怎么让Midjourney画出一条腿的鸟？

这几天想做个山海经题材的AI视频。
我想到的选题是“毕方引火”的故事。
“毕方”是一种只有一条腿的鸟，《山海经·西山经》记载：
"有鸟焉，其状如鹤，一足，赤文青质而白喙，名曰毕方，其鸣自叫也，见则其邑有讹火。"

让AI根据这段描述，设计了“毕方”的形象：

整体: 形似鹤，但体型更大，姿态更加威严，浑身燃烧着熊熊烈焰，散发出神秘而强大的气息。
头部: 鹤首，白喙，头顶有一簇金红色的翎羽，如同火焰在燃烧。
眼睛: 金红色，炯炯有神，目光中带着一丝威严和一丝悲悯。
翅膀: 宽大有力，羽毛呈现青蓝色，边缘燃烧着火焰，仿佛随时可以展翅高飞。
脚: 只有一只脚，呈现赤红色，如同烧红的烙铁，踏在地上会留下火焰的痕迹。
装饰: 身上装饰着一些古朴的纹饰，例如火焰纹、云纹等，增添神秘感和上古气息。

提示词如下：

/imagine
A majestic crane-like creature with a single leg, engulfed in blazing flames, exuding an aura of ancient power and mystique.

Details:

• Head: Crane-like with a white beak, a crown of golden-red plumes resembling burning flames.
• Eyes: Piercing golden-red eyes, radiating both authority and compassion.
• Wings: Broad and powerful, feathers a mix of cyan and blue, edges flickering with flames.
• Leg: Single, crimson red leg, resembling a burning iron, leaving fiery trails where it steps.
• Body: Decorated with ancient patterns like flame and cloud motifs, adding to its mystique and archaic aura.

Style:

• Inspired by ancient Chinese mythology and Shan Hai Jing aesthetics.
• Epic and dramatic, emphasizing the creature's divine and awe-inspiring presence.
• Color palette: Dominated by reds, oranges, and yellows for the flames, contrasted with deep blues and greens for the feathers.
• Intricate details and textures, capturing the essence of an ancient mythical being.

然后MJ画出的图是这样的

说好的一条腿呢？

修改提示词，明确地强调只有一条腿

/imagine
A majestic crane-like creature with a single, crimson red leg, engulfed in blazing flames, exuding an aura of ancient power and mystique, standing amidst a burning forest.

但是MJ很顽固，依然只肯画两条腿的“毕方”。

再换提示词，这是进化/变异成一只脚的鸟，看能不能“骗”过MJ：

/imagine
一只形似鹤的生物，浑身燃烧着火焰，经过神秘的进化/变异，只有一条赤红色的腿，如同烧红的烙铁，散发着古老而强大的气息，矗立在燃烧的森林中。

结果是给我进化成了三条腿。

变着花样换各种表述，各种风格的提示词，

偶尔会出现一张一只脚的鸟，但是无法复现。

是不是提示词太复杂了？我们来测试 MJ 能否画出一只脚的鸟，暂时去掉其他关于毕方的描述。

直接描述法：

/imagine A bird with one leg, standing on a branch.

强调法:
/imagine A bird with one leg, standing on a branch --no two legs

变异/进化法:
/imagine A bird that has evolved/mutated to have only one leg, standing in a forest.

拟人化法:
/imagine A bird, like a pirate with a peg leg, hopping on one leg on a beach.

艺术化法:
/imagine A surreal image of a bird with a single leg, balanced on a sphere, floating in the sky.

种种不同的提示词，MJ 都不能够理解并生成只有一条腿的鸟的图像。

很有可能 MJ 的训练数据中缺少单腿鸟的样本，导致它难以理解并生成相应的图像。

我尝试换一个思路，引导 MJ 将其理解为两种生物的进化融合，例如鸟和蛇或鸟和鱼的结合，看看MJ 能否理解，并如愿生成一条腿的鸟？

鸟类和蛇类的融合:
/imagine A fantastical creature, a fusion of a bird and a snake, with the upper body of a bird and a single, powerful, serpentine tail instead of legs, perched on a branch.

