Midjourney parameter: Character Reference

A Character Reference allows you to recreate a specific character in multiple images. By using a picture of a character you like, Midjourney can recognize the character's features, like hair color, clothes, and facial traits, and use these details for generating the character in new scenes. This helps maintain consistency across different images. https://docs.midjourney.com/hc/en-us/articles/32162917505293-Character-Reference
