Abominable Spaghetti Workflow

The unmatched prompt adherence of PixArt Sigma plus the perfect attention to detail of the SD 1.5 models, all in one ready-to-use workflow for ComfyUI.

Required Nodes

To use this workflow, you'll need to have ComfyUI_ExtraModels installed. Here's how to do it on Linux in four simple steps:

cd <your-comfyui-directory>
cd custom_nodes
git clone https://github.com/city96/ComfyUI_ExtraModels
pip install -r requirements.txt

Note 1: Running pip may require activating the virtual environment used to run ComfyUI.

Note 2: Windows users can refer to the installation methods suggested on the project GitHub Page.

Note 3: ComfyUI_ExtraModels has various dependencies and requirements on which it heavily relies. Therefore, it might be more convenient to install it using a node manager like ComfyUI Manager.

Required Files

You also need to have the following 6 files locally:

• From PixArt Sigma GitHub Page:

  • PixArt-Sigma-XL-2-1024-MS.pth

• From PixArt Text Encoder Hugging Face Repo:

  • config.json

  • model.safetensors.index.json

  • model-00001-of-00002.safetensors

  • model-00002-of-00002.safetensors

• From PixArt VAE Hugging Face Repo:

  • diffusion_pytorch_model.safetensors

Rename the file 'diffusion_pytorch_model.safetensors' to 'pixart_sigma_vae.safetensors'

Once obtained, place the files within the ComfyUI directory as outlined below:

• comfyui / models / checkpoints

  • PixArt-Sigma-XL-2-1024-MS.pth

  • Photon_v1.safetensor (or any other SD15 model)

• comfyui / models / t5

  • config.json

  • model.safetensors.index.json

  • model-00001-of-00002.safetensors

  • model-00002-of-00002.safetensors

• comfyui / models / vae

  • pixart_sigma_vae.safetensors
