I'm back! Yesterday I attended a web seminar to learn more things about that newfangled Character Reference feature.
Apparently I can make a full-fledged reference sheet just from a single portrait shot?!
Here's a test I did with Emily Tauriel (a PNGTuber), using only her 400px profile picture.
It's not 100% on model... but that's still pretty neat! I'm not sure if this helps with making LORAs for you guys, but apparently it's a thing it can do.
