Runtime44 ComfyUI Nodes Introduction

The comfyui_r44_nodes extension is a powerful toolkit designed to enhance your image processing capabilities within the ComfyUI environment. This extension provides a variety of nodes that can be used to upscale images, match colors, apply masks, and more. Whether you're an AI artist looking to refine your creations or someone who needs to automate image enhancements, comfyui_r44_nodes offers a range of tools to make your workflow more efficient and effective.

How Runtime44 ComfyUI Nodes Works

At its core, comfyui_r44_nodes operates by providing specialized nodes that can be integrated into your ComfyUI workflows. Each node performs a specific function, such as upscaling an image or matching its color to a reference. By chaining these nodes together, you can create complex image processing pipelines that automate tasks and produce high-quality results. Think of each node as a building block that you can combine in various ways to achieve your desired outcome.

Runtime44 ComfyUI Nodes Features


  • Description: Upscales an image in pixel space using an upscale model.
  • Customization: You can select the upscale factor and tile size.
  • Example: If you have a low-resolution image, you can use this node to increase its resolution while maintaining quality.

Iterative Upscale Factor

  • Description: Determines the upscale factor based on the index in the chain.
  • Customization: Adjust the index to control the level of upscaling.
  • Example: Useful for progressively upscaling an image in multiple steps.

Color Match

  • Description: Matches the color of an image to a reference image.
  • Customization: Provide a reference image to match colors.
  • Example: Ideal for ensuring color consistency across a series of images.

Dynamic KSampler

  • Description: Uses multiple samplers during the diffusion process.
  • Note: This node is still a work in progress.
  • Example: Can be used to experiment with different sampling techniques to achieve unique effects.

Mask Sampler

  • Description: Targets the diffusion to a masked region.
  • Inspiration: Inspired by Impact's SEGS detailer.
  • Example: Useful for applying effects to specific areas of an image.

Tiled Mask Sampler

  • Description: Similar to the Mask Sampler but uses a latent tiling system.
  • Example: Helps in processing high-resolution images without running into memory issues.

Image Overlay

  • Description: Adds an image on top of another, useful for watermarking.
  • Customization: Adjust the position and transparency of the overlay.
  • Example: Perfect for adding watermarks or logos to your images.

Image Resizer

  • Description: Resizes an image to a specific resolution while keeping the aspect ratio.
  • Customization: Specify the target resolution.
  • Example: Useful for preparing images for different display formats.

Image to Noise

  • Description: Converts an image into latent noise.
  • Example: Can be used as a starting point for various noise-based effects.

Image Enhance

  • Description: Changes the brightness, contrast, and saturation of an image in pixel space.
  • Customization: Adjust the levels of brightness, contrast, and saturation.
  • Example: Enhances the visual appeal of your images.

Film Grain

  • Description: Adds film grain to an image in pixel space.
  • Customization: Control the intensity and pattern of the grain.
  • Example: Adds a vintage or artistic effect to your images.
