Dusk Qingyuyan / 夕・青玉砚 - WAI / Illustrious SDXL Character LoRA

This is a WAI / Illustrious-SDXL character LoRA for a Dusk-inspired original variant, trained with the trigger dusk_qingyuyan.

It is designed to recall:

long black hair with teal streaks
red eyes
dragon-girl features
teal antler-like horns
pointed ears
layered white and turquoise hanfu-style outfit
sheer teal outer robe
dark teal / black outer layer
wide sleeves
red cords, teal ribbon, jade ornaments and tassels
bare legs and black ankle-strap heels

The LoRA is strongest for identity, outfit, hairstyle, horns, ears and the overall teal-white visual motif. It works best on WAI / Illustrious-based SDXL checkpoints.

Recommended Usage

Default Weight

0.7

This is the best balance found in evaluation. It gives stable identity and outfit recall without too much background or accessory pollution.

Useful Range

0.6 - 0.8

Motion / Composition First

0.35 - 0.55

Use lower weight when the pose, motion or background is more important than maximum character fidelity.

Avoid as Default

0.9 - 1.0

High weights strengthen identity, but can also over-emphasize teal tail-like or weapon-like shapes, lock the composition, and reduce prompt obedience.

Recommended Generation Settings

These settings were used for evaluation:

Checkpoint: WAI-Nsfw-Illustrious-17
Resolution: 1024 x 1024
Sampler: Euler a
Steps: 28
CFG scale: 6.0
Seed: 2026062801 for sample images

Other Illustrious / WAI-compatible SDXL checkpoints should work, but the exact character recall may vary.

Known Limitations

The LoRA intentionally uses dusk (arknights) as a character anchor, so it inherits some Dusk / WAI prior knowledge.
High weights can produce teal tail-like or weapon-like forms.
Dynamic poses may be pulled back toward front-facing standing or seated compositions.
Lower weights improve pose freedom but weaken identity and outfit precision.
This model is primarily intended for WAI / Illustrious SDXL. Cross-family compatibility with Pony, realistic XL or non-Illustrious models is not the target.
