Hello!
Here is the guide some people requested :-)
https://rentry.co/lycoris-and-lora-from-dreambooth
This is how I make my LyCORIS models.
The zip file that you can download contains the mp4 video tutorial part of the guide. You do not need to download it, it is also available online if you check the rentry page :)
EDIT: there is a second version called "Base Model in Diffusers" - this contains the exact model (based on RV2.0) that I use for my training.
Enjoy!
