] window I want to explain is the project

[09:12] window. It looks similar to the parts

[09:15] window but it's there for a different

[09:17] purpose. You can see what Photoshop file

[09:20] is in the current live 2D model. The

[09:22] useful thing about the project window is

[09:25] that if you accidentally delete a part

[09:28] in the parts window and you want it

[09:30] back, you can head to the project window

[09:33] to find it and add it back in by

[09:36] right-clicking and clicking create art

[09:39] mesh. This part will then be readited

[09:42] into the part window. Now that you have

[09:44] gotten the model in live 2D, don't

[09:46] forget to save. Press Ctrl S on your

[09:50] keyboard or go to file save as. The file

[09:54] for editing in live 2D is C O file. So

[09:59] if you're tired and want to edit another

[10:01] day, this is what you want to open to

[10:04] edit it again. And with that, we move on

[10:07] to the mesh. To be able to make the part

[10:10] flexible, you have to give every parts a

[10:13] mesh first. What is a mesh? a mesh or

[10:16] these spiderweb looking thing. When you

[10:19] move the dot, it will move the image

[10:22] that it's assigned to. This is what help

[10:25] the make part looks a lot more flexible.

[10:28] Now to add a mesh, click on a part. Then

[10:32] using this two tools up here. The first

[10:34] one is called manual mesh edit. You can

[10:38] use this to add mesh point one by one.

[10:41] However, it's very inefficient. So,

[10:43] we're going to be using the second tool

[10:46] more often, the automatic mesh

[10:49] generator. Instead of creating a mesh

[10:51] point by point, the program will do it

[10:53] for you. When pressed, the toolbox will

[10:56] appear. You can choose from the press

[10:58] and drop down standard deformation

[11:01] little deformation heavy. The less

[11:04] certain mesh is, the less fluidity there

[11:08] will be.

[11:09] So I suggest using deformation heavy for

[11:12] important parts like the face, the eye,

[11:16] the hair, the lips and standard for

[11:19] parts that won't move as often. Now make

[11:22] sure that every part you have in the

[11:24] file has a mesh by selecting all the

[11:27] parts and clicking on the automatic mesh

[11:30] generator.

[11:33] Now we want the face part and the face

[11:35] line art part to have the same exact

[11:38] mesh so that when we move one the other

[11:42] move the exact same way. If it have a

[11:44] different mesh it will not sync with

[11:47] each other. So create automatic mesh

[11:51] then go to manual mesh edit.

[11:54] Select all of the mesh and on your

[11:57] keyboard press Ctrl C to copy all of it.

[12:01] Then click the shack button. Now we go

[12:03] to the faceeline arter parts. Click

[12:06] manual mesh edit and if there's already

[12:08] a mesh in there, select them all and

[12:11] delete it. Click by clicking the delete

[12:13] button. Then press Ctrl +V to place what

[12:17] we just copied in. And after that, click

[12:19] the check button. And now these two

[12:22] parts have the exact same mesh. Do the

[12:25] same for the neck. If you separated the

[12:28] line art and the skin,

[12:32] if you're done with adding mesh for the

[12:33] parts, we can move on to edit texture

[12:36] atlas. This is what texture atlas look

[12:39] like. This is where we'll lay all the

[12:41] parts into a page for export. When press

[12:44] the edit texture atlas button, it will

[12:47] ask name, size, and default layout. For

[12:50] the name, you can just leave it as

[12:52] texture atlas one. For the size, it

[12:55] depends on how big your canvas size is.

[12:58] Once again, there's different pixel size

[13:01] for each one. Recommend that you make it

[13:04] square size. If you're using this test

[13:06] model, you can just use48

[13:09] *48.

[13:11] For default layout, picked do not place.

[13:14] And now we go okay. And this is a window

[13:17] that will appear. On the right here is

[13:20] the model image list. It is all the

[13:23] parts that you have in your model.

[13:25] Double click on the part to place it in.

