How to nudify with inpainting correctly ?

Hi everyone,
I’m quite new to Stable Diffusion and I’m struggling a bit with choosing the right models, LoRAs, and parameters to get good results. I’m currently using the "Uber Realistic Porn Merge" model, but the outputs often look weird — the skin is way too smooth, the colors don’t match well with the rest of the body, and sometimes the results are distorted.

I’d really appreciate if someone could share a tutorial or tips from people experienced in NSFW generation, especially on:

How to pick the best models and LoRAs for realistic results

Which parameters (CFG scale, denoising strength, mask blur, etc.) work best

How to avoid common issues like oversmoothing, color mismatches, or distorted images

Thanks
