I am not the author, uploading here for I believe... sharing is caring ;)

Original post was from: https://civitai.com/models/1388271/nj-vector-style-illustrious?modelVersionId=1568905

Usage, regardless of underlaying model

(this is my recommended settings, you are free to test other stuff 😉 )

• Euler a + Beta

• 40 steps

• CFG 4

• Clip Skip 2

• Beware of the denoising strength during Adetailer et Hires.Fix. Keep it low, like 0.15 max.

• Negative prompt: IllusN3g , and optionally " 3D " depending on the base model.

• Positive prompt:

  [whatever you want], Flatline, Flat vector illustration, Black outline, Vivid colors  <lora:NJ_Vector_Style:1>

In the showcase, you'll find tests with my own checkpoints and several popular others to see the effect, including:

• IXL_AnyLoRA <= for the more simple cute style ❤

• AlterBan V3

• Quirk V2

• WaiNSFWillus

• HassakuXL

• SmoothMix

• iLustMix

• Animij <= gives very good results too 🤩

Basically, the simpler and more anime like the model, the "cuter" the effect. But with more "aesthetic" models, included NoobAI, you still get good 2D results :D

PS: it does not work well with a V pred model, sorry! You can still try, but then, be sure to switch to Euler + Automatic and the result will be... kinda psychedelic ^^;


The Story™

So, i really liked this LoRA by MrLoreTaker , but several points bothered me:

• The overall hue is a bit too shifted

• Strength 2.0 is needed and if you don't RTFM, you can miss it

• The LoRA internal architecture was a mess! What The heck is an "sdxl_a1111_compat" LoRA?!? Why is a 16 dim LoRA so heavy? Why do i get some warning/errors when using it sometimes?

So, here is my manual rework on top of his great work:

• Remade from scratch LoRA architecture, now a correct 16 dim LoRA and not a MB more.

• Adapted weights for hue/saturation. SVD to the rescue. Manual Python and Pytorch stuff all the way, i really hacked into it for fun and learning a bit more this stuff.

• Fixed needed strength. Works out of the box at strength 1.0

It took a while to make it cleaner/more to my own taste, Enjoy!

NB: when using this LoRA in a merge (if ever), please credit the original author MrLoreTaker instead of me (if you do things by the rules, otherwise, you aren't reading this anyway isn't it?)
