The practical choice is between two different production pipelines. For a 2D avatar, create a layered illustration, prepare its parts for movement, rig it in Live2D Cubism, and run the finished model in Live2D-compatible software such as VTube Studio. For a 3D avatar, customize a character in VRoid Studio, export it as a VRM file, and run that file in VRM-compatible software such as VSeeFace.
Neither format is universally better. Your artwork, desired style, editing skills, tracking hardware, software compatibility, licensing needs, and budget all matter. The most important decision is to choose the runtime before you export: VTube Studio loads Live2D Cubism models and does not support VRM, while VSeeFace supports VRM and VSFAvatar and does not support Live2D.

What you are actually making
A VTuber avatar is not just a picture or a character file. It is a character asset plus a runtime that displays it and converts your facial or body movement into animation. The asset, the rig or expression data, the tracker, and the application must agree on a format.

- 3D pipeline: a three-dimensional character is assembled and textured, exported in the VRM format, and animated by a VRM-compatible application.
- Runtime: software such as VTube Studio or VSeeFace displays the avatar and receives webcam or phone-tracking input. VTube Studio describes itself as an application for loading a model made elsewhere, not as a character-creation editor (VTube Studio on Steam).
Think of the file format as a contract. A beautifully finished model is unusable in a program that cannot read that format, so compatibility belongs at the beginning of the project rather than at the end.

2D or 3D: the decision at a glance
| Decision point | 2D Live2D route | 3D VRM route |
|---|---|---|
| Starting asset | A prepared, layered illustration with parts separated for movement. | A character assembled and edited in VRoid Studio, including presets, sliders, clothing, hair, and textures. |
| Core creation work | Illustration processing, layer organization, mesh deformation, parameters, expressions, body and facial movement, and motion in Live2D Cubism. | Character customization, texture drawing, VRM export, and any expression or blendshape setup required by the destination application. |
| Typical compatible example | VTube Studio, which supports Live2D Cubism models. | VSeeFace, which supports VRM and VSFAvatar. |
| Customization approach | Transform and animate artwork that has already been drawn. | Choose presets and adjust features, then edit textures and other character elements in a 3D editor. |
| Tracking choices | VTube Studio documents both smartphone and webcam face tracking. | VSeeFace documents webcam tracking and gives guidance on camera resolution and lighting. |
| Up-front asset question | Do you already have layered art, or do you need an illustrator and a Live2D rigger? | Are the available presets and texture tools sufficient, or will you need custom modeling or conversion work? |
| Rights question | Confirm that you may use, modify, rig, and publish the illustration and the resulting model. | Check the terms for your own VRoid data and for every Pixiv or third-party asset included in the character. |
This table describes the documented workflows, not a promise that one format is always less expensive, easier, or better tracked. Finished commission prices and effort vary with the scope of the character and the rights you require.
How to make a 2D Live2D avatar
1. Plan the illustration around movement
Start by deciding which parts must move independently. A face that needs to blink requires separate eyelid or eye layers; a mouth that changes shape needs the mouth components separated from the surrounding face; hair, accessories, shoulders, arms, and clothing may need their own layers if they will sway or turn.
Draw the character in an organized source file rather than flattening it into one image. Hidden areas behind the face, hair, and clothing often need to be painted because those areas can become visible when the model turns. The exact layer plan depends on the design and the range of motion you want, but the principle is constant: Live2D can only deform or reveal artwork that exists in the source material.
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Live2D’s official tutorial sequence begins with illustration processing and preparing the illustration to move, then progresses through expressions, body movement, facial movement, and motion (Live2D Cubism tutorials). Use that sequence as a practical checklist before opening the rigging editor.
2. Prepare and import the artwork
- Finish the character design and name layers clearly, using a consistent structure for eyes, brows, mouth, hair, face, body, clothing, and accessories.
- Separate every element that should move independently. Keep alternate expressions and mouth shapes as distinct, editable parts where appropriate.
- Paint enough hidden coverage for turning, leaning, blinking, and other intended movements.
- Export or save the layered artwork in a format that Live2D Cubism can import, then verify that transparency and layer order are intact.
- Open the artwork in Cubism and inspect the imported layers before building any deformation. Fix missing, merged, or incorrectly ordered parts at this stage.
Do not confuse this preparation with tracking. At this point you are constructing the model’s visual source; no camera is required.
3. Rig movement in Live2D Cubism
In Cubism, the illustration becomes a deformable model. You assign meshes and parameters so the software can interpolate between poses. Begin with small, testable movements: eye blinking and simple vowel mouth shapes are used as introductory exercises in Live2D’s tutorials. Then extend the setup to head angle, eye direction, eyebrows, mouth width and open amount, body angle, hair, clothing, and accessory motion as your art supports it.
Build and test one parameter at a time. A useful order is:

