AI Summary

This video provides a step-by-step guide for aspiring VTubers on how to properly prepare and layer their character art in a PSD file for seamless rigging in Live2D Cubism. It emphasizes the importance of organizing layers correctly to avoid future hours of rework, covering key sections like the head (face, eyes, mouth) and body.

[0:11]
Goal: Art for Live2D Rigging

The video kicks off a tutorial series on becoming a 2D VTuber, starting with art setup. Live2D Cubism will be covered in future videos.

[0:21]
Prerequisites for VTubing

You need art of your VTuber model, cut into many little layers, exported as a PSD (Photoshop document) because Live2D Cubism only reads PSD files.

[1:04]
Why Correct Art Setup Matters

If art is not set up correctly at the early stage, rigging will be flawed and you'll waste hours going back to fix it.

[1:34]
Program Layer Limits

Check your art program's layer cap (e.g., Procreate has a cap). A complex model with many layers may be tedious in a program with a low limit.

[2:07]
Folder Organization Saves Time

Group layers into folder categories. The author uses: one main body folder, subfolders for body parts, another for features, and left/right sides. This keeps the file organized for rigging in Cubism.

[2:58]
Head: The Most Important Section

The head can be divided into: face, eyes, front hair, ears, eyebrows, nose, and mouth. Simpler rigs can keep the nose, front hair, and face as whole layers, but separating them further (e.g., hair into middle/left/right) allows a 3D effect.

[4:19]
Eyes: Extensive Separation Required

Eyes need many layers: sclera, top lid, bottom lid, iris, pupil, lashes, highlights, etc. Even simple models use multiple eye layers because rigging eyes is one of the hardest parts of Live2D.

[5:01]
Mouth: Simple Layers, Complex Rigging

Recommended mouth layers: top lip, bottom lip, tongue, inner mouth, top teeth, bottom teeth. Layer separation is simpler than the eyes, but rigging is equally complex.

[5:29]
Body: Limb Separation by Joints

The body is simpler; separate arms, legs, torso, and boobs (if present) into left/right portions. For more movement, separate limbs at joints.

[5:58]
Hair: Bangs vs. Rest

Non-bang hair gets its own folder; includes back of head and actual hair. Number of layers depends on hairstyle (solid piece vs. many strands).

[6:25]
Extras: Expressions and Accessories

Any extras (expressions, accessories, animal ears/tails) should be placed in their own folders within the main folder, wherever they are located.

Properly layering your VTuber art into a well-organized PSD file is the critical first step to avoid hours of rework during rigging. Follow the folder structure and separation guidelines for head, body, and extras, then move on to rigging tutorials.

Tutorial Checklist

1 0:21 Create art of your VTuber model with many individual layers and export as a PSD file.
2 1:34 Check your art program's layer cap (e.g., Procreate has a cap) — ensure it can handle many layers for complex models.
3 2:07 Organize layers into folders: a main body folder, subfolders for body parts (e.g., head, body), features, and left/right sides.
4 2:58 For the head, separate layers for face, eyes, front hair, ears, eyebrows, nose, and mouth. For simpler rig, keep some as whole layers; for 3D effect, separate further (e.g., front hair into middle/left/right).
5 4:19 Separate eye layers extensively: sclera, top lid, bottom lid, iris, pupil, lashes, highlights. For basic rig, at minimum separate the eye into at least the main shapes.
6 5:01 Separate mouth into: top lip, bottom lip, tongue, inner mouth, top teeth, bottom teeth.
7 5:29 Divide the body into left/right portions for arms, legs, torso, and boobs (if applicable). For more movement, separate limbs at joints.
8 5:58 Place non-bang hair in its own folder; include back of head and actual hair. Decide layer count based on hairstyle (solid piece vs. strands).
9 6:25 Add extra elements (expressions, accessories, animal ears/tails) in their own folders within the main folder.

[00:03] But have NO money to hire an artist

[00:07] Well, today is your lucky day

[00:11] how to become a 2D vTuber

[00:14] My God, OK, it's happening.

[00:16] Everybody, stay calm.