[13:28] You can move it around in this texture

[13:30] atlas. What we want to do here is place

[13:33] the textures into this sheet without

[13:36] rescaling and without overlapping the

[13:38] parts.

[13:40] [Music]

[13:41] Now, if all the parts aren't enough to

[13:44] fit in a single page, you can add

[13:46] another page by clicking the add texture

[13:49] button up here. With the second page,

[13:52] you can place the remaining parts that

[13:54] couldn't fit in.

[13:58] [Music]

[14:01] And once you're done, press okay.

[14:04] As said on the bottom right, if you

[14:06] press T on your keyboard, you can swap

[14:08] between what the quality look like

[14:10] before and after texture atlas. If

[14:13] nothing change when you press the T

[14:15] button, that's mean you did a great job.

[14:18] But if it looks different and it looks

[14:21] weirdly wonky, then maybe you

[14:23] accidentally overlap some parts or

[14:26] descale the parts to make it look a lot

[14:29] more blurry. Now, after you're done with

[14:31] texture atlas, we move on to the other

[14:33] tools you use to rig your model.

[14:36] Starting with the warp deformer, select

[14:38] on any part and click on the warp

[14:40] deformer. This panel will pop up. Just

[14:43] click create. Now, there will be this

[14:45] green grid box. This is a deformer. If

[14:49] you move the point on this deformer, it

[14:51] will move the mesh below. You'll be

[14:53] using this tool a lot. Now, when you

[14:55] click on the deformer, the setting for

[14:57] the deformer will appear on the

[14:59] inspector. You can redeem deformer here.

[15:02] Trust me, you won't regret naming things

[15:04] since there will be a lot of deformers.

[15:08] Another thing in the inspector is

[15:10] changing the number of division. So if

[15:13] you want to make there be more division,

[15:16] you can play around with these numbers

[15:19] and it will make you have more control

[15:22] points. To see every deformer that has

[15:25] been created, you can look at this

[15:27] deformer window on this bottom left.

[15:30] This is like the folder system for the

[15:32] deformers. It help you see and rearrange

[15:35] what deformer is in each other. It's a

[15:38] very helpful window and you'll be using

[15:41] it a lot. The reason to use deformer to

[15:44] wreck instead of controlling the mesh

[15:46] directly is because you can create a

[15:48] deformer on another deformer. It works

[15:51] quite like a folder. Like I can have a

[15:54] deformer for the eye and another

[15:56] deformer for the face turning which make

[15:59] it to where the eye deformer which is

[16:02] under the face deformer will get

[16:04] deformed along as well. And by stacking

[16:08] things up like this, that's how we make

[16:10] our model become alive.

[16:12] Next is the rotation deformer and

[16:15] rotation deformer creation tool. Just

[16:17] like the warf deformer, it will control

[16:19] the mesh and be put in the deformer

[16:22] window. However, instead of moving the

[16:24] points, you rotate instead. The

[16:27] difference between rotation deformer and

[16:29] rotation deformer creation tool is that

[16:32] the first one will spawn the rotation

[16:34] deformer in the middle of your parts

[16:37] while the second one lets you create the

[16:40] rotation deformer wherever you want. And

[16:43] that's the tree deformer tools. Now we

[16:46] head to arrow lasso and brush tool which

[16:49] is pretty self-explanatory.

[16:51] You use the arrow to select different

[16:54] tools. You use the lasso to select

[16:57] multiple things at once and you use the

[17:02] brush selection to select things like a

[17:04] brush.

[17:06] And now we go to deform pad edit. This

[17:11] allows you to make a part used to edit

[17:13] the mesh in a line easily. This is great

[17:16] for the lips, the eyelash and the

[17:18] eyebrow. Now we move on to actually

[17:22] rigging the model. For that knowing the

[17:24] parameter is very important. When you go

[17:28] to parameter window you can see these

[17:30] defaults parameter given. These

[17:33] parameters are empty and you'll have to

[17:35] fill them up. Let's start with angle C.

[17:38] This is for rotating the head. So what

[17:41] we have to do is select all of the head

[17:44] and create a rotation deformer creation

[17:48] tools. Now drag the rotation deformer

[17:51] from the shin to the head.

