1. Why Hires.Fix Matters in AI Art Generation
Hires.fix (High Resolution Fix) solves the "plastic skin" effect in AI-generated images through:
Upscaling images from 512x512 to 2048x2048 while maintaining sharp facial features and texture details
Repairs distorted hands/eyes in 93% of cases
Reduces VRAM usage by 40% vs traditional upscalers
Preserves original artistic style during enlargement
2. Step-by-Step: Hires.Fix Workflow in Krita AI
Phase 1: Initial Generation
① Open krita-ai-tools → Select "FLUX/SD3.5" tab
② Set base resolution to 768x512 (16:9 ratio)
③ Generate image with prompt: "(8k RAW photo:1.3)"
Phase 2: Hires Activation
④ Click "Advanced Options" → Enable "Hires.Fix"
⑤ Choose upscaler: R-ESRGAN 4x+ or Latent Diffusion
⑥ Set denoise strength between 0.3-0.5
⑦ Adjust "Upscale by" slider to 2x or 4x
3. Pro Tips for Perfect Results
?? Texture Preservation
Use "ControlNet Tile" when upscaling oil painting styles
?? Speed Optimization
Enable "TAESDXL" decoder for 2x faster processing
?? Hardware Tweaks
Allocate 4GB+ VRAM through krita-ai's performance panel
4. Solving Common Hires.Fix Issues
