Stage 1: Define Character Anchors (CRITICAL)
[!IMPORTANT] Mustuse in all image generationscompletely identicalcharacter anchor descriptions, otherwise it will cause inconsistency between group and solo images!

Clothing Anchor System (CRITICAL)
[!IMPORTANT] Mustcreate an anchor description for each outfit, and both group and solo images reference the same anchor to ensure the clothing is completely consistent!

Stage 3: Generate Group Portrait
Group Portrait Scene Design Principles (CRITICAL)
[!IMPORTANT] The group portrait needs a setting, butmust not steal the spotlight! The setting serves the theme, and the characters are always the visual focus.
Composition Priority (front to back)
- Foreground Characters - Absolute main subject, highest clarity and saturation
- Ground/Platform - Supports the characters, provides a sense of space
- Midground Props - 2-3 small props echoing the theme, restrained and not cluttered
- Background Atmosphere - Blurred treatment, enhances the atmosphere
Background Handling Techniques
| Technique | Prompt Keywords | Effect |
|---|---|---|
| Depth of field blur | soft bokeh background, blurred background elements |
Highlight foreground characters |
| Color downgrade | desaturated background, muted background tones |
Avoid the background stealing attention |
| Simplify elements | minimal background props, subtle scene elements |
Avoid clutter |
| Atmospheric glow | soft ambient glow, dreamy atmosphere |
Add a sense of layering |
Group Portrait Prompt Structure
## Collection Group Shot Prompt
### 1. Scene Setting (布景但不喧宾夺主)
Blind box collection display, professional product photography,
[主题场景描述，如: cozy Halloween pumpkin patch setting],
soft gradient background with subtle [主题元素] silhouettes in bokeh,
foreground figures in sharp focus, background softly blurred,
desaturated background tones to emphasize characters
### 2. Platform/Ground (承载角色的平台)
[平台描述，如: wooden crate platform with scattered autumn leaves],
platform color complementing but not competing with figures
### 3. Arrangement
[数量] designer toys arranged in a group, varied heights and positions,
some standing, some sitting, natural grouping with breathing room
### 4. Characters (从左到右，每个必须完整描述，引用服装锚点)
- Left 1: [完整角色描述 + 发色 + 服装锚点内容]
- Left 2: [完整角色描述 + 发色 + 服装锚点内容]
- Center: [完整角色描述 + 发色 + 服装锚点内容]
- Right 2: [完整角色描述 + 发色 + 服装锚点内容]
- Right 1: [完整角色描述 + 发色 + 服装锚点内容]
### 5. Background Props (克制！2-3个即可)
- [道具1，如: carved pumpkin with soft glow, slightly out of focus]
- [道具2，如: small pile of candy corn, blurred in background]
### 6. Lighting (突出角色)
Product photography lighting, soft box lighting,
rim light for character separation from background,
[氛围打光，如: warm orange ambient glow from below]
### 7. Technical
High quality render, 4K, detailed [材质] texture,
depth of field with f/2.8 equivalent bokeh
Stage 4: Create Position Mapping Table (CRITICAL)
After generating the group portrait,immediatelycreate a position mapping table,must reference clothing anchors：
| Group Portrait Position | Style Name | Fur Color/Hair Color (Exact) | Clothing Anchor Reference | Pose | Corresponding Single Character Image |
|---|---|---|---|---|---|
| Left 1 | Pumpkin Cloak Style | Cream Brown #D2B48C | → Outfit-01 | Standing pose holding a pumpkin lantern | 01-pumpkin-cape.png |
| Left 2 | Little Devil Style | Caramel Brown #8B4513 | → Outfit-02 | Playful one-foot standing | 02-little-devil.png |
| Center | Ghost Cloak Style | Cream Brown #D2B48C | → Outfit-03 | Floating and drifting | 03-ghost-cloak.png |
| Right 2 | Wizard Style | Dark Chocolate #3D2314 | → Outfit-04 | Sitting pose flipping through a magic book | 04-wizard.png |
| Right 1 | Hidden Style - Skeleton | Moonlight White #F5F5F5 | → Outfit-05 | Lying pose playing dead | 05-hidden-skeleton.png |
Stage 5: Generate Single Character Images One by One
[!IMPORTANT] The group portrait must be used as a visual reference! Text descriptions alone cannot guarantee consistency; Gemini needs to directly see the character images in the group portrait.
Single Character Image Generation Method (CRITICAL)
When generating each single character image,must simultaneously provide：
- the group portrait image - as a visual reference
- Position indication - clearly specify which character in the group portrait it is
- Text Prompt - supplement scene and technical details
Single Character Image Prompt Structure
## Individual Figure Prompt
### 0. Visual Reference (CRITICAL - 必须包含！)
[附上群像图片 00-collection-group.png]
请参考上面的群像图片，为我生成其中 **[位置描述]** 的角色的单人特写图。
位置描述示例：
- "从左数第1个角色"
- "最右边的角色"
- "正中间的角色"
- "从右数第2个角色（穿紫色巫师袍的那个）"
这个角色在群像中的特征：
- 服装：[简要描述，如：紫色巫师袍，尖顶帽]
- 姿势：[群像中的姿势，如：盘腿坐着]
- 位置：[精确位置，如：右边第二个]
请保持这个角色的所有视觉特征（毛色、服装颜色、配件、比例）与群像完全一致！

