怎么填变量：[流行文化科幻主题] 可以换成"复古露营主题""赛博朋克猫咪主题"；[醒目的 3D 飞碟] 换成你的主体，如"戴耳机的宇航员头盔""喷火的小恐龙"，后面两句的材质和光效也跟着改；标题文字建议用 1～3 个英文单词或 2～4 个汉字，字越少印出来越好看。

示例图左半边是图案本身：黑底上一架银色飞碟，底部青色灯光，向下打出粉紫色光束，光束里站着一个小小的人影，下方是金属质感的大字"FIRST CONTACT"；右半边是原作者展示的上身效果——图案印在一件黑色 T 恤胸前。

常见问题：

• 背景不是透明而是黑色 / 棋盘格：让它输出"纯色背景（与衣服同色）"，再用抠图工具处理。
• 图案细节太多、印出来糊：删掉星星和轨道环，只留主体和标题。
• 出现多余小字：保留"只有一处文字"那一条并放到最前面。

适合：T 恤 / 卫衣 / 帆布袋印花、社团文化衫、周边设计初稿。售卖前请确认图案不含他人受保护的形象或商标。

A {argument name="theme" default="premium pop nerd culture t-shirt graphic"} isolated on full transparency with no background, centered in a square canvas, featuring a {argument name="hero object" default="bold 3D flying saucer"} as the hero object, designed with a sleek metallic chrome body, glowing cyan underside lights, and a luminous neon magenta beam projecting downward in a clean dramatic cone; beneath the UFO, a tiny silhouetted human figure looks upward in awe, kept simple and minimal for readability, while small floating stars and thin orbital ring fragments add just enough cosmic energy without clutter; the only text should be the {argument name="text title" default="large title “FIRST CONTACT”"} in a single bold futuristic display font, oversized, highly legible, and placed prominently below the UFO; no tiny text, no subtitles, no extra words, no scenery, no frame, no halo, no background elements, crisp sharp vector-clean edges, optimized for direct-to-garment printing and merch sales, high-resolution 4000x4000 px, professional 3D render quality, isolated on complete transparency, 1:1 square ratio.
