Train a Flux LoRA of one character and reuse it across every scene
setuproll@setuproll88.0Overall score
A training-plus-inference pipeline that fine-tunes a Flux LoRA on 15 to 25 photos of one face, mascot or product, then loads it in ComfyUI so the subject stays identical across poses and backgrounds. For game artists, brand mascots and creators who need a repeatable character, not a one-off.