[00:19] So what do you need to start

[00:21] Well, first you need art of your vTuber model

[00:26] in a bunch of different little layers

[00:30] Then you will need to get an art

[00:35] which don't worry, I'll be covering in

[00:40] But for today, we're going to be focusing

[00:42] It is really important that you make sure

[00:47] at the early stage because if it's not. . . .

[00:57] OK, maybe not to that extreme,

[01:01] and you'll be wasting a lot of hours

[01:04] so let's go over

[01:07] Now, before I even show you

[01:12] that your art needs to be in a PSD file,

[01:17] This is because it is the only file type

[01:22] Yes, there are a lot of

[01:25] that can export your art in PSD!

[01:27] You don't have to just

[01:30] Just Google if your art program can export in PSD,

[01:34] one thing I would pay attention to is

[01:37] can handle. Because if you are thinking of

[01:42] procreate, then you have a layer cap,

[01:46] if you're planning on making

[01:49] OK, now that we got that out of the way.

[01:51] Let me show you my layers. Mm-Hmm.

[02:00] OK, I know this looks

[02:03] but trust me, it will all make sense

[02:07] If you happen to notice I have all of my

[02:10] different folder categories, then good job

[02:14] I have them in several folders

[02:15] to categorize everything better because

[02:20] it will be organized to help you sort

[02:23] and it honestly saves you so much time.

[02:26] Everyone has their own special way

[02:29] but I like to do it like this

[02:34] kind of like the whole main body

[02:37] Then a bunch of subfolders

[02:41] and then another category of folders

[02:46] Then lastly, I need any layers

[02:49] side of each corresponding part

[02:52] I want using different model examples

[02:56] you can make your avatar

[02:58] Let's start with the head first,

[03:00] since that is literally the most important

[03:04] in my opinion, since, well, it's

[03:09] The head can be divided

[03:13] the eyes, the front hair, the ears,

[03:18] So most of these don't have to be separate

[03:22] For example, the nose,

[03:25] they can all be on their own whole layer

[03:29] But if you want to separate each of these

[03:30] a little further

[03:33] then you can separate the face layer

[03:36] If your character has it

[03:40] the nose can be separate into the lineart,

[03:43] And lastly, the front hair

[03:47] The left and the right part separating it

[03:50] an almost 3D effect with your vTuber

[03:54] and don't worry! I'll show you how to do that

[03:55] in another video later :)

[03:56] the ears and the eyebrows folder,

[04:00] You literally just need to separate them

[04:04] and it should all be drawn on its own

[04:06] Hey, are you still with me, Bobas!?

[04:08] You better let me know by giving this

[04:11] if you haven't already!!!

[04:12] I do a lot of tutorials like this,

[04:16] content on my channel.

[04:17] Thanks so much. Now for the eyes.

[04:20] I want you to pay close attention.

[04:23] You need to just stop.

[04:24] OK, I'm sorry. You need a separate

[04:28] Even the simplest models

[04:30] have quite a few layers for the eyes.

[04:32] This is because I rigging is

[04:37] especially if you don't

[04:40] Here's how you should separate the

[04:43] If you want to get a little fancy and

[04:48] then you can separate the iris,

[04:53] And don't worry,

[04:55] Another Live2D eye rigging tutorial for you

[04:58] The mouth can be separated

[05:02] It really comes down

[05:03] to how much control you want over

[05:06] I personally would recommend

[05:10] lip layer, the tongue, the inner mouth

[05:14] in the bottom teeth if you have any.

[05:15] It's a little bit more simpler in terms of

[05:19] but the rigging part of it is actually just

[05:23] as complicated, and that's all the parts

[05:26] Now let's move on our body.

[05:29] The body can be divided

[05:33] This is a lot simpler

[05:37] any further than besides their

[05:41] But of course, if you want to have

[05:44] then you have to separate your limbs

[05:46] by their joints, and I recommend

[05:50] If your model has them.

[05:55] the rest of the hair that doesn't include

[05:59] You have pretty much the back of the head

[06:03] and then the actual hair. Now depending

[06:07] That's going to determine

[06:09] because you can either separate it

[06:13] or you can just kind of

[06:16] If you make it this far into the video,

[06:19] you're pretty much done

[06:22] You don't have to separate or add

[06:25] But if you were thinking of adding things

[06:31] ears, tails etc. Then of course

[06:36] and added to the main folder
