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.
