Wait For Passthrough

A utility node that waits for one input to be ready before passing through another input.

• Category: SGNodes/Utilities
• Inputs:
  • passthrough: Any type, lazy input that will be returned
  • wait_for: Any type, required input that triggers execution
• Output: The PASSTHROUGH output value
• Behavior: Executes when wait_for is ready, then requests the passthrough value if not already available

Wait For Milliseconds

Pauses execution for a specified number of milliseconds.

• Category: SGNodes/Utilities
• Inputs:
  • passthrough: Any type, lazy input that will be returned
  • milliseconds: Integer, number of milliseconds to wait (default: 1000)
• Output: The PASSTHROUGH output value

Select File From Directory

Allows selecting a file from a specified folder and its subdirectories with dynamic filtering.

• Category: SGNodes/Utilities
• Features:
  • Recursive Scanning: Automatically lists files from the folder and all its subdirectories.
  • Extension Filtering: Filter files by one or more comma-separated extensions (e.g., .png, .jpg).
  • Additional Filtering: Use "Contains" or "Regex" matches on top of the extension filter to narrow down the list.
  • Dynamic Updates: The file list updates automatically whenever the folder path, extensions, or filters are changed in the UI.
• Inputs:
  • folder_path: The absolute path to the directory to scan.
  • extensions: Comma-separated list of allowed extensions (default: empty searches all).
  • filter_type: Type of additional filtering (none, contains, regex).
  • filter_text: The text or regex pattern for the selected filter type.
  • file_name: The selected file from the dynamic dropdown list.
• Outputs:
  • FULL_PATH: The absolute path to the selected file.
  • RELATIVE_PATH: The path relative to the folder_path (includes subfolders).
  • FILE_NAME: Just the name of the file (no path).

Any Adapter

A universal adapter node that bypasses ComfyUI's strict type validation. It accepts any input type and provides an output of type "any" (*), allowing you to connect nodes with incompatible types (e.g., connecting a path string to a model loader's combo input).

• Category: SGNodes/Utilities
• Inputs:
  • value (Optional): * (IO.ANY). Connect any node output here.
• Outputs:
  • VALUE: * (IO.ANY). Connect this to any node input.
• Usage:
  1. Add Any Adapter.
  2. Connect your source node to the value.
  3. Right-click the destination node and select "Convert [parameter] to input".
  4. Connect VALUE to the newly created input.

Any Lazy Adapter

A variant of the Any Adapter that uses lazy evaluation. It only requests and processes the input data when it is actually needed by a downstream node. This is useful for optimizing complex workflows or handling conditional logic.

• Category: SGNodes/Utilities
• Inputs:
  • value (Optional): * (IO.ANY, Lazy). Connect any node output here.
• Outputs:
  • VALUE: * (IO.ANY). Connect this to any node input.

Is None

A utility node that checks if an input is None or not connected.

• Category: SGNodes/Utilities
• Inputs:
  • any_value (Optional): * (IO.ANY). Connect any node output here.
• Output:
  • IS_NONE: BOOLEAN. Returns True if the input is not connected or if it's connected and its value is None. Returns False otherwise.

None Primitive

A utility node that outputs an explicit None value.

• Category: SGNodes/Utilities
• Outputs:
  • NONE: * (IO.ANY). An explicit None value.

Call Remote URL

Performs a server-side HTTP request to a remote URL. Useful for integrating with external APIs.

• Category: SGNodes/Network
• Inputs:
  • url: Target URL string
  • method: HTTP method (GET, POST, etc.)
  • passthrough: Any type (IO.ANY), passed through to output. Useful for execution ordering.
  • body (Optional): Request body string
  • headers (Optional): JSON string of request headers
• Outputs:
  • PASSTHROUGH: The input passthrough value
  • STATUS_CODE: HTTP status code (INT)
  • RESPONSE_BODY: Response content (STRING)

Poll Remote URL

Polls a remote URL until a matching condition is met or maximum attempts are reached.

