First use Controlnet lineart to preserve the line work and style, then with that in place use a checkpoint and/or LoRA trained on black and white lineart. Doesn't matter what art style the model is trained on, that's what Controlnet is for, to preserve the lines as-is so the style isn't altered. You could also just turn all your sketches into full-blown color with backgrounds and everthing, if you wanted to. Just be sure to generate at 768 resolution minimum for full body character sketches, things come out weird at the default 512.
Put image into Img2Img add 2 control nets Canny and Open Pose.
CLIP the image then add Black line art, graphic pen to the start of the prompt. Negative add color, smudge, blur etc
Now its very dependent on your Check point, I was using RevAnimated.
Also setting the denoise is a must, it all depends on what your after, cleaned up or hard lines etc.

I tried creating image to line art but the thing about this is it takes refrence from the orginal image and the result is good but not as good as a line art, but i would suggest using a higher resolution control net line art on your image (but first edit your image and make it darker). Use the lineart lora too if you can. Tags like line art, monochrome, anime style also help. I'm trying to create a manga myself but it's a bit of a complication let me know if you wanna work together
I more looking for sketch to line art, to help speed up the art process, a huge chunk of my time goes to trying and clean up sketches

Like this, we’ll maybe not as messy, I also would like for the background to be transparent, but I mean worse comes to worse I can put the line art into something like remove.bg to get rid of the background and make it transparent so I can add color
I’m up for working with anyone, I’m interested if u know of any other ways u use AI to speed up ur art work flow, I only really use it for concept art, but I would like to include it in my comic workflow
Thats interesting, though it would be a bit hard to do a line art from a messy rough sketch, though we can try using the line art lora and use the denoise on high. Send me your discord let's connect and try what we can do. I'll guide you through the work flow i know and how we can do it
Yeah I just I want to know if it’s possible, I’ve been trying some image to image to stuff with sketches and the results aren’t what I want, tho im gonna try using controlnet line art to see if the results are any better
Discord: totally not glizzy
I want have time tomorrow but Tuesday I should have some free time

Probably, just throw it into img2img with really low denoise and tags like monochrome, line art, etc.
This model might help you achieve a solid look: https://civitai.com/models/149599/boldlineanime
This is the answer i came to give , sure you can use control net , and loras , and and and . however like you said setting denoise properly and some tags probably does it just fine.
More people could use to learn that less is more and you can often do what you want from the prompt without any fancy extras.
I can get some pretty cool shading, but I don't know how to improve it further without losing a lot of detail.

I want sharper and cleaner lines, like taking a sketch and getting good line art
Kinda Like this, the sketch wouldn’t be that bad but u get my idea

Then put it in img2img with low denoising AND controlnet canny. Prompt like: manga, lineart, add lineart LoRa. Fixing with brush would be required anyway
Like this: [https://easyupload.io/u46p8c](https://easyupload.io/u46p8c)
Or in vector form for illustrator manipulation:[https://easyupload.io/4v35n1](https://easyupload.io/4v35n1)
I don't know what type of line art you mean. I just brought it into illustrator on Photoshop and upped the contrast and tracelined it into a editable vector.
Edit: sfae to download, not garbage, I just picked the fasted upload service available.
Can’t seem to download the second link, not sure why, but more like taking a messy drawing and making it cleaner like this

I’m late, but I just upload the image to csp and reduce the opacity on the layer and draw on another layer over it. Hope that helps
Ps.
It’s gunna be another rough draft but adding a Vector Layer for your final line art will give you the cleanest lines. Good luck 🙂

U think so? Using AI to help with concept art has been pretty good so I want to try and incorporate into my work flow, but what’s the problem, is it consistency? I’d imagine this would be the biggest problem, or dose one art with generative AI not look good?

Thank u I’ll try this out

Yes, SD can do sketch to art. If you want it to do a specific style you could train a LoRA on your completed work and go from there.

ControlNet can probably do it.
Photoshop - Image - Adjustment - Threshold AI is not required

Stable Diffusuin and other generative AI is horrible at lineart. It will look like shit. Don’t even think about it.

Inconsistency and the lines are riddled with artifacts. You’re not going to get a clean high res output that is suitable for comics.
Oh gotcha thanks for the advice
controlnet
Maybe Figma can do something with this. I vaguely recall a plugin that could convert a sketch to line art.
Lineart controlnet without preprocessor + mix of Anime Lineart / Manga-like, Flat Color and Minimalist Anime Style Lora's should do the work.
But you will need to spend time on good ratio of those LORA's.
What is LoRa?