- Create expressions that combine the underlying parameters instead of replacing the neutral face.
Preview extreme parameter combinations. A model can look correct in a neutral pose yet expose unpainted areas, intersect layers, or distort the mouth when the head turns and the eyes close together. Correct those failures in the mesh, parameter ranges, or source art before export.
4. Export for a Live2D runtime
When the model works in Cubism, export the runtime files required by the application you selected. VTube Studio is a common example for Live2D Cubism models, but the important rule is format support, not the name of one application. VTube Studio’s manual states that it supports Live2D Cubism and does not support VRoid or VRM (VTube Studio manual: Introduction & Requirements).
Load the exported model in the runtime and check texture paths, expressions, physics, and parameter names. If a model appears blank or lacks movement, first verify that you exported the correct runtime package and that the application supports that package.
5. Add phone or webcam tracking
VTube Studio supports smartphone tracking as well as webcam tracking; its webcam mode does not require the smartphone app (VTube Studio manual: Introduction & Requirements). A phone can therefore be a useful way to avoid buying a camera, while a webcam may be more convenient for a permanent desk setup.
Recommended Free Tools
For VTube Studio webcam tracking, the manual recommends 1280×720 or higher for good eye and blink tracking and describes 15–30 frames per second as sufficient. These are setup recommendations from the manual, not a guarantee of identical results for every camera or room.
- Connect the phone or webcam and grant the tracking application camera permission.
- Select the correct device in the runtime and confirm that a live preview shows your face.
- Position the camera near eye level, keep your face inside the frame, and calibrate with a neutral expression.
- Test blinking, looking up and down, turning your head, opening your mouth, and making the expressions you intend to use on stream.
- Adjust smoothing or sensitivity only after confirming that the model’s parameters are correctly rigged. Tracking controls cannot repair a missing or incorrectly named parameter.
6. Confirm art and usage rights
If someone else draws or rigs the model, put the intended uses in writing before work begins. Ask whether you may stream, monetize videos, edit the files, create alternate outfits, transfer the model to another runtime, and credit the artist in a specified way. Live2D’s tutorial site references a marketplace for rights to use and process illustrations and Live2D data (Live2D Cubism tutorials), but that reference does not establish a standard commission price or a particular artist’s terms.
Do not assume that paying for artwork automatically grants every right. Keep the source illustration, the Cubism project, exported runtime files, and the written license together so you can prove what you are allowed to do.

How to make a 3D VRM avatar in VRoid Studio
1. Start with a base and customize the character
VRoid Studio provides presets and editing controls for facial features, hair, clothing, and other character elements. Its official page also describes drawing and editing textures, so you can move beyond preset colors when the design needs a custom pattern or detail (VRoid Studio).
- Install VRoid Studio and create a new character from a suitable base.
- Adjust facial proportions and features with the available controls.
- Choose or edit hair, clothing, and accessories to match the design.
- Open the texture editor for custom colors, markings, logos, and patterns.
- Rotate the model and inspect it from multiple angles. A texture or hairstyle that looks correct from the front may not work from the side or back.
- Save incremental versions so you can return to a working character if a later edit causes a problem.
A pressure-sensitive pen tablet or stylus is optional, not a minimum requirement. VRoid Studio says its texture editing supports pressure-sensitive pen tablets, and its iPad version supports Apple Pencil (VRoid Studio). Use one if it improves your drawing workflow, but do not treat it as mandatory equipment.
2. Export a VRM file
When the character is ready, export it as a VRM model. VRM is the file format the documented 3D runtime route expects. Before exporting, remove or replace assets whose licenses do not allow your intended use.
VRoid states that creators can define terms for data they create, including whether commercial use is allowed and whether credit is required. For Pixiv or third-party data, it directs users to follow that data’s own terms and licensing conditions (VRoid Studio). Read those terms for every imported texture, item, hairstyle, or accessory rather than applying the terms of your own character to someone else’s asset.
3. Open the model in VRM-compatible software
VSeeFace is an example of a runtime that supports VRM and VSFAvatar. Its documentation explicitly says it does not support Live2D, so a Cubism model cannot be substituted for a VRM file there (VSeeFace).

