Kafka — Honkai: Star Rail · Krea 2 LoRA
触发词 / Trigger word： kafka
真人写实向的卡芙卡角色 LoRA，基于 Krea 2 (Krea 2 Raw) 训练。素材为 96 张真人 cosplay 实拍照片，因此权重出图天然带「棚拍/实景摄影」的质感，而不是插画风。
推荐参数
LoRA 权重：0.8 – 1.0（0.85 最稳；1.1 以上会开始偏饱和）
采样步数：24 – 30，CFG 2.5 – 3.0，采样器 er_sde / simple
分辨率：1024×1536（竖）或 1536×1024（横）
推荐提示词
kafka, full body, standing, hand on hip, looking at viewer, front view, wine red long hair, light purple eyes, black long coat, white dress shirt, red necktie, red belt, black slim pants, black knee-high boots, futuristic neon corridor, magenta and blue neon lights, night, cinematic lighting
角色固有特征（酒红长发 / 浅紫瞳 / 黑外套 + 白衬衫 + 红领带 + 红腰带）建议显式写进正向提示词，LoRA 会强化而不是替代它们。
适用场景
写实向角色出图、cosplay 风格写真
赛博 / 霓虹 / 夜场 / 科幻工业风场景
配合 ControlNet、img2img 做姿势与构图控制
注意事项
不要与 Illustrious / Animagine 系的 LoRA 混用，底模不同会互相破坏。
训练集含真人实拍照片，出图会保留部分摄影瑕疵（噪点、浅景深），这是刻意保留的写实感。
若出图脸崩或服装漂移，优先降低权重到 0.7–0.8，而不是加更多形容词。
English
Trigger word: kafka
A photorealistic character LoRA of Kafka from Honkai: Star Rail, trained on Krea 2 (Krea 2 Raw). The dataset is 96 real cosplay photographs rather than illustrations, so generations naturally carry a studio / on-location photography look.
Recommended settings
LoRA weight: 0.8 – 1.0 (0.85 is the sweet spot; above 1.1 colors start to oversaturate)
Steps 24 – 30, CFG 2.5 – 3.0, sampler er_sde / simple
Resolution 1024×1536 (portrait) or 1536×1024 (landscape)
Example prompt
kafka, full body, standing, hand on hip, looking at viewer, front view, wine red long hair, light purple eyes, black long coat, white dress shirt, red necktie, red belt, black slim pants, black knee-high boots, futuristic neon corridor, magenta and blue neon lights, night, cinematic lighting
Notes
Do not mix this with Illustrious / Animagine LoRAs — different base model will degrade both.
Trained on real photography, so expect genuine photographic texture (grain, shallow depth of field) rather than a clean illustration finish.
If the face breaks or the outfit drifts, lower the weight to 0.7–0.8 instead of adding more adjectives.
