  • What are the limitations of the character reference function?

    -The character reference function may not perfectly capture all features of the reference image, especially facial expressions and poses. It often requires multiple attempts to get a naturally looking face, and the results can be quite different from the original image for fantasy characters.

  • How can the web interface of Mid Journey be used for character reference?

    -The web interface allows users to upload an image and automatically add it to the prompt area. Users can adjust various settings such as ratio, stylization, and speed in the settings tab, and these are automatically added to the prompt.

  • What are the advantages of using the character reference function?

    -The character reference function allows for consistent character generation and the ability to change settings like clothing and environment without having to redescribe the character each time.

  • What was the result when the user tried the character reference function with their own photo?

    -The result was not satisfactory as the generated image did not resemble the user, indicating that there is room for improvement when using the function with real-life photos.

  • How does the character reference function perform with fantasy characters?

    -The function can produce varied results with fantasy characters. While some similarities may be retained, there can be significant differences in features, suggesting that alternative methods like stable diffusion with a high IPA value might yield better results for certain fantasy character poses and situations.
