Intended to generate a multipart sequence where a male character shifts into a female character. Works best with a simple background and highest resolutions. It is suggested to upscale the resolution as high as possible. You can use multiple prompts, such as pants, red hair, etc to describe characters, with more masculine prompts getting applied to the male character or vice-versa.