• Category: SGNodes/Network
• Inputs:
  • passthrough: Any type (IO.ANY), passed through to output.
  • url: Target URL string.
  • method: HTTP method (GET, POST, etc.).
  • match_type: Type of matching to perform (string, regex, json).
    • string: Checks if match_value is a substring of the response.
    • regex: Checks if match_value regex pattern matches the response.
    • json: Checks if match_value (as JSON) is a subset of the response JSON. Note: The match is partial but structural. To match {"status": "ok"} inside {"data": {"status": "ok"}}, your match value must include the full path: {"data": {"status": "ok"}}.
  • match_value: The value to match against.
  • invert_match: (Boolean) If True, waits until the match condition is FALSE (e.g. wait for something to disappear).
  • body (Optional): Request body string.
  • headers (Optional): JSON string of request headers.
  • max_attempts (Optional): Maximum number of polling attempts (default: 30).
  • delay_ms (Optional): Delay between attempts in milliseconds (default: 500).
• Outputs:
  • PASSTHROUGH: The input passthrough value.
  • STATUS_CODE: Last HTTP status code (INT).
  • RESPONSE_BODY: Last response content (STRING).

Map JSON To Property

Extracts a property from a JSON object string.

• Category: SGNodes/JSON
• Inputs:
  • json_string: JSON object string (e.g., {"a": 1}).
  • property_name: Name of the property to extract. Supports dot notation for nested keys (e.g., data.user.id).
• Output: JSON_PROPERTY: The value of the property as a string. If the value is an object or array, it returns a JSON string.

Map JSON Array

Maps a property from each object in a JSON array.

• Category: SGNodes/JSON
• Inputs:
  • json_array: JSON array string (e.g., [{"id": 1}, {"id": 2}]).
  • property_name: Name of the property to extract from each item. Supports dot notation (e.g., user.name).
• Output: JSON_ARRAY: A JSON array string of the extracted values (e.g., ["User1", "User2"]).

Find JSON Element

Finds the first element in a JSON array that matches a key-value pair.

• Category: SGNodes/JSON
• Inputs:
  • json_array: JSON array string.
  • match_key: The key to check in each element. Supports dot notation (e.g., status.code).
  • match_value: The value to match against (compared as string).
• Output: JSON_ELEMENT: The matching element as a JSON string. Returns empty string if not found.

Sound Player

Plays audio provided via the audio input when the node is executed. Acts as a passthrough for its main input.

• Category: SGNodes/Utilities
• Features:
  • Passthrough: Connect any type to passthrough and it will be passed to PASSTHROUGH output.
  • Volume Control: Adjust playback volume from 0 to 100.
  • Waveform Playback: Plays audio directly from the AUDIO stream (compatible with "Load Audio" nodes).
  • Client-Side Playback: The audio is synthesized and played in the browser when the ComfyUI server executes the node.
• Inputs:
  • passthrough: Any type (IO.ANY). The value to be passed through.
  • audio: The audio stream to play.
  • volume: Integer slider for volume control (0-100).
• Output:
  • PASSTHROUGH: The original passthrough value.

Sigmas Slice (Start/End)

Allows slicing a SIGMAS object using step indices, mimicking the behavior of the native KSampler (Advanced)'s start_at_step and end_at_step options.

• Category: SGNodes/Sigmas
• Inputs:
  • sigmas: The SIGMAS tensor to slice.
  • start_at_step: 0-indexed start position (Default: 0).
  • end_at_step: 0-indexed end position (Default: 10000).
  • return_with_leftover_noise: Boolean (Default: True). If False, the last sigma in the sliced range is set to 0.0, forcing a full denoise.
• Output:
  • SIGMAS: The sliced SIGMAS tensor.

Configuration

Create a config.json file in the same directory as this package to specify additional model folders to scan:

{
  "model_folders": [
    "C:\\Users\\YourUsername\\models",
    "D:\\AI\\LLM\\models",
    "/home/user/models"
  ]
}

The nodes will automatically scan:

• ComfyUI's text_encoders folder
• Any folders specified in config.json

Installation

1. Place this folder in your ComfyUI custom_nodes directory
2. Restart ComfyUI
3. The nodes will appear in the "SGNodes" category

Requirements

• ComfyUI
