Required Files

To use the workflows, you need to have the following models installed in ComfyUI.<br/> Place them in the corresponding directories as specified below.

• <YOUR_COMFYUI_DIR> / models / checkpoints :
  • pixart_sigma-FP16.safetensors (1.2GB)
  • photon_refiner-FP16.safetensors (2.1GB)
• <YOUR_COMFYUI_DIR> / models / clip :
  • t5_xxl_encoder-FP8.safetensors (4.9GB)
• <YOUR_COMFYUI_DIR> / models / vae :
  • pixart_vae.safetensors (0.1GB)

Required Nodes

[!IMPORTANT] Ensure that your ComfyUI is updated to the latest version.

Additionally, the workflows require the following custom nodes to be installed:

• ComfyUI_ExtraModels: provides support for PixArt-Sigma.
• ComfyUI-Crystools: used for some simple string operations.

How to Automatically Install the Required Nodes

The easiest way to install the required nodes is by using ComfyUI-Manager. This extension for ComfyUI offers management functions to install, remove, disable, and enable custom nodes. It simplifies the process and can save you a lot of trouble.

If for some reason you cannot use ComfyUI-Manager, follow the instructions below to install the nodes manually.

Manually Installing Required Nodes on Linux

To manually install the nodes, open a terminal and run the following commands:

cd <your_comfyui_dir>
git clone https://github.com/city96/ComfyUI_ExtraModels ./custom_nodes/ComfyUI_ExtraModels
git clone https://github.com/crystian/ComfyUI-Crystools ./custom_nodes/ComfyUI-Crystools

If ComfyUI is using a virtual environment, you must activate it before installing the dependencies:

# You might need to replace '.venv' with the directory
# where the virtual environment is located
source .venv/bin/activate

Then, install the dependencies required by the nodes:

python -m pip install -r ./custom_nodes/ComfyUI_ExtraModels/requirements.txt
python -m pip install -r ./custom_nodes/ComfyUI-Crystools/requirements.txt

Manually Installing Required Nodes on Windows

If you are using the standalone ComfyUI release on Windows, open a CMD in the "ComfyUI_windows_portable" folder (the one containing your run_nvidia_gpu.bat file).

From that directory, run the following commands to install the required nodes:

git clone https://github.com/city96/ComfyUI_ExtraModels ComfyUI/custom_nodes/ComfyUI_ExtraModels
git clone https://github.com/crystian/ComfyUI-Crystools ComfyUI/custom_nodes/ComfyUI-Crystools

Then, install the dependencies required by these nodes:

.\python_embeded\python.exe -s -m pip install -r .\ComfyUI\custom_nodes\ComfyUI_ExtraModels\requirements.txt
.\python_embeded\python.exe -s -m pip install -r .\ComfyUI\custom_nodes\ComfyUI-Crystools\requirements.txt
