How to Rig a VTuber Model
What rigging actually is, how to do it in Live2D, and how to skip it completely.
Rigging is the process of turning a flat drawing into a puppet. You add a skeleton, deformers and physics to your avatar's art so that individual parts, the eyes, mouth, head and hair, can move independently and be driven by face tracking. It is what makes a rigged 2D VTuber look alive.
How to rig a 2D model in Live2D
- 1Prepare your art as separated layers in a PSD (eyes, mouth, hair, body, all on their own layers).
- 2Import the PSD into Live2D Cubism.
- 3Create deformers and parameters so parts can rotate, open and close.
- 4Add physics so hair and accessories sway naturally.
- 5Export the model and load it into a tracking app like VTube Studio.
- 6Calibrate webcam or iPhone face tracking to your expressions.
Rigging is powerful, but it has a genuine learning curve. Many creators spend days or weeks getting it right, and a professional rigging commission commonly runs from one hundred to well over a thousand dollars.
Rigging sounds like a lot, right?
StreamSprite gives you a reactive avatar with zero rigging. Frames in, character out. $20 once, macOS.
The no-rigging alternative
If rigging is more than you want to take on, you can skip it entirely. PNG-based reactive avatars need no rig at all. There are no PSD layers to separate, no deformers to build, and no face tracking to calibrate. You supply a few frames and the software animates them to your voice. That is exactly how StreamSprite works, and it is why a beginner can be on stream in about five minutes.
Which is right for you?
Choose rigging if you want fluid, expressive, camera-driven movement and are happy to invest the time or money. Choose the PNG route if you want to be live now, keep things simple, and spend your energy on content rather than software. You can always rig a model later once your channel is established.
Skip the rigging. Be live in 5 minutes.

Frequently asked questions
Do I have to rig my VTuber avatar?+
No. Rigging is only needed for models driven by face tracking. PNG-based avatars react to your voice with no rigging at all.
How long does it take to rig a model?+
For beginners, days to weeks in Live2D. Commissioning a rigger is faster but costs money. A PNG avatar takes minutes and skips rigging entirely.
Can I be a VTuber without rigging?+
Yes. Many popular VTubers use PNG avatars that need no rigging. StreamSprite is built for exactly this.
