Since original creator did not really document the nodes and Models, to make his Flux model "FLUX.1-Krea-dev Uncensored" work or how the demo pics were created, I traced it back and put the Download Links to the included 2 LORA and 2 CLIP models in a ComfyUI Note.
Remark: I would suggest not using the 2 LORAs though, especially the pussy one, they significantly lower image quality. If you have to use one, try NSFW alone at 0.7-0.8, should be enough.
