ComfyUI Extension: Mikey Nodes

Mikey Nodes Introduction

Welcome to mikey_nodes, a collection of custom nodes designed to enhance your experience with ComfyUI. This extension provides a variety of tools to help you create stunning AI-generated images with ease. Whether you're looking to add specific styles to your prompts, upscale images, or manage metadata, mikey_nodes has you covered. This extension is particularly useful for AI artists who want to streamline their workflow and achieve more control over their creative outputs.

How Mikey Nodes Works

At its core, mikey_nodes integrates seamlessly with ComfyUI to offer additional functionalities through custom nodes. These nodes act like building blocks that you can combine in various ways to achieve your desired results. Think of them as specialized tools in a digital art studio, each designed to perform a specific task, such as applying styles, resizing images, or adding metadata. By connecting these nodes in different configurations, you can create complex workflows that automate and enhance your image generation process.

Mikey Nodes Features

Prompt With Style

This feature allows you to add specific styles and LoRAs (Low-Rank Adaptations) to your prompts. You can use syntax like <lora:lora_name> or <lora:lora_name:0.8> to apply a LoRA with a specific weight. Styles can be added using <style:style_name>. Some built-in styles include:

• SAI-Enhance
• SAI-Anime
• SAI-Photographic
• SAI-Digital art
• SAI-Comic book
• SAI-Fantasy art
• SAI-Analog film
• SAI-Neonpunk
• SAI-Isometric
• SAI-Lowpoly
• SAI-Origami
• SAI-Line art
• SAI-Craft clay
• SAI-Cinematic
• SAI-3d-model
• SAI-pixel art
• SAI-Texture You can also add your own styles by creating a user_styles.json file in the root ComfyUI folder.

Wildcards

Wildcards allow for dynamic text generation in your prompts. Use the __word__ syntax to insert random words from a predefined list. You can also specify the number of lines or search for specific words within the wildcard file.

Image Size Ratios

You can define custom image size ratios by creating a user_ratios.json file. This allows you to specify the width and height for different image sizes, making it easier to maintain consistent aspect ratios.

Mikey Sampler and Mikey Sampler Base Only

These nodes simplify the image generation process by using a base -> refiner -> upscale workflow. The Base Only version skips a step in the middle, adding extra detail to the final image. You can customize settings like upscale_by and highres_strength to control the final output.

Mikey Sampler Tiled and Mikey Sampler Tiled Base Only

These samplers use a tiled approach to enhance image details after upscaling. This method helps in achieving higher quality images by focusing on smaller sections of the image.

Style Conditioner

This node allows you to blend styles into your image by averaging the conditioner passed through the node. You can control the strength of the style application to achieve the desired effect.

Empty Latent Ratio Select SDXL and Custom SDXL

These nodes let you select or define custom aspect ratios for your images, ensuring they fit within a 1024x1024 resolution.

Preset Ratio Selector and Ratio Advanced

These nodes offer advanced options for selecting and customizing image ratios. You can create presets or manually enter dimensions to fit your specific needs.

Resize Image for SDXL and Batch Resize Image for SDXL

These nodes allow you to resize single images or batches of images to fit within a 1024x1024 resolution, making them ideal for Img2Img workflows.

Save Image With Prompt Data

This node saves images with the prompt data embedded in the filename and metadata, making it easier to track and reproduce specific results.

Upscale Tile Calculator

This node helps calculate tile sizes for the Ultimate SD Upscaler, ensuring even tiling and avoiding artifacts.

Wildcard Processor

This node builds strings using your wildcard files, allowing for more dynamic and varied prompts.

Add Metadata and Save Metadata

These nodes let you add and save custom metadata to your images, providing additional context and information for each generated image.

HaldCLUT

This node applies a HaldCLUT to an image, changing its colors to imitate the look of different films or filters. You can find additional HaldCLUT files at rawtherapee.com (http://rawtherapee.com/shared/HaldCLUT.zip).

Image Caption

This node adds a caption bar to the bottom of your image, useful for adding prompts or checkpoint names. You can customize the font by placing TTF files in a fonts folder in the base directory of ComfyUI.

Seed String, Int to String, and Float to String

These nodes help in converting and managing different data types, making it easier to integrate various elements into your workflow.

Troubleshooting Mikey Nodes

Common Issues and Solutions

1. Node Not Found: Ensure that you have cloned the mikey_nodes repository into the correct directory (ComfyUI/custom_nodes/).
2. Styles Not Applying: Check the syntax in your prompt and ensure that the style or LoRA name is correct.
3. Image Resizing Issues: Verify that your user_ratios.json file is correctly formatted and placed in the root ComfyUI folder.
4. Metadata Not Saving: Make sure you have connected the Add Metadata and Save Metadata nodes correctly in your workflow.
