Updated to V1.1:
Keeps the same texture, lighting and moodiness from v1.0 but is now slightly better at generating consistent and coherent anatomy. Also has better eyes, finer details (e.g. skin), and better contrast and shadows. Does not improve on all aspects of v1.0, so you'll have to experiment to see which you like best.

This is a photorealism model merge using (block) DARE ties w/model masking. It was tailored to produce slightly darker and grungier images, which is my own stylistic preference. I'm primarily releasing this for friends who've been asking for it, but also anyone else who is looking for a "moodier" realistic model that has good skin texture, lighting, and prompt adherence, but doesn't want that "Pony" look. No Pony derivatives were merged into this mix (v1.0). If you like the types of images that I generate, you'll probably like this model too. Good for both sfw and nsfw.
Many of your favorite realistic models are included in this merge to some degree, so expect similar results. It has been tested against other popular merges with X/Y plots and is able to generate unique output. Great for selfies, polaroid-style images, and analog shots in general. Good for upscaling too, though perhaps not as good as the incredible Lustify at the latter. It gets skin color/tone right most of the time. Its weaknesses are eyes (which is an easy fix with a detailer) and the occasional floating wang. Also not great for anything too fantastical. Overall its pretty good, and once in a while knocks it out of the park. Have fun with it. And remember, you get what you pay for.
The example images include a basic Comfyui workflow that I whipped up to help you get off the ground. XXX-Ray has been tested in ReForge as well and works as intended with the suggested settings below.
Some advice for its use:
Use PAG (Perturbed Attention Guidance) at ~1.5-2.0. It will significantly increase the quality of your output.
Asp tokens were kept intact as best as possible in the merging and work well: (https://gist.github.com/fpgaminer/0243de0d232a90dcae5e2f47d844f9bb).
The Detail Daemon sampler (~0.04), like PAG, will boost output quality.
Using score tags (e.g. score_7_up) will affect your generations slightly, but they are not strictly necessary.
Use the included comfyui workflow if you're having issues: https://civitai.com/articles/9981
Upscaling is your friend. This is also included in the provided workflow.
Settings that have worked well for me with this merge:
DPM++2M sde Karras at 23+ steps, DPM++ SDE Karras at 18+ steps, or DPM++2M sde AYS at 14+ steps.
CFG ~4.0-4.5.
PAG (strongly recommended) at 1.5-2.0.
