darkjunglemix_V2InkFix.safetensors
变分自编码器 VAE (Variational Auto Encoder)
作用:滤镜效果,增加饱和度之类的,类似美颜吧
安装路径:models/VAE
推荐:暂无,不咋用
Clip跳过层 (Contrastive Language Image Pre-training)
作用:就是 prompt 与生成图的关联性,数值越高关系越低,反之亦然
推荐:2-4

格式
基本
词组+短句,使用英文逗号分开,核心内容推荐使用 短句
比重
括号法则,麻烦,不用,哈哈哈
数字法则,写法简单
(xxxx: 1.5)= xxxx 权重= 1 x 1.5倍
(xxxx: 0.7)= xxxx 权重= 1 x 0.7倍
推荐:尽量保持在 0.5 - 1.6 之间
融合
AND

采样方法 (sampling method)
当前直接采用 DPM++ 2M Karras 就好了,其他大多过时了文章来源地址https://www.toymoban.com/news/detail-739663.html
参数介绍及设置
- 采样步数(Sampling steps): 调高的画,画得更精细。一般在 20-40 之间
- CFG Scale: 数值越高越贴近提示词,但是 AI 想象力就降低。一般在 7-12 之间
- denoising scale: 重绘幅度,越高的画,原画偏离度越大
- 随机种子:设定某个特定值时,风格就会和seed相似
