## Prompt

- Model: Nano Banana Pro

```text
First, analyze **the source image (flower, clothing, pattern, etc.)**.

Instruction to ChatGPT:

"Convert this image into a JSON prompt, including size, color, shape, and details."

Instruction: "Metaprompt Goal: Create a prompt for NanoBananaPro that draws the specified texture onto a UV deployment map. Perform a process similar to Substance Painter, generating the texture by referencing image 2 against the UV map. Based on this JSON, create a prompt to change the color by referencing an additional image. Aim to create a prompt template in JSON format that generates a skirt texture on a UV map. Clearly instruct NanobananaPro to create the color based on this image. Generate a single prompt JSON according to a predefined JSON schema: ..."
```

Original prompt (ja):

```text
まず、**元にしたい画像（花・服・模様など）**を分析させる。

ChatGPTへの指示：

「この画像を、サイズ・色・形・ディティールまで含めてJSONプロンプト化して」

指示：「メタプロンプトGoal：NanoBananaPro用にUV展開図の上から指定のテクスチャーを描かせるプロンプトを作成してください。Substance paintみたいな処理を行い、画像２をUV展開図に照らし合わせて生成させてください。このJSONをベースに追加画像を参考に色を変えるためのプロンプトを作成してください。JSON形式でUV展開図にスカートのテクスチャを生成するプロンプトテンプレートの作成を目指す。NanobananaProにこの画像を参考にして色を作成してって言うのを明確にして。あらかじめ定義されたJSONスキーマに従って、1つのプロンプトJSONを生成してください：…」
