(Updated Nov 11 2025)
I just realized that I may have set the UNet learning rate too high (0.0005) in version v1
I updated the model (v1b) by keeping the same dataset and parameters as v1, and simply reduced the UNet learning rate to 0.0002
Compared to v1, it seems to produce good results even without using ControlNet (I haven't tested it yet)
Feel free to use it if you need
For me, one of the problems using Stable Diffusion is that when I want to generate a character wearing tokusatsu or sentai bodysuit without helmet, the bodysuit often doesn't fully cover the neck skin even "turtleneck" is added in the prompt
Personally, I CAN'T ACCEPT THAT
This Lora tries to fix the problem but it's not perfect
Trigger word: covered neck
Also add "(color) neck", "(adjective) neck" if necessary
Weight: 0.8-1
Recommend to use with ControlNet Canny. For details, see HERE
You can use it as usual, but it may change the output of the image completely (this is the biggest issue)
It was not tested on male characters. It may work fine or not
