    SD seems to love big breasts. But not all people prefer them too. Even most of the NSFW Lora's for SDXL only produce big ones. This is a Lora for really small breasts.

    SD 1.5 Version: https://civarchive.com/models/285031?modelVersionId=320676

    Read the "About this version" to get the best results.

    I have nothing against 5* ratings, but please refrain from doing so if this LoRA has obviously not been used...

    I recommend a strength between 08 and 1.25.

    I strongly recommend the "flat chested" versions. Other versions are experimental.

    Hopefully it is clear that this LoRA may not be used to create underage or otherwise illegal content

    Feel free to share the images you created with this LoRA if you like. I'm excited to see what others here have done with it.

    There are not many tutorials for training NSFW stuff. So I am absolutely no expert either.

    For this LoRA everything in the image was tagged except for the breasts. For the head I made it easy and it was either not on the pictures or I just tagged it with "head". Not much different than for SFW stuff.

    Description

    trained on 170 images. For this version i recogment a strenght of 1.2

    not really. 32 or 64 dim is plenty for 99.9% of concept/characters loras. 128 is only needed for styles.

    Try and retrain with 32dim. See if you can tell a difference. If not, congratulations; you just cut the thiccness by 400%.

    @petardapocpocc I'm an idiot. I forgot this was XL.

    Is it possible to train SDXL on skin texture? This is the main problem for photorealism right now.
