【qyn LoRA 使用说明】

一、触发词模板（照这个结构填）

qyn, 1girl, solo, blue eyes, <jacket?>, <景别>, <动作>, <服装>, <场景>

- blue eyes 属于触发词，请勿删除或改色

- solo 仅用于单人画面；画面里有男方时改成 1boy 或 1girl, 1boy

二、夹克开关（唯一换装轴）

- 默认机体服：不写 jacket

- 夹克形态：写 jacket

（jacket 是开关而非形容词，不要写 a little jacket / jacket open 这类半开描述，会把开关信号弄乱）

三、两套服装词（请逐字照抄，这是训练时的原句）

【机体服｜不写 jacket 时】

white bodysuit with black and white crossover neckline, red diamond gem on chest, orange trim lines, black and orange shoulder armor, black shorts, orange star patterns on thighs, white thigh-high stockings, orange high heels

【夹克形态｜写 jacket 时】

orange and white bomber jacket, black hood lining, orange round clasps with teal rings, open jacket,

white bodysuit with black and white crossover neckline, red diamond gem on chest, orange trim lines, black and orange shoulder armor, black shorts, orange star patterns on thighs, white thigh-high stockings, orange high heels

四、★ 强烈建议在提示词末尾追加 3D 渲染块

(high-poly 3D character model:1.4), (real-time game engine render, Unreal Engine 5 cinematic screenshot:1.4), (physically based PBR materials:1.35), subsurface-scattering skin with specular sheen and micro-normal detail, modeled hair cards with strand-level specular highlights, normal-mapped fabric weave with accurate roughness variation, soft ambient occlusion in every fold, clean metal reflections with sharp specular highlights, ray-traced soft shadows, clean anti-aliased edges, subtle bloom on the highlights, crisp focus

推荐负向：

flat 2D anime, cel shading without depth, hand-drawn illustration, sketch, painterly, watercolor, low-poly, plastic doll skin, waxy skin, real photograph, DSLR photo, film grain, real human pores

为什么：本 LoRA 的训练素材是干净的 3D 游戏角色渲染图。提示词里同时声明渲染方式，出图更接近训练素材的质感与配色；不声明时容易出成平面插画或实拍照片感。

五、LoRA 权重建议

0.85–1.0。若角色配色漂移（头发偏灰、服装变白），降到 0.75，3D 块保持不动。

六、已知限制（请务必了解）

1. 半脱 / 破损 / 解开类状态不稳定：训练素材里没有这类状态，直接写 unfastened / peeled down 常常无效（画面仍是穿好）或直接变全裸。

建议写法：状态前置 + 加权，并明细列出仍完整的部位，例如

(white bodysuit still worn:1.3), (bodysuit torn open at the chest:1.45), the rest of the bodysuit completely intact over her belly, hips and thighs

同时在负向加上：fully nude, bodysuit removed, peeled down, clean intact suit

仍不稳定时改用局部重绘：先出穿好衣服的图，再只蒙住需要露出的区域重绘（denoise 0.55–0.7）。

2. 构图越特写（close-up），服装越容易被模型简化或移除；full body 是最稳的景别。

3. 身份块（blue eyes / silver-white long braid with a red ring at each end / up-curled ahoge / black-and-orange star hair ornament）请勿改写，改写会导致脸不像。

七、示例（复制即用）

左例：qyn, 1girl, solo, blue eyes, full body, standing with hands on hips, calm expression, white bodysuit with black and white crossover neckline, red diamond gem on chest, orange trim lines, black and orange shoulder armor, black shorts, orange star patterns on thighs, white thigh-high stockings, orange high heels, plain light-gray studio, soft even lighting + 第四节的 3D 渲染块

右例：同左例，仅把 <jacket?> 位置改成 jacket，服装段换成第三节的夹克形态
