Fizgig LoRA Isolation: 0/50 face bleed-through vs 48/50, likeness kept
shootthesound · reddit · 2026-10-17
Fizgig v8.4.0 introduces LoRA Isolation, fixing the classic problem where a person-LoRA paints its subject's face onto everyone else. On Krea 2 with identical settings: a normal LoRA bled onto 48/50 strangers, isolation onto 0/50, with subject likeness nearly unchanged (ArcFace 0.78 vs 0.77). The trick: train two identities together (built on DOP from Ostris's AI-Toolkit, plus multi-subject anchoring, fused-token class decoupling, in-frame negative pairs with causal-order captions). Tips, setup video and release notes are all free and open source.
