Whenever you generate images that have a lot of detail and different topics in them, SD struggles to not mix those details into every "space" it's filling in running through the denoising step. Suppose we want a bar-scene from dungeons and dragons, we might prompt for something like

"gloomy bar from dungeons and dragons with a burly bartender, art by [insert your favorite artist]"

Which results in an image as follows, maybe:

​

Original SD image

Now I like the result, but for me, as happens a lot, the people also get lost in the generation, and while the impression is nice, it lacks a lot to "make it usable".

img2img-inpainting to the rescue!

With the web-ui, we can bring those people to life. The step is fairly simple:

1. send the result to im2img inpainting (I use automatic1111s version of the gradio-UI)
2. draw a mask covering a single character (not all of them!)
3. change the prompt so it matches what you want, e.g "red-haired warrior sitting at a table in a bar" for the women (?) on the left
4. keep the strength above 0.5 to get meaningful results
5. set masked content to "original"
6. select "inpaint at full resolution" for best results
7. you can keep the resolution at 512x512, it does *not* have to match the original format
8. generate

The results are cool, SD has rarely been a "1 prompt and perfect result" tool for me, and inpainting offers amazing possibilities.

After doing the same thing for all the characters (feeding the intermediate images back to the input), I end up with something like this:

Inpainted version

It's a lot of fun to play around with! The masking via browser is sometimes fiddly, so if you can, use the feature to upload the mask from an external program (you can use GIMP or PS to have the masked area filled in white and leave the rest black).

You also don't have to restrict it to just people, you can re-create parts of everything else aswell:

Look, a new door, and a dog and guard become visible!
