Why Fictional Character LoRAs Get That Plastic Look
ankar37 · reddit · 2026-07-11
While training a LoRA for a **fictional AI character**, the author encountered an issue: enabling the character LoRA alongside a realism LoRA causes the images to lose their lifelike quality, making the skin look smoother, more plastic, and generally more "synthetic." The author experimented with different strengths: - **Low strength**: Better realism, but the character's identity begins to drift. - **High strength**: The character looks more like the intended design, but the plastic and synthetic feel is stronger. They added that the training set for this character was built from a few reference images expanded using AI generation, which differs from training LoRAs for real people or celebrities. Therefore, they are seeking advice on whether the dataset and training approach should be rethought for fictional characters relying on "AI-generated reference images."
