# 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**: The `Slider Stacker` outputs a comma-separated string of the current weights for all active sliders.
|
|
* **Dynamic UI**: The stacker node 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
|
|
|
|
### 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. (Widget name uses parentheses around the index).
|
|
* **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`: Sets 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 index is out of bounds or input is invalid).
|
|
|
|
## Installation
|
|
|
|
1. Ensure the folder containing these files is named `Dynamic_sliders_stack`.
|
|
2. Place the `Dynamic_sliders_stack` folder inside your ComfyUI `custom_nodes` directory.
|
|
3. Restart ComfyUI.
|
|
|
|
## Usage Example
|
|
|
|
1. Add a `Slider Stacker` node (found under the `Dynamic Sliders Stack` category).
|
|
2. Set the `slider_count`.
|
|
3. Adjust sliders or use right-click options.
|
|
4. Add a `Slider Receiver` node.
|
|
5. Connect `SLIDER_WEIGHTS` to `weights_string`.
|
|
6. Set the `index` on the Receiver.
|
|
7. Connect the `WEIGHT` output.
|
|
|
|
## 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` nodes to pipe the individual weights into the `strength_model` and/or `strength_clip` inputs of `LoRA Loader` nodes.
|
|
* **Prompt Segment Weighting:** If using nodes that allow weighting different parts of a prompt (e.g., via attention syntax or specialized nodes), you could use sliders to control the emphasis on different elements like `(subject:WEIGHT)`, `(style:WEIGHT)`, `(background:WEIGHT)`. Connect `Slider Receiver` outputs to the relevant weight inputs.
|
|
* **Embedding/Textual Inversion Strength:** Control the influence of multiple embeddings by connecting `Slider Receiver` outputs to nodes that adjust their strength (if available).
|
|
* **Style/Character Consistency:** If you have multiple elements defining a style or character (multiple LoRAs, specific prompt weights), group their controls onto one `Slider Stacker` for easier holistic adjustments.
|
|
* **Controlling Custom Node Parameters:** Any custom node that accepts a FLOAT input for strength, influence, weight, etc., can potentially be controlled by connecting a `Slider Receiver`'s output to it.
|
|
* **Centralized Control Panel:** Create a 'dashboard' near the start of your workflow using one or more `Slider Stacker` nodes to manage key weights without needing to hunt down individual nodes later in the graph.
