Nano Banana Pro Character Consistency: A Series Without Drift
The biggest fear when making brand character posts, picture-book pages, or a social series is the character changing by the second image. This prompt separates 'locked' elements from 'variable' ones: the face, fixed features, and style stay locked while only the pose and setting change per image. Generate one image at a time, reusing the same opening instructions, to keep the whole series stable.
以我上傳的角色參考圖為基準生成新圖,必須是「同一個角色」。 鎖定不變(每一張都相同): - 臉部特徵與五官比例與參考圖完全一致 - 固定特徵:[角色固定特徵] - 視覺風格:[視覺風格],整個系列使用相同色盤、相同筆觸與光線邏輯 本張新內容(唯一可變的部分): - [這張的動作與場景] 規則: 1. 允許鏡頭角度、構圖、表情變化,但不可改變角色長相與身材比例 2. 一次只生成這一張;我會用同一段開頭逐張生成整個系列 3. 比例固定 [圖片比例],主體在畫面中的大小於系列間保持接近
Swap the variables inside the [ ] brackets for your own content, then paste into Nano Banana Pro (Gemini).
No other tool needed — run this prompt right here and see the result (edit the text and swap the [variables] first if you like). History lives in My generations.
Officially, Pro supports up to 14 reference images, with up to 6 usable for high-fidelity character locking — in practice, one clear front-facing reference image already goes a long way. The trick is splitting the prompt into a locked section and a variable section: the vaguer the prompt, the vaguer the output, so the more specific the locked section (hairstyle, accessories, color palette), the lower the drift rate. Generating one image at a time is much more stable than requesting four at once; if a particular image's face comes out wrong, just regenerate that one image rather than going back to edit the locked section.
[角色固定特徵]例:「短黑髮、圓框眼鏡、米色風衣、帆布鞋」
[視覺風格]例:「扁平插畫」「水彩手繪」「皮克斯式 3D」
[這張的動作與場景]例:「在夜市攤位前吃魷魚羹、表情滿足」
[圖片比例]例:「1:1」「4:5」「16:9」
