ComfyUI Extension: Primere nodes for ComfyUI

Primere nodes for ComfyUI Introduction

ComfyUI_Primere_Nodes is an extension designed to enhance the functionality of ComfyUI, a user interface for AI-based image generation. This extension provides a comprehensive set of nodes that streamline and automate various aspects of the image generation process, making it easier for AI artists to create high-quality images with minimal manual intervention. Whether you're working with Stable Diffusion (SD) or Stable Diffusion XL (SDXL) checkpoints, ComfyUI_Primere_Nodes offers a seamless experience by automatically adjusting settings based on the model version, allowing you to focus more on your creative process.

How Primere nodes for ComfyUI Works

ComfyUI_Primere_Nodes operates by integrating a series of specialized nodes into the ComfyUI workflow. These nodes handle everything from model selection and prompt organization to image refinement and metadata management. The extension automatically detects the type of checkpoint loaded (SD or SDXL) and adjusts the workflow accordingly. This means you don't have to manually switch nodes or settings when changing models. For example, if you switch from an SD checkpoint to an SDXL checkpoint, the extension will automatically adjust the resolution and other relevant settings to match the new model.

Primere nodes for ComfyUI Features

Model and Workflow Management

• Automatic Model Detection: Automatically detects if an SD or SDXL checkpoint is loaded and adjusts the workflow settings accordingly.
• One-Click Model Switching: Switch between different model concepts (e.g., Normal, LCM, Turbo, Cascade) with a single click.
• Customizable Prompts: Overwrite system settings directly from the prompt input, including model selection, subpath, and orientation.

Image Generation and Refinement

• Randomized Image Orientation: Randomize image orientation when using Comfy's batch queue mode.
• Auto-Save Features: Automatically save the final image along with workflow details in various formats (e.g., EXIF/PNGINFO).
• Custom Image Saver: Save images in different formats (jpg, png, webp) and resolutions directly from the image preview.

Prompt and Style Management

• Dynamic Prompts: Handle dynamic prompts and additional networks (Embedding, Lora, Lycoris, Hypernetwork) directly from prompts.
• Prompt Organizer: Organize prompts from .toml files and use them in dedicated nodes.
• Visual Loaders: Visual loaders for Checkpoints, Loras, Lycoris, Embedding, Hypernetworks, and .csv prompts.

Image Refinement

• Detailers and Refiners: Adjustable detailers for face, eye, hands, mouth, and fashion wear, with separate prompt inputs for better results.
• Segmented Refiners: Measure the aesthetic score of results and decide whether to apply changes based on the score.

Metadata and Recycling

• Image META/EXIF/PNGINFO Reader: Read and recycle metadata from older images, making it easier to reuse settings.
• Image Recycler: Read images without metadata and generate prompts from the picture using the Pic2Story model.

Primere nodes for ComfyUI Models

ComfyUI_Primere_Nodes supports various models, each tailored for specific tasks:

• SD and SDXL Checkpoints: Automatically adjust settings based on the loaded checkpoint.
• LCM, Turbo, Cascade, Playground, Hyper-SD, and Lightning: Different model concepts that can be switched with a single click.
• Long-CLIP: Supports long-text capability for prompts, improving the quality of generated images with detailed descriptions.

What's New with Primere nodes for ComfyUI

Recent Updates

• Hyper-SD Support: Added support for Hyper-SD with a one-click selector.
• Nvidia AlignYourSteps: Integrated support for Nvidia's AlignYourSteps sampler.
• Image Recycler Enhancements: Improved image recycler node to read images without metadata using the Pic2Story model.
• Segmented Refiners: Added segmented refiners that measure the aesthetic score of results and apply changes only if the score is better.
• Long-CLIP Integration: Implemented Long-CLIP for better handling of long and complex prompts.

Troubleshooting Primere nodes for ComfyUI

Common Issues and Solutions

1. Missing Python Libraries: If the node pack doesn't start, activate the Comfy virtual environment and run pip install -r requirements.txt.
2. Workflow Failures: If a workflow fails, try loading the Primere_minimal_workflow.json or Primere_basic_workflow.json from the 'Workflow' folder.
3. Node Changes: If nodes have changed after a git pull, use the 'Fix node (recreate)' menu option to update the nodes.
4. Missing Wildcard Files: Ensure that all custom wildcard files are copied to the 'wildcards' folder to avoid errors.

Frequently Asked Questions

• How do I switch between SD and SDXL models? Simply load the desired checkpoint, and the extension will automatically adjust the settings.
• Can I customize the prompts? Yes, you can overwrite system settings directly from the prompt input, including model selection, subpath, and orientation.
• How do I save images in different formats? Use the custom image saver on the image preview to save images in jpg, png, or webp formats.
