提示词库 · 等距图标
十个实测提示词，用于黏土质感的等距图标和微缩场景——设备、建筑、小房间——外加那句让整套图标像一家人的风格句。每张卡片都是未经修改的输出。
一条等距图标提示词是两句话，各干各的活。第一句点名物体及其细节：「a small clay-render coffee machine with a chrome portafilter and a tiny cup on the tray」。第二句是风格句，在整套图标里从不改动：「isometric 3D icon, 45-degree view, soft matte clay materials, rounded edges, pastel palette, soft studio light with a gentle shadow, plain off-white background, centred with generous margin」。让一套图标成其为一套的一切，都住在第二句里。
把「isometric」和「45-degree view」明确说出来——不说的话，模型会漂到正面产品照或戏剧化的低角度，整套就不齐了。「Rounded edges」和「soft matte clay」正是当下应用与SaaS插画里主流的Blender风质感来源；换成「low-poly flat shading」或「glossy plastic with rim light」，同一个物体就落到了另一个视觉世界。下面这十个图标全是在BananaBanana上生成的首次未修改输出，多数用的是$0.03的Lite。
冻结风格句，只改物体那一段。听起来理所当然，却恰恰是大家做错的那一件事：每个图标都把整条提示词重写一遍，配色开始游移，一个回来是亮面另一个是哑光，整套始终对不上。复制粘贴的纪律，就是全部技巧。
另有两点有帮助。用具体颜色写明配色——「pastel palette of cream, sage, soft coral and pale blue」——而不是听天由命；并保持背景措辞完全一致，这样图标的裁切位置才一样。如果某个图标还是跑了风格，别从零重写：用同样的文本再生成一次，或者编辑最接近的那个好结果。另外，因为这些是位图，放进界面时要么先做一次抠底，要么就放在它们生成时那张同样的米白卡片上。
下面每张图片都是所在卡片提示词的未修输出——没有从几十次尝试里挑好的，也没有修图。模型徽标标明了它由什么生成、花了多少钱。
Isometric 3D icon of a compact espresso machine with a chrome portafilter, a small cup on the drip tray and a tiny steam wand. 45-degree isometric view, soft matte clay materials, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, object centred with generous margin.
Isometric 3D icon of an open laptop on a small desk with a mug, a stack of two books and a tiny potted plant. 45-degree isometric view, soft matte clay materials, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, blank screen with no text, centred with generous margin.
Isometric 3D icon of a small three-storey corner shop building with an awning, two street trees and a bench outside. 45-degree isometric view, soft matte clay materials, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, no signage or text, centred with generous margin.
Isometric 3D icon of a rounded delivery van with chunky wheels and two small parcels stacked beside the rear doors. 45-degree isometric view, soft matte clay materials, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, blank unbranded panels, centred with generous margin.
Isometric 3D icon of a small server rack with three units, tiny status lights and a loop of cable running to a floor socket. 45-degree isometric view, soft matte clay materials, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, centred with generous margin.
Isometric 3D miniature room: a tiny bedroom with two walls cut away, showing a bed with a folded blanket, a rug, a bedside lamp and a window with a plant on the sill. 45-degree isometric view, soft matte clay materials, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, centred with generous margin.
Isometric 3D icon of two payment cards fanned on top of each other with a small coin stack beside them and a rounded card terminal behind. 45-degree isometric view, soft matte clay materials, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, blank cards with no numbers or logos, centred with generous margin.
Isometric 3D icon of a chunky mirrorless camera mounted on a small tripod, with a spare lens standing beside it. 45-degree isometric view, soft matte clay materials, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, no branding, centred with generous margin.
Isometric 3D icon of a stubby rounded rocket on a small launch pad with a service gantry and two puffs of cloud at the base. 45-degree isometric view, soft matte clay materials, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, centred with generous margin.
Isometric 3D icon of a small glass greenhouse with a pitched roof, three shelves of seedlings visible inside, a watering can and a bag of soil by the door. 45-degree isometric view, soft matte clay materials, frosted translucent glass, rounded edges, pastel palette of cream, sage and soft coral, gentle studio light with a soft shadow beneath, plain off-white background, centred with generous margin.
物体那一段可以变，风格那一段永远不变。把同一句「isometric 3D icon, 45-degree view, soft matte clay, rounded edges, pastel palette…」尾巴复制进这套里的每条提示词——正是这种重复，让十次独立生成看起来像一个图标包。
不写的话，模型过几个图标就滑向正面或英雄角度，网格就对不齐了。这是提示词里最便宜的一致性保险。
屏幕、卡片和店面最爱招来编造的字母，而生成的文字几乎总是畸形的。「Blank screen with no text」「no signage」「unbranded panels」能让图标保持干净可用。
图标后续会被裁成圆形、方形和卡片。生成时在物体周围留出可见留白，意味着你之后可以裁切，而不必重新生成。
不能直接生成——模型输出的是不透明图像，所以这里每条提示词都指定了纯米白背景。事后去掉它在任何编辑器里都是一键的事，而且平背景上的黏土质感图标抠图很干净，因为边缘柔和却分离得很清楚。
不是。这些是1K的位图，用于网页界面、演示文稿、落地页和应用商店截图完全够用。如果你需要可缩放的矢量图标，就把生成的图当作设计参考去描摹——这里的价值在于几秒钟锁定视觉，而不是产出SVG。
$0.03的Lite处理大多数单物体图标绰绰有余，所以上面十个里有七个用的是它。遇到带室内、玻璃或多层叠加元素的场景再升到Nano Banana 2——温室和剖面卧室正是那点额外能力显出来的地方。
只替换材质那几个词。「Low-poly flat shading, hard edges, limited flat colours」或「glossy plastic with a bright rim light and reflective floor」能用同一份物体清单产出完全不同的套装。新的风格句同样要固定住，就像你对黏土那句做的一样。
可以——你在BananaBanana上生成的内容归你所有，包括随商业应用或网站一起发布的图标。只要像这里的提示词一样，不写进品牌名和logo即可。
