Vertical slit pupils for Krea 2.
Krea 2 does not render this feature: asked directly for "vertical slit
pupils" it returns ordinary round human pupils on every seed tested.
This LoRA adds it.
Trigger: sltp1
HOW IT BEHAVES
The effect applies whenever the LoRA is attached, largely regardless of
whether the trigger word is in the prompt. Measured: at weight 1.0 the
slit pupils appear with and without sltp1. Attach it when you want the
feature, detach it when you don't. Lower weights (0.6-0.8) soften it.
TRAINING
· Base: Krea 2
· 48 synthetic images, close-up portraits, 512px
· 600 steps, rank 32, batch 1
· Captions describe medium, framing, subject, hair, eye colour, pose,
expression, clothing, setting and lighting — everything EXCEPT the
pupil shape, so the token carries it.
The dataset varies sex, age, iris colour, hair and background on purpose,
so those are not baked in. Iris colour follows your prompt.
NOT trained on any real person. All source images are synthetic.
KNOWN LIMITS
· Extreme macro of a single eye loses the effect — the pupil comes back
round. Render a portrait and crop instead.
· The trigger is a rare token and is occasionally drawn as lettering on
caps or signs. Add "no logo, no lettering" if it shows up.
