Using the dataset and script from https://civitai.com/user/seruva19 (Please give him all the credit)
In this Lora, https://civitai.com/models/1753118/anime-denser-wan21-t2v-14b
This is Hidream version of that same concept lora -3 strength less density +3 strength more density.
I used ai-toolkit to train both the positive and negative lora's and used the same difference_lora.py script to make the final lora.
* The only change I had to make for the difference_lora.py script was change the ".lora_down.weight" references into ".lora_A.weight" references (different names but same concepts).