[17:54] Now go to the arrow tool instead. Click

[17:57] on angle C and press this tree green dot

[18:01] button. They are the key forms. The

[18:03] middle is looking straight. The left is

[18:07] for rotating to the left and the right

[18:10] is for rotating to the right. So when we

[18:12] move the red dots around to the left, we

[18:15] can rotate the deformer to the left. And

[18:19] when we move the red dot to the right,

[18:22] we can rotate the deformer to the right.

[18:25] And now when we move the red dot around

[18:27] the parameter, it will rotate the head

[18:30] around as it should. And this is how

[18:34] parameters work and what we're going to

[18:37] be doing for the rest of it. To

[18:39] summarize again, select all parts and

[18:42] create a deformer. Click on the

[18:44] parameter. Add key forms. Go to the key

[18:49] form you want to edit. Move the deformer

[18:52] around. And there we go. That's how you

[18:55] rig every part of the model. Now, angle

[18:58] C is the easiest one. Let's move on to

[19:01] the harder ones like angle XY. Angle X

[19:06] is for looking left and right, while

[19:08] angle Y is for looking up and down. Now

[19:11] we want the model to be able to look

[19:13] towards the upper corner as well like

[19:16] upper left, upper right, lower left or

[19:18] lower right. To do that we have to

[19:20] combine angle X and Y by pressing this

[19:23] link button right here. When we press it

[19:25] the parameter will now look like this

[19:28] graph. Now let's get to rigging by first

[19:30] selecting all the head parts and create

[19:33] a new deformer. Call it BF angle XY

[19:38] head. Then select the angle XY parameter

[19:41] and click this three green dot icon

[19:43] again. Go to the left in the parameter

[19:47] and make sure you snap to it by right

[19:49] clicking. Right clicking is how you snap

[19:51] to these dots. Now turn the face to the

[19:55] left. It will look pretty bad right now

[19:57] cuz we have a lot of adjusting to do.

[20:02] And after you're done turning it left,

[20:05] you'll want to turn it right.

[20:09] And now your face is turning. It doesn't

[20:13] look so good right now though because

[20:15] you want to move individual facial

[20:17] features to create more dimension like

[20:19] the nose. So we can go to the nose and

[20:22] create another deformer. Call it df

[20:27] anglexy

[20:29] nose. And then when you look to the left

[20:33] the nose may protrude a bit more.

[20:36] [Music]

[20:40] And now you're going to write it may

[20:41] protrude a bit more as well. So now it

[20:44] looks better.

[20:46] And do the same for all the other side

[20:48] as well. Looking to the top

[20:51] and looking to the bottom. Just adjust

[20:55] it around. This will take quite some

[20:57] time. And then after you're done with

[21:01] left, right, top, bottom, instead of

[21:04] working on the corners right away, we

[21:07] can have the program try to work on it

[21:09] first. Go to the center of the

[21:12] parameter. Then in the menu, click

[21:14] modeling parameter, set the size corner,

[21:19] and okay. So the software have now

[21:23] created the corners for you. When you

[21:26] move around the angle XY parameter, the

[21:30] model will face towards that direction.

[21:32] You can fix them manually if it looks

[21:34] bad though. And with a lot of adjustment

[21:37] and on a lot of time, angle XY is kind

[21:41] of dumb.

[21:44] Now remember the face mask, we can use

[21:48] that here to make the face line

[21:50] disappear a little at a certain angle.

[21:53] Turn on the visibility of the mask.

[21:55] Second, select the face line art and on

[21:58] clipping ID, make it clip to the face

[22:01] mask.

[22:02] [Music]

[22:04] Then we click this reverse mark button.

[22:07] Turn the opacity of the face mask to

[22:10] zero.

[22:12] We can create a deformer for the mask

[22:15] and in angle XY add the key form and

[22:18] move the mask around. This isn't

[22:20] necessary, but I see most Btuber use

[22:23] this technique. You can check out the

[22:26] preview of the model by going to the

[22:29] menu modeling physics settings. Ignore

[22:33] the weird setting on the left right now.

