产品视觉 GPT Image 2 提示词：3D Packaging to 2D Net Unfolding
A technical prompt for industrial design that unfolds 3D packaging into a flattened 2D net with precise texture mapping and die-lines.
📝 提示词
Flatten 3D packaging into 2D net. Expand all panels and tabs. Orthographic projection, no distortion. Map textures precisely. Add contrasting die-lines. {argument name="background" default="Pure white background"}.
🎯 适合场景
适合快速搭建产品图、包装展示和品牌海报：主体、材质、背景与商业修图方向已经有框架，换掉变量就能开跑。
💡 改写建议
- 先替换变量里的品类、人物、城市、品牌色，不急着改整段结构。 把主体、构图和风格分开写，后续微调会更稳。
