Firefly (Hotaru) Wallpaper Generator

High-quality SDXL workflow to generate 1920×1080 wallpapers of Firefly (Hotaru) from Honkai: Star Rail. SFW fan art, clean lighting, lean negatives, refiner pass, and subtle post-processing for crisp results.

Features

• SDXL Base + Refiner, native 2048×1152 → downscale to 1920×1080
• Lean negative prompts to avoid over-suppression
• Optional LoRA (character-accurate) and subtle noise/sharpen post-process
• DPMSolver scheduler, VAE slicing, xFormers (if available)

Requirements

• Python 3.9+
• GPU with CUDA recommended
• pip packages: see requirements.txt

Install

python -m venv .venv && source .venv/bin/activate  # on Windows: .venv\\Scripts\\activate
pip install -r requirements.txt

Usage

python generate_firefly_sdxl_hq.py

The output will be firefly_hotaru_wallpaper_1920x1080.png.

Notes

• This is fan art. Keep it SFW and avoid logos/watermarks.
• If you have a Firefly LoRA, set LORA_PATH and LORA_SCALE in the script.
• For maximum crispness, generate at 2048×1152 and downscale to 1920×1080.
