MOSS-Image-Base (5B) - BAStyle LoRA (v1.0)

A BF16 Blue Archive style clean cel-shaded illustration LoRA trained on OpenMOSS / MOSS-Image-Base (5B).

OpenMOSS / MOSS-Image-Base (5B) 的 BF16 蔚蓝档案风格清透赛璐璐画风 LoRA。

Overview / 简介

• Style & Scene Coverage: Covers both close-up Memorial Lobby portraits and even-lit story cutscene CGs (multi-character group scenes, lone character overlooking a cityscape, campus architecture, and daytime/nighttime skies).
  除近景纪念大厅插画外，同样支持清爽平光的剧情过场 CG（多人日常同框、单人背影远眺）以及学院建筑、昼夜天空等背景空景。

• Feature Decoupling & Prompting Tips:

• Halos: Not baked into the trigger word. Describe halo color and shape when desired; omit halo terms for halo-free characters.
  光环按需控制：需要光环时描述颜色与形状；不写光环词汇时默认不出光环。

• Pure Empty Backgrounds / Skies: When generating scenes with no people in the frame, include 2D anime background illustration in the opening clause (instead of photographic shot) so the base model does not fall back to realistic photography. Add with faint concentric rings to summon the signature ringed sky.
  画面无人物的纯建筑或天空空景建议在开头加入 2D anime background illustration 以避开底模写实摄影先验；描写天空时加入 with faint concentric rings 可生成原作标志性的同心圆环天空。

• Frozen Text Encoder: Trained on the DiT only (Rank 32 / Alpha 16, BF16) with Qwen3.5-9B frozen, preserving native natural-language prompt adherence and in-image text rendering.
  冻结 Qwen3.5-9B 仅训练 DiT，保留底模原生的中英文自然语言理解与文字生成能力。

• Dataset: 58 high-resolution illustrations captioned with high-quality natural-language descriptions via Gemini 4 Carbon, with manual verification of edge cases (in-image text and halo annotations).
  58 张高清插画采用 Gemini 4 Carbon 高质量自然语言打标，并人工核实了部分细节问题（重点排查了画面内文字与光环标注）。

Verified Sample Prompts / 实机验证示例提示词

1. Memorial Lobby - With Halo (纪念大厅 · 带光环)

bastyle, An eye-level medium shot of a quiet girl with long dark-violet hair, warm amber-red eyes, and a thin glowing pale-pink geometric halo above her head sitting by a tall sunlit library window, holding a closed hardcover book against her chest and looking calmly toward the viewer.

2. Memorial Lobby - Without Halo (纪念大厅 · 无光环)

bastyle, An eye-level medium close-up shot of a gentle girl with flowing silver-white hair, luminous sapphire-blue eyes, and a small navy hair ribbon leaning over a sunlit seaside boardwalk railing at golden hour sunset, smiling softly back toward the viewer as the warm sea breeze lifts her hair and red neck ribbon. She wears a crisp cream cardigan over a white school shirt, bathed in translucent amber-gold sunset rim light from the upper left against sparkling ocean waves and pastel orange-and-violet twilight clouds.

3. In-Image Text Rendering (画面内英文写字)

bastyle, A slight low-angle medium close-up shot of an energetic blonde wolf-eared girl with bright emerald-green eyes, a playful fang smile, and a glowing golden star-ring halo floating above her head standing on a breezy school rooftop under a crisp azure sky with fluffy cumulus clouds, holding up a small wooden cafe chalkboard cleanly written in neat white chalk text "After-School Sweets!" with a cute doodle star beside it, wearing an open pastel-mint hoodie over a white blouse with bright afternoon sunlight from the upper right.

4. Story Cutscene CG - Lone Overlook (单人背影远眺城市过场)

bastyle, A wide eye-level shot from behind a lone girl with long silver-blue hair in a navy school cardigan standing at a metal observation deck railing in the right foreground, looking out across a sprawling coastal city, harbor bridges, and distant mountain ridges under a calm late-afternoon sky, lit by gentle natural daylight from the upper left.

5. Story Cutscene CG - Multi-Character Group (平光多人街头过场)

6. World Background - Campus Architecture (学院建筑无人空景)

bastyle, A symmetrical eye-level wide 2D anime background illustration across a clean white stone plaza and classical colonnade courtyard leading toward a grand modern-gothic academy clock tower and glass-walled campus buildings under a clear blue sky with faint concentric rings, crisp cel-shaded architectural linework and clean cast shadows across pale stone pavement, no people in the frame.

7. World Background - Daytime Ringed Sky (白天同心圆环天空)

bastyle, A low-angle wide 2D anime background illustration looking up past a painted school rooftop railing and wire fence into a vibrant clear cyan-blue daytime anime sky filled with painterly white cumulus clouds and giant faint concentric halo rings across the upper sky, bright clean anime daylight, no people in the frame.

Known Limitations & Roadmap / 已知问题与后续计划

• Facial & Eye Proportions in Standalone Generation: Because the v1.0 dataset includes a high proportion of wide story cutscene CGs and multi-character scenes (with relatively few open-eye facial close-ups) and uses high-noise-weighted timestep sampling (logit_mean = -1.09), generating generic original characters standalone may occasionally retain the base model's older anime / classic galgame facial proportions and glossy eye gradients.
  由于 v1.0 数据集中远景剧情过场与多人场景占比较高（睁眼正脸特写样本较少），且时间步采样偏向高噪构图区间，单跑生成原创路人角色时，人物脸型比例与眼瞳高光偶尔仍会带有底模原生的早期二次元 / 古早 Galgame 感。

• Current Workaround: For more consistent modern character faces in v1.0, consider pairing this style LoRA (strength = 0.85 - 0.90) with your own character LoRA, or explicitly specifying facial and eye traits in the prompt.
  当前建议：若对人物五官画风要求较高，建议自备角色 LoRA 叠加使用（本画风 LoRA 权重设为 0.85 - 0.90），或在提示词中具体描述脸型与眼型细节。

• Planned Fix: Future updates (v2 / portrait refinement patch) will expand open-eye close-up portrait samples, refine facial feature annotations, and rebalance low-noise timestep sampling to improve standalone character facial fidelity.
  后续计划：未来版本将补充睁眼正脸近景样本、细化五官结构标注并优化中低噪区间采样，修复单跑人物五官偏古早的问题。
