Source description

This assumes you already have the Comfyui Manager installed. If not, you will need to install it first before using this workflow.

Download and unzip the workflow to the ComfyUI/user/default/workflows folder.

Do not launch the workflow yet!

Open the ComfyUI Manager and choose “Model Manager” and type “RMBG” in the search box and install all 4 packages listed. (That will be: ComfyUI-BRIA_AI-RMBG, ComfyUI-RMBG, GFrbmg2 and ComfyUI-Pathway-CutPNG-Node)

Restart and refresh the ComfyUI server and wait for the server to fully load.

Then launch the workflow, upload an image into the fist node and click Run.

The "Remove Background (RMBG)" node will have a green border around it for some time. You will need to wait for the models and dependencies to install. This may take a while depending on your internet connection. Once it finishes your rendered image will appear. It only needs to download the files once.

That's it you’re all set.

You will now have all the nodes you need to build upon this workflow and create something amazing.

Purpose

  • Use Background Remover in ComfyUI to remove an image background with the “Remove Background (RMBG)” node. It takes an uploaded image and produces a rendered image.

Flow

  • The workflow includes LoadImage, RMBG, and SaveImage nodes.

Inputs and outputs

  • Input: upload an image into the first node. Output: a rendered image appears after the workflow finishes.

Setup

  • ComfyUI Manager must be installed before using the workflow; install it first if it is missing.

  • Download and unzip the workflow into ComfyUI/user/default/workflows.

Dependencies

  • The workflow requires the ComfyUI-RMBG node pack at version 2.2.1.

  • The setup instructions list four packages to install: ComfyUI-BRIA_AI-RMBG, ComfyUI-RMBG, GFrbmg2, and ComfyUI-Pathway-CutPNG-Node.

Configuration

  • In Model Manager, search for “RMBG” and install the four listed packages. Restart and refresh the ComfyUI server, then wait for it to fully load.

  • After launching, wait while the “Remove Background (RMBG)” node installs its models and related files; the instructions say the files only need to download once.

Cautions

  • The workflow’s license is not specified.

  • Check the applicable usage terms before using it.
