⚙️ Recommended Settings & Tips

• LoRA Weight: 0.85 - 1.0 (The gradient hair and dark skin are mandatory anchors; high weights ensure the blonde-to-brown transition is smooth and doesn't look like random patches).
• Base Models: Optimized for Illustrious XL and Pony Diffusion V6 XL.
• Skin & Lighting: Use dark skin, tan, and shiny skin to make her complexion pop against her light-colored hair and outfits.
• Pro-Tip: Mei's personality is very expressive. Use tags like :d, ;\), open mouth, and blush. For her hair, always include both blonde hair and brown hair alongside gradient hair to ensure the specific Straylight color scheme is maintained.
