Tsubaki 提示詞怎麼寫？用講的就能畫多角色場景

多角色場景畫不出來，大部分人第一反應是模型不行。實際上通常是提示詞沒把「誰、在哪裡、正在做什麼」講清楚。角色會糊在一起，是因為你只給了角色的身分，沒給它們各自的長相。

Tsubaki 讀的是句子的意思，不是逐字比對關鍵字。所以問題就變成：句子要怎麼寫。這篇用實際的失敗與修正過程，把 Tsubaki 提示詞的寫法走一遍。

📝 本篇談的是第一代 Tsubaki。後來推出的旗艦是 Tsubaki.2，這裡教的句子型提示詞寫法在新版上一樣通用。實際使用心得可以看 Tsubaki.2 使用心得。

寫 Tsubaki 提示詞之前：這個模型強在哪

它的設計目標不只是單張出圖好看，而是讓多張圖之間的設定與調性維持一致。

角色不會換人

以下三件事不會跑掉：

服裝與配件
換表情之後還是同一張臉
換場景之後還是同一個人

畫過漫畫就知道這有多要緊。同一張臉要撐過幾百格，而這正是多數模型最撐不住的地方。其他維持一致的做法，看 PixAI 角色一致性：三種入門方法。

複雜指令跟得完

條件一多也不會散掉。以下四個面向可以分別看。

人物跟背景不會各走各的

不是把人物貼在背景上，而是人在那個空間裡真的在做什麼。

構圖不會千篇一律

能跳出 AI 圖常見的那種正面半身構圖。想再深入研究構圖，看 AI 插畫構圖完全指南。

光影會對

光的擴散、角落積的暗部、陰影邊緣的柔度，彼此是搭得起來的。想主動設計光線，看電影級打光與景深。

有現實世界的常識

文化脈絡、時代背景、物理上說得通的狀況，它多少懂。這已經超出單純比對圖樣的層次。

步驟 0：先把提示詞助手打開

正式開始之前先講 提示詞助手。它在背後默默幫你把提示詞整理成模型讀得順的樣子。

它不挑輸入方式。只打 tag 可以、寫短句可以、兩種混著也可以，直接打中文也可以。

例如從這串 tag 開始：

1girl, black hair, short hair, school uniform, smiling

經過助手之後會變成這樣：

只寫短句的情況

tag 跟句子混著寫的情況

直接打中文的情況

櫻花樹下穿著和服的女性

差別看得出來吧。轉換後的版本多了姿勢、布料質感、整個場景的空氣感，出來的圖自然也比較完整。

生成完之後去生成任務那一區看，可以直接對照助手把你的輸入改成了什麼。這是練提示詞手感最快的方式。

💡 想關掉助手自己寫的話，英文敘述抓 30 到 150 個字效果最好。

自動完成、圖片轉提示詞這些其他輸入輔助，整理在 PixAI 提示詞工具 3 種比較。

Tsubaki 提示詞步驟 1 到 5：把一個場景疊出來

想像你在跟朋友描述一個畫面：「一個穿白色洋裝的女孩走過向日葵花田，午後的金色陽光把一切照得又暖又懷舊，像水彩畫活過來一樣。」

以前的做法是把這段拆成 1girl, full_body, walking_motion, sunflower_field, sunlight, golden_hour, watercolor_effect，而且就算拆完，那個「感覺」通常也不見了。Tsubaki 直接讀得懂，包括她是走在花叢之間、而不是站在花叢前面這件事。

下面的範例寫成英文，但你要用中文寫也行，助手會轉。重點是順序。

先放主角和正在做的事：“A blushing schoolgirl nervously adjusts her glasses with one hand while clutching a love letter in the other.” 這是整個場景的地基。
加上外型描述：“her long lavender hair fluttering slightly in the spring breeze.” 長相和動態一起交代。
定場地和光線：“Cherry blossom petals dance around her as she stands frozen outside the classroom door.” 季節一寫進去，打光和空氣感就跟著來。
補上她跟環境的關係：“mustering the courage to go inside.” 解釋了她為什麼站在教室門口，也暗示了下一個動作。
情緒不必另外寫。blushing、nervously、mustering the courage 這些字本身就帶著。

合起來就是這樣：

A blushing schoolgirl nervously adjusts her glasses with one hand while clutching a love letter in the other, her long lavender hair fluttering slightly in the spring breeze. Cherry blossom petals dance around her as she stands outside the classroom door, mustering the courage to go inside.

