AI Character Sheet Generator

Overview

A structured workflow for creating comprehensive character reference sheets that maintain visual consistency across AI-generated images and video clips. The character sheet locks every visual attribute — face, build, clothing, accessories — so that any future generation of this character matches the original.

Without a locked character sheet, AI tools generate a different-looking person in every frame, destroying continuity instantly.

When to Use

• Before generating any multi-shot AI video sequence
• When a character must appear consistently across multiple images
• When building a cast for an AI short film or ad
• When establishing a visual identity for a recurring AI character

Character Sheet Structure

Every character sheet must define three sections: Identity, Visual Attributes, and Reference Angles.

Section 1 — Identity

Name:        [Character name or identifier]
Role:        [Brief narrative role — protagonist, antagonist, bystander]
Age Range:   [Apparent age bracket]
Archetype:   [Visual archetype — corporate exec, street artist, soldier, etc.]

Section 2 — Visual Attributes

Lock every attribute explicitly. Ambiguity causes drift between generations.

Category	Attributes to Lock
Face	Face shape, skin tone, skin texture, eye color, eye shape, eyebrow thickness, nose shape, lip shape, facial hair
Hair	Color, length, style, texture (straight/curly/wavy), parting direction
Build	Height impression (tall/average/short), body type, shoulder width, posture
Clothing	Exact outfit description — fabric, color, fit, layers, accessories
Distinctive	Scars, tattoos, piercings, glasses, birthmarks, jewelry, watch
Hands	Ring details, nail style, gloves, visible veins/calluses if relevant

Section 3 — Reference Angles

Generate four canonical views using identical prompt attributes:

1. FRONT VIEW    — Face-on, neutral expression, arms relaxed at sides
2. SIDE VIEW     — Full profile (left or right), same pose
3. BACK VIEW     — Full rear view showing hair and clothing from behind
4. 3/4 VIEW      — Three-quarter angle, slight turn, most natural pose

All four must share: same lighting, same background (neutral gray or white), same clothing, same lens (85mm portrait).

Image Prompt Template

Use this template for each of the four reference angles:

[ANGLE] view of [IDENTITY SUMMARY].
[FACE ATTRIBUTES]. [HAIR ATTRIBUTES]. [BUILD DESCRIPTION].
Wearing [EXACT CLOTHING DESCRIPTION]. [DISTINCTIVE FEATURES].
Neutral gray studio background, soft diffused lighting,
85mm portrait lens, photorealistic, high detail, no motion blur.

Example — Front View

Front view of a 30-year-old East Asian man with a sharp jawline.
Warm olive skin with natural texture, dark brown almond-shaped eyes,
thin eyebrows, straight nose, clean-shaven. Black straight hair,
medium length, side-parted left. Athletic build, broad shoulders,
upright posture.
Wearing a fitted dark navy crew-neck sweater over a white t-shirt,
black slim-fit jeans, silver wristwatch on left wrist.
Small scar above right eyebrow.
Neutral gray studio background, soft diffused lighting,
85mm portrait lens, photorealistic, high detail, no motion blur.

Repeat for SIDE, BACK, and 3/4 views — changing only the angle line.

Output Format

When generating a character sheet, always return:

## Character Identity
[Name, role, age range, archetype]

## Locked Visual Attributes
[Full attribute table — face, hair, build, clothing, distinctive]

## Reference Angle Prompts
### Front View
[Complete image generation prompt]

### Side View
[Complete image generation prompt]

### Back View
[Complete image generation prompt]

### Three-Quarter View
[Complete image generation prompt]

Consistency Rules

1. Never improvise attributes — every generation must reference the locked sheet
2. Same lighting across all angles — soft diffused, neutral background
3. Same lens across all angles — 85mm portrait for consistency
4. Same clothing in every reference — outfit changes get a separate sheet variant
5. Copy attributes verbatim — when using the character in scene prompts, paste the locked attributes directly rather than paraphrasing

Common Mistakes

Mistake	Fix
Vague face description ("attractive man")	Lock every facial feature explicitly
Different clothing between angles	Copy exact clothing string across all four prompts
Fancy backgrounds in reference shots	Use neutral gray studio — backgrounds add visual noise
Missing distinctive features	Always include scars, tattoos, accessories — they anchor identity
Paraphrasing attributes in scene prompts	Copy-paste the locked attribute strings verbatim
Forgetting hand details	Rings, watches, gloves are continuity anchors — lock them

Integration with Other Skills

This skill feeds directly into ai-cinematic-video-director and ai-storyboard-to-video:

• Generate the character sheet FIRST
• Reference it in every start frame prompt and animation prompt
• Store as a reusable asset for the entire production
