ComfyUI Extension: ComfyUI-ReLight

comfyui-relight Introduction

Welcome to comfyui-relight, an innovative extension designed to transform your images with stunning cinematic lighting effects, all with just a single click. This powerful tool is a custom node for ComfyUI, offering professional-grade lighting capabilities that can dramatically enhance your artwork. Whether you're looking to create dramatic shadows, simulate natural window lighting, or add a warm sunset glow, comfyui-relight provides precise control over every aspect of your lighting setup. This extension is perfect for AI artists who want to elevate their images with sophisticated lighting effects without needing extensive technical knowledge.

How comfyui-relight Works

At its core, comfyui-relight works by simulating various lighting conditions and effects on your images. Think of it as a virtual lighting studio where you can place up to three independent light sources anywhere in your image. These light sources can be adjusted in terms of color, intensity, and position, allowing you to create a wide range of lighting scenarios. The extension uses advanced algorithms to simulate how light interacts with different parts of your image, including the subject and background, to produce realistic and visually appealing results. By using masks, you can control which parts of the image are affected by the lighting, giving you even more creative freedom.

comfyui-relight Features

Powerful Lighting Control

• Multiple Light Sources: You can place up to three light sources in your image, each with its own settings.
• Dynamic Lighting Modes: Choose from colored lights with adjustable RGB values or apply color correction to tweak brightness, contrast, saturation, temperature, tint, and gamma.
• Flexible Mask Shapes: Use circular falloff for natural radial lighting or gradient mode for directional effects like sunset rays.

Advanced 3D Lighting Simulation

• Subject Interaction: When using a mask, you can simulate different lighting interactions such as front lighting, rim lighting, or standard lighting without subject occlusion.

Production-Ready Features

• Presets: Instantly apply professional lighting setups like "Soft Window Light" or "Warm Sunset Glow."
• Visual Debugging: See exactly where your lights are positioned and how they interact with your image.
• Fine-Tuning Controls: Adjust blur, strength, and rim amplification for perfect lighting effects.

comfyui-relight Models

Currently, comfyui-relight does not have different models. Instead, it offers a variety of presets and customizable settings that allow you to achieve different lighting effects. These presets serve as starting points, which you can further tweak to suit your artistic vision.

Troubleshooting comfyui-relight

Here are some common issues you might encounter while using comfyui-relight, along with solutions:

• No visible effect: Increase the effect strength or light intensity.
• Light too strong: Decrease the effect strength or specific intensity/brightness values.
• Occlusion not working: Ensure that 3D lighting is enabled and a mask is connected.
• Black debug image: Check the ComfyUI console for errors.
• Node fails to load: Ensure that the required dependencies, like scipy, are installed.
• Poor mask quality: Use the RemBG feature from ComfyUI Essentials for better masks.