[22:35] Looking at the screen on the right, when

[22:37] you click and hold the screen, the model

[22:39] will look toward your cursor. This is

[22:41] where you can go to check whether your

[22:43] model is working or not. Moving on to

[22:46] the eye parameters.

[22:48] First, we'll only be doing the left eye.

[22:51] And then after we're done rigging the

[22:53] left eye, we'll then copy paste the left

[22:56] eye to the right and flip it. So that

[22:59] will be less work to do. Looking at the

[23:02] IL open here, you will see that the left

[23:05] is zero and the right is one. Previously

[23:09] in angle X, Y and Z, the parameter can

[23:13] go to the negative to indicate left or

[23:16] bottom and positive to indicate right or

[23:19] up. For the eye, however, there's only

[23:21] close and open. Close being zero and

[23:24] open being one. Now, if you want a

[23:27] surprise eye, you have to increase the

[23:30] parameter to 1.3 so that the eye would

[23:34] widen more. To change that, you can

[23:37] right click the parameter and edit.

[23:40] Change the maximum to 1.3.

[23:45] Starting with the eyelash, select the

[23:48] eyelash and since it's a line instead of

[23:51] a deformer, we'll use the deform pad

[23:53] edit tool instead. Click along the

[23:56] eyelash to create control points. These

[23:59] control points will let you move the

[24:01] eyelash freely. Go to the arrow tool on

[24:04] the box over here. Type one so we make

[24:07] sure we're in the one and add key form

[24:11] at this exact location. And instead of

[24:13] clicking the three dots in the

[24:15] parameter, click the two dots instead.

[24:18] So now zero is I closed, one is I open

[24:24] normally, and 1.3 is I being wide. And

[24:29] we just move it around at these

[24:31] locations.

[24:34] And now we go to the upper eye skin.

[24:38] Create a deformer for the upper eye

[24:40] skin. and add the same key form to the

[24:43] parameter

[24:45] 0 1 1.3 and drag the deformer so that it

[24:49] covers the eyeballs when the eye is

[24:51] closed or open.

[24:53] [Music]

[24:54] Now go to lower eye skin and do the same

[24:58] process

[25:01] and after that that's it for open

[25:04] parameter.

[25:06] Next is IIL Sumal. Here we can make the

[25:10] blush more visible. Go to the blush part

[25:13] and turn it on if it's off. Now add two

[25:16] key forms using the two green dot button

[25:19] here. On zero we'll turn the opacity of

[25:22] the blush to zero. And on one we'll turn

[25:26] the opacity to 100. So that's how we

[25:30] make it seems as if the model is

[25:33] smelling. Next is eyeball XY.

[25:36] X is for looking left and right. Y is

[25:40] for looking up and down. Connect the X

[25:42] and Y together so that we can look at

[25:44] the corners as well. Select the pupil

[25:47] parts and create a new deformer. Click

[25:50] on the three green dots and start moving

[25:53] the pupil around. This is basically the

[25:56] same thing we did for face turns of

[25:59] angle XY timeline.

[26:03] [Music]

[26:05] And there we go. And then regrue the

[26:08] eyebrows. Create a deformer for eyebrow

[26:10] Y for moving up and down.

[26:15] And another deformer for bro L form.

[26:19] Negative one is sad, zero is normal, and

[26:23] happy is one. We can just delete bro

[26:27] angle and bro X because YouTube Studio

[26:31] doesn't really detect eyebrow moving

[26:34] left and right or bro angle. Also, you

[26:37] can make a deformer for the entire eye

[26:41] and move it around ankle X line to see

[26:44] if different direction the eye looks

[26:46] good and or not. Okay, now that your

[26:49] left eye is nice and done, we're moving

[26:52] on to copy pasting it to the right.

[26:55] Select all of your right eye asset and

[26:58] just delete them cuz we don't need them.

