Dynamic Sliders Stack for ComfyUI

A custom node pack for ComfyUI providing a stack of named sliders with dynamic behavior.

---

🚀 Features

• Slider Stacker: A node with a configurable number of named sliders (up to 50).

• Slider Receiver: Extracts the weight value of a specific slider from the stack output based on its index.

• Dynamic Max Strength: Adjusting the slider_max_strength scales all individual sliders proportionally.

  

• Dynamic Individual Sliders: Adjusting an individual slider_wt updates the slider_max_strength to reflect the new highest value among all sliders.

• String Output: Outputs a comma-separated string of the current weights for all active sliders.

• Dynamic UI: Automatically shows/hides slider input rows based on the slider_count setting.

• Context Menu: Right-click options for batch slider operations (Average, Reset, Set All to Max/Min).

📌 Nodes Overview

Slider Stacker

• Inputs:

  • slider_max_strength (FLOAT): The master maximum value. Adjusting this scales all sliders below it.
  • slider_count (INT): Controls how many slider rows are visible and processed (1-50).
  • slider_name_{i} (STRING): A text field to name or describe the slider (optional).
  • ({i}) (FLOAT Widget): The individual weight for this slider (0.0-2.0). Adjusting this updates the slider_max_strength if this slider becomes the new maximum.

• Output:

  • SLIDER_WEIGHTS (STRING): A comma-separated string of the weight values for sliders 1 through slider_count, formatted to two decimal places (e.g., "1.00, 0.50, 0.75").

• Right-Click Options:

  • Average Slider Values: Sets all visible sliders to their average value.
  • Reset Slider Values: Resets all visible sliders to the default value (1.0).
  • Set All to Max Value: Finds the highest value among visible sliders and sets all visible sliders to that value.
  • Set All to Min Value: Finds the lowest value among visible sliders and sets all visible sliders to that value.

Slider Receiver

• Inputs:

  • weights_string (STRING): Connect the SLIDER_WEIGHTS output from the Slider Stacker here.
  • index (INT): The 1-based index of the slider whose weight you want to extract (1-50).

• Output:

  • WEIGHT (FLOAT): The floating-point value of the slider at the specified index (returns 0.0 if the index is out of bounds or input is invalid).

💡 Use Case Scenarios

This node setup provides a centralized control panel for managing multiple numerical weights within your workflow. Here are a few examples:

• Multiple LoRA Weights: Assign each slider to a different LoRA. Use the Slider Stacker to adjust the overall impact (slider_max_strength) or fine-tune individual LoRA weights. Use Slider Receiver to retrieve specific weights.
• Prompt Segment Weighting: Control the emphasis of different parts of a prompt.
• Embedding/Textual Inversion Strength: Manage multiple embeddings by connecting Slider Receiver outputs to nodes that adjust their strength.
• Style/Character Consistency: Group controls for multiple elements (LoRAs, weights) onto one Slider Stacker for centralized adjustments.
• Controlling Custom Node Parameters: Control FLOAT inputs for strength, weight, etc., in custom nodes with Slider Receiver outputs.
• Centralized Control Panel: Use one or more Slider Stacker nodes to create a 'dashboard' for managing weights.
