2.安装模型
AI绘画软件Stable Diffusion模型/Lora/VAE文件存放位置
3.运行
开始本地运行吧,浏览器打开http://127.0.0.1:7860,显示如下,可以看到模型也加载了,运行成功。
4.找到关键词,粘贴到提示词中
找tag关键词网站:https://tag.redsex.cc
复制关键词到箭头1的位置,点击自动按钮就会自动设置模型和参数了。
以下为高级技巧
一:参数介绍:
标准参数设置,sampler(采样方法):Euler a(k_euler_ancestral),迭代次数28,CFG:11。
设置更改:
Stop At last layers of CLIP model 改为 2
eta(noise multiplier) for ancestral samplers 改为 0.68
Eta noise seed delta 设为 31337
显存10G以下推荐勾选训练栏下的Move VAE and CLIP以节省显存。
取消勾选deepbooru按字母顺序排序
Euler(euler_ancestral)比Euler a迭代慢,增加迭代次数可达到Euler a效果。
迭代步数增加不能解决人物手脚异常增多的问题。
人脸修复没啥用,有人还会出bug,不要开。
高分辨率修复会改变画面内容,据说加了1girl权重再修复可以解决出现多人的问题。
图片大小 :人像肖像 512x768,风景画 768×512,可按比例加大或减小。生成的画面内容对图片大小也敏感,所以一般按着比例来比较靠谱。
使用小tips:
1. DDIM 与 Euler 适合长迭代下产生细节较好的图片,而Euler a属于短迭代与较好效果的常用折中选择。较新的sampler DPM++2S A 也有较好的效果。
2. 记得设置在图片中保存信息。
3. 出图结果为黑色一般是因为显存不足,把出图大小减小。
4. 显卡不行的情况下,想一次出多图,可以选择加大batch count,这样每一个batch结束都会保存出图。加batch size会因为集中生成图片爆显存,然后颗粒无收。
5. 想要高清细节大图,单单加迭代步数和加大图片有上限,且产出慢,大图需高显存。一般策略是中等出图,再导入到后处理界面,使用ESRGAN_4x放大器,再把GFPGAN可见度拉满。可适当调节参数或者换放大器试着玩玩。
二、AI绘画关键词
找tag关键词网站:https://tag.redsex.cc
1. 关键词构成结构
version 1:(使用Stable Diffusion时,不用写画面尺寸,此处为参考补充)
version 2:
1. 通用Tag起手式:
正向:
masterpiece, best quality, 更多画质词,画面描述
反向:
nsfw, lowres, bad anatomy, bad hands, text, error, missing fingers,extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurry,根据画面产出加不想出现的画面。nsfw(not safe for work=涩图)
2. 越靠前的Tag权重越大;比如景色Tag在前,人物就会小,相反的人物会变大或半身。
3. 生成图片的大小会影响Prompt的效果,图片越大需要的Prompt越多,不然Prompt会相互污染。
4. 在Stable Diffusion 中使用()英文括号可增加括号中Tag在画面中的权重 x1.1,[]可减小Tag权重x0.91。在NovelAi官网中,使用{}增加权重x1.05。
5. Prompt支持使用emoji,且表现力较好,可通过添加emoji达到表现效果。如😍形容表情,🖐可修手。
6.“+” , “ AND” , “|” 用法:
“+”和“ AND ”都是用于连接短Tag,但AND两端要加空格。"+"约等于" and "
“|” 为循环绘制符号(融合符号)
(Prompt A: w1)|(Prompt B: w2)
以上表达适用于WebUI,w1、w2为权重。AI会对A、 B两Prompt进行循环绘制。可往后无限加入Prompt。
下面通过发色来测试:
(red hair:1.1)+(yellow hair:1.25)+(green hair:1.4)
(red hair:1.1)+(yellow hair:1.25)+(green hair:1.6)
(red hair:1.3)+(yellow hair:1.25)+(green hair:1.4)
固定SEED的简单彩发测试:
从左到右依次为
(red hair:1.2)+(yellow hair:1.4)+(green hair:1.4)
(red hair:1.2) AND (yellow hair:1.4) AND (green hair:1.4)
(red hair:1.2),(yellow hair:1.4),(green hair:1.4)
(red hair:1.2)_(yellow hair:1.4)_(green hair:1.4)
(red hair:1.2)|(yellow hair:1.4)|(green hair:1.4)
(red hair:1.2)(yellow hair:1.4)(green hair:1.4)
(red hair:1.2) (yellow hair:1.4) (green hair:1.4) Tag中间只夹空格效果也还不错
结论:
① (Prompt A) AND (Prompt B),DDIM采样器不支持且测试效果不太好,暂不推荐使用
② 目前来看,+号约等于“ and ”,其他用法也都可以尝试效果差不多。
7. 权重赋予
(Prompt A:1.5,Prompt B:1.5) 效果并不好,不如直接(Prompt A:1.5),(Prompt B:1.5),彩发可以直接(red hair:1.2),(yellow hair:1.4),(green hair:1.4)
8. 分布渲染
句式:
[Prompt A:Prompt B:Step]
[Prompt A::Step]
[:Prompt B:Step]
此处Step > 1时表示该组合在前多少步时做为Prompt A渲染,之后作为Prompt B渲染。Step < 1时表示迭代步数百分比。
Prompt格式优化:
1. 简易换行三段式表达:
第一段: 画质tag,画风tag
第二段:画面主体,主体强调,主体细节概括。(主体可以是人、事、物、景)画面核心内容
第三段:画面场景细节,或人物细节,embedding tag。画面细节内容
第二段一般提供人数,人物主要特征,主要动作(一般置于人物之前),物体主要特征,主景或景色框架等
2.元素同典调整版语法:
质量词→前置画风→前置镜头效果→前置光照效果→(带描述的人或物AND人或物的次要描述AND镜头效果和光照)*系数→全局光照效果→全局镜头效果→画风滤镜(embedding)
Tips: 不同模型(ckpt)对Prompt的敏感程度不同,一套完善的prompt在不同的模型中,表达效果会有差异。每个模型都有自己的特色,需根据模型特色,慢慢调试prompt组合。