[27:03] And then select all of your left eye,

[27:06] copy paste.

[27:08] [Music]

[27:11] Now after you're done copy pasting it,

[27:13] go to modeling, edit form, reflect,

[27:18] click reflect horizontally, then click

[27:21] okay. Now we managed to create the right

[27:24] eye. Okay, we have to transfer the

[27:28] parameters from left to right as well.

[27:31] Starting with IIL open, click the number

[27:34] box and choose change.

[27:38] Go to IR open parameter. Now when you

[27:42] move the IR open parameter, it should be

[27:46] the right eye. Now also do for same for

[27:49] eyebrows. Click BR L Y change to Bro R Y

[27:56] and also Bro L form change to bro R

[28:00] form.

[28:02] [Music]

[28:04] Now as for the eyeballs, it's now

[28:07] looking at the opposite direction. In

[28:10] eyeball X parameter box, click adjust

[28:13] instead. In value after change, put in 1

[28:18] 01

[28:21] and click okay. Now the eye should look

[28:24] the same way. If it looks weird, you can

[28:27] adjust it around. If you edited the IL

[28:30] open parameter to 1.3 for surprise eyes,

[28:34] don't forget to do the same for IR open

[28:36] as well. And you can also make a

[28:39] deformer for the eye shines when it

[28:41] looks at different angles as well. Make

[28:44] sure to rename the folder into I write

[28:47] instead. And we want to rename

[28:49] everything else in this folder from left

[28:52] to right as well. To change it easily,

[28:55] go to edit search and replace on

[29:00] condition. Type L underscore or left.

[29:04] And now we have to select all of the

[29:05] copied left eye to make sure that it is

[29:08] the copy part. on the left parent column

[29:11] it should say that the parent is R I

[29:15] select all of it and on the bottom here

[29:18] before replacement as L underscore and

[29:21] after replacement to R underscore then

[29:24] click replaced now all the left part

[29:27] that got copied will be named right so

[29:30] that it won't be confusing but now the

[29:32] eye should be completed

[29:34] now we move on to lip sync if you manage

[29:38] to come this far then the mouth isn't so

[29:40] different. Link the mouth form and mouth

[29:44] open together. The bottom middle 0 0

[29:48] should be mouths closed. Up one should

[29:52] be mouth open normally. To the left in

[29:55] negative is sad and to the right is

[29:59] happy. Now use the deform pad edit tool

[30:02] for the lip line and move it as you

[30:04] want. You don't have to make it exactly

[30:08] the same. and can go freestyle with it.

[30:14] After you move the lift, then you move

[30:16] the upper lip skin to conceal the mouth

[30:18] inside. You can also use the deform pad

[30:21] edit for the mouse skin as well by

[30:24] creating the pad along the lips. And

[30:26] then timelapse. It's going to take some

[30:29] times to move things around, but I think

[30:32] now you get what to do. It's all the

[30:36] same process, just um different parts.

[30:39] And tada, we we did it. The mouth.

[30:44] And moving on to body X, Y, Z. Body X is

[30:49] moving the body to left and right. And Y

[30:52] is moving body up and down. And C is if

[30:55] you tilt your body like the hips and the

[30:57] shoulder. And since we don't have the

[31:00] lower body here, we will just ignore

[31:03] body scene. Now go to the deformer

[31:05] window, collapse the deformer tabs and

[31:09] select every part. Now make one big

[31:12] deformer and call it deformer_bodyxy

[31:18] underscore body. Link the power meter

[31:21] together. Create key forms and move the

[31:25] deformer just a bit left, right, up, and

[31:28] down. Synthesize the corner. And now

[31:31] we're done with body X and Y. Next is

[31:34] the breeding parameter. This is a

[31:36] parameter that will play on

[31:38] automatically. Zero is normal, one is

[31:41] breed in. So select the body XY deformer

[31:45] and create another deformer on top.

[31:48] Create two key forms and on one just

[31:52] move the deformer up a little bit. And

[31:55] now when we check in the physics

[31:56] setting, we can see the character

[31:59] breeding automatically.

