ComfyUI Extension: ComfyUI-CRZnodes

ComfyUI-CRZnodes Introduction

ComfyUI-CRZnodes is an extension designed to enhance the functionality of ComfyUI by providing a set of custom nodes that streamline and simplify the workflow for AI artists. This extension offers a variety of nodes that can be used to create more dynamic and interactive user interfaces within ComfyUI, making it easier to manage and manipulate data. Whether you're looking to create more intuitive dashboards or need specific nodes for data comparison and execution control, ComfyUI-CRZnodes provides the tools to do so efficiently.

How ComfyUI-CRZnodes Works

At its core, ComfyUI-CRZnodes works by adding a collection of nodes to ComfyUI that can be used to build more complex and interactive workflows. These nodes act as building blocks that you can connect and configure to perform specific tasks. For example, you can use sliders to adjust values dynamically, dropdowns to select options, or switches to control the flow of data. The extension simplifies the process of creating user interfaces by providing pre-built components that can be easily customized to fit your needs.

Dashboard Nodes

• Boolean Toggle: A simple switch to toggle between true and false states.
• Float Slider & Integer Slider: Allows you to adjust numerical values with precision. You can set minimum, maximum, and step values by double-clicking the slider.
• Dropdown & Custom Dropdown: Provides a list of options to choose from. Custom dropdowns can be configured with user-defined items.
• Map Custom Dropdown: Automatically detects custom dropdown choices and passes through the selected data.
• Image Selector: Enables selection of images from a predefined list.
• Dashboard Node (Experimental): A versatile node that adapts to its connections, intended to replace individual dashboard nodes in the future.