- Check that the model loads at the correct scale and that hair, clothing, and accessories are attached correctly.
- Select your webcam and confirm that the application receives a camera image.
- Calibrate with a neutral pose, then test head turns, eye movement, blinking, mouth movement, and expressions.
- Save the runtime’s avatar or tracking configuration if the application provides that option.
4. Check expressions and blendshapes
VSeeFace’s documentation explains that behavior depends on the VRM expressions and blendshape setup. A model can therefore load successfully yet respond poorly if its expression definitions are incomplete or mapped unexpectedly. Check the model’s expression settings in the runtime and adjust the model or conversion settings when a blink, mouth shape, or other expression does not trigger as intended.
This is the main difference between exporting a file and finishing an avatar. Export verifies that a VRM file exists; expression testing verifies that the receiving application can use the data in the way you expect.

Software compatibility is the non-negotiable checkpoint
| Avatar or file | Use it with | Do not expect it to work in |
|---|---|---|
| Live2D Cubism model | VTube Studio and other applications that explicitly support Live2D Cubism. | VSeeFace, which documents VRM and VSFAvatar support rather than Live2D support. |
| VRM exported from VRoid Studio | VSeeFace and other applications that explicitly support VRM. | VTube Studio, whose manual says VRM and VRoid models are not supported. |
| Unfinished source artwork | An art editor and then Live2D Cubism after layer preparation. | A tracking runtime by itself; a runtime cannot rig a flattened illustration for you. |
| VRoid project file | VRoid Studio for further editing and a VRM export step. | A runtime that accepts only exported VRM files. |
Before commissioning art or spending time on customization, write down the target runtime, accepted file format, tracking method, and required expression controls. This prevents the common failure of completing a model that your chosen application cannot load.
Camera, phone, lighting, and room setup
Phone tracking versus webcam tracking
Phone tracking is a valid starting route for a 2D setup because VTube Studio documents smartphone tracking in addition to webcam tracking. It can reduce the equipment you need at your desk, although it adds a device connection and charging consideration. Webcam tracking keeps the camera attached to the computer and is also documented for VTube Studio and VSeeFace.
Webcam resolution and frame rate
For VTube Studio webcam tracking, use 1280×720 or higher if you want the manual’s recommended eye and blink tracking quality; 15–30 FPS is described as sufficient. VSeeFace describes 720p to 1080p as its webcam-resolution sweet spot and warns that higher resolution does not automatically improve tracking (VSeeFace).
These figures do not make an expensive camera necessary. An ordinary 720p USB webcam can meet the documented resolution range, and phone tracking may let you avoid buying one altogether. Choose a camera only after checking which runtime you will use and whether your computer can maintain a stable frame rate.
Lighting and positioning
Place the camera near eye level and illuminate your face from the front or slightly to the side. VSeeFace notes that insufficient light can reduce camera frame rate, so improve the room lighting before assuming that a higher-resolution camera will solve tracking problems. Keep strong backlighting from turning your face into a silhouette, and avoid covering the eyes or mouth during calibration.
Costs, free software, and licensing
| Item | What the official information establishes | What it does not establish |
|---|---|---|
| VRoid Studio | The official page says, “You can use any version of VRoid Studio for free.” (VRoid Studio) | It does not make every imported asset free to use or grant commercial rights to third-party data. |
| VTube Studio desktop | The Steam listing describes the desktop application as free and lists optional paid DLC, including optional watermark-removal DLC. Check the live listing for current pricing (VTube Studio on Steam). | It does not price the artwork, rigging, or commission work used to create your model. |
| Live2D artwork and rigging | Live2D’s tutorial site identifies a marketplace for rights to use and process 2D assets (Live2D Cubism tutorials). | No authoritative, comparable total commission price is established for a finished 2D avatar. |
| VRoid assets | Creators can set terms for data they create; Pixiv and third-party assets follow their own stated conditions (VRoid Studio). | Free software does not mean unrestricted commercial use of every model component. |
There is no authoritative like-for-like total price for a finished 2D commission versus a finished 3D commission in these sources. Request quotes based on a written scope: number of expressions, outfit changes, physics, commercial use, revisions, source-file delivery, and the runtime you need. Do not use the software’s free price as a proxy for the total cost of a commissioned avatar.