Tsubaki 提示詞步驟 6：兩個人以上怎麼寫

回到開頭那件事。以老爺車旁兩個青少年的場景為例，把「誰在哪裡做什麼」補齊。

先釘位置：“A red-haired girl sits on the hood… a black-haired boy stands beside the car.” 這是地基。
把兩個人寫成看得出差別：女生不是「制服」，而是 “black serafuku with sailor collar, pleated miniskirt, knee-high black socks”；男生不是「外套和褲子」，而是 “brown jacket over black shirt, black pants, glasses, grey scarf loosely draped”。這些細節就是指紋。
加小動作：不是拿著飲料，是 “smiling gently as she looks at the boy”；不是站著，是 “leaning casually against the car, hands in jacket pockets”。兩人的關係從這裡跑出來。
最後鋪氣氛：“autumn leaves scattering around them”、“long shadows in the afternoon light”。“warm tones against cool blue” 管配色，“nostalgic autumn mood” 管情緒。

三人團體圖：從翻車改到能用

人一多，每個都要看得出是誰。以下是學校走廊那張圖的完整除錯過程。

第一版

這一版只用身分稱呼角色，像是「班長」「排球隊長」。髮色瞳色的組合、服裝差異、有辨識度的配件、姿勢全都沒寫，模型只好給她們穿差不多的衣服。必須給每個人專屬的外型特徵。

第二版

Right in the middle of the hallway stands our class president, a confident girl with a chestnut brown ponytail that bounces as she moves. Her smart red-framed glasses catch the light as she checks her clipboard, the gold badge on her navy blazer shining proudly. She flashes a bright smile at the new transfer student beside her. This shy short brown haired girl keeps her black eyes downcast, nervously clutching a stack of books to her chest. Her oversized cream sweater practically swallows her small frame, the sleeves covering most of her hands. A little handmade rabbit charm dangles from her bookbag, swaying slightly with each hesitant movement. Behind them leaning casually against the lockers is the volleyball team captain. Her short blonde hair, still damp with sweat from morning practice, sticks slightly to her forehead. The red sleeves of her sports jacket are rolled up to her elbows, showing off toned arms. She’s got one knee bent with her foot propped against the lockers, that familiar competitive gleam in her green eyes even when she’s just relaxing between classes.

分得出來了，但還有三個問題：

排球隊長的姿勢在物理上做不到，膝蓋角度和站位都怪。
身高差太多，三個人看起來像不同年齡層。
彼此的距離感不自然。

第三版：只改兩個地方

先在開頭加一句把比例釘死：

“All three characters are of the same age and almost the same height.”

就這一行，同班同學之間的體型就不會亂跑。接著把隊長那個誇張姿勢改平實：

改前：“She’s got one knee bent with her foot propped against the lockers”
改後：“She’s leaning against the lockers”

運動員的個性留著，姿勢變成人做得出來的。

Tsubaki 提示詞還可以再調的三個地方

1. 把空間關係講死

改前：”Two boys feeding a cat outside”

改後：

Low-angle shot dominated in the foreground by a curious black cat, its tail curling around fallen autumn leaves as two teenage boys kneel on the sidewalk behind it. The orange-haired boy leans forward with an outstretched hand offering a treat, his unzipped black jacket revealing a rumpled white shirt underneath. Beside him, the black-haired boy watches through narrowed eyes, one hand resting on his knee while clutching a half-open food wrapper. Dappled sunlight filters through overhead trees, catching the dust motes around their playful interaction near a yield sign.

2. 把辨識特徵加強

改前：”Twin schoolgirls in uniforms”

改後：

Two teenage girls stand side by side in matching school uniforms, looking directly at the viewer with contrasting expressions. The girl on the left has short blue hair with colored inner streaks styled in a bob cut, featuring aegyo sal under her bright grey eyes. She wears a black serafuku with a white collared shirt, aqua necktie, and black pleated skirt, layered under a green jacket with sleeves extending past her wrists. Her companion has medium-length grey hair in a wolf cut with multicolored streaks, frowning slightly with her mouth closed while wearing an identical uniform with an aqua bow instead of a necktie. Both girls’ black sweaters peek from beneath their jackets, and their sleeves drape past their fingers.

順帶一提，aegyo sal 指的是臥蠶，來自韓系妝感的用語，模型有學到，直接寫就行。

3. 加互動線索

改前：”Two girls holding hands”

改後：

Two young women stand face-to-face in an intimate pose, their upper bodies visible against a clean white background. The first girl has long blonde hair styled in a low side ponytail, adorned with a green ribbon and delicate jingle bells. She wears black-framed glasses and a green camisole that reveals her bare shoulders and collarbone. Her green eyes gaze softly at the other girl, one hand resting gently on her companion’s shoulder. The second girl has short purple hair styled in twintails, with a grey camisole and matching hair ribbon. A small bell ornament decorates her hair between her eyes. She raises one hand up while interlocking fingers with the blonde girl’s other hand, creating a tender yuri atmosphere. Both wear subtle hair ornaments and maintain closed mouths with serene expressions. The simple composition focuses on their physical connection through held hands and shoulder contact.
