ComfyUI-Utils-extra

A compact collection of utility nodes for ComfyUI that I could not find in other node packs, but which I need in my production workflow.
They help automate repetitive tasks, relay group states, manage sampler parameters, and simplify work with lists.

This repository will be gradually expanded with new practical utilities.

Nodes Overview

---

Index Multiple

Category: utils/list
Class: IndexMultiple

Extracts a specific range from any List or Batch (images, masks, latents, text � any type) and creates individual outputs for that range.
Optionally replaces missing values with a fallback (if_none).

<details> <summary><b>Show detailed explanation & examples</b></summary> <img src="preview_index_multiple.jpg" width="100%"/>

How it works

1. Connect any List/Batch to input_any.
2. Set:
   • starting_index � the first index to output
   • length � how many elements to output
3. Outputs are generated as item_0 � item_49.
   Only the first length outputs are meaningful.

Example 1 � simple extraction

Input:
[mask_0, mask_1, mask_2, mask_3, mask_4]

Settings:

• starting_index = 3
• length = 2

Result:

• item_0 = mask_3
• item_1 = mask_4

Example 2 � unknown list length + fallback

If you ask for 5 outputs but receive only 2 items, the rest become None, or if_none if connected.

AKSampler Settings

Category: utils/settings
Class: AKSamplerSettings

A minimalistic node that stores three key sampler parameters:

• Seed
• Denoise
• Cfg

It outputs them as a LIST, suitable for passing into:

• AKSettings Out
• any SetNode
• custom controller graphs

AKSettings Out

Category: utils/settings
Class: AKSettingsOut

Expands the LIST received from AKSampler Settings into three independent outputs:

• Seed
• Denoise
• Cfg

Useful for distributing sampler parameters across multiple samplers or exposing them deeper into the graph.

IsOneOfGroupsActive

Category: utils/logic
Class: IsOneOfGroupsActive

Checks the state of all groups whose names contain a specified substring.
If at least one matching group is Active -> output is true.
If all matching groups are Muted/Bypassed -> output is false.

<details> <summary><b>More details</b></summary> <img src="preview_is_group_active.jpg" width="100%"/>

• Matching is substring-based.
  Example: "Face" matches FaceFix, FaceDetail, Faces, etc.
• If no matching groups are found -> output = false.

RepeatGroupState

Category: utils/logic
Class: RepeatGroupState

A connection-free interactive node that synchronizes the state of its own group with the state of other groups matching a given substring.

Logic:

1. Finds groups with names containing the target substring.
2. Checks whether any of them are Active.
3. If all matching groups are disabled -> it disables its own group.
4. If any matching group is active -> it enables its own group.

This allows groups to depend on other groups without wires, similar to rgthree repeaters.

<details> <img src="preview_repeater.jpg" width="100%"/> <summary><b>Usage examples</b></summary>

Example 1 � enable your group if �MainFix� is active

Filter: MainFix
If any "MainFix*" group is Active -> enable the current group.
