✨ sd_add_noise – 为 A1111 WebUI 添加后处理噪点效果的脚本
By MIAOKA
🐾 MiaoMiaoHarem Dogma 的完整生态终于实现。
🐾 The complete MiaoMiaoHarem Dogma ecosystem is finally here.
项目地址:sssyyyfff/sd_add_noise
🧠 简介 | Introduction
众所周知,Dogma 风格图像具有独特的颗粒感,这是其核心视觉特色之一。但在模型训练过程中加入稳定的噪点非常困难,稍有不慎还可能造成训练数据污染。
因此在我开始训练模型时,就思考是否能通过后处理方式来添加噪点。我调研了许多方案,发现只有 ComfyUI 有现成的插件节点,而A1111 WebUI 却缺乏类似的实现。
作为 A1111 的深度使用者,为了自己、也为了和我一样偏好 A1111 的朋友,我决定亲自开发这个脚本,为 MiaoMiaoHarem Dogma 补上生态中最后一块功能缺失。
It’s well known that Dogma-style artwork includes a signature noise/grain effect that enhances its unique aesthetic. However, adding stable noise during model training is difficult—and can easily corrupt your dataset.
So when I started building my Dogma model, I asked myself:
Why not add noise after image generation as a post-processing step?
After testing many approaches, I found that only ComfyUI offers noise plugins. But as a loyal user of A1111 WebUI, I wanted a native solution—both for myself and for other users like me.
This script is my answer, and now, the MiaoMiaoHarem Dogma ecosystem is truly complete.

📦 安装方法 | Installation
bash
复制编辑
git clone https://github.com/sssyyyfff/sd_add_noise.git
将 sd_add_noise
文件夹放入你的 A1111 WebUI 的 extensions/
目录下,然后重启 WebUI。
Place the sd_add_noise
folder inside your A1111 WebUI’s extensions/
directory and restart the WebUI.
⚙️ 使用说明 | Usage
打开 WebUI,进入
txt2img
或img2img
页面在脚本栏(Script)中选择
Add Noise After Generation
设置噪点强度(建议 15% 为细腻颗粒感,30% 为明显效果)
可勾选“生成对比图”查看前后差异
点击“生成”即可!
Open WebUI and go to
txt2img
orimg2img
In the script dropdown, choose
Add Noise After Generation
Set noise level (15% = fine grain, 30% = noticeable effect)
Enable "Show comparison image" if needed
Click
Generate
and done!
