If your character looks perfect in the preview, but the final image changes the face… it’s usually not your LoRA. Most of the time it’s Hires.fix / Upscale denoise re-drawing the face during the second pass. ✅ What to do - Keep your LoRA weight the same (ex: 0.35–0.55) - Lower Hires denoise so the upscale doesn’t “recreate” the identity 🎯 My go-to SDXL settings - Upscale: 1.3x – 1.7x - Hires steps: 10–15 - Hires denoise: 0.20 – 0.35 (this is the magic range) - If you go 0.45+, expect face drift and “AI beauty” artifacts Why it works: Low denoise = the upscale keeps your existing face/details. High denoise = it invents new features and your character “drifts”.
