Character Transparent Slices Prompt V1

Status

• Document status: used for first generation batch.
• Execution status: five slice candidates generated; review pending.
• Project: 在路上.
• Asset step: character transparent slices after accepted v2 main character anchor board.
• Review file: visual-system/characters/character-transparent-slices-review-v1.md.

Purpose

Create five transparent character cutout references for later MV shot prompting and possible compositing reference.

The slices are not final MV frames. They are execution assets that should preserve the accepted character identity while removing scene background influence.

Required slice set:

ID	Output candidate	Purpose
front	front full body	Locks body proportion, coat front, face / hair / beard direction.
side	side full body	Locks side silhouette, coat fall, backpack volume, profile.
back	back full body	Locks back-view recognition without face.
walk-side	walking side full body	Tests the upright walking posture required for road shots.
walk-back	walking back full body	Tests the most important later wide-shot silhouette.

Skill Workflow Record

Mode check command:

node C:\Users\wangq\.agents\skills\gpt-image-2\scripts\check-mode.js --json

Mode check result:

{
  "mode": "B-or-C",
  "recommendation": "host-or-advisor",
  "garden_mode_enabled": false,
  "has_api_key": false,
  "base_url": "https://api.openai.com/v1",
  "model": "gpt-image-2",
  "env_flag_value": "(unset)"
}

Interpretation:

• Use gpt-image-2 as the prompt-engineering workflow.
• Garden local generation is not enabled.
• This Codex environment has a host image-generation path, so later execution should be treated as Mode B if the user approves generation.
• No Garden scripts should be called for this step.

Skill files actually read:

• C:\Users\wangq\.agents\skills\gpt-image-2\SKILL.md
• C:\Users\wangq\.agents\skills\gpt-image-2\references\prompt-writing.md
• C:\Users\wangq\.agents\skills\gpt-image-2\references\portraits-and-characters\character-sheet.md
• C:\Users\wangq\.agents\skills\gpt-image-2\references\portraits-and-characters\pose-reference-sheet.md

Template adaptation:

• character-sheet.md provides the front / side / back view logic.
• pose-reference-sheet.md provides the same-character / pose-variation control logic.
• This project adapts both into five independent transparent cutout prompts, not a full character board.

Source Files Actually Used

Primary project sources:

• visual-system/characters/character-identity-lock.md
• visual-system/characters/character-anchor-review-v2.md
• visual-system/characters/character-anchor-prompt-v2.md

Visual references:

• visual-system/characters/character-anchor-v2-codex-posture-test.png: accepted main character anchor board.
• visual-system/characters/character-anchor-v1-codex-test.png: preferred original character-image direction.
• visual-system/characters/character-chatgpt.png: positive upright walking posture / board-quality reference.

Identity reference:

C:\Users\wangq\Pictures\照片\photo.jpg

Role:

• identity reference only;
• not an edit target;
• not a passport-photo style target;
• use only to preserve the lived-person basis and face direction when the execution tool supports image references.

Asset Format

Preferred output:

• five separate PNG images;
• transparent alpha background;
• one full-body character per image;
• no scene, no floor, no horizon, no labels, no board layout;
• full body must be fully inside the canvas, including head, coat hem, backpack, hands, boots, and any stride extension;
• consistent character scale across all five images.

Preferred canvas:

• individual vertical cutout canvas, about 2:3 or 3:4;
• if the host tool only supports a horizontal frame, center the character and keep enough empty transparent margin for cropping.

Transparency fallback:

• If true alpha transparency is unavailable, use a completely flat, clean, uniform near-white or very light neutral matte background with no texture and no shadow; mark the result as non-transparent fallback in the review.

Character Lock For All Slices

Every slice must depict the same person:

• 50-year-old male traveler;
• about 180cm tall;
• black rectangular glasses;
• dark, somewhat longer, slightly messy hair;
• visible gray / white streaks allowed;
• longer, denser beard / stubble, fuller than light stubble but still realistic and controlled;
• weathered middle-aged face;
• quiet, serious, tired expression with dignity;
• solid adult body, capable of continuing forward;
• dark gray / dark khaki / coal-black long traveler's coat;
• dark restrained inner layer;
• old dark pants;
• old practical medium-volume backpack, worn / dusty but not broken;
• old durable walking boots, road-worn and able to carry mud.

Character temperament:

• weathered by life and systems;
• warm but tired;
• lonely but steady;
• silent and not defeated;
• tired but dignified;
• road-worn, not ragged.

Critical Posture Rule

For all standing and walking slices:

The traveler may look tired, but he must not walk or stand with a bent waist, hunched back, rounded collapsed shoulders, bowed defeated head, or physically broken body.

Walking slices must show:

• upright chest;
• straighter spine;
• natural head and neck alignment;
• relaxed shoulders that do not collapse forward;
• steady forward movement;
• grounded but dignified gait.

Shared Negative Constraints

Strictly avoid:

• hunched walking posture;
• bent waist;
• rounded shoulders collapsing forward;
• bowed defeated head;
• collapsed, frail, or physically broken body;
• homeless stereotype;
• drunk stereotype;
• pity image or spiritual defeat;
• fashion model styling;
• polished travel blogger image;
• luxury outdoor gear;
• heroic poster stance;
• arms-open inspirational pose;
• celebrity portrait look;
• glossy game concept art;
• anime / cartoon styling;
• fantasy armor or costume;
• cyberpunk / neon / sci-fi / futuristic clothing;
• passport-photo style;
• front-facing glamour portrait;
• scenery background;
• city background;
• muddy road background;
• campfire background;
• dramatic studio shadow;
• text labels, captions, logos, UI, frames, borders, or annotation lines;
• multiple different men instead of the same traveler.

