A lora for doing ring transformation where the act of passing through the ring changes the subject to another form.
The main tags are (R1ngTF), (transformation), and (hoop). I chose hoop because ring kept adding rings to the fingers. Despite not being a tag in the training images, (glowing hoop) seems to make it work better sometimes.
Subject order is important, the lora will usually try to make the first included subject the upper half, and the second one the lower one.
If both characters heads are in the image I recommend lowering the strength of the intended lower half either with [brackets] or moving it later into the prompt.
The best way to make it work is to pick two subjects and then include tags for the body parts you want for each side. For example, mixing a fox and an alligator wanting the fox on top, include things like (orange head), (orange arms), (white chest), (green legs), (green tail), (green feet).
You can get really specific with it if a specific pose isn't working! Tags such as (fingers), (forearms), (hands), (thighs), (stomach), (neck), should all be innate with illustrious and help you fine tune your images.
It will usually place the ring in the middle but it seems to be smart enough to adjust the ring to other heights if the proper amount of tagging is included.
It's also very good at mixing two furry bodies, but getting a human upper body with a furry lower body is a little more difficult than the other way around.
Adjust strength as needed, seems to work with a pretty wide range without too much effect on style.
