About this LoRA

Jem Hadar 1

A character LoRA for Krea 2. Reproduces a consistent subject across poses, framing, and lighting.

Usage

Include the trigger word jmhdr1 in your prompt.

Recommended weight: 0.7. At weight 1 this LoRA also pulls other people in the image towards this character: ask for someone else and you may still get this face. At 0.7 the likeness holds and the rest of your prompt is respected. If you need a stronger likeness, go up in small steps.

Two character LoRAs at once tend to blend, especially when the two characters look alike. For two characters in one image, generate them one at a time.
