I was impressed but not entirely satisfied with the existing pee and diaper checkpoints, and wanted one that does both well without too much confusion of underwear with diapers.
This model is intended to produce better puddles and wet spots, especially for bedwetting scenes. But it does much more than just peeing. I am calling it omorashi because its a lot better at making people look like they are having an accident or trying to hold it, not just pissing naked in the woods randomly. No shade at the other checkpoints and lora for pee and diaper content, but but I tuned it to what I wanted and felt was not their strength.
I find this checkpoint works especially well with a few more recent related LoRAs, PeeingThemselfV2, and diaperMessV3. It can do what its meant for without either but they are both the ideal thing to add in when you want more pee stains, puddles, and pee streams, or messing respectively. Set them a bit low though, at full power they are likely to be too strong.
If you use this model, it is fairly style neutral and not focused on any particular artists or anything, so it will usually play nice with LoRAs that modify style or focus on a characer. Samples I am posting now ought to show a few examples of that.
For best results stick to lower CFGs, use high res fix but not to much denoise or excessive step count, as it can literally smooth out wet spots entirely or disconnect pee streams. I usually use DPM++ SDE Karras. I usually tested it with the negative embeddings easynegative and bad_pictures, but I imagine that others would work, I just had better results with those.
