Krea 2 Lora Training Questions
So, I'm trying to improve my Lora training for Krea 2, because while I'm able to train basic style/character/concept loras, the problem I have is that they're all too rigid, and not in the way of being overbaked.
As it turns out, Civitai removing all their real people loras entirely decimated the ecosystem and knowledge for training characters that have specific looks or multiple outfits. Which is kind of the issue.
For example, I could easily train just the armor for Iron Man, but the problem is that it bakes in that look, and then when I do what I've done in the past with other models, which is add more variation to the dataset, it only seems to take away from everything. Ergo, iron man suit 1 works, iron man suit 2 works, iron man suit 1 and 2 takes away from both likeness wise.
And this is an issue because I'm not sure how to A. capture the outfit/concept without B. losing the likeness/flexibility. My assumption was to use a trigger word, again like other models, but the issue was that doing so didn't really train much of anything it seemed?
Is this just a dataset issue? Like do you basically just need, like, 20-30 images for each individual concept? Normally a lora might only need around 20 images total, but with more concepts you need more data. But is this a case where you need closer to 100 images, in order to have clear concepts? Or is this a case where having more images means that the model sees each image less, and thus it learns it less well?
Not sure how to really create the flexibility I'm looking for without either A. baking in the costume as concept or B. muddying the training and causing it to learn things poorly.
