ComfyUI-hybs-nodes

Various custom nodes will be added.

Nodes

Resolution Selector

Provides a manual resolution selection node via a dropdown menu. Allows manual selection of a resolution from a dropdown menu populated from config/resolution_combos.json (or the default list).

• Category: HYBS/ResolutionSelector

• Inputs:

  • resolution (Combo dropdown): A string in the format "<width>x<height>".

• Outputs:

  • width (INT)
  • height (INT)

• Behavior:

  1. On startup, loads options from config/resolution_combos.json; if missing or invalid, falls back to default list.
  2. Populates the dropdown with "WxH" strings for each pair.
  3. Throws a runtime error if an unexpected format is selected.

Random Resolution Selector

Provides a dynamic resolution selection node based on a seed input.

Outputs a resolution (width, height) from a predefined list based on a seed input. It reloads config/resolution_combos.json on each execution, so changes to the JSON file take immediate effect.

• Category: HYBS/ResolutionSelector

• Inputs:

  • seed (INT): The seed value; same seed always yields the same resolution.

• Outputs:

  • width (INT)
  • height (INT)

• Behavior:

  1. On each node execution, attempts to load config/resolution_combos.json; if missing, uses the default hardcoded list.
  2. Throws a runtime error if the JSON file exists but is malformed or has invalid format.
  3. Determines the index with seed % len(combos) to select the resolution.

Configuration

Place your custom resolution list in config/resolution_combos.json at the root of the extension (next to nodes/). The file must contain a non-empty JSON array of integer pairs, e.g.:

[
  [1024, 1024],
  [1088, 1088],
  [1152, 1152],
  [896, 1152],
  [832, 1216]
]

• If the file is missing, a built-in default list (1024–2048 squares and representative portrait/landscape) is used.
• If the file is present but invalid (empty array or incorrect format), the node will throw a value error.

Installation

1. Clone this repository into your ComfyUI custom_nodes/ folder:

   cd path/to/ComfyUI/extensions
   git clone https://github.com/hybskgks28275/ComfyUI-hybs-nodes.git
   

2. Ensure the directory structure:

   └── custom_nodes/
       └── ComfyUI-hybs-nodes/
           ├── config/
           │   └── resolution_combos.json.example
           ├── nodes/
           │   └── hybs_resolution_selector.py
