Image LoRA Bleeding: Why Unrelated Objects Inherit Trained Traits

FourtyMichaelMichael · reddit · 2026-07-31

A user encountered severe feature bleeding while training a LoRA for a specific vehicle. Even after adjusting epochs (from 10 to 100), other unrelated vehicles in the generated scene were forcibly applied with the LoRA's traits (e.g., tire styles).

The author noted that character LoRAs sometimes suffer from similar issues (e.g., mixing facial features between subjects), while some high-quality LoRAs can perfectly isolate the target. They speculate this isn't just overfitting, but rather poor captioning causing the model to incorrectly generalize conceptual traits, and are seeking root causes and solutions from the community.
