ComfyUI-ImmacTools

Immac Tools

A small collection of ComfyUI extension nodes created for personal use.

Quick summary

• Package: ComfyUI-ImmacTools
• Purpose: ComfyUI extension providing utility nodes.

Installation

This repository is intended to be used as a ComfyUI custom node. Install it by one of the following methods:

A) ComfyUI Manager (When/If published)

• Use ComfyUI's built-in extension/manager (if available) to add this repo directly by URL. The manager will clone the repository into the appropriate custom_nodes folder and keep it updated.

B) Clone into your ComfyUI custom_nodes folder

1. From your ComfyUI repository root (or wherever you keep custom nodes), clone this repo into the custom_nodes directory:

# Example (from ComfyUI repo root)
git clone https://github.com/Immac/ComfyUI-ImmacTools custom_nodes/ComfyUI-ImmacTools

2. Restart ComfyUI. The extension's comfy_entrypoint should be discovered and the nodes will appear in the node list.

Immac Tools

A small collection of ComfyUI custom nodes created for personal use and convenience.

Quick summary

• Package: immac_tools
• Purpose: Utility nodes for ComfyUI (sigma schedule helpers and small helpers).

Installation

This repository is intended to be installed as a ComfyUI custom node. Two common installation methods:

1. Clone into your ComfyUI custom_nodes folder

From your ComfyUI repository root (or wherever you keep custom nodes), clone this repo into the custom_nodes directory:

# Example (from ComfyUI repo root)
git clone https://github.com/Immac/ComfyUI-ImmacTools custom_nodes/immac_tools

Then restart ComfyUI. The extension entrypoint should be discovered and the nodes will appear in the node list.

2. ComfyUI Manager (if available)

If you use a community manager/extension manager that supports installing extensions by Git URL, add this repo's URL and let the manager clone/update it for you.

• Node implementations: src/immac_tools/nodes.py and src/immac_tools/forwarding_nodes.py.
• Python package metadata: pyproject.toml and top-level package under src/immac_tools.

Nodes included

The main utility nodes included today are:

• Concatenate Sigmas Node

  • Class: ConcatenateSigmasImmacTools
  • Display name: Concatenate Sigmas Node
  • Inputs: sigmas_1, sigmas_2 (sigma schedules as tensors or lists)
  • Outputs: concatenated sigma schedule
  • Behavior: concatenates two sigma schedules, tolerating None inputs and non-torch objects by converting them to tensors.

• Splice Sigmas At %

  • Class: SpliceSigmasAtImmacTools
  • Display name: Splice Sigmas At %
  • Inputs: sigmas_a, sigmas_b, splice (float 0.0 - 1.0)
  • Outputs: spliced_sigmas (full), first_part, second_part
  • Behavior: picks a boundary on sigmas_a based on splice and combines sigmas_a and sigmas_b around that boundary. Accepts tensor or list inputs.

• Skip Every Nth Image

  • Class: SkipEveryNthImagesImmacTools
  • Display name: Skip Every Nth Image
  • Inputs: images (batch as list/tuple or torch tensor), n (int; n<=0 yields empty output)
  • Outputs: filtered images batch, indices removed
  • Behavior: drops every nth image while preserving the order of remaining items; returns the kept batch plus the zero-based indices that were removed.
