角色设定卡提示词:一个角色、三个视角、一张图

Template — replace the four [BRACKETED] parts

Character reference sheet of one consistent character on a seamless neutral grey (#808080) studio background, clean editorial layout, landscape composition read left to right, split into three unequal vertical panels: PANEL 1 takes the entire left half of the frame (50% of the width); PANEL 2 and PANEL 3 share the right half at 25% each. Same identity, outfit, lighting and colour grading in every panel. No text, no labels, no logos, no watermark.

PANEL 1 (left half, by far the largest): chest-up portrait, straight front view, head and upper chest filling the panel, eyes in sharp focus with soft catchlights, [EXPRESSION] expression.

PANEL 2 (25% width, narrow): full-body side profile, standing relaxed and straight, arms hanging naturally, weight evenly balanced, head to toe inside the frame with even margins, showing silhouette, posture, garment volume and shoe profile.

PANEL 3 (25% width, rightmost): full-body back view, same standing pose, head to toe, showing how the hair falls, back posture, how the outfit fits from behind, and the shoe heels.

The two full-body figures share one scale: tops of the heads and soles of the feet sit on the same horizontal lines. Exactly one character, no duplicate figures, no other people, no background objects.

CHARACTER (identical in every panel): [age, height, build, face shape, eyes, nose, lips, skin, hair, overall demeanour]

WARDROBE (identical in every panel): [top, visible under-layer, bottoms, shoes, one accessory]. No handheld objects, no props.

LIGHTING & RENDER: [pick one style preset below]

Style preset A — photoreal studio

LIGHTING & RENDER: soft even studio lighting, large diffused key light with gentle fill, soft natural shadows, no harsh highlights, true-to-life skin tones, neutral white balance, polished editorial model-sheet look, full-frame camera with an 85mm lens look, deep focus with the whole figure sharp in every panel, realistic pore and fabric texture.

Style preset B — anime / manga

LIGHTING & RENDER: clean anime illustration style, crisp black line art with varied line weight, flat cel shading with soft gradient shadows, limited but vivid colour palette, no photorealism, consistent line quality and colour in every panel.

Style preset C — 3D animated feature

LIGHTING & RENDER: stylized 3D animated feature-film character render, appealing exaggerated but coherent proportions, soft subsurface skin, detailed hair groom and cloth, soft global illumination with three-point studio lighting and a gentle rim light, deep focus in every panel. Original character design, not resembling any real person or existing copyrighted character.

什么是角色设定卡?

在一张图里从几个角度展示同一个角色 —— 通常是正面、侧面、背面 —— 每个视角的脸、服装和光线都一致。它是让角色在插画、3D 模型或 AI 生成场景里保持一致的参考。本页模板用的是一张大幅正脸胸像加全身侧面和背面。

正面、侧面、背面三视图的提示词怎么写最好?

先点明是设定卡,再用数字把版式定死,最后才写角色。上面的模板先写「character reference sheet」,把画布按 50/25/25 分开,要求正脸胸像、全身侧面、全身背面,让头顶脚底对齐,禁掉文字和道具,然后才填角色、服装和渲染风格。

哪个 AI 模型最适合做角色设定卡?

能听懂长而结构化的提示词、版式渲染得干净的模型。在 apimodels.app 上,这个模板已经在 gpt-image-2.5-sunburst 上以 2048x1152 跑过几百次,每张约一分钟;gpt-image-2.5-flare 是更快更便宜的一档,适合打草稿。

怎么让每个视角里的角色完全一致?

用具体、可核对的特征描述角色,服装限制在五件、只要一件配饰,禁掉道具,并在角色和服装两块都写上「identical in every panel」。描述越具体,模型在几个视角之间能改动的余地就越小。

生成一张角色设定卡要多少钱?

在 apimodels.app 上用 gpt-image-2.5-sunburst:2K(2048x1152)默认 high 画质一张 $0.04,medium $0.025,4K high $0.08。生成失败不扣费。

能用自己的照片做设定卡吗?

可以 —— 用 gpt-image-2.5 的图像编辑端点传入你的照片,沿用同一个模板,把角色那一块换成「参考图里的这个人」。只对你自己或已经同意的人这样做。
