AI雨景绘画教程：从江南烟雨到暴风雨的雨天氛围Prompt全攻略

画过很多雨天场景——最常翻车的是"雨滴在积水上打出的涟漪"。AI要么画成一个完美的同心圆涟漪（像物理学教材里的示意图），要么干脆不画涟漪只画了一层模糊的水面贴图。真实的涟漪是重叠的——一个涟漪还没散开另一个已经砸下来，水面是一张永远在变化的动态图案。

雨天Prompt最被低估的要素——不是雨本身，是"雨对一切东西的影响"。地面变深色了、树叶被打弯了、人的头发贴着头皮了、眼镜片上全是水珠——这些"雨的后果"比"雨的形态"更能传达雨天的沉浸感。

四种雨的Prompt

江南烟雨。"gentle misty rain over a Jiangnan water town, the rain is so fine it's almost fog, white walls and grey tile roofs glistening with moisture, a stone bridge arching over a canal, an oil-paper umbrella held by a distant figure, the entire scene is soft and dreamlike, not sharp rainfall but suspended water particles in the air"。烟雨=细到看不见雨丝-只能看到雾气和反光的水面。

暴雨。"heavy torrential downpour, thick diagonal rain streaks visible against dark storm clouds, the rain is bouncing off surfaces creating a layer of mist near the ground, flash reflections on flooded streets, the wind is bending trees, the storm has weight and force"。暴雨=雨丝不是装饰性元素-它是画面的主角。

车窗雨。"view through a rain-streaked car window, the outside world is a blur of city lights distorted by water rivulets on the glass, water droplets on the window catching bokeh from traffic lights, the interior of the car is dark and quiet, intimate and melancholic atmosphere"。车窗雨是最有"故事感"的雨景类型——隔着玻璃看世界=你和世界之间隔了一层。

雨后的城市街头。"a city street just after rain has stopped, the wet pavement reflecting neon signs in puddles, the air is clean and fresh, scattered people with umbrellas folded walking carefully around puddles, the lingering dampness in the air"。雨后="雨已经不下了但一切都还记得雨"——湿漉漉的地面和倒影。

让雨“真实”的四个物理描述

雨丝方向和粗细。“diagonal thin rain streaks at 30 degrees, not wall of water, individual droplets visible with long exposure motion blur”。涟漪叠加。“overlapping ripples on puddles, multiple concentric circles interfering with each other, water surface constantly changing”。湿润反射。“wet pavement acts as a soft mirror reflecting neon lights and vertical shapes”。雾气与湿度。“low mist rising from wet ground, subtle atmospheric moisture, visibility reduced with distance”。这四条一起加，AI 的雨立刻从贴纸变成天气。

常见问题

AI画的雨丝为什么老像挂着水帘/白色贴纸？

因为默认按“雨”的图形符号画。改法：写“thin diagonal streaks at consistent angle, long exposure photograph aesthetic, motion blur streaks not white lines, subtle transparent rain not opaque”。加否定“no cartoon rain, no wall of white lines”。

怎么画“雨已经停了”那种氛围？

用“just after rainfall”作为核心词组：“a city street just after rain has stopped, wet pavement reflecting neon, air is clean, no rain currently falling, only puddles and mist remain”。AI 会把主体放在“湿润后果”而不是“雨”。

雨中的人物怎么画得像“真的在淋雨”？

写“wet hair clinging to the forehead, water droplets on eyelashes, transparent raindrops on jacket surface, subtle steam from the body in cold air, no dry-looking clothes”。头发湿贴 + 睫毛水珠 + 衣物透明感，是关键三件套。

做雨天氛围商用（城市漫步 vlog、影视封面）有版权风险吗？

雨景通用无版权。避坑：招牌不用具体品牌名，人物不用真人明星。参考AI绘画黑夜可以把雨和夜景组合成电影感场景。

最好的雨景不是“雨下得多猛”，是“雨停了之后地面上的倒影告诉你刚才有一场雨”。把雨的后果写清，你的画面就有了空气湿度。
