ComfyUI Extension: ComfyUI-LMCQ

ComfyUI-LMCQ Introduction

ComfyUI-LMCQ is an extension designed to enhance the functionality of the ComfyUI ecosystem by providing a set of versatile and practical nodes. These nodes are intended to streamline workflows and improve the security of models and data within the ComfyUI environment. The name "LMCQ" is an abbreviation of the team behind this extension. This toolset is particularly beneficial for AI artists who want to protect their creative assets and manage their workflow more efficiently.

How ComfyUI-LMCQ Works

At its core, ComfyUI-LMCQ operates by integrating additional nodes into the ComfyUI framework. These nodes offer enhanced capabilities such as image processing, model encryption, and workflow protection. By using these nodes, you can apply watermarks to images, encrypt models to prevent unauthorized access, and secure your workflows against tampering. The extension leverages advanced encryption techniques to ensure that your data remains safe and secure across different platforms.

ComfyUI-LMCQ Features

Image Processing Nodes

• LmcqImageSaver: This node allows you to add watermarks to your images and decide whether to save metadata. You can customize the watermark text, size, and position, as well as adjust the image's brightness and contrast.
• LmcqImageSaverTransit: Similar to LmcqImageSaver, but with the added ability to pass the processed image to the next node in the workflow.
• LmcqImageSaverWeb: Extends LmcqImageSaver by enabling the automatic sending of files and prompt IDs to a specified API endpoint, reducing the need for persistent connections.

Model and Workflow Security

• LmcqModelEncryption & LmcqModelDecryption: Encrypt and decrypt models using a custom key. This ensures that your models are protected and can only be accessed by authorized users.
• LmcqWorkflowEncryption & LmcqWorkflowDecryption: Secure your workflow files by encrypting them with a password. This prevents unauthorized access and ensures that only those with the correct password can use the workflow.

Runtime Protection

• LmcqRuntimeModelEncryption & LmcqRuntimeModelDecryption: Provides real-time encryption and decryption of models, allowing them to be used only on authorized machines.
• LmcqRuntimeWorkflowEncryption & LmcqRuntimeWorkflowDecryption: Protects workflows with machine-specific authorization, ensuring they can only be decrypted and used on designated devices.

ComfyUI-LMCQ Models

The extension does not introduce new models but rather provides tools to manage and secure existing models within the ComfyUI framework. By using the encryption and decryption nodes, you can ensure that your models are only accessible to those with the correct credentials, thereby safeguarding your intellectual property.

• 2024-12-12: Implemented model encryption capabilities, providing robust protection for your models. These updates focus on improving security and usability, ensuring that AI artists can work in a safe and efficient environment.

Troubleshooting ComfyUI-LMCQ

Common Issues and Solutions

• Problem: Unable to decrypt a model or workflow.
• Solution: Ensure that you are using the correct decryption key and that both the encrypted file and its associated .meta file are in the same directory.
• Problem: Watermark not appearing on images.
• Solution: Check the watermark settings, including text, size, and position. Ensure that the watermark feature is enabled.

Frequently Asked Questions

• Q: Can I use the encrypted models on any machine?
• A: No, encrypted models are designed to be used only on authorized machines to enhance security.
• Q: How do I share an encrypted workflow with others?
• A: Share the encrypted workflow file along with the decryption password. The recipient will need to use the decryption node to access the workflow.
