SBBT is a body-type LoRA for Krea 2. It trains a proportion: a slim frame carrying a large bust. It is not about breast quality or anatomical detail.

Trigger word is SBBT and it works best at the front of the prompt.

Prompt shape:

SBBT, [framing + capture type] of [subject: skin, hair, build, expression] in [environment], her [round/teardrop/perky] [large/massive] breasts with [colour] areolae, [lighting]. [background].

Run it at 0.9 on its own.

Trained on Krea 2 raw. The captions describe covered chests as well as bare ones, so clothing behaves as a conditional: prompt a top and you get spill and strain rather than noise.
