ComfyUI Extension: ControlAltAI Nodes

ControlAltAI-Nodes Introduction

ControlAltAI-Nodes is a collection of custom nodes designed to enhance the ComfyUI framework, focusing on improving the quality of life for AI artists. These nodes are crafted to simplify and streamline various tasks, making your creative process more efficient and enjoyable. Whether you're looking to optimize image resolution, apply advanced sampling techniques, or manage complex workflows, ControlAltAI-Nodes offers tools that can help you achieve your artistic goals with ease.

How ControlAltAI-Nodes Works

At its core, ControlAltAI-Nodes operates by integrating seamlessly with the ComfyUI framework, providing additional functionality through specialized nodes. Think of these nodes as building blocks that you can connect to create a customized workflow tailored to your specific needs. Each node performs a unique function, such as calculating optimal image resolutions or blending noise into images, allowing you to focus on the creative aspects of your work without getting bogged down by technical details.

ControlAltAI-Nodes Features

Flux Resolution Calculator

This feature helps you determine the best image resolution for your projects using the Flux model. Instead of relying on standard resolutions, you can specify the desired megapixel count and aspect ratio. The calculator then provides the exact dimensions needed, ensuring your images are of the highest quality and tailored to your specifications.

• Supported Megapixels: 0.1 MP to 2.5 MP
• Custom Ratio: You can enable or disable custom ratios to fit your unique requirements.

Flux Sampler

The Flux Sampler node combines multiple functionalities into one, making it easier to manage your sampling processes. It supports only positive conditioning and is compatible with specific samplers and schedulers designed for the Flux model.

• CFG Setting: Fixed at 1
• Latent Compatibility: Requires SD3 Empty Latent Image

Flux Union ControlNet Apply

This node allows you to combine two ControlNet Union units effectively, enhancing your image processing capabilities. It's particularly useful for tasks like photo restoration and upscaling game assets.

• Recommended Settings: Strength between 0.15-0.65, end percentage between 0.200-0.900
• PreProcessors: Includes options like Canny Edge and Depth Anything V2 Relative

Get Image Size & Ratio

This node provides the resolution and aspect ratio of an image, which can be used in conjunction with the Flux Resolution Calculator for precise adjustments.

Integer Setting

This node outputs a raw value of 1 or 2, allowing you to control logical flows in your workflow. It's useful for setting up two-way switches.

Choose Upscale Model

A simple node that uses boolean logic to select between two upscale models based on a true or false response.

Noise Plus Blend

This node generates Gaussian blur noise and blends it into your image, helping to maintain texture details during upscaling.

• Settings: Noise scale between 0.30-0.50, blend opacity between 10-25

ControlAltAI-Nodes Models

ControlAltAI-Nodes supports the Flux model series, including Flux1.[dev] and Flux1.[schnell], developed by Black Forest Labs. These models are designed to push the boundaries of image generation, offering advanced capabilities for creating high-quality images.

Troubleshooting ControlAltAI-Nodes

If you encounter issues while using ControlAltAI-Nodes, here are some common problems and solutions:

• Blurry Images at High Resolutions: If images appear blurry above 1 MP, try adjusting the megapixel settings or using a different aspect ratio.
• Incompatible Latent Images: Ensure you're using the SD3 Empty Latent Image with the Flux Sampler node.
• Artifacts in Upscaled Images: Adjust the noise scale and blend opacity settings in the Noise Plus Blend node to reduce artifacts.
