# 3D Animation Short Generator

Use this Skill when the user wants a complete story-first animated short workflow, from one-line idea to final edited video. The workflow must place every major artifact on the canvas in production order and pause at creative gates with user choice cards before expensive or high-impact steps.

Core rule: **story first, ask screen size and total duration with choice cards immediately after user intake, ordered canvas artifacts, every required confirmation via choice card, fixed order after character/scene cards: six-column standardized shot table with per-second directives + audio cues + spatial anchor chain → shot-table self-check gate → one single text storyboards document with one section per shot (multi-panel pencil image only when user explicitly opts into visualization mode; any shot flagged for heavy iteration is extracted to a standalone text storyboard node) → video-model choice card (H3 default, Seedance 2.0 fallback) + resolution choice card → single-shot clips rendered by the chosen video model → full-film assembly with BGM; final video must remove all storyboard artifacts**.

## Global Visual Style Lock

Unless the user explicitly requests another visual style, all character cards, scene cards, shot tables, text storyboards, optional pencil storyboards, single-shot video clips (regardless of which video model is selected), assembled videos, and final composites must use this visual style:

- Rendering style: Pixar-inspired 3D cartoon rendering, C4D + Octane renderer look, high-end animated feature quality.
- Character design: exaggerated geometric simplification balanced with excellent material detail. Avoid 100% realistic human anatomy; use high-level shape language, large readable silhouettes, and Q-version proportions when appropriate.
- Proportion language: friendly stylized proportions, often 2.5–3 head-tall for cute or childlike characters, with big heads, compact bodies, clear silhouettes, and high recognizability.
- Hair / fur: combine strong sculpted clumps and clean block shapes with fine edge flyaway hairs or fuzzy rim details, so hair/fur feels designed but tactile under light.
- Skin / material: warm subsurface scattering skin quality, soft translucent reddish light through ears, cheeks, nose, and fingertips; avoid hard plastic skin.
- Acting style: exaggerated, lively Disney/Pixar-style character animation performance with squash and stretch, strong brows, eye corners, pupils, lips, and cheek shape changes.
- Motion style: high-energy poses, clear line of action, forward lean, strong anticipation, fast but readable timing, elastic body mechanics, and vivid micro-expressions.
- Emotional range: balance cuteness and explosive expressiveness; intense emotions may use dramatic facial deformation while preserving character appeal.

Negative style constraints: no photorealistic live-action, no flat 2D anime, no plastic toy skin, no stiff mannequin posing, no realistic anatomical stiffness, no lifeless facial expressions.

## STEP 0: Intake and Canvas Plan

Capture:

- One-line idea or rough premise
- Desired output: blueprint only, assets only, standardized shot table with per-second directives, single text storyboards document (default) + extracted single-shot text storyboard nodes for heavy-iteration shots + multi-panel pencil storyboards (opt-in), single-shot video clips (with video model chosen in Step 7), assembled main video, or final BGM-composited film
- Approximate length, if the user already stated it
- Screen size / aspect ratio, if the user already stated it
- Visual tone: default warm stylized 3D animation
- Dialogue requirement: whether the film has dialogue, voiceover, or no speech
- Dialogue language only if the user explicitly states it; do not default to English dialogue

Immediately after capturing the user's input, before Project Brief or any other next step, show choice cards to confirm production format:

Screen size / aspect ratio card:

- 16:9 landscape (recommended for cinematic short)
- 9:16 vertical short
- 1:1 square
- 4:5 social portrait
- Custom size / aspect ratio

Total duration card:

- 30–60 seconds (recommended)
- 15–30 seconds
- 60–90 seconds
- 90–180 seconds
- Custom duration

Only proceed after the user chooses both screen size/aspect ratio and total duration, or explicitly supplies custom values. Store the approved screen size/aspect ratio and duration in the Project Brief and reuse them in shot timing, transition continuity, the standardized shot table with per-second directives, single-shot storyboards (text by default, pencil image when user opts in), single-shot video clips, assembly, BGM matching, and final composite settings.

Create or later update canvas artifacts in this order:

1. Project Brief text node
2. Story Outline text node
3. Labeled Character Card image nodes
4. Environment-only Scene Card image nodes
5. Standardized Shot Information Table node with six columns; each row must include per-second directives inside `Shot Description`
6. **Single text storyboards document** — one canvas text node named `<title> text storyboards` containing one section per shot (mirrors the half-narrated-drama storyboard structure). When the user flags a shot for heavy iteration, that section is extracted to a standalone text node and a `(extracted)` marker is left in the document. Pencil image storyboards, if opted in, are separate image nodes.
7. Single-Shot Video Clip nodes (rendered by the video model selected in Step 7 — H3 default, Seedance 2.0 fallback)
8. Assembled Main Video node
9. Matched BGM audio node and Final BGM-Composited Video node

Do not dump long production content only in chat. Put durable outputs on canvas as text, image, video, or audio nodes.

## STEP 1: Project Brief

Produce a concise project brief and write it to a canvas text node named with the project title or `项目简报`.

Include:

- Working title
- One-line What-if
- Emotional premise
- Target audience feeling
- Main deliverables planned
- Approved screen size / aspect ratio
- Approved total duration
- Dialogue mode and language: only use a specific language when the user explicitly requested it; otherwise write `language not specified` and keep dialogue minimal or ask later when needed
- Initial risks
- Dialogue intent when present

Then show a user choice card:

- Continue with this direction (recommended)
- Regenerate premise options
- Revise emotional premise
- Refine dialogue direction

Only proceed after the user chooses or explicitly says to continue.

## STEP 2: Story Outline and Gates

Create a story outline and write it to a canvas text node named `故事大纲` or `story-outline`.

Include:

- Protagonist Want / Need / flaw
- Core world rule
- 8-beat causal story spine
- Emotional anchor and payoff
- Dialogue beats if the user requested dialogue
- Red-line checks

Gate checks:

- Protagonist is active
- Crisis is intensified by protagonist flaw
- Coincidence never solves the problem
- Ending reuses an earlier emotional anchor
- Antagonistic pressure is not a flat villain
- Dialogue reveals relationship change instead of explaining the theme

Then show a user choice card:

- Approve story and continue (recommended)
- Revise beats
