公告中文翻译：
该功能与 “样式参考 “功能类似，只不过它不是匹配参考样式，而是尝试让角色匹配 “角色参考 “图像。
工作原理
在提示符后键入 –cref URL，并输入字符图像的 URL
您可以使用 –cw 将参考 “强度 “从 100 修改为 0
强度 100（–cw 100）为默认值，使用脸部、头发和衣服。
在强度为 0 时（–cw 0），它将只关注脸部（有利于更换服装/发型等）
适用范围
该功能在使用 Midjourney 图像制作的角色时效果最佳。它不是为真人/照片设计的（而且很可能会像普通图像提示一样使其变形）
Cref 的工作原理与常规图像提示类似，但它会 “聚焦 “于人物特征
此技术的精确度有限，无法准确复制酒窝、雀斑或 T 恤标志。
Cref 可用于 Niji 和普通 MJ 模型，也可与风格一致性 –sref 结合使用。
高级功能
您可以使用多个 URL 来混合多张图片中的信息/字符，例如 –cref URL1 URL2（这与多张图片或样式提示类似）
如何在网页版上使用？
将图片拖动或粘贴到输入框中，现在它有三个图标。选择这些图标可设置是图片提示、样式参考还是字符参考。Shift+ 选择一个选项，在多个类别中使用一张图片
请记住，虽然 MJ V6 还处于 alpha 阶段，但这些功能和其他功能可能会突然发生变化，不过 V6 正式测试版即将推出。
简单测试了下，并不是之前说的仅支持Midjourney生成的图片，外部图片也是可以的，对于一些名人名字+图片复刻的会更好些，上班了，晚上继续玩~
英文公告：
This is similar to the “Style Reference” feature, except instead of matching a reference style it tries to make the character match a “Character Reference” image.
How it works
Type –cref URL after your prompt with a URL to an image of a character
You can use –cw to modify reference ‘strength’ from 100 to 0
strength 100 (–cw 100) is default and uses the face, hair, and clothes
At strength 0 (–cw 0) it’ll just focus on face (good for changing outfits / hair etc)
What it’s meant for
This feature works best when using characters made from Midjourney images. It’s not designed for real people / photos (and will likely distort them as regular image prompts do)
Cref works similarly to regular image prompts except it ‘focuses’ on the character traits
The precision of this technique is limited, it won’t copy exact dimples / freckles / or tshirt logos.
Cref works for both Niji and normal MJ models and also can be combined with –sref
Advanced Features
You can use more than one URL to blend the information /characters from multiple images like this –cref URL1 URL2 (this is similar to multiple image or style prompts)
How does it work on the web alpha?
Drag or paste an image into the imagine bar, it now has three icons. selecting these sets whether it is an image prompt, a style reference, or a character reference. Shift+select an option to use an image for multiple categories
Remember, while MJ V6 is in alpha this and other features may change suddenly, but V6 official beta is coming soon.
We’d love everyone’s thoughts in ideas-and-features
We hope you enjoy this early release and hope it helps you play with building stories and worlds
