Basic Inpainting Tutorial (Patreon)

People have been asking me for multiple tutorials. I'm taking my time here to make this one that has been even more requested than training tutorial. For me it's a much less complex tutorial too.

Part 1: Fingers

Part 2: Eyes

First let's start with the hands. If you have a finger that you want to fix here is an example.

I've generated a very simple girl grabbing her personality. She has problems in both hands, but I wanted to fix just one for this example. So I sent it to inpainting tab with the same prompts from txt2img.

The image above is the one with no photoshop or outside editor to fix the finger.

(masterpiece), (best quality), 1girl, blonde hair, brown eyes, grabbing own breasts, huge breasts, looking at viewer, smile, outdoors

Note: I have painted her finger and part of the hand with a black paint that's from inpainting pencil.

The negative is the same as I would for normal images.

I'm using the same model from txt2img, but you can use an inpainting version if you want. I can teach later how to create your custom inpainting model, but I don't think it's really necessary.

The settings are literally the same as the default, but you can increase or decrease the denoising strength if you think it's changing too little or too much.

Remember to leave seed as -1, you may need a few tries before getting right. I did it and got at first try, but you may not be so lucky.

I've marked the important parts that you should pay attention for this kind of fix.

Resolution should stay the same as original image.

Result:

Now let's go to part 2.

(yes she is in my next set)

If you want to change the eyes or if they look too blurry, maybe you have a model that can change your character eyes you can use this workflow:

First, I personally prefer to have the image at the highest upscaled size before doing this, because upscaling also changes the eyes. So this image is 2048x3072. It may be too big for your GPU so don't work with too big images if it can't handle.

The settings are different this time.

The focus here should be leaving some style tags and how her eyes should be. I'm using a LoRA to change her eyes to be like this, but normally I just type "green eyes, eyelashes" or something like this beside the usual quality tags. You don't even have to type 1girl.

I have painted her eyes, you can paint even broader, don't be afraid to bleed a little. Just be careful with the denoising strength. I wanted her eyes to change a lot, so 0,5 is a good number, but if you just want to improve her eye quality I suggest something like 0.3-0.4. You can improve the quality of low resolution eyes with this same technique even in a very low resolution image.

The settings are like this. Pay attention to Only Masked. It will basically shift the screen to fit only what you painted. So if you only painted her eyes, that "Resize to" width and height will be only for her eyes. So I have dedicated 1024x1024 pixels for her eyes. If your image is lower resolution you can go with 512x512 or 768x768 and your results will be good too.

Only masked padding pixels can be reduced to 16. I didn't notice much difference from 32, but usually if your resolution is too low 32 will probably blurry things.
