Midjourney's CREF (Character Reference) feature allows you to generate consistent character depictions across multiple images by providing a reference image.
To use CREF, add the --cref parameter to your prompt followed by the URL of the character reference image you want to use. For example: "/imagine prompt --cref https://example.com/character.jpg"
The --cref parameter ensures the generated images adhere to the character traits of the provided reference image, maintaining a consistent appearance. This is useful for storytelling, branding, and creative projects.
You can adjust the fidelity of the generated image to the reference using the --cw (character weight) parameter, which ranges from 0 to 100. Higher values make the generated image more closely match the reference.
For best results, use clear, high-quality, AI-generated images as references, such as previous Midjourney outputs. Photos of real people may lead to distortions.
You can provide multiple character reference images in one prompt by separating their URLs with spaces.
The --cref parameter currently only works with Midjourney's v6 model. It is a new feature that may have some limitations and bugs in its initial release.
So in summary, Midjourney's CREF feature allows you to maintain consistent character appearances across images by providing a reference image, giving you more control over character depiction in your creative projects.
