Round Breasts - Flux

V1.0

This is my first try to make a LoRa at all and for Flux. I am testing to make a LoRa for round fake Breasts.

This LoRa need no Triggerword.

I have testing and Weight range is 0.70 to 1.0.

At the moment i have not so much control of the LoRa to control the breasts size. But im still working on it. Version 2 :)
---------------------------------------------------------

V1.1

My second attempt.

I wanted the LoRa size to be smaller and that the LoRa reacts to Small, Medium, Large breasts when it is written in the prompt.

It also has trigger word “roundb”. When the trigger word is used I have the feeling that together with small, medium and large does not really work well. It's more of a coincidence what it takes.

This is probably due to my captioning. Without the trigger word, it works a little better with small, medium and large breasts in the prompt, but I'm still not satisfied with it. I still have to test the image selection for training.

I have also tested several methods to create a LoRa.

My first attempt was locally with AI-Toolkit with about 50 images. The images were cropped to the breasts.

My second attempt was local with a Comfyui workflow. Unfortunately, this did not work for me. I think becouse my lack of knowlegde. ;)

I made this attempt with CivitAI. There were 119 pictures with the whole person on it.

Just try it out for yourself. I'll keep working on it. There is still so much to learn and test. Unfortunately, that always takes a lot of time :)

For those who are interested here the training data of version V1.1

Edit: Don`t use "girl" in the prompt. It seems that Flux don`t like that with round breasts. ;)
