This is my first Chroma lora trained using OneTrainer at 512 resolution, about 1500 steps and rank 4, alpha 1, took a couple of hours on a 3060 12GB locally. A former experiment at rank 16, 3000 steps, and about 5 hours of training has failed. Chroma seems to learn very well at low ranks.
To use this lora, you should use natural language prompts like this:
asian male with long, dark hair. He is wearing a V-shape deep blue robe with wide sleeves, cinched at his waist by a belt. He is wearing a white, pleated undergarment and a high-collared shirt. He wears a white, rectangular headpiece. He wears gray chinese bootsThis prompt should be enough to give you his full likeness.