[32:01] And with that, you filled in all default

[32:04] given parameters. Don't forget to save

[32:08] extra segment. If your model has extra

[32:12] objects like different hand, a mic, or a

[32:15] pet that you want to be able to toggle

[32:17] on and off, you can make a toggle by

[32:20] creating a new parameter.

[32:22] Click on the plus button down here and

[32:25] name it whatever extra object that is

[32:28] and make the minimum zero. All there is

[32:31] to do is select those extra parts and at

[32:34] zero make it zero opacity and at one

[32:38] make it 100 opacity and that's it to

[32:41] create the toggle which we can use to

[32:44] later turn it on and off in YouTube

[32:46] studio. And there we go. The model will

[32:49] work. In fact, you don't even need to

[32:50] use this next step. But if you do, it

[32:53] will give your model some life to it.

[32:56] Physics. Physics is where the magic

[32:59] happen. It makes this turn into this.

[33:02] [Music]

[33:05] First, the hair is where there is most

[33:07] physics. Seect the front hair and create

[33:10] a deformer. Name it something like um

[33:13] DFP

[33:15] front hair. Our hair is really simple,

[33:17] so we can just use a default hair move

[33:20] front parameter. Negative one is sway

[33:23] left and one is sway right. To make it

[33:26] easy after moving negative one parameter

[33:29] go to modeling motion mirroring.

[33:34] Okay. And the program works on the right

[33:36] side of the parameters for you. We then

[33:40] continue to do the same for hair move

[33:42] side and hair move back. Go to physics

[33:46] setting. That's on the modeling physics

[33:49] setting. Now we don't ignore the setting

[33:52] on the left. Click the add dot dot dot

[33:54] button and name it hair

[33:58] input present as head input physic model

[34:01] presence as hair short. Then click okay.

[34:06] Now over here click the output setting.

[34:09] Then click the button add underneath it.

[34:12] Search for the parameter that we just

[34:14] made for this part. Check it on. Then

[34:17] click okay. Now you'll notice when you

[34:19] move the model left and right, there is

[34:21] now physics on your part. If you think

[34:24] it moves too much, then you can adjust

[34:25] the number in the pendulum setting down

[34:27] here. Tweak the number around and see

[34:30] what you like. Repeat this step for

[34:32] every parts that you want to have

[34:34] physic. Like this jacket strings doesn't

[34:37] have a default parameter, so we need to

[34:39] create a new one. Click on the plus

[34:41] button below the parameter and okay. and

[34:45] do the same thing where you sway it left

[34:47] and right and then add it into the

[34:49] physics settings. This time it's the

[34:52] body input.

[34:58] [Music]

[34:59] Now if you want the hair to flow more,

[35:02] we can create another deformer on top of

[35:04] the same hair part. Let's try this with

[35:07] the back hair. Then create a new

[35:09] parameter for another physics on the

[35:12] part.

[35:13] Move it a little on the tip of the hair.

[35:16] Then add this new parameter into the

[35:19] physics settings.

[35:26] Create another pendulum.

[35:28] Change the pendulum number of the new

[35:30] parameter to two. And now you can see

[35:34] this hair part moves more than before.

[35:36] If your model has many long hairs, you

[35:39] can add as much pendolums as you want to

[35:41] give it more physics. And with this,

[35:44] we're pretty much done with the model

[35:46] and can move on to exporting. To export,

[35:49] just go to file, export for runtime,

[35:53] export as OC3 files. Make sure the

[35:57] export physics setting file is checked

[36:00] on as well. Then press okay. Choose the

[36:03] folder that you want to save to. Create

[36:06] a new folder, named it, and save it

[36:09] there. This is what it should look like

[36:11] containing the texture atlas and

[36:13] everything. And we're good. We studio.

[36:17] Now we move on to the third needed

[36:20] program, YouTube Studio. This is it,

[36:22] guys. We're getting to the finish line.

[36:24] On PC, download the software from

[36:27] Stream.

