Visual signature: what defines an Idol VTuber
Aim for a soft, kawaii concert vibe. Flat pastel shading keeps tones clean and graphic; reserve gradients for subtle bloom and eye highlights. Prioritize neat lineart, glossy anime eyes, and tidy accessories (headset mic, ribbons, frills). Backgrounds read as a shallow 2.5D stage: LED panels, volumetric haze, rim lights, confetti bokeh. Palette trends toward candy pastels (peach, mint, lavender) with high-value backgrounds to maintain character focus. Outfit motifs: sailor-inspired collars, pleated skirts, bows, star charms.
Prompt blueprints
Use clear subject-first phrasing, list core style tokens early, then lighting and scene context. Keep camera terms near the end. Add a concise negative list to reduce stage artifacts and hand errors. For consistency across batches, pin the seed and reuse the same base prompt scaffold; vary only pose, camera, and color accents.
- Solo portrait: idol vtuber, flat pastel shading, soft clean lineart, glossy anime eyes, headset mic, frilly stage costume, ribbons and bows, kawaii, 2.5d stage lights, pastel color palette, soft bloom, confetti bokeh, upper body portrait, looking at viewer, sharp focus
- Full-body stage pose: idol vtuber on concert stage, dynamic dance pose, flat pastel shading, neat lineart, 2.5d lighting, rim light and led floor reflections, volumetric haze, audience glowsticks, full body, wide shot, low angle
- Group energy: idol vtuber duo, synchronized dance, matching pastel outfits, flat pastel shading, 2.5d spotlights, colorful led wall, shallow depth of field, medium wide shot
- Stream thumbnail: idol vtuber, cute victory pose, clean background with subtle gradient, flat pastel shading, soft rim light, space for title text, chest-up shot, centered composition
- Negative (append): extra limbs, malformed hands, deformed microphone, broken anatomy, text watermark, heavy grain, color banding, cluttered background
Lighting setup: 2.5D stage lights
Simulate a concert look without full 3D complexity. Use a soft front key for skin clarity, a saturated rim from stage edges, and floor LED reflections to suggest depth. Prompt accents like neon rim lighting, volumetric haze, light shafts, and confetti bokeh. Keep exposure moderate; too-bright gels flatten pastels. Color pairings: cyan-magenta, pink-lavender, or mint-lilac. To avoid banding in pastel skies and LED gradients, reduce contrast, add subtle film grain, or prompt for smooth shading and clean gradients.
Motion basics: clean dance loops
For short, loopable dance clips, drive movement with a pose or motion controller and ensure the first and last frames align. Favor 1–2 beat gestures (2–4 seconds) so loops feel natural. Use a pose reference sequence or skeleton to keep hands away from the mic when switching poses. Stabilize face shape with consistent seeds or an identity LoRA. Export at a steady frame rate (24–30 fps) and trim to the beat for seamless repetition.
- Loop pipeline: pick a 2–4 s dance ref → generate on-beat keyframes → interpolate/smooth → color match → trim to loop
- Keep the camera stable for loops; move lights and confetti instead for energy
- Match first and last pose; crossfade 2–6 frames if needed
- Use haze and bokeh to hide micro pops between frames
Camera and composition
The 2.5D look benefits from simple parallax and readable silhouettes. For portraits, keep headroom and center line symmetrical; for dance shots, use a low angle and medium-wide focal length to elongate legs and show stage floor. Add shallow depth-of-field to separate the subject from LED walls. Include foreground glowsticks or confetti for depth cues, but keep them soft so they don’t obscure hands or mic.
- Aspect ratios: 9:16 shorts/reels; 16:9 streams; 1:1 thumbnails
- Go-to lenses: 35–50 mm look for full body; 70–85 mm look for portraits
- Keep hands clear of face and mic to reduce generation artifacts
Model, controls, and settings
Use an anime-focused diffusion model with a clean VAE for smooth pastels. Add a lightweight outfit or identity LoRA when you need repeatability across scenes. Pose control keeps limbs stable during dance gestures; apply it lightly during portraits to preserve expressive hands. Typical settings: steps 20–30, CFG 4–7 for smooth shading, lower strength for ControlNet during stylization passes. If colors clip under stage lights, lower saturation in the prompt and increase exposure headroom; consider a subtle filmic tone curve in post.
Quality control and troubleshooting
Common issues include tangled fingers on microphones, stray ribbons intersecting hair, banding in LED gradients, and over-bloomed highlights that erase lineart. Pre-empt with negative prompts for extra limbs and banding, add clean lineart and tidy accessories, and reduce haze strength when detail matters. For thumbnails, simplify the background to maintain text legibility. For videos, lock the face identity across frames with consistent seeds or face stabilization.
- Hands/mic collisions: stronger pose control on wrists/fingers; simplify prop angle
- Pastel banding: add smooth shading, gentle grain; reduce contrast in gels
- Over-bloom: lower glow/bloom tokens; raise lineart emphasis
- Identity drift: reuse seed; apply light identity LoRA; stabilize keyframes
