Revisions

• v1b (2023-02-12)
  • Resized v1 from network rank 128 >>> 32. This has no negative impact on image quality/coherency, and provides these advantages:
    • Reduced LoRA file size from 144mb to 36mb
    • Slightly reduced overfitting on training data
      • Less darkening/vignetting of backgrounds
      • Improved color saturation
      • Halo is a bit more consistent
      • Seia's hair gets confused with details on her clothing less frequently
