GPT Image 2 Character Sheet Prompts: Turnarounds, Expressions, and Consistency

May 4, 2026

キャラが毎回変わるのは “センス不足” ではなく invariants 不足です。ここでは gpt image 2 character sheet prompts を使って、turnaround / expression / pose を再現性ある形にします。

チーム運用では、1 つの gpt image 2 character sheet prompt を version 管理して baseline にするのが最短です。これは gpt image 2 character consistency prompts の実装でもあります。

- Create a 4-panel character turnaround sheet (front, 3/4, side, back)
[PASTE identity block here]
Layout: 2x2 grid, equal panels, labels readable
Invariants: same camera, same lighting, keep facial identity consistent
Output spec: 4:5, quantity 1

Expression sheet prompt

Goal:
- Create a 12-panel expression sheet for the same character
[PASTE identity block here]
Layout: 3x4 grid, head-and-shoulders, labels readable
Variables: expressions only
Output spec: 4:5, quantity 1
