UmeAiRT outpainting simple workflow

I am pleased to share with you my new outpainting workflow.
Select an image, set the ratio and position of your image in the new one, and a preview will appear just below.

The upscaler adds detail and corrects joins between the original image and the new one quite well.

The easiest way to install all the files needed for workflow use is to use one of my installation scripts or my manager.
In general, you're missing the “RV-Tools” node, which is not detected by ComfyUI manager. You can find it in “Custom node manager”.

To install the missing nodes, I created a script : ComfyUI missing nodes auto installer - v2.0 | Flux Other | Civitai

I've written a complete guide to its use: link
