在学习 AI 绘画这段时间,发现 AI 绘画并不会完全替代设计师,而是可以让出图质量更好,效率更高。比如上面是用 midjourney 生成线稿,PS 稍微做一些修正,再用controlnet 控制, stable diffusion上色,多套 AI 组合券,可以快速生成效果惊艳的图。作者:三思
先欣赏下作品






1、线稿产出
mj关键词:Black and white line drawing illustration of a cute cat cartoon IP character, black line sketch, wearing a fortune hat, wearing a collar around the neck, Carrying a huge bag containing scrolls and ingots, matching rope and straps at his wrists, Chinese element style, popular toys, blind box toys,Disney style, white background --niji 5 --style expressive

2、ps手动手动重绘错误的地方

有些图出来没有阴影容易飘,可以自己画一个出来

3、SD上色
关键词
正关键词主要前面添加了增加照片质感常用的+mj生成线稿的关键词调整(去掉mj里线稿的关键词,一开始嘴巴效果不好,添加了张开嘴巴等关键词,颜色都是可以单独调整控制)+风格参数
负关键词看自己的效果添加。添加一切你不想要的东西,我前面调用了词嵌入(bad_prompt_version2-neg, badhandv4, easynegative)需要去c站下载,这些主要是为了控制人手部错误的,在最后一步放大的时候,却起到了反作用,强行给小猫咪小动物5个手指(建议不加,或者建议生成的时候加,放大的时候去掉)
正关键词
((white background)), (8k, raw photo, best quality, masterpiece),(photon mapping, radiosity, physically-based rendering, automatic white balance),CG, unity, official art, amazing, finely detail, an extremely delicate and beautiful, extremely detailed,3d,rendering, c4d, blender, octane render,
Chinese festive color scheme, open mouth, 1 tooth, The cat has a pair of white gloves,
a cute cat cartoon IP character, black line sketch, wearing a hat, wearing a collar around the neck, carrying a huge red bag, matching rope and straps at his wrists,Chinese element style,
poular toys, blind box toys,Disney style,
负关键词:back and white,green,blue,purple,
真实系大模型:revAnimated v1.2.2版本
尺寸最好和你的草稿图保持一致(前面的步骤没有截图,这里重新做了一张)如果尺寸太大爆显存可以保持和草图一样的比例缩小尺寸

最重要的ControlNet设置
上传自己的草图到ControlNet,点击启用。记得点💥的图标让预处理器生效

4、放大高清尺寸
Multi Diffusion + Tiled VAE + ControlNet Tile模型
将生成的图片发送到图生图,会把关键词种子一并发送过去
重绘幅度建议0.3-0.75 太高图片细节发生变化,产生多个猫头
放大的时候不要在提示语中添加任何具体对象,只需添加提高质量之类的提示词





5、完成(也可以PS修改下不满意的地方)
截图了一部分生成的图,百里挑一
