I release a new checkpoint merge, focused on the "film noir" aethestic. I managed to make it pretty robust, but colors might go back if you add them to your prompt. Tell me if they go back even when you didn't.
I try to think what such a LoRA could generate (since "film noir" is not just "black&white pictures"), so feel free to give me any constructive feedback about this ! I'd recommend so far :
1024x1024 at least (consider Hi-Res).
CFG 4-5
DPM++ 2M or Euler a
Sampling steps 25-30
