ComfyUI Extension: Comfyui-LayerForge

Comfyui-LayerForge Introduction

Comfyui-LayerForge is an innovative extension designed to enhance your creative workflow within ComfyUI by providing a robust, layer-based editing experience similar to that of Photoshop. This extension allows you to work with multiple layers, apply masks, and use various blend modes, all within a single, integrated environment. Whether you're an AI artist looking to composite images, apply intricate masks, or perform precise transformations, Comfyui-LayerForge offers the tools you need to elevate your digital art projects. By integrating seamlessly with other nodes, it provides a comprehensive solution for complex image editing tasks, making it an essential tool for artists who want to push the boundaries of their creativity.

How Comfyui-LayerForge Works

At its core, Comfyui-LayerForge operates as a canvas node within ComfyUI, allowing you to manipulate images in a multi-layered environment. Imagine it as a digital workspace where each image or element you add becomes a separate layer that you can move, transform, and blend with others. This is akin to stacking transparent sheets on top of each other, where each sheet can be independently adjusted and then combined to create a cohesive final image. The extension uses a system of nodes to manage these layers, enabling you to apply transformations, masks, and blend modes with ease. This node-based approach allows for non-destructive editing, meaning you can experiment freely without permanently altering your original images.

Comfyui-LayerForge Features

• Freeform Inpainting Area: This feature allows you to draw custom shapes directly on the canvas for inpainting, similar to using a polygonal lasso tool. It generates content that blends seamlessly with the existing image, eliminating the need for a brush.
• Persistent & Stateful: Your work is automatically saved in the browser's IndexedDB, ensuring that your canvas state, including layers and their positions, is preserved even after a page reload.
• Multi-Layer Editing: You can add, arrange, and manage multiple image layers, each with its own z-ordering, allowing for complex compositions.
• Advanced Masking Tool: This tool provides a dedicated mode for creating masks with adjustable brush size, strength, and softness. Each mask has its own undo/redo history, giving you full control over your edits.
• Full Transformation Controls: Move, scale, and rotate layers with precision using either the mouse or keyboard shortcuts.
• Blend Modes & Opacity: Apply up to 12 common blend modes, such as Overlay and Multiply, and adjust the opacity of each layer individually through a context menu.
• Comprehensive Undo/Redo: Enjoy full history support for both layer manipulations and mask drawing, allowing you to backtrack and refine your work as needed.
• Seamless I/O: Easily import images by dragging and dropping files, copying and pasting from your clipboard, or importing the last generated image from your workflow with a single click.
• AI-Powered Matting: Use the optional BiRefNet model for background removal, providing a clean cutout of any layer.
• Efficient Memory Management: The extension includes an automatic garbage collection system to clean up unused image data, keeping your browser's storage footprint low.

Comfyui-LayerForge Models

Comfyui-LayerForge supports the BiRefNet model for AI-powered matting, which is used for automatic background removal. This model can be downloaded from Hugging Face or Google Drive and should be placed in the ComfyUI/models/BiRefNet/ directory. This feature is particularly useful when you need to isolate subjects from their backgrounds, allowing for more creative freedom in compositing.

Troubleshooting Comfyui-LayerForge

Common Issues and Solutions

• Black Output or Node Not Working: If you encounter a black output, it may be due to the node_id not being auto-filled. To resolve this, enable node ID display in ComfyUI settings and manually enter the correct node_id as shown above the node.
• Polygonal Lasso Tool Issues: If the polygonal lasso tool is not functioning as expected, ensure that the auto-refresh setting is enabled in LayerForge's settings. This ensures that new generation outputs update automatically in the canvas.

Frequently Asked Questions
