So what's in the bag???

Just like before. I was trying to improve male anatomy aesthetics and Img2Img (where necessary) for oldie but goodie models, namely, Airfuck's Wildmix and Maturemalemix.

TastefullyNude-WildMix - based on Airfuck's Wildmix. Improves genitals at a slight img2img quality cost.

TastefullyNude-MatureYozoraMix - based on Maturemalemix and Yozora Nightsky (12 is for mature guys, 14 is for younger guys; as per Maturemalemix versions). Improves genitals and greatly improves img2img at the cost of Niji face.

And it's not just the name that got updated! All of these new versions feature smaller sized genitals leaning flaccid state. Though, after some testing, it turns out a wild boner appears here and there. But overall, I would advise a different checkpoint if you're looking for spicier imagery.

Oh-So-Protips

• Having problems with images from behind (very likely in Naty versions)? Testicle-vagina-like lumps appearing. There's a work around - Clipskip 7 Inpaint. Set prompt to most basic you can make, aka 'man from behind'. Set Woman Negative Prompt (preferably higher weighted) and nothing else. Set Clipskip to 7 or more and Inpaint at medium denoise (~0.6 and up). Should generate a normal looking male butt in a few tries.

• Checkpoints are quite horny, and often assume 'man' with no clothes described means, 'naked'. Try 'nude, naked' Negative Prompt ('man, penis' if more strength needed) or input some actual clothing articles with extra weight in Positive Prompt.

• MatureYozoraMix12 and MatureYozoraMix14 difference is very subtle. Version 14 produces younger guys and version 12 produces older manlier guys. 14 is also sharper and produces higher quality images on latent upscale.

• All my images are Latent Upscaled with Ultimate SD Upscale Extension for WebUI.

• Recommended Negative Prompt for versions that can produce females 'woman, female, girl, 1girl, vagina, pussy, labia, clitoris' (Wildmix, MatureYozoraMix14, SaturdayMorningSpecial). Because keywords 'nude, naked' bleed between genders, and will mess up genitals.

• Refer to SmallPP Lora for workflow for Inpainting smaller genitals (relevant for Naty versions).

• Non-Naty versions are somewhat harder to get detail into genitals with Inpaint. It's like inpainting hands - you just adjust settings and try until you get something believable. A few arbitrary pointers:

  • If you generated a base image that already has good genitals, then before upscaling it, add 'penis' or 'flaccid penis' in front of the prompt. Details will likely be also quite good.

  • If you generated an image with bad genitals that need inpainting, then inpaint entire genital area, rather than just head, shaft or testicles. SD does not quite have advanced understanding of genital anatomy, even if it does, it's a cluster f*ck of tags.

  • When inpainting, having clean prompt, with nothing but 'nude man, flaccid penis', for example, is more likely to produce easy results, than having ten lines of 'high quality, masterpiece, ultrares and yada yada'.

  • Watch out for lengthy Negative Prompts with a lot of embeddings, they can just straight up remove genitals.

• Want to generate lying down guys? But instead you get upside-down monsters? Try 'couple, upside-down, knees up' Negative Prompt.

• Naty-SaturdayMorningSpecial is GoldenCat based toon mix watered down with a little Maturemalemix, to make character a bit more mature looking. Some arbitrary pointers:

  • Very Negative Embedding sensitive. Mostly flat 2D without embeddings, but easily turns into 2.5D.

  • For good flat 2D feel try 'lips' Negative Prompt.

  • Find strict Anime/Pixelart Embeddings to use for Negative Prompt.

  • Use R-ESRGAN 4x+ Anime6B for latent upscale. Flatter looking output.