A first-session checklist for each route
2D checklist
- Choose a Live2D-compatible runtime before commissioning or drawing.
- Write a movement brief covering head angles, blinking, mouth shapes, expressions, body movement, hair, clothing, and accessories.
- Create and organize the layered illustration, including hidden coverage.
- Import it into Live2D Cubism and test the meshes and parameter ranges.
- Build facial movement first, then add body and secondary motion.
- Export the runtime files and load them in VTube Studio or another application that supports Live2D Cubism.
- Connect a phone or webcam, calibrate, and test every expression you plan to use.
- Archive the source art, Cubism project, exports, and usage agreement.
3D checklist
- Choose a VRM-compatible runtime before you finalize the character.
- Create the character in VRoid Studio using presets, feature controls, and texture editing.
- Check every imported item for commercial-use, modification, credit, and redistribution conditions.
- Export a VRM file and keep a versioned copy of the VRoid project.
- Load the VRM in VSeeFace or another VRM-compatible runtime.
- Verify expression and blendshape behavior, not just whether the model opens.
- Configure webcam tracking, calibrate, and test lighting and frame rate.
- Save the final VRM and the license information for included assets.
Troubleshooting by symptom
The application says the model is unsupported
Check the file format first. A VRM export belongs in a VRM-compatible application such as VSeeFace; a Live2D Cubism model belongs in VTube Studio or another Live2D-compatible runtime. Do not try to solve a format mismatch by changing camera settings.

The model loads but does not move
Confirm that the camera permission is granted, the correct device is selected, and the tracking preview shows your face. Then inspect the model’s parameters or expressions. A tracker cannot animate a 2D model whose blink or mouth parameter was never rigged, and VSeeFace notes that VRM behavior depends on the model’s expression and blendshape setup.
Eyes or mouth look wrong at extreme poses
For Live2D, return to Cubism and test the parameter range, mesh, layer order, and hidden artwork. For VRM, inspect the expression or blendshape mapping and the source model’s corresponding definitions. Test one movement at a time before combining expressions.
Tracking is jittery or misses blinks
Improve front lighting, keep the camera near eye level, and confirm that the image is sharp. In VTube Studio, the documented webcam target is 1280×720 or higher with 15–30 FPS sufficient; in VSeeFace, 720p to 1080p is described as the sweet spot. A higher resolution alone is not a guaranteed fix, especially in a dim room.
Free tools Windows power users keep installed
One-click scans. No signup required.
The avatar includes an asset you cannot legally use
Stop publication of that version, identify the asset’s license, and replace it or obtain permission. Your own character terms do not override the conditions attached to Pixiv or other third-party data. Keep a record of permissions and required credit before you stream.
How to choose without relying on format stereotypes
Choose the 2D route when the visual identity depends on a specific illustration style and you are prepared to organize layered art and learn deformation-based rigging. Choose the 3D route when you want to assemble a character from editable presets and textures, or when your target application is built around VRM. Those are workflow-based decisions, not claims that every 2D model costs less or every 3D model is easier.
Use this sequence to make the decision:
- Name the destination application. Write down whether it accepts Live2D Cubism, VRM, VSFAvatar, or another format.
- Inventory your starting assets. A layered illustration points toward Live2D; a character you can build in VRoid Studio points toward VRM.
- Define the movement you actually need. List head angles, blinking, mouth shapes, expressions, body movement, outfit changes, and secondary motion.
- Choose tracking hardware. Start with a phone if that meets your 2D setup, or an ordinary webcam in the documented 720p–1080p range for the relevant runtime.
- Price the complete scope. Include art, rigging, custom textures, revisions, commercial rights, and source-file delivery rather than only the software license.
- Verify rights before export. Record permissions for your own work and for every third-party component.
The best beginner workflow is the one whose asset format, runtime, tracking method, and rights all line up before you start. A carefully prepared 2D illustration can become a responsive Live2D model, while a well-licensed VRoid character can become a flexible VRM avatar; each succeeds when its pipeline is kept intact.
Frequently Asked Questions
Can I use a VRoid model in VTube Studio?
No. VTube Studio supports Live2D Cubism models, and its manual states that it does not support VRoid or VRM. Export a VRoid character as VRM and use a VRM-compatible runtime such as VSeeFace.
Do I need to buy a webcam to start?
Not necessarily. VTube Studio documents smartphone tracking as well as webcam tracking. If you use a webcam, VTube Studio recommends 1280×720 or higher for good eye and blink tracking, while VSeeFace describes 720p to 1080p as its sweet spot.
Is a free avatar software license the same as free commercial rights?
No. VRoid Studio is free to use, and VTube Studio’s desktop listing describes a free application with optional paid DLC, but artwork and third-party assets have their own usage terms. Check commercial use, credit, modification, and redistribution conditions for every component.
