What is outpainting?
outpainting is a technique to draw the "outside" of an image.
The content is exactly the same as inpainting's "Type B: Fill the masked part naturally while looking at the surrounding information".
The only difference is whether the mask is inside the image or outside.
We will proceed assuming you have read inpainting first.
inpainting Model
A straightforward method using an inpainting model.

- Almost the same as inpainting/inpainting Model.
- 🟦 Expand the image outward with the
Pad Image for Outpaintingnode.- The expanded part is output as a mask.
- 🟩 Just connect it to the
InpaintModelConditioningnode.
ControlNet inpaint
If you want to use your favorite model as is, use ControlNet inpaint.
