AI PNGTuber and VTuber Asset Generator for Avatars, Emotes, and Stream Graphics
Create matching avatar states, editable vector emotes, and stream graphics around one character reference.
Start generatingA PNGTuber asset generator creates matching 2D avatar states and supporting stream graphics. AI Art Create can generate the source art and editable vector assets, but microphone-driven switching still happens in streaming software such as Veadotube Mini or an OBS-compatible setup.
A PNGTuber kit usually begins with two matching avatar states: mouth closed and mouth open. Most creators add emotional variants, emotes, badges, and scene graphics next. AI Art Create combines reference-guided image generation with Recraft V4 vector output, giving new streamers a practical way to prototype a complete visual kit before commissioning final rigging or illustration.
How to build a PNGTuber kit that switches cleanly
Start with the silent state
The first useful asset is not a full VTuber model. It is one front-facing PNGTuber avatar with open eyes and a closed mouth. Keep the head near the center, leave breathing room around hair and accessories, and use a silhouette that remains readable over a game or chat window.
Approve the face, hair, costume, and palette before creating reactions. FLUX.2 accepts a source image, so the chosen silent state can guide the rest of the kit. This is also where you should simplify tiny jewelry, teeth, and fabric patterns that will flicker when two states alternate.
Make the speaking state a small edit
Reuse the silent avatar and request only an open mouth. Do not ask for a new pose, camera angle, and emotion in the same pass. Overlay the two images and toggle between them: the eyes, chin, shoulders, crop, and canvas position should stay still. If the whole head jumps when the microphone activates, the pair is not ready.
Veadotube Mini's documentation describes the simple setup as two images—closed mouth and open mouth. A four-image state adds closed-eye versions of both for automatic blinking. That is a more concrete starting point than generating a dozen emotions before the core pair works.
Treat emotes and badges as tiny graphics
A good avatar illustration can be a bad Twitch emote. At chat size, the face needs a larger expression, the outline needs more separation, and props need to disappear unless they carry the joke. Twitch auto-resize accepts one square PNG from 112×112 to 4096×4096 under 1 MB; manual mode uses 28×28, 56×56, and 112×112 files under 100 KB each, according to the official subscriber emote guide.
Subscriber badges are smaller still: Twitch requires transparent PNG files at 18×18, 36×36, and 72×72, each under 25 KB. Recraft V4 is useful for clean, editable SVG concepts and exact palette instructions, but it has no reference-image input in this catalog. Describe the approved character's colors and signature shape explicitly, then check the exported raster at 18 pixels.
Configure switching outside the generator
AI Art Create generates source images, vectors, and short clips; it does not rig Live2D, export VRM, or listen to your microphone. Assign the mouth states in Veadotube Mini or another reactive-avatar app, then capture that app in OBS.
For transparency, Veadotube's OBS setup guide recommends a transparent display and “Allow Transparency” on the OBS capture. If that fails, use a solid background and a Colour Key filter—but choose a key color that does not appear in the hair, eyes, or costume.
What you can generate
- Two-state PNGTuber
- The minimum viable set is an eyes-open, mouth-closed PNG and a matching mouth-open PNG. Keep the crop and head position identical so microphone switching looks like speech rather than a camera cut.
- Four-image blink set
- Add closed-eye versions of both mouth states. Keep eyelids as the only eye-area change; regenerated eyebrows or cheeks create a visible flash when Veadotube alternates the files.
- Reaction states
- Create happy, angry, surprised, sleepy, or embarrassed states after the neutral pair works. Give each state its own matched open- and closed-mouth files if you want it to remain reactive while selected.
- Twitch and Discord emotes
- Design square, high-contrast reactions and inspect them at 28×28 pixels. Twitch can auto-resize one larger PNG, but manual 28, 56, and 112-pixel files give you control over which details survive.
- Subscriber badges
- Use a compact symbol rather than a miniature portrait. Twitch subscriber badges need transparent PNGs at 18×18, 36×36, and 72×72, each under 25 KB; validate the smallest file first.
- Stream scene graphics
- Create Starting Soon, Be Right Back, and offline art around the same palette. Use 16:9 for the scene, preserve an open area for chat or schedule text, and keep the character away from crop-sensitive edges.
The failure modes to catch before you stream
The most obvious defect is positional jitter. Put the silent and speaking files on two layers at 50% opacity. If the shoulders, fringe, or pupils do not overlap, regenerate the speaking state from the reference and say that only the mouth may change.
Transparency needs a separate check. Raster models do not guarantee a transparent PNG. Background removal can leave a pale fringe around hair, while a chroma key can erase costume colors that resemble the key. Test the actual OBS scene, not just the image on a checkerboard.
Finally, do not confuse asset generation with rigging. A PNGTuber set switches complete images; a Live2D model needs separated layers and rigging, and a 3D VTuber needs a modeled and rigged VRM. Use this workflow to prototype the identity and produce stream graphics, then commission or build the appropriate rig if your format needs continuous head and body motion.
Recommended models
FLUX.2
Black Forest Labs · 6 credits per generation
Use the approved silent avatar as a reference and ask for mouth, blink, or expression edits one at a time.
Accepts a reference image. Ratios: 1:1, 16:9, 9:16, 4:3, 3:4.
Limit: Prompt following rewards specificity, vague briefs undersell what it can actually do.
Recraft V4
Recraft · 6 credits per generation
Use for flat SVG emote and badge concepts with an explicitly written palette. It cannot inspect the avatar reference in this catalog.
Text-to-image only in this catalog. Ratios: 1:1, 16:9, 9:16.
Limit: Built for icons, logos, and flat illustration, not photorealistic scenes.
Wan 2.2
Alibaba · 45 credits per generation
Use for an optional five-second reaction clip. It does not replace microphone-driven PNG switching or Live2D rigging.
Accepts a reference image. 5 clips. Ratios: 16:9, 9:16, 1:1.
Limit: Less cinematic camera control than Kling or Veo, better suited to simpler motion than tight choreography.
Frequently Asked Questions
Does AI Art Create rig a Live2D or VRM model?
No. The current product generates image, vector, and short video assets. Live2D rigging, VRM modeling, and microphone switching require separate software.
Can I generate transparent PNGTuber images?
Transparent raster export is not guaranteed across every model. Recraft V4 supports native vector output, while other results may need background removal before streaming.
What sizes should Twitch emotes use?
Twitch commonly displays emotes at 28 by 28, 56 by 56, and 112 by 112 pixels. Start from a clean, simple design and check legibility at the smallest size.
Can I animate a reaction image?
Yes. Upload an approved still to Wan, Kling, or another image-to-video model and describe one short reaction. The resulting clip can be edited into a loop.