[36:29] When you open the software, it will be

[36:31] blank. Double click on the screen so

[36:33] that you can open the menu. First button

[36:36] is for choosing the model. Click on the

[36:39] button and a character selection will

[36:41] appear on the bottom. The software

[36:42] already has a default model for you to

[36:44] test out. If you click on any of them,

[36:46] it will show that model up. To put in

[36:49] your own model, click import your own

[36:51] model and open folder. Now in the

[36:55] folders as open, copy paste the stuff

[36:58] that we exported from live 2D wherever

[37:01] you saved it.

[37:04] Now go back to the solver

[37:06] and click unload model to refresh.

[37:10] Clicking the model button again and

[37:12] scrolling through there should be a new

[37:14] model and choosing it. Our model will

[37:17] appear. There will be a popup to s auto

[37:19] setup. Okay. Now your model is in the

[37:23] server. If it's not moving, that would

[37:26] be because you have not connected a

[37:28] webcam or your iPhone yet. If you're

[37:30] using a webcam, first connect your

[37:32] webcam. Then click on the setting here.

[37:35] On the upper left, choose the webcam

[37:37] button. Then on the right, choose the

[37:40] blue choose camera button. Choose your

[37:43] camera and just click okay to whatever

[37:45] pops up. After that, it's done. Click

[37:48] the blue camera on button. It will

[37:51] calibrate your face.

[37:54] [Music]

[37:55] Close the calibrate. Now you have a

[37:58] working V2 model. And if you're

[38:01] connecting through an iPhone instead,

[38:03] first download V2 Studio on your iPhone.

[38:06] Go to setting and head down. You'll see

[38:09] connect through Wi-Fi or connect through

[38:11] wires. This is your preference. I picked

[38:14] Wi-Fi so that I can still charge my

[38:16] phone while streaming. Have your

[38:18] computer connect to the same Wi-Fi as

[38:20] your iPhone and it will automatically

[38:22] detect. Turn the button on and off if it

[38:25] doesn't work. Now, when you move or make

[38:27] facial expression while looking at your

[38:29] phone, the software on your PC will also

[38:31] detect that and follow along. Now that

[38:34] you connected it, it worked. There's

[38:36] still a little more things like changing

[38:38] the icon. To change the icon, you have

[38:41] to put an image into the same folder

[38:43] that contain your V2 file.

[38:48] Then back on V2 Studio, go to settings

[38:51] and on top click on it. Click on the

[38:54] image you put in the folder. Now the

[38:56] icon will be updated.

[39:00] Moving on to expression. This is how you

[39:03] can add a trigger if you have an extra

[39:05] object in your model. If you don't, then

[39:07] you can ignore this part. On the setting

[39:11] menu, you'll see this clap or button.

[39:14] Clicking on it will lead to the

[39:15] expression editor. Click on the blue

[39:18] button called expression editor. Then

[39:20] click create new expression.

[39:25] I have a mic on and off parameter for my

[39:28] own model. So I'll name it mic. Now then

[39:30] I scrolled all the way down where that

[39:32] parameter is. When we turned on the

[39:35] switch, it lets us adjust what that

[39:38] parameter will be stuck as. So I turn

[39:40] the slider all the way up and click

[39:43] save. Now going back, we have to add the

[39:46] hot key. So to tell the software how to

[39:48] trigger this expression, click on the

[39:50] plus button and a new hotkey panel will

[39:53] appear. Name it.

[39:56] Then click on the blue hotkey action

[39:58] button. Select set and unset expression.

[40:03] And then on the blue button under

[40:05] expression, select your expression.