鸟类和蛇类的融合:
/imagine

A fantastical creature, a fusion of a bird and a snake, with the upper body of a bird and a single, powerful, serpentine tail instead of legs, perched on a branch.

鸟类和鱼类的融合:
/imagine A mythical creature, a hybrid of a bird and a fish, with the wings and feathers of a bird and a single, long, fish-like tail instead of legs, swimming through the air.

腿变没了。

结合神话元素:
/imagine A creature from ancient mythology, a bird-like being with a single, strong leg ending in a serpent's tail, standing proudly on a rock.

我们用 “fusion” 或 “hybrid” 来描述两种生物的结合。
用 “upper body” 或 “wings and feathers” 来描述鸟类的特征。
用 “serpentine tail” 或 “fish-like tail” 来描述取代腿部的部分。
结合一些神话元素，例如 “ancient mythology” 或 “mythical creature”，以增强画面的奇幻感。
以上种种，都没能骗过MJ，画出一条腿的鸟。

再尝试以下几种新的思路：

强调 “进化/变异” 的结果: 强调 “进化/变异” 导致鸟类失去了一条腿，并用更具想象力的语言来描述这种变化，例如：
/imagine A bird, sculpted by the forces of evolution, now stands tall on a single, powerful leg, a testament to its remarkable adaptation. Its other leg, lost to the ages, is but a whisper in its genetic memory.

结合 “魔法/诅咒” 的元素: 尝试用 “魔法” 或 “诅咒” 的元素来解释鸟类只有一条腿的原因，例如：
/imagine

A bird, touched by ancient magic, now walks the earth on a single leg, a testament to the power of forgotten spells. Its missing leg, a sacrifice to the mystical forces, has granted it unique abilities.

模糊腿部的概念: 以尝试用模糊的语言来描述腿部，例如：
/imagine

A bird, its form defying conventional anatomy, stands gracefully on a single, strong appendage, a testament to the boundless possibilities of nature's creativity.

使用 “残疾/受伤” 的概念: 尝试用 “残疾” 或 “受伤” 的概念来描述鸟类只有一条腿的情况，例如：
/imagine A resilient bird, a survivor of a past battle, stands proudly on its remaining leg, a symbol of strength and perseverance. Its lost leg, a reminder of its past struggles, has only made it stronger.

总算在生成的四张图中，出现了一张单条腿的鸟

然后，这是随机的结果，无法复现，也就不能用来创作故事角色。

改变描述方式: 尝试用更抽象、更诗意的语言来描述毕方只有一条腿的特征，避免直接使用 “one leg” 或 “single leg” 等关键词，例如：
/imagine

Bifang, the firebird of legend, its form sculpted by celestial flames, stands as a beacon of power and mystery, its essence distilled into a single point of contact with the earth.

强调 “平衡” 和 “稳定”: 尝试强调毕方只有一条腿，但仍然能够保持平衡和稳定，例如：
/imagine

Bifang, the firebird of myth, defying the laws of nature, stands tall and proud on a single leg, its balance unwavering, its power emanating from its very core.

使用 “象征意义”: 尝试赋予毕方只有一条腿一些象征意义，例如：
/imagine

Bifang, the firebird of ancient lore, its single leg a symbol of its unwavering focus and determination, its fiery gaze fixed on the heavens, its power unmatched.

结合其他神话生物: 尝试将毕方与其他只有一条腿的神话生物进行比较或融合，例如：
/imagine

Bifang, a firebird with the single-legged grace of a Griffin, its wings ablaze, its gaze piercing, its presence commanding respect and awe.

不断地尝试和调整，最终还是没有办法 “欺骗” MJ ，生成一条腿的毕方形象。

还有什么办法可以让MJ生成一条腿的鸟呢？

欢迎大家提供思路。
