Rengoku Character Swap: An Incomplete Reference — AI Image Prompt Guide

This reference concerns a Rengoku character swap but lacks the key prompt. Treat it as an incomplete comparison rather than a reproducible tutorial.

English translation of the public case notes.

Incomplete comparison case involving Rengoku. The public material says the same prompt was tested with this character, but the available original prompt is only a model name. That is insufficient to reconstruct composition, style or camera design. A meaningful comparison needs the complete original prompt, character or reference description and earlier result. Describe the character and action first, then framing, lighting effects, background and style. A model name alone is not an executable visual brief. Avoid treating the model name as an image description or omitting reference provenance, character features and shot scope. Practical controls: • Specify hair colour, clothing, expression and pose rather than only the name. • Hold composition and lighting constant to isolate the character substitution. • For a public video case, include the intended opening frame or cover. This note does not reconstruct the missing prompt.

📐 Prompt 工程|炼狱案例缺了关键提示 这是一个图像案例案例。 这套写法稳在:这条素材提到用同一提示词测试 Rengoku,但公开的原始提示仅是模型名,无法复盘构图、风格或镜头设计。适合作为发布规范提醒:角色案例应附完整提示词、参考图和编辑目标。 Prompt 结构: 类型:对照测试 输入:完整原始提示词、角色名或参考图说明、需要对照的上一版结果;当前只看到模型名,信息不足。 目标:复现或比较同一提示词换成 Rengoku 后的角色画面表现。 关键词:Rengoku / 同提示词测试 / 角色替换 / 动漫风格 / 复盘不足 重点:应先写主体角色与动作,再写构图、光效、背景和风格;仅写模型名不会形成可复现的创作指令。 约束:避免把模型名称当作画面描述;避免缺少参考图来源、角色特征和镜头范围,导致结果不可对照。 💡 三个关键控制点 • 明确角色外观要素,如发色、服装、表情、姿态,而不是只写角色名。 • 保留同一构图与光照条件,才能判断“换角色”带来的差异。 • 若用于公开视频案例,应补充首帧目标或封面目标,方便他人复现。 #GPTImage2 #OpenAI #AI绘画 #角色同人 #动漫海报 #提示词复盘

完整提示词如下(来自该帖子作者 @Mayz1169 在后续回复中公开分享的内容):

Using the character reference image I upload, create a pixel-art battle animation. Deliver a transparent animated GIF and a 4×4 sprite sheet containing 16 sequential frames.

CHARACTER FIDELITY  
Identify the character’s hairstyle, outfit, colors, weapon, proportions, and distinctive features. Translate them into a recognizable chibi pixel-art sprite. Keep the character’s identity, scale, clothing, and equipment consistent across all frames.

BATTLE DESIGN  
Automatically design an attack that suits the character:  
If they carry a weapon, build the animation around it.  
If their abilities are clearly identifiable, use the appropriate effects, such as water, fire, or lightning.  
If their abilities are unclear, create a plausible physical attack based on their appearance. Do not invent unrelated powers.  

Proceed without asking preliminary questions. Create one coherent battle loop:  
Ready stance → Anticipation → Attack → Impact peak → Effects dissipate → Recovery.  

Distribute the sequence naturally across 16 frames. The final frame must transition smoothly into the first. Animate actual changes in pose and body mechanics; do not fake movement by merely translating or rotating a static character image.

PIXEL-ART STYLE  
Use crisp 16-bit game-style pixel art with readable silhouettes, sharp pixel edges, and a restrained palette. Maintain a consistent pixel scale for both the character and effects. Avoid blur, photorealistic rendering, and style drift.

SPRITE SHEET REQUIREMENTS  
Exactly 4 columns × 4 rows, totaling 16 frames.  
Frames play left to right, then top to bottom.  
All cells must have identical dimensions.  
Use a fixed camera, consistent character scale, a stable ground baseline, and consistent animation registration.  
Each cell contains exactly one character.  
Keep the entire body, weapon, and effects inside its cell.  
Leave sufficient transparent padding on every side. Nothing may cross cell boundaries or be cropped.  
No text, frame numbers, grid lines, watermarks, or background scenery.

TRANSPARENCY AND ANIMATION  
Generate a genuinely transparent RGBA PNG. Do not draw a checkerboard pattern to imitate transparency.  

Slice the sheet into frames and assemble a transparent, infinitely looping GIF. Adjust frame durations to emphasize anticipation and fast strikes. Aim for a total loop duration of approximately 1.5–2 seconds.  

Preserve full alpha transparency in the PNG files. Use a transparent palette index and correct frame disposal in the GIF to prevent trails from previous frames.

DELIVERABLES AND QUALITY CHECK  
Create the actual files, not just prompts or instructions:  
A transparent 4×4 PNG sprite sheet.  
A playable transparent battle GIF.  
A ZIP containing all 16 individual transparent PNG frames.  

Before delivery, verify that there are exactly 16 frames, transparency is genuine, the character remains consistent, no neighboring frames bleed into the crops, the action plays in the correct order, and the loop has no obvious positional jumps. Fix any issues before presenting the GIF preview and download links.