[40:09] Key combination is if you choose a

[40:11] button on your keyboard, it will trigger

[40:14] the expression on and off. Then below is

[40:16] a screen button hotkey, which is what

[40:18] we'll be using. Click on the slot you

[40:20] want. Then make sure the switch on top

[40:23] of the hotkey setting for use screen

[40:25] button hotkeys is turned on. And now the

[40:29] screen there will be a button that you

[40:31] can click to trigger this expression on

[40:33] and off. Finally, how to get transparent

[40:36] background. First, on the menu, click

[40:39] the background button. On the list of

[40:41] backgrounds, scroll down until you see

[40:43] color picker. Select it. As you can see,

[40:48] under the color picker, there is a

[40:49] switch to turn on transparent in

[40:52] capture. What this does if if you turn

[40:54] it on when you connect this to OBS or

[40:56] other recording software you won't see

[40:58] the background only the model which move

[41:01] us over to the next and the last

[41:02] software OBS open the software that will

[41:06] be this window scenes if you can't see

[41:10] this window on the menu above docs is

[41:12] where all the window is kept at first

[41:16] add a scene by clicking on the plus

[41:18] button name it whatever you want it to

[41:20] be I'll name it YouTube scene

[41:23] Now in the next window called sources,

[41:25] click the plus button and select game

[41:27] capture.

[41:30] Click on create new and name it YouTube

[41:33] source.

[41:34] [Music]

[41:36] Now in the property here, change the

[41:38] mode to capture specific window. Then in

[41:41] the window, select YouTube studio. Under

[41:44] the check box, turn on allow

[41:46] transparency and turn off capture

[41:48] cursor. And there we go. The model

[41:51] should be shown in OBS. If you want to

[41:54] add a display behind the model, click

[41:56] the plus button again and select display

[41:59] capture.

[42:03] And now it will appear in the scene. You

[42:06] can click and drag the source up and

[42:08] down to arrange what appears on top and

[42:10] bottom.

[42:11] Now if you want to crop out the buttons

[42:13] on the side, you can right click V2

[42:15] source and select filter. Click plus

[42:18] button and select crop and pad.

[42:24] Now on the right, you can enter how much

[42:26] pixel you want to crop out to look nice

[42:28] and clean.

[42:33] And voila, it works. Now you can stream.

[42:36] Test it out just by recording to

[42:38] yourself first. Hit that record button

[42:40] and move around.

[42:43] [Music]

[42:49] Once you're done, stop recording and you

[42:51] can check where the file your recorded

[42:53] file is in the setting.

[42:57] [Music]

[42:59] Go to output and you'll see where the

[43:01] location is linked to. You can change

[43:04] the location to where you want it to be

[43:06] as well. And then you're actually done.

[43:09] That was a bunch of information that I

[43:12] wouldn't blame you for taking a break or

[43:14] even giving up. Now with this hard

[43:17] earned knowledge, what else can Live 2D

[43:20] use for? It can be used for animated

[43:23] movies. You can go farther with the

[43:25] animation feature and export as video

[43:28] instead. Make it like looping

[43:30] illustration for waiting screens or

[43:33] animating stickers and stuff. As for how

[43:36] to use the animation, here's a quick

[43:38] tutorial by going back to live 2D cubism

[43:42] in files, new animation.

[43:45] SDK Unity is what we use for V2 Studio.

[43:49] And just drag and drop the model you

[43:52] have into this window over here. And

[43:56] then drag it all the way down here.

[43:59] And now the model will be shown on the

[44:02] screen and all the parameters going to

[44:06] be here. And if you know how to edit

[44:08] videos, it's the same thing where you

[44:11] got the timeline and then you can adjust

[45:19] Thank you so much for watching the

[45:21] video. I've been planning to create this

[45:22] video for a very long time, but it takes

[45:25] some time to learn the software and make

[45:27] sure I didn't miss anything important

[45:28] myself since there are a lot to cover.

[45:31] If you want to commission me from

[45:33] drawing characters to rigging, I have a

[45:36] fiber page or you can just DM me on

[45:39] Instagram, Discord, X, etc. I hope the

[45:43] video wasn't too complicated. If there's

[45:45] any question, you can ask in the

[45:47] comments below. I stream from time to

[45:49] time on YouTube and Twitch. So, if you

[45:51] come to hang out, I'll be very happy.

[45:53] And thanks so much for watching. Hope

[45:55] you have a great day. Bye-bye.
