AI绘画|Stable Diffusion实战——如何稳定绘制全身图（咒语）？

#首发创作赛#

众所周知，使用Stable Diffusion进行绘制全身图时，总是会脸崩。今天就分享一下来自模型geminixMix_V3大佬的干货，如何能稳定的绘制全身图。

提醒：不可说原因，部分配图已删除，请自行生图O(∩_∩)O

1.本文中使用geminixMix_V3模型在SD1.5的环境下生成,CKPT下载处放在最后.

2.贴上准备好的prompt,下面是已经帮大家分段好的提示词,

>>第一段是定义画面和图片品质

>>第二段式形容角色

>>第三段式定义环境场景

大家可以依照自己的需求做出调整，最好可以把从头到脚的配件都写进去Prompt,可以确保万无一失,尤其是鞋子.

3.参数设定:

Sampler: DPM++ SDE Karras,

Sampling Steps: 30,

尺寸: 576X1024,

CFG scale: 7,

种子:自定义或 -1,

Hires.fix打勾V,

放大算法: 个人最常用 Lanczos 可以多方尝试其他算法看效果

>>Hires steps: 0

>>Denoising: 0.3

>>Upscale by(放大倍数): 2.0

4.LoRA:

本分享使用2个LoRA：

>>GeminiX_201_NightPunkV1 权重 0.15

>>GeminiX_033_SofiaV1 权重 0.35

5.生成

按下生成后依照显卡等级(3080约200秒),就会生成一个全身靓妹图,prompt中的 full-body: 权重建议设定 1.4~1.5,这样才有大机率生成全身的人体下,还能LoRA保留角色脸部特整,这里附上 0.5/1.0/1.5/2.0 几种权重的差异.(2.0时LoRA脸部特征已经有点跑掉了)

6.设定细项解释

这个尺寸576X1024加上 2X 的Hires.fix,以及 full-body:1.4 的prompt,在全身的构图且无须其他插件下,让脸部可以清晰生成,并且LoRA特征不会跑掉.

7.下面是Prompt:

Prompt:

(photorealistic:1.4), (extremely intricate:1.2),(exquisitely detailed skin), cinematic light, ultra high res, 8k uhd, intricate details, Movie Light, film grain, dreamlike, perfect anatomy, best shadow, delicate, RAW, realistic, ((SFW:1.9)), ((school life)),

.Negative prompt:

(worst quality, normal quality, low quality:1.7), paintings, sketches, freckles, lowres, monochrome, grayscale, bad proportions, watermark, signature, text, curvy, plump, fat, muscular female, NSFW:2.0,

8.其他:

>>LoRA是使用geminixMix_V3训练的

>>其他的配图都会附上prompt.
