Based on the very well known Lora by titansteng, his incredible All Disney Princess XL LoRA is easily one of the most used on the site, here is my version of it for Illustrious.
There is one little detail: this was trained on Smooth Mix - Illustrious. So I'm not sure how well it works with other checkpoints (nervous sweating:2).
This makes the first time I trained a Lora on one of my own models. As you can imagine, it works very well with my Embeddings and Detail Booster. So try it out.
I'm working on a version trained on base Illustrious as well, just in case this one doesn't work well with other Checkpoints. So keep an eye out! ;)
I'm also curious on how it works on other Checkpoints so have fun testing it out!
Have fun!
