TL;DR: quick fix "patch" LoRA to try and get better hands if stuff went wrong :D Will not do magic, but can help without breaking the original picture too much. Can be used as-is at base strength 1.0 or adapted between 0.8 and 1.2 if needed.
I am releasing the 2 versions:
2generate: 32 dimensions version that can be applied on the fly during generation
4merge: 128 dimensions version to be used for merge in checkpoint if needed
NB: I have marked this model as Illustrious to allow usage in the Civitai Generator since the other "Hands" LoRA i found are marked either as Pony or SDXL1.0, but this should work with any SDXL based model :D
Update: to help with Civitai Generator, i released the exact same file as 2generate tagged as a Pony LoRA. If you don't use the on-site generator, this "Pony" version is not needed if you already got the 2generate for Illustrious.
