Environment

I tested the following environment, it might work on other environment, but I don't test:

Common

1. Windows 10/Ubuntu
2. GTX 3090
3. Cuda 12.1

Env 1 - see Method 1

1. ComfyUI embedded python (python 3.11) and ComfyUI Manager

Env 2 - see Method 2

1. conda
2. Python 3.11

Env 3 - see Method 3

1. conda
2. Python 3.11

Env 4 - see Method 4

1. Ubuntu
2. conda/Python 3.11
3. cuda 12.1

(Common) Installation - CUDA & cuDNN

This repo requires specific versions of CUDA and cuDNN to be installed locally:

• For CUDA, I only install and test CUDA 12.1, you can find it from https://developer.nvidia.com/cuda-12-1-0-download-archive
• For cuDNN, it MUST be v8.9.2 - CUDA 12.x (according to https://github.com/mdboom/pytoshop/issues/9), you can find it from https://developer.nvidia.com/rdp/cudnn-archive
• After install and unzip, make sure you configure the PATH of your system variable

(Common) Installation - Visual Studio Build Tools

It might also require Visual Studio Build Tools. However, I am not sure because my local already installed previously. If it needs, you can find from Visual Studio Build Tools.

(Method 1) Installation - ComfyUI Embedded Plugin & ComfyUI Manager

1. You could clone this repo inside comfyUI/custom_notes directly git clone https://github.com/jtydhr88/ComfyUI-LayerDivider.git
2. or use ComfyUI Manager
3. However, no matter which way you choose, it will fail at first time
4. Stop ComfyUI
5. Then go to custom_nodes\ComfyUI-LayerDivider, and run install_windows_portable_win_py311_cu121.bat

Done!

(If you prefer to use conda and python 3.10, you could follow the next)

(Method 2) Installation - ComfyUI

You could use conda to manage and create the ComfyUI runtime environment:

• use cmd/terminal to enter the comfyui root folder (which includes run_cpu.bat and run_nvidia_gpu.bat)
• conda create --name comfy-py-310 python=3.10
• conda activate comfy-py-310
• pip install torch torchvision --extra-index-url https://download.pytorch.org/whl/cu121
• pip install -r ComfyUI\requirements.txt

Then you can run python -s ComfyUI\main.py --windows-standalone-build to check ComfyUI running properly.

(Method 2) Installation - ComfyUI LayerDivider

Then we can clone and configure this repo for ComfyUI:

• cd ComfyUI\custom_nodes
• pip install onnxruntime-gpu --extra-index-url https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/onnxruntime-cuda-12/pypi/simple/
• pip install Cython
• pip install pytoshop -I --no-cache-dir
• pip install psd-tools --no-deps
• git clone https://github.com/jtydhr88/ComfyUI-LayerDivider.git
• cd ComfyUI-LayerDivider
• pip install -r requirements.txt

Congratulation! You complete all installation!

(Method 3) Installation - ComfyUI LayerDivider

Assume you already have a conda python3.11 env

• activate your env
• go into this folder and run install_conda_win_py311_cu121.bat

Congratulation! You complete all installation!

(Method 4) Ubuntu Installation - ComfyUI LayerDivider

Assume you already have a python3.11 env + cuda 12.1

• clone this repo inside custom_nodes folder
• cd ComfyUI-LayerDivider/
• pip install -r requirements.txt

Then make sure run them one by one:

• pip install cython
• pip install pytoshop -I --no-cache-dir
• pip install psd_tools
• pip install onnxruntime-gpu==1.17.0 --extra-index-url https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/onnxruntime-cuda-12/pypi/simple/

Congratulation! You complete all installation!

Node Introduction

Currently, this extension includes two modes with four custom nodes, plus two layer modes(normal and composite) for each mode:

Mode

There are two main layered segmentation modes:

• Color Base - Layers based on similar colors, with parameters:
  • loops
  • init_cluster
  • ciede_threshold
  • blur_size
• Segment Mask - First, the image is divided into segments using SAM - segment anything to generate corresponding masks, then layers are created based on these masks.
  • Load SAM Mask Generator, with parameters (These come from segment anything, please refer to here for more details):
  • pred_iou_thresh
  • stability_score_thresh
  • min_mask_region_area
  • LayerDivider - Segment Mask, with parameters:
  • area_th: determines the number of partitions. The smaller the value, the more partitions there will be; the larger the value, the fewer partitions there will be.

Layer Mode

Using in Divide Layer node to decide the layer mode:

• normal - Generates three layers for each region:
  • base - The base layer is the starting point for image processing
  • bright - The bright layer focuses on the brightest parts of the image, enhancing the brightness and gloss of these areas
  • shadow - The shadow layer deals with the darker parts of the image, emphasizing the details of shadows and dark areas.
• composite - Generates five layers for each region:
  • base - The base layer is the starting point of the image
  • screen - The screen layer simulates the effect of light overlay. It multiplies the color values of the image with the color values of the layer above it and then inverts the result, producing a brighter effect than the original image
  • multiply - The multiply layer simulates the effect of multiple images being overlaid. It directly multiplies the color values of the image with the color values of the layer above it, resulting in a darker effect than the original image.
  • subtract - The subtract layer subtracts the color values of the layer above from the base image, resulting in an image with lower color values.
  • addition - The addition layer adds the color values of the layer above to the base image, resulting in an image with higher color values.

Example workflows

Here are two workflows for reference:

• layerdivider-color-base.json
• layerdivider-seg-mask.json

Example outputs

• output_color_base_composite.psd
• output_color_base_normal.psd
• output_seg_mask_composite.psd
• output_seg_mask_normal.psd

Known issues

Sometimes, composite mode will fail on some images, such as ComfyUI example image, still under invesgating the cause
