Reference-Locked Character Consistency

Properties

family

character-consistency

modality

reference image + text -> image

whyMultiModel

A base text-to-image model has no persistent identity; an identity adapter or trained LoRA injects the reference's features so the character stays consistent across prompts in a way a single model cannot.

steps

[object Object], [object Object], [object Object]

controls

Identity-adapter weight and scale; reference image quality; pose or control-net guidance; LoRA strength.

exampleStack

InstantID or IP-Adapter FaceID -> SDXL or FLUX -> GFPGAN/CodeFormer restore.

useCases

[Consistent characters across a storyboard][Brand mascots][Comic and graphic-novel panels]

pitfalls

Too-high adapter weight copies the reference pose and lighting (overfit); too low loses identity; identity drifts under extreme pose changes.