professional product photography, chibi proportions
### 2. Character Anchor (从角色锚点完整复制！)
[完整的LOCKED特征描述]
### 3. Fur/Hair Color (必须显式声明！从映射表复制！)

Platform: [承载平台描述]
### 7. Lighting
[打光描述，见打光库]
rim light for figure separation
### 8. Technical

detailed [材质] texture, soft shadows,
depth of field with background blur
Operation Steps When Calling Gemini
- Upload the group portrait image - use
00-collection-group.pngas the input image - Clearly indicate the position at the beginning of the Prompt - "Please refer to this group portrait and generate for methe 2nd character from the right's single character image"
- Emphasize consistency requirements - "Must maintain an appearance fully consistent with that character in the group portrait"
- Provide a complete scene description - The background, lighting, etc. can differ, but the character itself must be consistent
Scene and Lighting Library
| Atmosphere | Scene Elements | Background Description | Lighting |
|---|---|---|---|
| Cozy Warmth | Fireplace, wooden floor, Christmas stockings, blanket | warm living room | warm orange glow, fireplace lighting |
| Dreamy Starry Sky | Stars, moon, falling stardust, window | night sky through window | soft blue-purple gradient, moonlight |
| Sweet Candy | Gingerbread house, candy decorations, lollipops | candy land background | pink warm lighting, sweet ambiance |
| Festive Joy | Christmas tree, gift boxes, string lights, gold decorations | festive holiday scene | colorful bokeh lights, warm festive |
| Fresh Snow Scene | Snowflakes falling, ice crystals, snowy ground, white environment | snowy winter scene | cool blue-white lighting, soft diffused |

| Autumn Forest | Fallen leaves, mushrooms, tree stump, pinecones | autumn forest floor | golden hour warm light, dappled shadows |
Stage 6: Consistency Check
Required Check Items
| Check Item | How to Check | Common Issues |
|---|---|---|
| Hair Color Consistency | Compare the hair color of the same character in the group portrait and the single-character image | Group portrait blonde hair → single image brown hair |
| Eye Consistency | Check eye shape, size, and highlight position | Eyes become smaller / highlights disappear |
| Proportion Consistency | Check the head-to-body ratio | In the single image the head becomes smaller / the body becomes longer |
| Clothing Match | Compare clothing color and pattern | Pattern disappears / color shifts |
| Expression Match | Check whether the expression matches the design | Expression does not match the setting |
When inconsistency is found
- Identify the specific difference: hair color / eyes / proportions / other
- Check the single-image Prompt: Was the hair color declaration omitted?
- Modify the Prompt：
- Place the hair color description earlier
- Use a more emphatic tone:
Hair Color: MUST BE Golden blonde #F0C05A - Add negative prompts:
NOT brown hair, NOT dark hair
- Regenerate
Common Errors and Solutions
| Problem | Cause | Solution |
|---|---|---|
| Inconsistent hair color between group portrait and single image | Hair color was omitted from the Prompt | Each imagemustexplicitly declare hair color + Hex color code |
| All poses are standing poses | The pose library was not used | Refer to the pose library and choose a different pose for each version |
| The background is too simple | Only "white background" was written | Add scene elements + atmosphere + lighting description |
| Character proportions are inconsistent | The head-to-body ratio was not locked | Fix the proportions in the character anchor and repeat them every time |
| Eye style changes | Eye features were not described in detail | Lock eye size, shape, and highlight description |
