Rainmaker Illutrious — Booru-tag-Based Model Instruction

0) Overview

Type: High-quality anime/stylized image generator.
Strengths: Works best with structured tag prompts. Preloaded with 1600+ anime characters (callable by name tags). Supports artist/style tags for stylistic control. Extremely responsive to negative prompts for quality filtering.

1) Input / Output Format

Input

Positive Prompt (pos): Comma-separated tag list with optional weight (tag:weight).
Negative Prompt (neg): Comma-separated tags for suppression.
Params: resolution, steps, guidance, sampler, seed.

Output

Model returns image(s) faithful to tags, weights, and parameters.

2) Prompt Construction Rules

2.1 Positive Prompt (pos)

Always start with quality tags: best quality, amazing quality, very aesthetic, absurdres, {{{masterpiece}}}
Add style tags with weight if needed: (chiaroscuro:1.2), (ciloranko:0.8), (ke-ta:0.9), (ningen mame:1.1)
Add subject + details: 1girl, pink eyes, white long hair, black_skin, black shirt, purple tie, black shorts, very loose black coat with purple decorations
Add scene/environment tags: apocalypse background, holding rapier, cool mood
Separate with commas, avoid natural language sentences.

2.2 Negative Prompt (neg)

Use a concise, powerful set:

text, watermark, censored, bar_censor, split, 3d, lowres, (worst quality:1.2), (bad quality:1.2), bad anatomy, bad hands, sketch, jpeg artifacts, signature, old, extra head, conjoined, multiple views

Deduplicate tokens.
Use weight on worst/bad quality to strongly suppress them.
Add specific negatives (extra fingers, deformed hands) if needed.

2.3 Parameters

Recommended defaults:

resolution = 1536x2048 steps = 28~32 guidance = 5.5~6.5 sampler = Euler a / DPM++ 2M Karras (preferred) seed = auto (or fixed for reproducibility)

3) Example

pos:

best quality, amazing quality, very aesthetic, absurdres, (ciloranko:0.78), (rhasta:0.9), tidsean, (ke-ta:0.9), (chiaroscuro:1.27), (ningen mame:1.1), {{{masterpiece}}}, 1girl, pink eyes, black_skin, white long hair, black shirt, purple tie, black shorts, very loose black coat with purple decorations, apocalypse background, holding rapier, cool mood, masterpiece

neg:

text, watermark, censored, bar_censor, split, 3d, lowres, (worst quality:1.2), (bad quality:1.2), bad anatomy, bad hands, sketch, jpeg artifacts, signature, old, extra head, conjoined, multiple views

params:

resolution = 1536x2048 steps = 30 guidance = 5.5 sampler = auto seed = auto

✅ Key Points

Keep tag format, no full sentences.
Use weights (tag:1.x) to boost style elements.
Always include quality stack and negative prompt cleanup.
Characters from built-in DB can be called simply by name tag, e.g. asuka_langley, (asuka_langley:1.1)
Artist styles only if explicitly requested: (by kei:1.0), (by mikoto_shinkai:1.0)
