Requirements:

- install missing custom nodes with "ComfyUI Manager" or running:

```
import os
import subprocess

custom_nodes=[
"https://github.com/ltdrdata/ComfyUI-Manager.git",
"https://github.com/kijai/ComfyUI-KJNodes",
"https://github.com/twri/sdxl_prompt_styler.git",
"https://github.com/Jcd1230/rembg-comfyui-node.git",
"https://github.com/BadCafeCode/masquerade-nodes-comfyui.git",
"https://github.com/Fannovel16/comfyui_controlnet_aux",
"https://github.com/Gourieff/comfyui-reactor-node"
]

os.chdir(os.path.expanduser('~/ComfyUI_/custom_nodes'))

for git in custom_nodes:
	subprocess.run(['git', 'clone', git])
```

- Reactor may fail to load. In that case, fix your env with:

```
pip3 uninstall -y opencv-python opencv-contrib-python opencv-python-headless
pip3 install opencv-python==4.7.0.72
```

- IPAdapeters models must be installed manually ( https://github.com/cubiq/ComfyUI_IPAdapter_plus ).

Usage:

Simply activate the group node you need to extend the basic pipeline.