Base Prompt Block

Use this base block for all five slice prompts:

Create one realistic full-body transparent PNG character cutout for the music-video project "在路上".

Use the accepted character anchor board `character-anchor-v2-codex-posture-test.png` as the primary visual identity reference. Preserve the same 50-year-old male road traveler: about 180cm tall, black rectangular glasses, longer messy dark hair with possible gray/white streaks, longer and denser realistic beard/stubble, weathered middle-aged face, quiet tired dignity, solid adult body, dark gray / dark khaki / coal-black long road-worn traveler's coat, dark restrained inner layer, old dark pants, old practical medium-volume backpack, and old durable walking boots.

Use the source photo only as an identity reference if image-reference input is supported. Do not copy its red background, passport-photo pose, suit, lighting, or portrait framing.

The image is an isolated execution asset, not a final MV frame and not a character board. One full-body character only. Transparent alpha background. No scenery, no floor texture, no horizon, no text, no labels, no frame, no UI, no props other than the backpack and clothing system. Keep the whole body fully inside the canvas with clean transparent margins.

Style: realistic cinematic pre-production character cutout, low-saturation documentary road-film feeling, practical and restrained, not anime, not cartoon, not glossy game concept art, not fashion editorial.

The traveler may look tired, but he must not look collapsed, frail, homeless-coded, drunk-coded, heroic, or defeated.

Slice Prompt 1: Front Full Body

Output candidate:

visual-system/characters/character-slice-front-v1.png

Prompt:

[BASE PROMPT BLOCK]

Pose requirement: front full-body standing view. The traveler faces the camera naturally, feet grounded, shoulders relaxed, coat front visible, backpack straps or side edges visible if natural, hands neutral and unobtrusive. The body should feel tall, solid, and capable of walking, not heroic and not posed for a fashion portrait.

Purpose: lock age impression, body proportion, coat front, glasses, longer hair, fuller beard, and tired but dignified face direction.

Slice Prompt 2: Side Full Body

Output candidate:

visual-system/characters/character-slice-side-v1.png

Prompt:

[BASE PROMPT BLOCK]

Pose requirement: clean side full-body standing view, profile direction, full head-to-boots silhouette visible. Show the coat fall, backpack thickness and placement, profile of glasses, hair outline, beard profile, and boot shape. The torso must not collapse forward. Keep the spine naturally upright and the head aligned.

Purpose: lock side silhouette and backpack volume for later landscape-led side-view shots.

Slice Prompt 3: Back Full Body

Output candidate:

visual-system/characters/character-slice-back-v1.png

Prompt:

[BASE PROMPT BLOCK]

Pose requirement: back full-body standing view. The traveler faces away from the camera. Show stable back-view recognition: longer messy hair outline, old medium backpack centered on the back, long dark coat from shoulders to lower body, old pants, and road-worn boots. Shoulders are relaxed but not folded forward.

Purpose: lock the no-face identity used in distant MV shots.

Slice Prompt 4: Walking Side Full Body

Output candidate:

visual-system/characters/character-slice-walk-side-v1.png

Prompt:

[BASE PROMPT BLOCK]

Pose requirement: side full-body walking view, one step forward, natural road-walking gait. The traveler walks with upright chest, straighter spine, natural head and neck alignment, and relaxed shoulders that do not collapse forward. The coat moves slightly with the step, backpack sits naturally, boots show grounded forward motion.

Critical rule: do not bend the waist, do not hunch the back, do not bow the head, do not make him look physically broken or defeated. The walk should feel tired but dignified, steady, and capable of continuing.

Purpose: lock the main side-walking silhouette for road shots.

Slice Prompt 5: Walking Back Full Body

Output candidate:

visual-system/characters/character-slice-walk-back-v1.png

Prompt:

[BASE PROMPT BLOCK]

Pose requirement: back full-body walking view, the traveler moving away from the camera. Show a steady upright back, natural backpack placement, long coat movement, grounded boot stride, and the same longer hair outline. The body should read as continuing forward, not slumping away.

Critical rule: shoulders must not fold forward, spine must not hunch, head must not droop in defeat. The back view should feel lonely and tired but still dignified.

Purpose: lock the most important no-face walking silhouette for later wide shots.

Review Checklist

After generation, create a review file and check:

1. Do all five slices depict the same traveler?
2. Does the face / hair / beard / glasses system stay close to the accepted v2 anchor?
3. Do coat, backpack, pants, and boots remain stable across all slices?
4. Are the walking side and walking back slices upright enough?
5. Are head, coat hem, hands, backpack, and boots fully inside the canvas?
6. Is the background truly transparent, or only a fallback matte?
7. Does the side view preserve backpack volume without torso collapse?
8. Does the back view work without face details?
9. Do the assets avoid fashion, hero, homeless, drunk, and defeated-body drift?
10. Are the cutouts useful for later s01, s10, s46, s47, and s51 prompt work?

Next Gated Action

Only after user approval:

1. generate the five slice candidates;
2. save them under visual-system/characters/;
3. create character-transparent-slices-review-v1.md;
4. do not proceed to the common style anchor board until the slice review is accepted or intentionally skipped.
