Workflow plus custom node for Krea 2 NSFW.

Credits: https://github.com/nova452/ComfyUI-ConditioningKrea2Rebalance

To activate the custom node just copy ComfyUI-ConditioningKrea2Rebalance folder (included in the zip) to your ...\ComfyUI\custom_nodes\ folder and restart ComfyUI.

Change the resolution if it doesn't work for some specific prompt and try again. The NSFW training data is in the model out of the box (even very hardcore), just try different seeds/resolutions/prompts and it should work about half of the time. You could also experiment with the "multiplier" option - anything from 0.80 to 20 (2 or 4 is ok). Higher resolutions (like 1344x2048, 1920x2048) seems to require stronger multiplier (2.75 or more) - you could fix a seed and find out what is the minimal value that works for a specific resolution. Haven't done much testing, so I'm not even sure if the resolution and the multiplier are connected, but this is what I get.

Kudos to the Krea 2 creators - they ain't stupid/afraid, which is a rare exception nowadays.

Sampler + schedule: euler + simple
